11 1. General Use approved hoisting points and certified lifting equipment of sufficient capacity. Make sure that equipment can neither tilt nor move during lifting. Make sure there is sufficient space and that persons are in safe positions. Make sure that you shut off the prime movers and all pumps, disconnect the electric power supply and close all relevant valves when you work on equipment. Make sure that the prime mover cannot be accidentally started. Put warning signs in position. Make sure that no one is working on the equipment before starting the prime mover. Do not, under any circumstances, start the prime mover or operate equipment when a warning sign is attached. Make sure that high pressurised oil can not leak. Place protective guards in position. Always wear safety glasses and protective clothing when you work on equipment. Oil pipes or hoses of insufficient strength can burst under pressure. Severe injury can result. Do not disconnect hydraulic pipes or hoses when pumps are operating. Make sure that all protective guards and covers are correctly installed. Make sure that rotation by gravity is not possible. Make sure that uncontrolled rotation of the hub and propeller shaft is not possible during launching and outfitting. Do not mix metric fasteners with other (standard) fasteners. Mismatched or incorrect fasteners will cause damage to or malfunction of equipment or can result in injury. Disconnect the mains and back up power supplies when you work on the remote control and put warning signs in position. The propulsion control system is always under live voltage. Disconnect interface circuits that are under voltage from other power supplies Cautions Always attach lifting equipment to the lifting points or to places indicated on the (transport) drawings. Use shackles or slings. Do not attach lifting equipment to machined surfaces, shaft ends, piping work or other externally mounted equipment. Make sure that you place a sufficiently sized oil or fluid catch tank(s). Always collect and remove spilled oil or fluid from (dis)assembly procedures. Make sure that you drain system oil or fluid before equipment disassembly. SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

12 1. General Make sure there is no dirt or external material in the hydraulic or lubrication systems. This can cause extensive damage to equipment. Do not use alkaline or chemical detergents to clean rubber, synthetic or painted components. They can cause damage to equipment. Wipe with a dry cloth only. If pressure pumps are installed in parallel, make sure the hydraulic system is designed for this purpose. Check the hydraulic system first. Simultaneously running the two pumps can cause serious damage to equipment. Always earth screened cables exclusively at cabinet side, never at panel or component side. Electric welding introduces spikes. Always disconnect the mains and back up power supplies to the electronic cabinet or to components close to the welding area. Do not use control panels or electrical cabinets as an earth point when welding, this can cause damage to electrical components. When welding, always connect to a good earth point close to the welding area to avoid damage to equipment surfaces. When welding, protect the surroundings from welding spatters. 1-4 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

17 2. System Description 2. System Description 2.1 Tunnel 2.2 Propeller The transverse thruster transforms power from the prime mover into a thrust force in the starboard or port direction on the ship. The transverse thruster system mainly consists of a tunnel, a right-angle gearbox, a controllable pitch (CT) propeller, a flexible coupling, a prime mover, a hydraulic system and lubrication system and a propulsion control system. The right-angle gearbox with propeller is mounted in a tunnel that connects port and starboard side of the vessel. The tunnel is welded to the hull forming an integral part of the construction; in special designs (low-noise and/or mountable tunnel), the central part of the tunnel containing the right-angle gearbox with propeller is bolted to a frame. The propeller transforms the torque from the prime mover into the thrust force on the ship. The propeller consists of propeller blades and the hub. 2.3 Right-angle gearbox The shafts and bevel gear set, inside the right-angle gearbox, transmit the torque and reduce the revolutions of the input shaft. The right-angle gearbox is bolted to the mounting flange in the tunnel. 2.4 Flexible coupling A flexible coupling connects the prime mover shaft (occasionally the intermediate shaft) and the pinion shaft. In most cases, the flexible elements of this coupling can be replaced without disconnecting the shafts. 2. Prime mover The prime mover delivers the power to the transverse thruster installation. In most cases, the prime mover is an electric motor. Alternatives: hydraulic motor or diesel engine. 2.6 Hydraulic system and lubrication system The main function of the hydraulic and lubrication system is to supply the hydraulic power for pitch control of the propeller blades and lubrication for the gearbox. To prevent oil leaks and water to enter the system, the hydraulic and lubrication system keeps static pressure onto the seals. Optionally the hydraulic and lubrication system has: a header tank, to apply sufficient static pressure on the seals when the hydraulic power pack cannot be installed at the required height above the waterline; a pressurized header tank, required pressure is controlled by a pneumatic pressure control unit; a hand pump, to drain and to fill the lubrication system by hand; SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

18 2. System Description a drain and fill valve, to drain and to fill the lubrication system with the help of an external pump set. 2.7 Propulsion control system The propulsion control system transmits orders from the control station in command to the thruster installation. 2-2 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

19 3. System Operation 3. System Operation For the propulsion control system, consult separate manual for controls. 3.1 Introduction Before starting any action, the transverse thruster system must be fully understood by the operator. If you have any questions, you can ask Wärtsilä for help before you start any action. Do not sail the ship if function and operation of this equipment are not clearly understood. For a complete overview of the total propulsion control system, consult the instruction manual(s) of the propulsion control system. Troubleshooting Follow the directions of Chapter 4. Troubleshooting. Emergency operation When there is a problem with the propulsion control system only, the transverse thruster can be operated by hand. See: Instruction: Emergency operation, chapter 3.4. Review all levels of emergency operation once a month. 3.2 Prepare operation of mechanical part of transverse thruster For detailed procedures and instructions of the propulsion control system, please refer to the applicable manual. 3.3 Normal operation instructions For detailed procedures and instructions of the propulsion control system, please refer to the applicable manual Pitch-to-zero operation WARNING The hydraulic power pack can start automatically to deliver the pressure for the Pitch-to-zero system. If the thruster is not in use, the automatic Pitch-to-zero system comes into operation to prevent trailing of the propeller. To enable the Pitch-to-zero system to operate correctly, it is necessary that the hydraulic power pack is set to on. 3.4 Emergency operation When the prime mover, the hydraulic system and the thruster can operate under their normal conditions and there is only a problem with the propulsion control system, or interface between SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

