8 AXIAL FANS & VANEAXIAL FANS TYPE MPV APPLICATIONS The Nyborg axial fans are heavy duty fans designed for marine applications. The fans are delivered in sizes from ø25 to ø16 with capacities up to 2. m3/h and static pressures up to 16 Pa. EXECUTION The MPV fans are heavy duty fans designed for marine applications, manufactured in mild steel, hot dip galvanized. OPTIONAL EXECUTION Fan in stainless steel execution (aisi34/316) Fan in alum execution, IMPELLER: The MPV fans are made in two versions with two different impellers: MPV-A1 with A impeller for fan without guide vanes A simple and robust design often makes this the most cost effective alternative. The impeller is made of sea water resistant alum and is cast id one unit and has a high reversible capacity (approx 6% of normal capacity). The model is most suitable for high air volumes and low to medium/moderate pressures. The fan with the A impeller also have a small stall area. For sizes from ø25 up to ø5mm the fan can be delivered with an impeller made of reinforced polypropylene. with variable pitch. MPV D1 With D impeller for fan with guide vanes: The axial fans with the D impeller is equipped with guide vanes for higher pressures and efficiency. The impeller is made of sea water resistant alum and has variable pitch to easier suit different capacities and pressures. Due to the guide vanes the fan can achieve pressures up to 16 Pa. CASING The MPV fan is made in four models MPV A1K/D1K tube fan for installing in duct or end of duct, with inspection cover and cable glands in casing MPV A1E/D1E for duct connection / duct end installation. The fan is with short casing and inlet cone for better performance. The motor is outside of the casing for easy accessability. As standard a protection grid is fitted to the fan. MPV A1B for wall mounting The fan is with inlet cone for smaller pressure drop and better performance and is delivered with a protection grid (wire guard) as standard. MPV A1M/D1M for installing in duct or duct end. The fan is a swing out construction where motor and impeller can be swung out for maintenance (and inspection). N-623 SYKKYLVEN, NORWAY TEL FAX

81 CENTRIFUGAL FANS TYPE LSV/MSV/HSV APPLICATIONS The centrifugal fans LSV, MSV and HSV are designed for marine use. The fans can be used for both as supply and exhaust fans. Typical applications for low and medium pressure fans are galley fans, mess room, sanitary spaces, dayroom, technical rooms etc. Often it can be used as a central with a plenum suction chamber for multiple duct connections. High pressure fans are often used for gas freeing for LPG tankers, chemical tankers etc. DESIGN The MSV / LSV / HSV fans are single inlet centrifugal fans with direct drive as standard. The design is based on three main groups, low, medium and high pressure. LSV - Low pressure: pressures up to 4Pa, capacities up to 12.m 3 /h with duct connection ø25 to ø12mm. MSV - Medium pressures up to 8.Pa, capacities up to 95. m 3 /h with duct connection ø125 to ø9mm. HSV - High pressure up to 3. Pa. capacities up to 45. m 3 /h with duct connection ø6 to ø5mm. EXECUTION The fan housings and impeller are as standard manufactured in sea water resistant aluminium and painted. This gives a corrosion resistant fan and a spark proof design. N-623 SYKKYLVEN, NORWAY TEL FAX OPTIONAL EXECUTION Fan housing and impeller in aisi316l execution. Steel - galvanized or galvanized and painted execution are delivered on request. IMPELLERS: The impeller is as standard delivered in the same material as the fan housing, as standard salt- and ammonia resistant aluminium, dynamically balanced. The impellers are divided into four main groups: B - type: The standard impeller for the centrifugal fans. This is a cost effective impeller with high efficiency. Z type: Self cleaning impeller, ideal for applications where dust or material in the air stream can build up on the impeller and cause imbalance. F type: Forward curved blades (sciroccio impeller) for applications where high air flow are required. This impeller is only delivered for the smaller centrifugal fans. R type: heavy duty impeller with radial blades for transport applications (e.g. saw dust for wood industry or similar). ELECTRIC MOTOR The motors are as standard TEFC squirrel caged inductive electric motors in marine execution. Motors are IP55 and insulation class F as standard. The fans can also be equipped with EX motors for hazardous applications. Motor options: IP56, IP65 or IP66, anti condensing heating element offshore painting Vibration monitoring