20 3. System Operation the control units, the prime mover and the hydraulic system, it is possible that an engineer operates the transverse thruster by hand. However: When the problem is already known by the ship's crew, we strongly recommend calling assistance from tugboats before (un)berthing operations start. This to minimise the risk of damaging the ship's structure. 3-2 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

21 4. Troubleshooting 4. Troubleshooting 4.1 Troubleshooting charts Troubleshooting for the transverse thruster Introduction Read the preface and all chapters of the operation manual before starting any action. Only allow qualified and trained personnel to work on the equipment. This chapter provides an aid for troubleshooting. On several occasions reference is made to the Maintenance chapter. Keep records in the machinery journal of all troubleshooting actions or anything unusual. See the appendix, journal and ordering notes. Respect the maintenance intervals. Regular maintenance improves operational safety, reliability and decreases the long-term maintenance costs. WARNINGS! Always be careful when you work around rotating components. Make sure that you shut off the prime movers and all pumps, disconnect the electric power supply and close all relevant valves when you work on equipment. Make sure that the prime mover cannot be accidentally started. Put warning signs in position. Make sure that no one is working on the equipment before you start the prime mover. Do not, under any circumstances, start the prime mover or operate equipment when a warning sign is attached. Make sure that high pressurised oil can not leak. Place protective guards in position. Always wear safety glasses and protective clothing when you work on equipment. Do not disconnect hydraulic pipes or hoses when pumps are operating. Disconnect the mains and back up power supplies when you work on the remote control and put warning signs in position. The propulsion control system is always under live voltage User group Wärtsilä Service & After Sales Department(s) are available to provide advice and assistance. This chapter is intended for the ship's operating staff and the ship's engineering staff. SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

29 . Preventive Maintenance. Preventive Maintenance This chapter gives the maintenance intervals and related checklists for the preventive maintenance tasks for the Wärtsilä scope of supply. The maintenance intervals are meant as an advice and a help for the planning of the preventive maintenance tasks either in dry dock, on-board or spare part storage. For future reference, put a copy of the completed maintenance checklists in the maintenance logbook. If a task can only be done professionally, please make, well in advance, an appointment with the Wärtsilä propulsion service organisation. The given maintenance intervals are the result of condition-based maintenance analyses and give a minimum level of maintenance. You need to review and revise the maintenance intervals in accordance with the operational use and conditions. The maintenance intervals are defined as: Symbol D M Q 6M A Y O MR Interval Daily Monthly Quarterly 1/2 Year Annually Year Overhaul 300 hours Description When the thruster is in use. One time in a month. One time in 3 months. One time in 6 months. One time in 12 months (1 year). One time in year. One time in 10 year. After commissioning or after an overhaul of the transverse thruster, or when the oil system was opened for inspection and repair (known as major repair). The maintenance locations are defined as: Maintenance task is possible when the vessel is in the water. Maintenance task is only possible when the vessel is in dry dock or in trimmed condition..1 Preventive maintenance at progressive intervals Preventive maintenance at progressive intervals means that you do the preventive maintenance of the nearest intervals during the (un)scheduled maintenance or repair of the vessel s equipment. The preventive maintenance intervals tell you which inspections and tests must be done at which moment at least. However there can be unscheduled moments in between these intervals. If the vessel is in dry-dock for whatever reason, it is recommended and cost efficient to do the (dry-dock) indicated inspections and tests at that unscheduled moment, but make sure the given inspections and tests are done at least one time per interval.

53 6. Tunnel and Thruster 6. Tunnel and Thruster This chapter contains detailed instructions on installation, maintenance and disassembly of the transverse thruster, its drive shaft and assembled components. 6.1 Installation procedures Mounting of the pod with hub into the tunnel Instructions regarding the installation of the pod Receiving the transverse thruster's pod Special reference is made: To the installation drawings, which can be found in the chapter "Tunnel and Thruster". In order to ensure that no mix up of components occurs between FWD/AFT stern and bow systems, it is important to make sure that the order identification numbers, engraved in the components or on the type plates, are in accordance with the identification numbers on drawings and instructions in the manual Checklist for mounting the thruster unit See for instructions the section "Tunnel and Thruster - Installation procedures" and the drawing: Assembly of the Pod. All hoisting equipment must have sufficient capacity (taking into account normal safety factors for hoisting). All hoisting equipment must be of good quality and must be checked for proper functioning. Table 6-1 Checklist mounting thruster unit* Activity number Activity Check Remarks 01 Make sure the thruster will be mounted in the correct tunnel 02 Check the hoisting equipment for capacity 03 Make sure the hoisting equipment is functioning 04 Make sure the mounting faces are cleaned 0 Mount the thruster with the flange sealant use Loctite Torque on flange bolts Nm see drawing: T / T Mount and weld the foundation plate between the pod and the tunnel according to the instruction 08 Drill the positioning spring dowel in the tunnel 09 Cover the feedback seal on the top flange (cotton+tape) SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

54 6. Tunnel and Thruster *If more than 1 transverse thruster is installed, make a copy of this table (one for each installation) Table 6-2 Special tools None Mounting instruction of the pod Item numbers refer to the drawing "Assembly of the Pod". 1 Clean the connection faces thoroughly. All mounting faces of gear pod and tunnel must be absolutely clean. 2 Lubricate the O-ring (2) with grease T (Molykote 111) and mount it into the groove of the pod flange. 3 Apply liquid gasket onto the mounting faces of the gear pod and tunnel. 4 Take special care not to damage the mounting faces while transporting the pod into the tunnel. Position the pod in the tunnel, lubricate the mounting materials with grease T (Copaslip), to prevent scoring and mount the screws, spacers and washers loosely into the threaded holes of the pod flange. 6 The position of the pod must be adjusted in such a manner that: The centre of the propeller is aligned with the centre of the tunnel. The centre of the pinion shaft is aligned with the spigot of the prime mover. This is done by measuring the clearance between the hub and the tunnel as well as aligning the pinion shaft to the prime mover support. 7 Measuring the alignment of the pinion shaft to the spigot of the prime mover is done, by placing a dial gauge between the pinion shaft and the spigot. The spigot for the prime mover has, in most cases, some clearance to compensate for any remaining misalignment of the pinion shaft. NOTE To determine whether the spigot for the prime mover has a tight fit or not, you must check the tolerance on the drawing Arrangement Transverse Thruster. If the spigot has a tight fit (like on installations having an intermediate shaft), the allowed misalignment of the intermediate shaft often is sufficiently large to compensate for any remaining misalignment of the pinion shaft. 8 Tighten the screws with the prescribed torque (see the drawing Assembly of the Pod ). 9 Check if the mounting surfaces of pod and tunnel are put together properly using a feeler gauge of 0.03 mm. 10 Drill two extra holes in the prime mover foundation for spring dowels, for demounting and mounting purposes in the future; see detail, on the drawing "Arrangement of Transverse Thruster". 11 Secure the screws with locking wire diameter mm (4). Try to keep the weld free of the tool edges in order to simplify disassembly. 12 Mount the lubricating oil and hydraulic connections according to the drawing Lubrication Oil and Hydraulic Connections". 6-2 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