260 MIST ELIMINATOR LOUVER with filter (prefabricated modules) DRS-FiMO-F & DRS-FiMi-F BxH General The DRS-F w filter is a two stage intake louver with a mist eliminator louver in front followed by a filter as the 2 nd stage. The filter section is made up by prefabricated modules in standard sizes. The filter prevents soot, dust, sand, insects or salt etc from being sucked into the ventilation system and the rooms to be ventilated. Applications: Used for air intake where removal of soot, sand, dust, moisture, insects etc from the air stream is desired. Typically used for engine room intake, accommodation, but can also be used as pre-filter, e.g. for turbo intake. Models DRS-FiMO-F with hinged louver for access to filter from front (outside). DRS-FiMi-F with access to filter from inside (back side of louver). Design and drain The louver has vertical profiles with grooves/water traps where the water is led down and drained out to the front (outside) at the bottom of the louver. The louver is only made in certain step sizes due to using prefabricated standard filter modules. Standard filters from most filter manufacturers can be used. For the DRSFaF-F, there is one detachable bar, giving an opening of min 56x9 (WxH) if access to inside is needed. Execution: the louver and the filter frame are made in sea water resistant aluminium. The frames for the prefabricated filter usually are made of plastic. Special execution: Louver and filter frame in stainless steel. Mist eliminator louver in alum and frame in stainless steel. Cut out: W cut out = W louver +2, H cut out = H louver +2. Max radius on the cut out is 35mm. For a bigger radius the cut out can be increased to +4mm. Special design. Louver and filter section for mounting completely on outside on bulkhead (e.g. if limited space behind louver/filter). With access to filter from the side (through inspection hatch). Filter/Performance Filter can be delivered in EU 3, 4, 5, 6 and 7 class. The prefabricated modules gives a high effective filter area, superior filtration, lower pressure drop and long time between filter change compared to plan filters (Filter) Maintenance When filter has reached recommended pressure drop it should be cleaned or changed. Time between change of filter will depend of environment for ship operation. A quick locking system makes filter changes quick and simple. Options: Louver equipped with pressure meter for indication of time for filter change. Drainpipe, either to outside or inside. wire guard for louver on inside (or outside), 12x12x1 stainless steel.

275 Document NYP155B Issued Revision PROCEDURE FOR INSTALLATION AND MAINTENANCE OF NYBORG FANS, CENTRIFUGAL AND AXIAL. 1 Purpose The purpose of this procedure is to ensure that all delivered fans are mounted, installed and maintained carefully by the purchaser. 2 Limited Applications This procedure comprise NYBORG Fans, both Axial and Centrifugal, Belt and Direct driven. If any special requirements are available beyond this procedure, a procedure adjusted to the conditions will be issued. 3 Responsibility Manufacturing manager is responsible that this procedure is part of each fan delivery. Any competent person in purchaser s organization is responsible for all activities that this procedure describes. 4 Description 4.1 Installation/Mounting First of all, check the fan regarding to transport damages. Any damages must be reported immediately. It is strictly prohibited to lift the fan by the shaft, the bearings or the impeller. A good result can only be obtained by using correct foundation for the fan. The foundation has to be almost straight and made in a heavy duty design. It is important that the fan is not tightened up awry by the foundation bolts. Adjust with shims if it necessary before tighten up the foundation bolts. Concerning duct-top mounted axial fans, check that the top flange is straight. If the fan is equipped with adjustable vibration isolators, these have to be adjusted until the fan is level. Then tighten the locknuts. If the fan is equipped with flexible connections, like PVC-coated canvas collar or similar, these have to be mounted in such a position that the flexible conn. don t tighten at any place around the fan inlet or outlet.

276 Document NYP155B Issued Revision Commissioning Check all bolts for foundation, el.motor, and fixing bolt for impeller that they are tightened up before starting. Rotate the impeller by hand for examining that the impeller is running easily. Start the fan and stop immediately after. Check that direction of rotation agrees with indicating arrow on the fan housing. Start the fan once again, and let it run for appr. 1 hour. If any abnormal noise/conditions occur, stop the fan immediately and find the causes. After running for appr. 1 hour, stop the fan. Check once more that all bolts mentioned above are tightened up. Equal check must be carried out after 1 week operation. After this, the fan has to be checked at regular intervals (periodic), and the following points are highlighted: Out of balance/vibrations on fan caused by dirt/sediments on fan impeller. Heat generation in fan/motor. El.motor. Independent section Fan Bearings. Independent section. V-Belt Transmission. Independent section. 4.3 El.motors El.Motors are usually equipped with ball bearings sealed for life. Lifetime is appr. 2. operating hours. After this time bearings ought to be changed.

277 Document NYP155B Issued Revision Fan Bearings On V-Belt driven NYBORG fans, following main bearing designs are used. - Ball Bearings, sealed and lubricated for life. These demand no maintenance at all, only a minimum of supervision. - Grease-filled Spherical Roller- and Ball Bearings. Grease filled bearings have to be cleaned up and refilled with grease (lubrication) at regular intervals. Enclosed you will find an alignment chart. This alignment chart indicates the lubrication intervals in operating hours. Actual parameters in the alignment chart are fan speed (n/rpm) and shaft diameter (ø d). Grease-filled bearings must not be supplied with more grease than half-filled. An increase outwards this, may cause heat generation. The lubrication intervals in the alignment chart are only guiding values. Local conditions as moisture, dust and extreme temperatures will make shorter lubrication intervals necessary. See also bearing manufacturer s own lubrication instructions. 4.5 V-Belt Transmission The alignment of the V-belt transmission has to be checked by the help of a straight edge ruler. The V-belt tension must be exact adjusted for obtaining as long lifetime as possible on the V-belts as well as the bearings. As a principal rule, a V-belt is correct straightened up when the V-belt can be forced together with a distance like the width of the V-belt by normal finger pressure. By high power ratings, an indicator for V-belt tension ought to be used. The fan bearings are designed for normal V-belt transmission. If the V-belt tension is too high, unnecessary wear and tear of fan bearings as well as motor can occur. Shidding during starting is normal by power ratings higher than 15 kw. After appr. 1 week operation/running, the V-belt transmission has to be checked, and if necessary to be adjusted/straightened up. Later to be checked up at regular intervals (periodic supervision). 4.6 Spare Parts All fans manufactured by the NYBORG A/S company, are equipped with a manufacturing signboard (tag plate), which indicates serial no (L.No.), model, performance etc. By ordering spare parts, signboard data always must be specified.

304 Dust Ignition protection in hazardous areas Combustible dusts is hazardous as it can form potentially explosive atmospheres when dispersed in the air. Furthermore, layers of combustible dust may ignite and act as ignition source for an explosive atmosphere. Hazardous areas with dust can be found in a variety of industries such as: - agriculture - chemicals - plastics - stock holding Selection and installation of electrical equipment To ensure equipment can be safely used in hazardous areas with dust, the following procedure should be considered before selecting a product: 1. Type of dust: - Will a cloud of dust be present around the product or - will a layer of dust build up on the product and if so, what will be the maximum thickness of the layer between two cleaning/maintenance periods? 2. Characteristics of the dust: - Is the dust electrically conductive or nonconductive? 3.

305 General about hazardous areas Standards Motors for hazardous areas comply with the following international standards: IEC publications 679- (2-6) and (21-2); (1999-6) European standards (latest edition) EN 514, EN 516, EN 518, EN 519, EN 521 and EN British standards BS 5 Part 16 Preamble In hazardous areas, it is the utmost importance to ensure the safe use of electrical apparatus. To this end, many countries have regulations concerning both the design and use of such apparatus. These regulations are becoming increasingly harmonized within the framework of IEC recommendations and European Standards. The hazard may be due to an explosive atmosphere composed of a mixture of gas, vapors or dusts with air. This chapter only deals with safety in explosive gas atmospheres for which European Standards exist. Flameproof enclosure EEx d and EEx de The motor enclosure shall be designed in such a way that no internal explosion can be transmitted to the explosive atmosphere surrounding the motor. The enclosure must withstand, without damage, any pressure levels caused by an internal explosion. The shape, length and gap of part assembly joints, at shaft opening, cable entries, etc., shall be designed to allow for throttling and cooling of hot gases escaping outside. The standards emphasize the impact of an explosive atmosphere (for instance, explosion pressure) over constructional requirements of such apparatus. Work on assembly devices of enclosure component parts is only permitted using prescribed tools. Cable entries must meet the requirements of this type of protection. The temperature of the motor's external enclosure should not exceed the self-ignition temperature of the explosive atmosphere of the installation area during normal Alleinschutz thermistors as sole protection (optional) The flameproof motors from ABB, frame sizes 8 to 4, have been certified for thermistors as sole protection against overload. This construction, "Alleinschutz", is available as an option, see variant codes. "Alleinschutz is a term that defines the certification of flameproof motor and protection device together. The certificate confirms that thermistors and relays will switch off the motor in case of overheating before the temperature of the motor's external enclosure exceeds the temperature marking stamped on the rating plate. Each motor ordered with thermistors as sole protection operation. For this reason, rated output depends on this rated maximum temperature for the considered area. No motor device outside the flameproof enclosure (e.g., ventilation) shall be a potential source of sparks, arcs or dangerous overheating. Variants combining two types of protection usually combine d and e protection. The most commonly used and recognized by the CENELEC European Standards is the EEx de variant. The motor is designed with an EEx d flameproof enclosure, while the terminal box features an EEx e increased safety protection. Such design combines the superior safety degree of the d type of protection with the less stringent electrical connection requirements of increased safety motors. Motors featuring dual protection are seldom encountered - such as an increased safety motor with a flameproof enclosure designated EEx e + EEx d in European Standards. will be tested, with locked rotor, up to the point where the thermistors trigger the relay to turn off the motor. At the triggering temperature, the motor has to be within the certified temperature class. The relay is included in the certificate, which means that only approved relays can be used for "Alleinschutz. Please note that sizes 315 to 4 require special technical solutions, consult ABB. 8 ABB / LV Motors / Cat. BA/Ex-motors GB 4-22