57 6. Tunnel and Thruster Mounting the pitch feedback Wiring the pitch feedback junction box. Usually the pitch feedback-potentiometer(s), rod and junction box are already mounted on the motor foundation and completely wired; see the drawing: "Arrangement Feedback". Make sure that all preparations in the preparation list are made before starting this activity. To ensure that no mix up of components occurs between AFT/FWD and bow/stern systems, check that the order identification numbers, engraved in the components, are in accordance with the identification numbers on the drawings and instructions in the manual. Table 6-3 Checklist pitch feedback installation No. Activity Check Remarks 01 Required parts cleaned before final assembly 02 Parts properly mounted to tunnel/motor foundation 03 Parts in good condition, no damage visible 04 Already equipped wiring properly installed in junction box For wiring and cabling instructions, please refer to the manual that came with the propulsion control system Mounting of the propeller prime mover Before mounting the propeller prime mover to the foundation, the coupling half must be mounted to the prime mover shaft. When the coupling half is delivered pre-machined, the shipyard must finish (machine) the bore according to the Wärtsilä drawing and/or the manual of the supplier of the prime mover. For mounting of the prime mover a set edge is provided in the foundation. This set edge has sufficient clearance to adjust the centre line of the prime mover to the centre line of the coupling half on the pinion shaft. The maximum permitted misalignment of the coupling is given in the applicable data-sheet. However, to minimize the radial and axial forces on the input shaft of the thruster as well as the drive shaft of the prime mover, the actual misalignment must be kept as small as possible.

58 6. Tunnel and Thruster 6.2 Instructions for disassembly In the following sections some special instructions are given for disassembly. Note that the gearing and the hub mechanism require great care and precision. Therefore only allow experienced craftsmen to perform repairs. We advise you to ask for a Wärtsilä engineer of our technical service department to assist in major repairs and surveys. You can also contact Wärtsilä Netherlands B.V. for more specifics regarding overhaul and/or service contracts Demount propeller blades When demounting blades, follow the rules listed below: Make sure hub rotation is controlled when one or more blades are demounted. Decide on the number of blades to be demounted. Carry out grinding or welding on locking strips in one action on all blades. Loosen or final tighten all blade bolts in one action on all blades. Lay down the blades on wooden pallets, to avoid fall over because of the centre of gravity of the blade. Oil will be spilled during demounting, and must be collected in catch tanks. References: Procedure Drawing: "Assembly of the hub" Chapter: "Hydraulic system" Paragraph: "Filling and draining of the hydraulic system" The blade s position is advised to be around zero propeller pitch, and in the 6 o'clock position. Check the position of the propeller blade, and readjust its position if necessary. Pay attention to the WARNINGS and CAUTIONS. 1 Shut down the transverse thruster and place warning signs. 2 By careful grinding, remove all blade bolt locking strips from all blades to be demounted. 3 Drain the hub cavity according the procedure in Chapter: "Hydraulic system" Paragraph: "Filling and draining of the hydraulic system". 4 Remove the locking strips (16) from the blade bolts. Loosen all blade bolts with the socket adapter and ring spanner. Alternative methods such as the use of a hydraulic torque device are also allowed. 6 When aft most blade bolts of one blade are loosened, loosen the foremost blade bolts of the opposite propeller blade before turning the propeller. This reduces the number of turnings. 7 Turn the propeller blade that is to be demounted into the 6 o'clock position, and make sure the propeller shaft cannot turn. 8 Loosen and remove the blade bolts with the socket adapter and ring spanner (see the chapter "Tunnel and Thruster"); watch the O-rings. It is advisable to renew the O-ring seal when replacing the blade. 9 Apply proper hoisting equipment (based on good craftsmanship and actual situation) on the blade. 10 Lower/lift the blade from the hub until the dowel is free. 11 Lay down the blades on wooden pallets, to avoid fall over because of the centre of gravity of the blade and secure them. 6-6 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

63 6. Tunnel and Thruster 6.3 Instructions for assembly Assembly is carried out in reverse order as described in section 6.2 Instructions for disassembly. For detailed mounting instructions, see section 6.1 Installation procedures. During assembly special care must be taken with regard to the following: All parts must be absolutely clean. All parts must be in perfect condition. All bolts must be tightened to the correct torque. (See assembly drawings and TDI sheet: "Torque manual symbols and values"). Make sure not to damage the seals when mounting the parts. 6.4 Cathodic protection of the transverse thruster To protect the submerged parts of the thruster and tunnel, cathodic protection is required. Usually, sacrificial anodes will not be positioned on the pod, but on the tunnel only. The tunnel will only be equipped with the first set of sacrificial anodes by Wärtsilä when ordered or mentioned in our scope of supply. More specific details regarding this cathodic protection can be found in the drawing "Arrangement of Transverse Thruster" / remark no. 2. The inside part of the tunnel is provided with anodes to protect the complete thruster for a specific period of time against galvanic corrosion, provided that the rest of the ship is sufficiently protected by a system fully compatible with the anodes used on the thruster. The drawing Anode Plan gives the following information: Number and used type of anodes. Mass of the anodes. Period of protection of the thruster. Material of the anodes. Position of the anodes. The anodes fixed to the tunnel are welded on double plates to simplify replacement without damaging the tunnel. 6. List of Drawings DAAF A Arrangement of Transverse Thruster...

Rev cyclo-palloid gears / 4 W MOUNTING GUIDELINES FOR CYCLO-PALLOID GEARS Fundamental rule: Contact pattern: Always mount the gears in such a way that the contact pattern is right, even if this causes the teeth ends not to be in line. The contact pattern must always be in the centre of the teeth. In off load condition the length of the contact pattern must be between 40% and 60% of the tooth length. The contact pattern should not touch the tooth tip or root; a free space should be visible between the contact pattern and the tooth tip and tooth root. Check both pinion and wheel! 1.1 Checking the contact pattern The contact pattern can be checked by smearing some bright coloured grease to the teeth. Then allow the gear to rotate a few times. Now the contact patterns will become visible. The photos show contact patterns on the teeth of a crown wheel. The photo on the left-hand side shows the convex flanks. The photo on the right-hand side shows the concave flanks. Both sets of contact patterns show that the gear set is in the correct position.

68 6. Tunnel and Thruster W C - Gearset adjustments Document title: Gear set adjustments Doc. no. W Rev. 02 Page 2 / Checking the torsional flank play (backlash) The backlash should be measured tangentially to the circumference of the crown wheel. Therefore, the pinion shaft must be locked. It should be made sure that backlash is always checked at several spots of the circumference of the crown wheel. If there is not sufficient backlash the oil film may be squeezed off. If there is too much backlash, the contact path is shortened and the rolling circles are no longer exactly generated. The optimum value depends on the module of the gears: Module Mn Backlash mm Module Mn Backlash mm Note: The gear set manufacturer inscribes the measurement of the gear backlash on the crown wheel. This occurs during production before the final stage of assembly W rev2.doc SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

69 6. Tunnel and Thruster W C - Gearset adjustments Document title: Gear set adjustments Doc. no. W Rev. 02 Page 3 / Controlling the contact pattern and backlash The contact pattern and backlash both are controlled by adjustment of the axial position of pinion and wheel. This position can be changed by correcting the thickness of the split type adjustment rings which determine the position of the axial bearings in the housing. The lengthwise position of the contact pattern on the teeth is for 80% controlled by the pinion. The position of the wheel has an influence of only 20%. The figure below defines a shift in position towards the centre of the axes as negative, a shift away from the centre as positive. The shift in contact pattern on tooth of the wheel is also shown. A negative movement (pinion shaft towards the centre) results in a shift of the contact pattern on the convex flank towards the outer diameter with a tendency towards the tooth root. This is the driven flank on a unit with only one direction of rotation. A positive movement (pinion shaft away from the centre) results in a shift of the contact pattern on the convex flank towards the inner diameter with a tendency towards the tooth tip. For the concave flank, the shift in lengthwise direction is opposite to the shift on the convex flank. He tendency towards the tooth root for a negative movement and towards the tooth tip for a positive movement is the same as on the convex flank. Of course, the shift of the contact pattern on the pinion teeth corresponds with that on the wheel teeth. This means that a shift towards the outer or inner diameter of the wheel is followed on the pinion. However a tendency towards the tooth root on the wheel means a tendency towards the tooth tip on the pinion and opposite. In the figure below, two wrong patterns with the respective corrective actions are shown. Wrong pattern Wrong pattern Corrective action Move the pinion shaft in positive direction, shift the pinion shaft away from the centre of the axes. Corrective action Move the pinion shaft in negative direction, shift pinion shaft towards the centre of the axes W rev2.doc 3 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

70 6. Tunnel and Thruster W C - Gearset adjustments Document title: Gear set adjustments Doc. no. W Rev. 02 Page 4 / 4 The backlash is for 80% controlled by the axial position of the wheel. The position of the pinion has an influence of only 20%. The backlash can be measured as described on sheet 2. When the backlash is not correct and the lengthwise position of the contact pattern is corrected by the axial position of the pinion, the contact patterns on convex and concave flanks both can be in the middle, but their position will be wrong height wise. The contact is completely at the tip or at the root of the teeth. The following figure gives the wrong position of the contact pattern in height after the lengthwise position was corrected by the pinion. The wheel position should be corrected as indicated below. Wrong pattern Wrong pattern Corrective action Too little backlash Move gearwheel in positive direction, shift gearwheel away from the centre of the axes.

81 7. Hydraulic System 7. Hydraulic System This system provides the required lubricating and/or hydraulic pressure for a smooth and reliable function of the transverse thruster. A malfunction of this system will have severe impact on the proper working of the complete transverse thruster installation. 7.1 Data and product descriptions Product description Lubrication/Pitch system (with header tank) General description and components The combined Lubrication and Pitch Set has two functions: It generates the hydraulic energy needed for pitch actuation. (if applicable) It circulates the oil for filtering The hydraulic power pack is equipped with: Table 7-1 Hydraulic Components Item Code Description Function Set points A M E-motor To drive the related hydraulic gear pump B M E-motor To drive the related hydraulic gear pump A Hydraulic gear pump To pressurize the hydraulic system B Hydraulic gear pump To pressurize the hydraulic system 101 Proportional valve Oil supply for the pitch rate A Filter unit To keep the hydraulic oil clean A Non return valve To block the oil flow from the related hydraulic gear pump B Non return valve To block the oil flow from the related hydraulic gear pump 038 Non return valve To keep the oil in the system 032 Shuttle valve To steer the oil flow to the pitch actuator for a more negative or positive pitch adjustment TT Temperature transmitter Detection of high oil temperature 6 C TI Temperature gauge To show the oil temperature A/B PT Pressure transmitter To detect low oil pressure from the related hydraulic gear pump 0. bar (1 x 100% only) 8 bar SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