306 Increased safety design, EEx e The design of this motor type prevents the occurrence of sparks, arcs or hot spots in service (including starting and locked rotor situation), that could reach the selfignition temperature of the surrounding, potentially explosive atmosphere, in all inner and outer parts of the machine. This is ensured by applying constructional or dimensional provisions that mainly concern: specified minimum values for creepage distances and clearances use of tracking-proof isolating materials suppression of sharp angles where static electrical loads could build-up ensuring electrical and mechanical assemblies are tightly secured minimum backlash values between stationary and rotating parts (e.g., air gap, ventilation, etc.) temperature-rise limits, taking into account locked rotor, normal operation, accidental mechanical stalling of machine under the most adverse thermal conditions, i.e. when thermal equilibrium of machine is reached while in service. Temperature rise limits are to be considered for two operating aspects; one for normal operating conditions and the other under accidental stalling conditions. Temperature rise limits under normal operating conditions The expected electrical lifespan of a motor depends on its temperature rise for a given insulation class, and on the motor winding temperature, in operation, which is not homogeneous with hot spots appearing. For these reasons, a safety margin of 1 K is allowed for between windings temperature rise at rated output, as measured by the change of resistance method, and the maximum temperature rise permitted by the winding insulation class. Temperature rise limits during short circuit under accidental stalling conditions Should the machine stall while in operation, a shortcircuit current nearly equal to the starting current will develop, and stator and rotor winding temperatures will rise rapidly (see figure 1). To prevent this temperature value from exceeding the temperature level below which the apparatus should not cause the spontaneous ignition of an explosive atmosphere, protection devices must trip within a specified time (t E ). This tripping time depends on the short-circuit current level or the short-circuit current to rated current ratio (I A /I N ). Figures 2 and 3 show, for commonly used protection devices, the limiting ratio between short-circuit current inrush I A /I N and rotor stalling time t E, according to the EN and VIK. This type of protection is inappropriate for commutator machines or brake-motors which, by principle, are capable of producing arcs, sparks or hot spots.

307 Non-sparking design, EEx na, Ex na, Ex N This type of protection is allowed to be used in the hazardous area corresponding to zone 2. This design is also known as 'Non-sparking' type as the motor must be designed in such a way that no sparks can occur in normal operation, and used within the ratings specified by the manufacturer, which excludes thermal requirements due to starting or accidental stalling. Yet, EHRS's (Essential Health and Safety Requirements) stated in ATEX Directive for products installed in zone 2 have introduced new requirements on the motor design compared to previous technical report IEC (1987) used for Zone 2. These new requirements make the motor safer against the risk of spark during the start-up. However, along with the ATEX -directive, the national standards will be withdrawn and supersided by the ATEX directive 94/9/EC and the EN standards. Thus the new British standard for non-sparking is BS-EN 521. EEx na motors are not flameproof motors. They have no flamepath, and thus the enclosure groups A, B and C have no relevance. The letter "A" stands for nonsparking equipment according to EN 521. After 1 st of July, 23 it will not be allowed to put on the market any motor according to IEC in hazardous area corresponding to zone 2 in Europe. The requirements of IEC are identical to the requirements of EN 521, which proves that although CENELEC and IEC operate at two different levels, their action has a strong mutual impact in the electrotechnical field around the world. Dual certification EEx na motors in cast iron frame can also be used for Dust -applications. Following combinations are possible: CI sizes EEx na II T3 for zone 2 DIP T125 C, IP55 for zone 22 These features are possible due to the IP protection. The gases penetrate this protection, and thus the inside surface temperature class is T3 (2 C). The ingress of dust, however, is prevented and the dust determines the outside surface temperature class: T 125 C.

309 Electric motors ELECTRIC MOTORS Information on safety and commissioning for low voltage Information on safety and commissioning for low voltage asynchronous motors In accordance with L.V. directive 73/23/EEC 1 General Information Electric motors have dangerous voltage carrying and rotating components as well as surfaces that may become hot. All work involved in the transport, connection, commissioning and regular maintenance must be carried out by qualified, responsible specialists (note VDE 15; IEC 364). improper behaviour may result in serious injury and damage to property. The applicable national, local and works regulations and requirements must be complied with. 2 Intended use These motors are intended for commercial installations. They comply with the harmonized standards of the EN634 (VDE 53) series. Utilization in areas subject to explosion hazard is not permitted, unless expressly Intended for this purpose (see additional notes). In certain special cases, for example. on use in noncommercial installations, it requirements are more strict (e.g. protection against contact with children s fingers), is it the responsibility of the customer to ensure compliance on installing the equipment. The motors are rated for ambient temperatures of -2 o C to +4 o C and site altitudes <1m above sea level. Any contradictory information. on the rating plate must be observed. The conditions on site must correspond to all rating plate specifications. Low voltage motors are components for installation in machinery in terms of the Machine directive 89/392/EEC, Commissioning must not take place until it has been proved that the end product conforms with this guideline (please note EN 624-1). 3 Transport and storage Any damage detected after dispatch should be reported immediately to the transport company and commissioning must be postponed. Tighten the eyebolts. They are designed for the weight of the motor only therefore do not attach any additional loads. If necessary, use suitable, adequately dimensioned transporting equipment (e.g. rope guides). Remove existing shipping braces before commissioning; and reuse for subsequent transport. If motors are stored, a dry, dust-free and low vibration (Vrms <.2 mm/s) environment is important (to avoid bearing standstill damage). On long-term storage, the regrease interval of the bearings is reduced. Before commissioning, measure the impedance of the insulation. It values <1kW per volt of rated voltage are measured; the windings must he dried out. When motors with roller bearings for increased cantilever force are operated the, value of cantilever force must be minimal 3% of permissible cantilever force (see catalogue). Operating with smaller cent lever force Is the cause of bearing faults. 4 Installation Ensure an even underlying surface, good foot or flange fixing and precise alignment for direct coupling. It is important to ensure that the mounting conditions do not cause resonance with the rotational frequency and the doubled supply frequency. Turn the rotor by hand and listen for any unusual grinding noises. Check the direction of rotation in the decoupled state (note section 5). Only mount or remove drive components (belt pulley, coupling, etc.) using suitable tools (heat up), and cover to shield against contact. Avoid unpermissible belt tensions (see catalogue and technical data). The balancing type is specified on the shaft end face or rating plate (H =half- and F= full-key balancing). On mounting the drive, note the balancing type! In the case of half key balancing, the protruding, visible part of the half - featherkey must be removed. 1