The hydraulic pressure from the pump feeds through the proportional valve (101*) and then connects with the hydraulic oil supply unit on the free end of the propeller shaft Combined pitch and lubrication pump unit Lubrication function: The lubrication function is an integrated part of the pitch system, as the pitch systems uses the same oil as is used in the thruster for lubrication. The suction of the pump unit is connected to the thruster pod. This oil sucked up from the pod and is then pressurized by the pump(s) up to the required pressure. Then the oil passes through the oil filter to remove contaminants from the oil. This clean oil is ready to be used for pitching or can be directly returned back into the thruster pod. The pump unit also measures the oil temperature and the pressure drop over the filter. When the pressure drop over the filter becomes too high a clogged filter alarm will be generated by the control system. (See I/O-list for details) Pitch function: To create the correct hydraulic pressure the Load sense valve (126) is applied. This pressure regulating valve opens at a pressure of 10 bar. The load sense valve opening pressure will be increased linear with the required pressure for pitch actuating. This is done by selecting the highest oil pressure of the two pitch connections with the shuttle valve (032). The opening pressure of load sense valve (126) will be the current pitching pressure + 10 bar. At a pressure of 120 bar the safety valve (12) opens. When the pitch is stationary, proportional valve 101 stands in the middle position. The oil flow then passes through the filter and the load sense valve (126), back into the thruster pod. When pitch changing is required, proportional valve (101) is actuated. By actuating the proportional valve (101), the oil flow passes through into the selected pitch connection. This will activate the hydraulic cylinder that operates the pitch changing yoke. Returning oil from the hydraulic cylinder passes back through the proportional valve into manifold and flows back into the thruster pod. The pitch changing direction is controlled by the proportional valve. 7-2 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

83 7. Hydraulic System This valve is actuated by electronic remote control. In emergency situation, the valve also can be actuated manually. When the proportional valve is actuated while the propeller pitch is blocked by a foreign object or the cylinder yoke is at the mechanical limit of its stroke, the pressure increases until the pressure safety valve (12) opens at a safety pressure of 120 bar. The setting of this valve can only be checked and adjusted when the cylinder yoke of the hub is moved to the mechanical limit of its stroke. This can be done by actuating the directional valve manually by means of a pin or screwdriver. For more specific details regarding actual pitch adjustment, see "Oil distribution box and pitch adjustment". Pressure monitoring and alarm The pressure transmitter (474.01) and the pressure gauge (482.02) are connected to the pressure line in the manifold block. The pressure transmitter is adjusted to switch over when the pressure decreases below 0. bar. The transmitter is connected to the starting circuit of the prime mover through the remote control system. It is not possible to start the prime mover when hydraulic pressure is not available. The transmitter is also used for the alarm circuit. When the pump and the piping system are in good condition, the pressure transmitter signal switches over just after starting the pump unit. * See the drawing "Hydraulic Pump Unit" for details Filter system See the drawing: "Hydraulic Diagram" for details. The return oil from the hub is passed through the return oil filter (426.03). This filter has a bypass valve. The relative pressure over the filter is calculated from the absolute pressures on and , or, in case of 2*100% or 2*0% duty, the higher of the pressures on A or B is used in the calculation. If the filter cartridge is clogged, the gauge shows in the red area and the filter clogged signal is triggered. The hydraulic system must be stopped to exchange the filter cartridge. The leakage oil flow from the hub and the oil distribution unit coming either from the header tank or directly from the pod is passed through the oil filter. The tank can be filled through the connection on the manifold (FL). For cleaning and inspection purposes the complete cover together with all components can be removed after disengaging the pressure lines and wiring. The hydraulic pump unit is suitable for all recommended oil types (see the paragraph: "Recommended types of oil") at a minimal starting temperature of 0 C and a maximum environmental temperature of 40 C. The normal operating temperature will be between 40 C and 60 C. * See the drawing "Hydraulic Power Pack" for details Product description header tank Header tank and functional connections See the drawing: "TT Header Tank ** Litre Standard". The header tank is provided with: SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

84 7. Hydraulic System Equipment Low level switch Dip stick Filler/breather Symbol The oil pressure in the pod must be kept at a higher level than the static water pressure in order to prevent water ingress if the shaft seals get damaged. For this reason, the header tank must be placed at a height of approximately 1.2 X + metres above the centre line propeller (X = distance centre line propeller to loaded waterline). In order to protect the pinion shaft seal for oil pressure loads that are too high, the calculated height (1.2 X + ) must not exceed 1 metres. If it does, make sure to ask Wärtsilä Netherlands B.V. for advice. The "VT" line is connected to the top of the pod and acts only as venting connection. The "ST" line is connected to the bottom of the pod. It is advisable to install a shut-off valve between "ST" and the lubrication oil tank to enable draining of the pod without having to drain the lubrication oil tank as well. When such a valve is installed, it must be normally opened! NOTE For a safe operation of the system it is absolutely necessary that the valves have the correct position. Oil tank(s) and piping must be kept frost free. 7.2 Installation procedures Flushing of the hydraulic/lubricating system (CT) General information regarding flushing hydraulic and lubrication system Documents This section describes the installation and flushing the hydraulic and lubrication system. Before operating the hydraulic/lubricating system, all piping must be flushed to ensure that the power pack or luboil pump(s) operates in a clean system. A system that is not clean can cause failure of the pump(s) and the valves of the power pack. The components of the Wärtsilä delivery are already cleaned at the shop. When installing the hydraulic/lubricating piping, always make sure to work with cleaned pipes and couplings to prevent incorporation of dirt as much as possible. See WARNINGS, CAUTIONS and Instructions. Installation and assembly drawings Tools and equipment Flushing is done with a special flushing unit, the pump unit can not be used for flushing because the flow of this pump is much too small. 7-4 SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

86 7. Hydraulic System CAUTIONS Make sure that the pressure pumps cannot run simultaneously. The equipment is not designed for this purpose. Simultaneously running the two pumps can cause serious damage to equipment. It is essential that the hydraulic and lubrication systems be kept clean at all times, especially after any work involving (dis-)connection of pipe lines. When removing pipelines from their circuits, make sure that the ends are kept clean. Enclose the ends in clean materials to prevent the entrance of foreign particles. After abrasively cutting pipe lines, the cutting points must be thoroughly cleaned and the pipe lines flushed. See "Flushing pipe lines". If you have any doubts about the cleanliness of the pipe lines after repair work, thoroughly flush the hydraulic or lubrication system. Quality of replacement parts Use OEM replacement parts, for type, specifications and ordering notes. See the appendix "Assembly Drawings and Components". Quality of replacement piping The system operates with oil pressures up to 130 bar. It is therefore essential that any replacement of oil pipes must meet the equipment quality specifications. See the appendix "Datasheets, Drawings and Components" Flushing pipe lines Pay attention to the WARNINGS and CAUTIONS. Disconnect the pipes from the system components and fit temporary pipes in between, creating a closed loop with the flushing unit, and bypassing the system components. Pumps with sufficient flow will do the flushing. In most cases, the flow of the flushing pump is sufficient to give a flushing velocity of at least 7 m/s. When the prescribed pipe diameters are used (see the drawing: "Hydraulic Diagram"), the following flows are necessary, as shown in the table below. Pipe size [mm x mm] Min. pump flow dm 3 /min Pipe size [mm x mm] Min. pump flow dm 3 /min 28 x x x x x x x x x x In most cases, the following table can be used for transverse thrusters.

87 7. Hydraulic System 1 Use special flushing fluid with low viscosity (system oil can be used), heated up to 60 ºC. 2 Hammer the pipes to loosen dirt particles. 3 Change the flow direction a few times. 4 Check the filter regularly and replace the filter cartridge until the filter remains clean. Flushing duration must be at least 2. hours; after each hour, plan in a stop of minutes. 6 If possible, reverse the direction of the flow a few times. When the pipes are flushed properly, drain the fluid, blow out the remaining fluid with dry air, remove the temporary pipes, and reconnect the system components Flushing hydraulic systems The components of the Wärtsilä delivery have already been cleaned at the shop. When installing the hydraulic/lubricating piping, always make sure to work with cleaned pipes and couplings to prevent incorporation of dirt as much as possible. If the hydraulic systems must be flushed again, act as follows: Pay attention to the WARNINGS and CAUTIONS. 1 Fill the hydraulic system with system oil; see the paragraph "Recommended types of oil". 2 Check the pumps one by one to make sure they run in the same direction in which the arrow on the pump points. 3 Start flushing by running one pump. 4 Watch the level in the tank using the dipstick, and refill timely to keep the oil level far above the permitted minimum. The oil temperature must be approximately 60 ºC; if a heat exchanger is present, adjust the temperature of the water supply to 60 ºC. 6 Check the functionality of the heat exchanger by changing the water supply. 7 Check the filter regularly and replace the filter cartridge until the filter remains clean. 8 The header tank, if present, will automatically be filled slowly with the returned oil. The oil level in the tank will decrease and must be refilled. 9 Change the propeller pitch regularly from full forward to full astern and vice versa in order to de-aerate the hub cylinders and hub cavity. The oil level in the tank will decrease and must be refilled. Use the proportional valve of the hydraulic system for pitch changes. 10 Repeat pitch changing also during dock and sea trials to make sure that the propeller and shaft line are de-aerated. The oil level in the (power pack) tank will decrease and must be refilled Recommended types of oil (CT) The following types of oil can be used in the transverse thruster system. Depending on the area of operation, either viscosity class ISO VG100 or ISO VG10 must be used: For vessels operating worldwide, ISO VG100 must to be used. For vessels operating in (sub)tropical waters only, ISO VG10 is recommended. SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

When removing pipelines from their circuits, make sure that the ends are kept clean. Enclose the ends in clean materials to prevent the entrance of foreign particles. After abrasively cutting pipe lines, the cutting points must be thoroughly cleaned and the pipe lines flushed, see the instruction: "Flushing of hydraulic piping". If you have any doubts about the cleanliness of the pipe lines after installation or repair work, thoroughly flush the hydraulic system. Quality of replacement parts: Use OEM replacement parts, for type, specifications and ordering notes. Quality of replacement piping: The system operates with oil pressures up to 160 bar. It is therefore essential that any replacement of oil pipes must meet the equipment quality specifications. See the relevant datasheets, drawings and components. Filling of the hydraulic system See the drawing: "Hydraulic System" Inspect the inside of the header tank on cleanness before starting the filling operation. Always use clean oil (ISO4406, class 21/19/16 (equals approximately NAS1638, class 10)) and make sure that all material used for filling is cleaned before the filling takes place. For recommended types of oil see paragraph "Recommended types of oil". Note that the hydraulic system and the gearing can only be guaranteed if the right oil type is used. Make sure to ask for a confirmation if a different type of oil will be used. The system is filled through the filler/breather of the header tank (if installed) or with the hand pump (if available). The filling of the gear pod must be done slowly, thus preventing pressure building up in the pod, which can damage the shaft seals SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

91 7. Hydraulic System For venting during the filling procedure, loosen the plug on top of the pinion shaft sealing housing (3&4*). The safest way to check if the pod is filled up properly is to disconnect the "LL12.1" line at the header tank during filling and to see if oil is coming up in this line. When the pod is filled and vented, place the drain plug (44**) from the hub cavity (plug between the propeller blade feet) in the 12 o'clock position and screw it out to vent the hub. Fill the hydraulic system up to the L-Level of the tank. NOTE Do not fill the hydraulic system up to the H-Level. The remaining space is reserved for thermal expansion of the oil. Filling up to the H-level can result in an overflow. * See the drawing "Assembly of the Pod" for details ** See the drawing "Assembly of the Hub" for details After filling, check the oil level of the tank(s) often, as the gear pod vents slowly. Venting is done automatically by the "VT" line at the top of the pod if this line is installed with an upward slope from the gearpod to the tank. Draining If work must be done on hydraulic parts in the propeller shaft or hub: The header tank must be isolated by closing on the tank. The hub can be drained by using the bleed screws (44*) in the hub body. To avoid any oil spill, the connections PC1 and PC2 on the hydraulic pump unit must be loosened to create a vent opening. If oil must be replaced completely: The header tank must be drained by removing the plug. The hub can be drained by using the plugs (44**) in the hub body. To avoid any oil spill, the connections PC1 and PC2 on the hydraulic pump unit must be loosened to create a vent opening. The pod can be drained by using the plug (247*) in the pod body. * See the drawing "Assembly of the Pod" for details ** See the drawing "Assembly of the Hub" for details SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