310 ELECTRIC MOTORS Information on safety and commissioning for low voltage A canopy is recommended for designs with the shaft end pointing downwards, and with the shaft end pointing upwards a cover must be provided by the customer to prevent foreign bodies from falling into the fan. Do net obstruct ventilation! Discharged air, also from neighbouring equipment, must not be sucked In again immediately. Checking of bearing grease must he carry out when motors are longer than 12 months storage. When storage conditions are the cause of grease depreciation (presence of condensate, consistency change) the grease must be exhanged. Grease exhange must be carry out no later than in three year interval. 5 Electrical connection Work is only permitted to be carried out by qualified specialists on the stationary motor, while disconnected and prevented from being switched on again. This also applies for the auxiliary power circuits (e.g. Anti-condensation heaters). Check that the equipment is potential-free! If the tolerance limits are exceeded that are specified in EN 634, part 1 / IEC 34-1 (voltage ± 5%, frequency ± 2%, shape of curve, symmetry) the heating effect is increased and the electromagnetic compatibility is affected. Please note the specifications on the rating plate and the connection diagram in the terminal box. Connections must be made in such a way as to ensure that a permanently safe electrical connection is maintained (no protruding wire ends) use the corresponding cable end pieces. Create a safe earth continuity connectien. Tightening torques for terminal board connections. M4 M5 M6 M8 M1 M12 M16 Tightening torque (Nm),8...1,2 1,8...2,5 2, , Clearances in air between bare live parts themselves and between bare live parts and earth must be > 5,5 mm {U rated < 69 V) - If must be ensured that the terminal box does not contain foreign bodies, dirt or humidity. Seal any unused cable entry openings against dust and water. Secure the featherkey on test operation without drive components. For motors with brakes, check that the brakes are operating perfectly before commissioning. 25mm 2 1mm 2 25mm 2 1mm 2 25mm 2 If connections are made with DIN cable lugs, band the cable lugs downwards. Connecting a single conductor with a terminal clip. Connecting two conductors of almost equal thickness with a terminal clip. If connections are made with DIN cable lugs, under the outer earthing angle. If connections are made with DIN cable lugs. 6 Operation Vibration levels of V rms <3,5mm/s{P N 15 kw) or V rms < 4,5mm/s (P N >15 kw} are quite acceptable in the. coupled state. If deviations from normal operation occur - e.g. increased temperatures, noises, vibration - the motor should be switched off in the event of doubt. Determine the causes and contact the manufacturer if necessary. Do not disconnect protective equipment, even under test operation. Under dirty operating conditions, clean the air channels regularly. Open any closed condensate water holes from time to time! 2

311 ELECTRIC MOTORS Information on safety and commissioning for low voltage For motors without regreasing facilities, bearing or grease replacement must be carried out in accordance with the manufacturer s instructions, or after 3 years, whichever is sooner. Bearings with regreasing facilities must be regreased when the motor is running. Please note the greasing plate! In the case of motors with separate ventilation, the separately-driven fan must be switched on throughout motor operation. 3

320 INTRODUCTION The electrical machines referred to in these instructions are intended as components for use in industrial areas. The information contained in this documentation is designed for use by qualified personnel who are familiar with the current rules and regulation in force. They are not intended to replace any installation regulations issued for safety purposes. NOTE REGARDING ELECTRO-MAGNETIC COMPATIBILITY Low voltage induction motors, if installed correctly and connected to the power supply, respect all immunity and emission limits as set out in the regulations relating to electromagnetic compatibility (EMC Generic Standard for industrial environments). In the case of supply by means of electronic impulse (inverters, soft starters etc.), all verifications and any modifications, necessary to ensure that emission and immunity limits, as stated within the regulations, are respected, are the responsibility of the installer.. GENERAL SAFETY WARNINGS DANGER Rotating electric machines are dangerous. Consequently: - improper use - removal of protection and disconnection of protection devices - lack of inspection and maintenance can cause serious harm. The personnel must be informed of any danger caused by contact with: - live parts - rotating parts - hot surfaces. In normal working conditions the motor exceeds 5 C. The safety manager must ensure and guarantee that: - the machine is moved, installed, put in service inspected, maintained and repaired only by qualified personnel, who should have: - specific technical training and experience - knowledge of technical standards and applicable laws - knowledge of general safety regulations as well as national, local and installation regulations - ability to recognize and avoid all possible dangers. Work on the electric machine should be carried out upon authorization of the safety manager after having ensured that: a) the motor has been disconnected from the power supply and that no parts of the motor including auxiliary parts are live b) discharge of the condenser has been done for single phase motors c) the motor is completely stopped and there is no danger of accidental restarting d) the right precautions against faulty braking operations have been taken for self-braking motors where thermal protection with automatic reset is used care must be taken to ensure automatic restart cannot occur. Since the electric machine referred to is intended to be used in industrial areas, additional protective measures must be taken and guaranteed by the person who is in charge of installation where more stringent protective measures are needed. 1. STORAGE AND INSTALLATION 1.1 Control 1.2 Storage procedure The motors are shipped ready for installation. Upon receipt remove packaging and turn the shaft to check the motor has not been damaged, also check all physical aspects of the machine for damage. In the case where the machine is damaged an immediale notification must be given in writing by the storeman and the representative of the carrier to CEMP INTERNA- TIONAL within 3 days If the motors are not used immediately, they should be stored in a clean, dry and temperate environment free of vibrations and protected from the weather. (If stored below -15 C, and before starting, the motor temperature must be restored to the permissable working temperature range (i.e. -15 C 4 C). In this case, it is necessary to specify these particular storage conditions during the ordering stage so that proper precautions can be taken during building and packaging When the motors are stored properly, bearings do not need maintenance. However, it is a good idea to turn the shaft by hand every three months. After storage for over one year motors with unshielded bearings (usually such motors have a lubricator and bear a lubrication plate), it is advisable to check the condition of the lubrication and motor components. 3

321 1.2.3 Before installation check the motor windings using the appropriate instruments to ensure the condition of the insulation between phases and between phase and earth are of the corrects resistance values. Do not touch the terminals during and immediately after measuring as they are live. If the insulation resistance value is less than 1 megaohm, or after storage in a damp environment, the motors must be put to dry in an oven for about 8 hours by gradually bringing the temperature up to 1 C. To ensure that the dampness has been completely expelled, the motors must be disassembled All operations listed above must be carried out by qualified personnel. In case of flameproof motors it is necessary: - to be very careful that the flame-proof characteristics are not altered - to have the procedure described in point carried out by authorized repair shops - to understand dismantling or opening of the motor during the warranty period without authorization of CEMP INTERNATIONAL may invalidate the warranty. 1.3 Installation Work on the electric machine must be carried out when the machine has stopped and been disconnected from the power supply (including auxiliary parts, such as anticondensation heaters) Lifting Before using the lifting rings make sure they have been tightened. The lifting rings are big enough to bear the weight of a single motor, therefore they must not be used to lift the equipment connected to the motor. In environments where the temperature is below -2 C, these lifting rings should be used with caution as they could break at low temperatures and cause damage Fitting devices to shaft Fitting if pulley, coupling or gear to the motor shaft must be carried out with care to ensure no damage is caused to the bearing. Remove the protective paint finish from the shaft and smear with oil then fit the device heating before fitting if possible to ensure an easy fit. Any component that is assembled on the motor shaft must be accurately balanced. Connection with fitments not balanced properly causes anomalous vibrations during operation that jeopodises proper working of the motor and drastically reduces its life Direct connection Use couplings that have been made and balanced perfectly align the motor shaft and the operating machine precisely. Inaccurate alignment may cause vibrations and damage to the bearings or breakage of the shaft end Connection by means of pulley Check that alignment with the pulley of the operating machine has been carried out perfectly. The tension of the belts must be enough to avoid slipping. Excessive tension of the belts causes harmful radial loads on the motor shaft and bearings, reducing their life. It is advisable to assemble the motor on beltstretching slides in order to regulate tension of the belts exactly. Connection with belts must be such as to avoid accumulation of static charges in the moving belts which could cause sparks Connection to power supply Use cables with sufficient section to bear the maximum current absorbed by the motor, avoiding overheating and/or drops in voltage. Connect the cables to terminals by following the instructions on the plate or on the diagram included in the terminal box. Check that terminal nuts are tightened. Connections to the terminals must be made in order to guarantee safe distances between live uncovered parts. Do the earthing by using the screw located inside the terminal box. Flame-proof motors are provided with a second earth stud located on the motor casing outside the terminal box. Earths must of sufficient size and installed according to relevant standards. The area of contact of connections must be cleaned and protected against corrosion. When the cable inlet is made by means of a cable gland, it must be chosen properly in relation to the type of plant and type of cable used. The cable gland must be tightened so that the retaining rings create the pressure necessary to: a) prevent transmission of mechanical stress to the motor terminals b) to ensure the mechanical (IP degree) protection of the terminal box. For flame-proof motors the cable inlet must be made by complying with the regulations in points 12.1 and 12.2 of the standard EN Apertures not used must be closed in accordance with specifications in point 12.5 of the same standard. When reassembling the terminal cover, make sure that if there is a seal, it is in the right place. Flame-proof motors do not have a seal so before reassembling the terminal box it is necessary to replace the layer of grease. The terminal box cover must be tightened to ensure it is properly sealed Connection of auxiliary parts (Table B) a) thermal protection Check which type of protection is installed before making connections. If thermistors (PTC) are used, it is necessary to utilize a suitable relay. b) anti-condensation heaters If the motor is fitted with anti-condensation heaters, their power supply must be separated from that of the motor, using the terminals housed in the terminal box. WARNING: the supply of the heater is always monophase and the voltage is different from that of the motor. Check that it corresponds to the one indicated on the plate. c) auxiliary ventilation Connect the supply of the auxiliary ventilation motor separately from that of the main motor. WARNING: use a device that allows starting and operation of the main motor only when the auxiliary fan is working. d) all the above-mentioned operations must be carried out by following the instructions shown on the diagrams of connection provided with the motor. 4