Complete the oil sampling sheet, according to the approved laboratory. Include: Installation number MP/xxxxx Oil brand Date of extraction Operating hours since last oil change and last oil analysis Total operating hours 6 Send to Wärtsilä Propulsion Service Department, or approved laboratory. 7 Send results to Wärtsilä Propulsion Service Department. 8 Follow recommendations of the oil analysis report Functional test hydraulic system Reference drawings/documents: "Hydraulic Diagram". "Hydraulic Power Pack". Selection table "Hydraulic Components" Operational checks WARNING Before conducting this test, contact the captain first and ask for his approval (maximum speed 6 kph). CAUTION! It is strictly forbidden to run with two hydraulic pumps (only DP-class approved installations) simultaneously in order to reduce pitch adjusting time. The equipment was not designed for this, so running both pumps at the same time will lead to unacceptable damage SNL14042M1HH1P - Canadian Coast Guard - a2-7 April 2016

93 7. Hydraulic System Pitch adjusting time by local manual control With the hydraulic system in proper working order, the proportional valve (101) can be actuated on the solenoid. Put the propeller blades in the maximum ahead position (pump pressure at C1) by pushing the pinion of the valve to the left or right using a pin or small screwdriver or if applied with the ahead push-button of the proportional valve (101). Put the propeller blades in the maximum astern position (pump pressure at C2) by pushing the pinion of the valve to the left or right using a pin or small screwdriver or if applied with the astern head push-button of the proportional valve (101). Record time. Safety valve Put the propeller blades in one of the maximum positions (see "Pitch adjusting time by local manual control"). The safety valve PSV1 (12) is now set at the safety pressure; see selection table "Hydraulic Components. The safety pressure is the maximum necessary pressure with a margin of 1 bar. NOTE During the first trials of the ship, the required pressure can be somewhat higher because of "running in" phenomena. In order to keep full controllability, the safety pressure must be temporarily adjusted to a higher level. Make sure to check the maximum required pressure after some time and decrease the setting of the safety valve as much as possible. Check the pressure on the pressure gauge and correct if necessary by adjusting PSV1 (12). Switch-over system of the pumps (class approved DP systems only) Make sure that the local manual starters of the two pumps are set to 'AUTO'. On the Engine Control Room/Engine Room (ECR/ER) panel, select pump 1 as the main pump with the pump select knob. Stop the running of pump 1 by switching the local manual starter to 'OFF'. Check whether the low-pressure alarm is activated. Check whether the stand-by pump is automatically started. Now check the system the other way around by switching the local manual starters of the two pumps to 'AUTO' again and on the ECR/ER panel selecting pump 2 as the main pump. Stop the running of pump 2 by switching the local manual starter to 'OFF'. Check whether the low-pressure alarm is activated and the stand-by pump automatically started. Switch the starters of the two pumps to 'AUTO' again. 7.4 List of Drawings DAAK Block Diagram Hydraulic System... DAAK Hydraulic Diagram... DAAK Hydraulic Power Pack...

143 9. Prime Mover DAAF28314 A - Instruction Manual E-Motor MIB.ALG. 9 Pages / Page 2 1. GENERAL INFORMATION This manual concerns normal three phase induction motors with an output varying from small to middle size; they are externally cooled, totally enclosed, supplied in a cast iron or aluminium frame and provided with ball bearings or roller bearings, lubricated with grease. 2. DELIVERY After receipt, remove the package material, if any, and mind the parts that have been delivered loose. Check the motor to see whether transport damage has occurred. You should be able to rotate the shaft easily and smoothly by hand. Compare the details on the nameplate with those of the power network and with the requirements of the motor. 3. MOUNTING The motor must be fixed on a stable, clean and flat foundation with good fitting foundation bolts, using washers. Never mount a motor manufactured for a horizontal mounting on a surface with an angle of inclination of more than 1 degrees without consulting the supplier in advance. Foot & flange motors always have to be mounted in such a way that the drain holes, if any, are situated at the bottom, otherwise you risk that moisture will condensate in the motor and cannot be drained off. To this end you need to remove the drain plugs. Under no circumstances the entrance of cooling air, drafted by the cooling fan, may be obstructed. This will cause overheating of the motor. Special attention is required where motors will be located in small-enclosed rooms. The ambient cooling temperature must not exceed 40 ºC, unless otherwise agreed upon at the time of ordering. 4. COUPLING 4.1 Direct coupling The motor and driven shafts must be accurately aligned. In case of a flexible coupling, the manufacturers distance between the parts to be coupled must be adhered to, also the degree of misalignment must be within the makers tolerance. We do not recommend using solid couplings. ENG000110JDJ SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

144 9. Prime Mover DAAF28314 A - Instruction Manual E-Motor MIB.ALG. 9 Pages / Page Indirect coupling Flat or V Belts Mount the motor on slide rails in order to adjust belt tension. The belt pulley has to be fitted hard up the shoulder of the shaft. The pulley center line should be within the shaft center line. Use correctly sized belts with a correct profile and in sufficient numbers to drive without slip and undue tension. Align both pulleys accurately in such a way that the center of both pulleys are in line. A belt pulley, which is either too small or too wide, or too high, a tension on the belt may damage the bearing or cause a shaft break. In case of doubt, consult the supplier Spur Gear Drives The motor and the driven machine have to be positioned in such a way that the two gears align correctly. The motor should then be fixed with dowels Shaft couplings and pulleys etc. Remove the corrosion protection from the shaft extension and the coupling elements. The coupling parts, belt pulleys and gear wheels need to be dynamically balanced and fit easily on the shaft and to be provided with good fitting keyway. In the factory the rotor has already been dynamically balanced including a half key in the shaft. The dimension and the tolerances of the shaft extension and the key are indicated on the motor dimension sheet. Assembling the coupling elements has to been done with great care. Careless handling may damage the bearings, shaft or end shields. Do not file or emery on the shaft to achieve a fit! When fitting pulleys couplings or bearings, we recommend using heat elements; therefore the part to be mounted has to be heated till ± 100 ºC. A large washer and setscrew can be useful for pushing on pulleys using the tapped hole in the shaft. Only use proper tools for removing the above mentioned parts e.g. pulley drawers.