322 2. PUTTING INTO OPERATION It is the responsibility of the installer to establish the motor's fitness to be used in a certain plant, after analysing the characteristics of danger existing in the installation area with respect to current provisions of the law and to those issued for safety purposes. 2.1 Initial Controls Before starting the motor it is important to check that: a) installation has been carried out properly b) the bearings have not been damaged during installation c) the motor base is sturdy enough and the foundation bolts have been tightened d) the design data corresponds to those given on the plate and in the technical documentation The electric motor is a component made to be mechanically connected to another machine (single or part of a plant). Consequently, it is the responsibility of the person who looks after installation to guarantee that during operation there is an adequate degree of protection for people or things against the danger of accidental contact with moving parts. 2.2 Control of Design Data Make sure that the motor is suited for use in the working conditions foreseen and check the following: Environmental conditions a) environmental temperature: standard motors may work between -15 C and +4 C b) altitude: normal motors have been designed to work between and 1. m above sea level c) protection against the presence of harmful agents like: sand, corrosive substances, dust and/or fibre, water, mechanical stress and vibrations d) mechanical protection: installation inside or outside considering the harmful effects of the weather, the combined effect of temperature and humidity and the formation of condensation e) adequate space around the motor particularly on the fan side to allow proper ventilation f) motors mounted in the vertical, shaft down require a protective cowl over the fan inlet g) any danger of explosion or fire Working conditions a - operation type: the motors are normally for S1 type continuous operation b - load type: carefully evaluate machines with high moments of inertia and the relative starting times c - for motors intended for operation in hazardous areas (EEx-d or EEx-e) the motor type and temperature classification must comply with the area rating When there is an X on the plate near the certificate number, it is necessary to check on the certificate which additional conditions are required for proper working. d - for self-braking motors see the special applications envisaged in the relative catalogue Electric characteristics a - voltage and frequency should correspond to those on the plate b - motor power should be adequate as required by the load c - power supply protections against overloads and/or short circuits should be adequate for nominal currents and starting currents d - for connection to control circuits follow the connection diagram supplied with motor (Table A) Abnormal working conditions must always be defined when placing order to ensure that the site conditions are not prejudicial to the proper operation of the machine 2.3 Starting Before starting the motor ensure that the incoming supply cables are connected correctly For motors with forced ventilation by means of external ventilation make sure that the motor starter is interlocked with the, contactor of the external ventilator to ensure the fan is operational When all previous checks have been made satisfactorily, the motor may be started. Unless oterwise started all motors can be direct on line started. Save when otherwise indicated, all motors are fit for direct starting. If you intend to start the motor by means of static starters, rheostats or the star-delta system, they must be chosen and set property to avoid incorrect functioning of the motor. 2.4 Conditions of Use Once the motor has started it is necessary to check that during operations the working conditions remain within the limits envisaged, and that the following does not occur: a) overloading b) dangerous rise in environmental temperature c) excessive drop in voltage E very time there is a change in the working conditions, it is necessary to check that the complete fitness of the motor has been maintained for the new operating conditions. For example: - variation in working cycle - the function of the motor has not altered - moving of the motor to a different environment (from outside to inside) - moving of the motor from a low temperature environment to one with a higher temperature Before starting the motor after a long resting period, repeat the controls described in section 1. When supplied, heater must not be energised when the motor is running The motor must be used solely for applications it was designed for and must be utilized and controlled complying with the precautionary standards. If the machine shows anomalous working characteristics (greater absorption, increase in temperature, noisiness, vibrations), inform the personnel in charge of maintenance immediately. 5