145 9. Prime Mover DAAF28314 A - Instruction Manual E-Motor MIB.ALG. 9 Pages / Page 4. ELECTRICAL CONNECTION.1. General information On delivery the motor will rotate clockwise looking at the drive when the phases L1, L2 and L3 are connected respectively to the connection terminals U1,V1 and W1. Exchanging any two-phase lines can change the direction of rotation. When a motor is only suited for one direction of rotation, it is indicated with an arrow on the motor fan cowl. Connecting cables must comply with the IEC regulations. Line fuses only protect the cables in case of short circuiting and do not constitute a safeguard against the overheating of the winding caused by overload. Therefore it is recommended that a motor start- and overload protection is mounted, giving single phase and overload protection..2. Circuit Normally our motors are provided with a terminal box with six connections, to which six leads from the winding are connected either in a delta connection or in a star connection by means of connection links. Usually two voltages are indicated on the rating plate of these motors, which mean that the motor can be connected to a circuit having one of these voltages. If the mains voltage is corresponding with the lowest indicated voltage, the winding has to be connected in delta connection (see figure 1); if it is corresponding with the highest indicated voltage, the winding has to be connected in star connection (see figure 2). A motor with e.g. 230/400V on its rating plate is suited to be switched on directly, on a circuit with a voltage of 230 V between phases with the winding connected in a delta connection, or on a circuit with a voltage of 400 V with the winding connected in a star connection.

146 9. Prime Mover DAAF28314 A - Instruction Manual E-Motor MIB.ALG. 9 Pages / Page If the motor is switched on with a star delta starter the motor is only suited for a main voltage on the rating-plate, this is the delta voltage. In this case, the connection strips on the terminal box have to be removed when the motor is connected. The star/delta connection will be made successively during the start up. If only one voltage is indicated on the nameplate together with the delta sign, the motor can be switched on directly at the indicated voltage or with a star/delta starter.

PUTTING INTO SERVICE Before putting a motor into service, one should check especially when the motor has not been used for a long time that the insulation resistance of the winding is sufficient. The insulation resistance has to be at least 100 MΩ on a 1000V megger. If the insulation resistance is not high enough, the motor has to be dried out revarnished or rewound. Check all connections and adjust the thermal protection units to the correct current. Switch the motor on in a no load state to determine the direction of rotation. Load the motor gradually and check whether it runs without vibration. The motor can be used under a variation of the main voltage ± % or frequency variation of max. ± 2% compared to the nominal frequency or nominal voltage, in compliance with the international regulations for electric machines. 7. MAINTENANCE 7.1. Dust The totally enclosed and fan cooled three phase squirrel cage induction motors require very little maintenance. Nevertheless it is recommended to check the motor regularly in order to prevent a breakdown caused by dust, moisture, vibrations, too much or too little greasing. The outer parts of the totally enclosed motors, especially the cooling ribs or cooling channels, have to be kept as clean as possible in order not to obstruct the cooling air from the fan extracting the heat from the motor frame Moisture Motors that are stalled for a long time, should be started from time to time to prevent moisture affecting the windings in the long term. Before putting the motor into service, one should check especially when the motor has not been used for a long time that the insulation resistance of the winding is sufficient Wear & vibration To prevent abnormal wear & vibration, one should: a. Take care that the tension of the belt or the chain is not too high; b. Check whether the mounting of directly coupled machines is correct; c. Check whether the foundation bolts to fasten the motor and the slide rails are tightly fixed. ENG000110JDJ SNL14042M1HH1P - Canadian Coast Guard - a2-7 April

148 9. Prime Mover DAAF28314 A - Instruction Manual E-Motor MIB.ALG. 9 Pages / Page Greasing Before the motor leaves the factory, the bearings are filled with a Chevron SRI 2 grease The sizes 6 up to and including 20 are provided with shielded/sealed bearings (ZZ), which have been filled with lifetime grease by the manufacture of the bearings. Motors with sealed bearings and no re-lubrication system require no maintenance other than checking for noise & temperature during their lifetime. Sizes 280 up to and including 60, has been provided with a permanent lubrication system containing a grease valve. The lubrication must take place when the machine is running. The old grease is ejected from the grease valve thus maintaining the correct level and avoiding overfilling which would be harmful. 7.. Replacement of ball or roller-bearings When a bearing has to be replaced, the old bearing has to be removed from the shaft with proper tools in order not to damage the shaft. Thereupon the bearing location on the shaft has to be cleaned and checked thoroughly. To fit a new bearing correctly, heat to 100 ºC with an electric induction heater, then slip quickly onto the shaft up to the stop. In the case of a roller bearing only fit the inner part of this bearing with the induction heater. Do not mount the end shield until the bearing has cooled down. 8 Bearing type.

149 9. Prime Mover DAAF28314 A - Instruction Manual E-Motor MIB.ALG. 9 Pages / Page 8 9 Grease-interval Bearings By the term greasing interval we mean the number of working hours after which the bearing lubricant has to be replaced. Under normal load and environmental conditions the quality of the grease ensures proper operation of the motor for about service hours with 2-pole design and service hours with multi pole design. If not otherwise agreed upon the grease need not be refilled during this period. Nevertheless the condition of the grease filling should be occasionally checked also within the said lubricating intervals. The stated service hours are only current under operation with rated speed. For relubrication thoroughly clean the bearings with a suitable solvent and use the same or substitute grades specified by the motor manufacturer. Bear in mind, however, that the bearings should be filled only up to about 2/3 of their free space as a complete filling of the bearings and bearing covers results in an increased bearing temperature and therefore in increased wear. For bearings with relubricating facility regrease at the grease fitting with the motor running according to the grease amount required for the motor in case. The relubrication intervals should be looked up in the following table: A chemically aggressive environment, extreme moistness, strong vibrations, high or low ambient temperatures are not normal circumstances and such conditions must be taken into account.