323 3. MAINTENANCE Any operation on the motor must be carried out with the machine stopped and disconnected from the power supply (including auxiliary circuits, especially the anticondensation heaters). Maintenance of the original characteristics of electric machines over time must be ensured by a schedule of inspection, maintenance and setting up managed by qualified technicians. The type and frequency of maintenance depends on environmental and working conditions. For flame-proof motors, apart from specifications in this document, refer to the CEMP INTERNATIONAL manual entitled MAIN- TENANCE AND REPAIR GUIDE FOR ELEC- TRIC FLAME-PROOF MOTORS. As a rule, it is recommended that the first inspection is made after about 5 hours of operations (or, within 1 year), while subsequent inspections should follow the schedules established for lubrication and general inspection. 3.1 Inspection Check that the motor works normally without anomalous noise or vibrations. If it does not, locate the cause of the anomaly Make sure that the ventilation is not obstructed. Clean the motor by removing any dust or fibre deposits from the fins and from the fan cover Check that the supply cable does not show signs of wear and that the connections are tight. Make sure that the earth and supply cables are not damaged Check that the transmission elements are in perfect condition and that the screws and nuts are tight When the motor is installed in a very damp environment or is subject to drips of water, check regularly that the seal and retaining rings and any protective devices work efficiently. Ensure that there are no infiltrations inside the casing or terminal box The motors furnished with drainage devices should be checked and cleaned regularly so that such devices continue to work properly Make sure that thermal protections have not cut out and have been set properly. The right selection and setting of thermal protections for EEx-e motors is essential to guarantee the temperature class and safety against the danger of explosion Check that no modifications have been made that alter the electric and mechanical operation of the motor When the motor is installed in an environment where there are corrosive agents it is recommended to paint the motor itself to protect the outer surfaces from corrosion if necessary Every irregularity or anomaly found during inspection must be fixed immediately. 3.2 Lubrication Motors with shielded or sealed bearings (type ZZ or 2RS) do not require lubrication. Therefore, if used properly, they do not require maintenance Motors with unshielded bearings are furnished with lubricators. The interval of time between lubrications depends on the type of grease, environmental temperature, overheating of the motor and type of operation the motor carries out. The table C shows the intervals foreseen for 7 C as a working temperature of the bearings in normal operating conditions. It is recommended to use a good quality lithium based grease with great penetration capacity and high dropping point like Athesia 3 by IP, Beacon 3 by Esso or Avana 3 by Shell. If the velocity is different from the one given in the table, the intervals must be modified in inverse proportion. Eg. bearing 6314 at 1.8 RPM 15 1 = x 355 h = 295 h 18 Regardless of working hours, the grease must be renewed after 1 or 2 years or during a complete overhaul. When the motor is furnished with a lubrication plate, refer to the dates shown on it. 3.3 Disassembly and Reassembling the Motor All operations must be carried out bearing in mind health and safety regulations Before working on the motor it is advisable to consult the relevant catalogue and have all the tools ready Before proceeding with the disassembly the motor must be disconnected from the power supply. Make sure that the power is off and disconnect supply cables and auxiliary cables when there are any In order to work on the motor satisfactorily it should be removed from its mounting and placed on a work bench Take off the fan cover by removing the fixing screws. Using an extractor remove the cooling fan. Remove the end shields and withdraw the rotor being careful not to damage the windings. Precautions must be taken with flameproof motors so that the spigots on the frame and the end shields are not damaged. When the motor is disassembled and before it is reassembled it is necessary to protect the various components (particularly the bearings and windings) to avoid damage caused by dust or knocks For disassembly of self-braking motors follow the instructions shown in the relative catalogue. 3.4 Replacing the Bearings Remove the bearings using an extractor. Ensure the respective housings have not been damaged then fit the new bearings - these must be the same type as the old ones To fit the new bearings it is advisable to use a press and a sleeve which rests on the inner ring and must not put pressure on the outside ring of the bearing. The surfaces of the relative housings should be oiled slightly If the facilities are available, however, it is recommended that the bearings are heated to 9-1 C and fitted quickly to the shaft. Use a brass sleeve resting on the internal ring of the bearing and if a press is not available use a mallet After the assembly has been finished the internal rings of the bearings must rest against the relative shaft shoulders Before reassembling, clean the internal parts of the motor carefully and check that the components have not been damaged. Renew the layer of grease where needed on the abutting spigots and proceed with the reassembling. For more detailed information on the proper procedure, consult the catalogues relative to the various types of motors. 3.5 Overhauls and Repairs When needed, all motor components should be replaced by original spare parts. To request spare parts use the nomenclature shown in the catalogues and always give: - motor type - serial number - year built Overhauls and repairs must be carried out by trained personnel who guarantee restoration of the motor to its original conditions, we recommend that you contact an authorised repair agent. For further information please contact our sales department. 6

380 Reference project: Deepsea Rig Deepsea RIG Nyborg AS has participated in delivering HVAC equipment to the following project, including Cooling fans for Drawworks and ventilation of drillers cabin, listed below also similar project of equal deliverance of different owners. Deepsea Atlantic and Deepsea Stavanger. The two units are scheduled for delivery from Daewoo Shipbuilding and Marine Engineering (DSME) in South Korea early 29 and 2 quarter 21 respectively. The first unit - Deepsea Atlantic has signed a long term contract with StatoilHydro in Norway. The second unit Deepsea Stavanger is currently being marketed World Wide. Green Rig Deepsea Atlantic / Stavanger is designed for environmental sensitive areas, and the utmost focus has been put on zero discharge, low emissions and electrical solutions to reduce onboard oil volumes and associated pollution risks. Separate drain systems are installed for the machinery area, drilling area and all outside clean deck areas. No drain water is discharged without passing a cleaning system which ensures acceptable oil content. Important installations and arrangements to obtain the green rig are: Enclosed derrick which prevents mud spill to sea. All drain lines routed to central cleaning unit by use of several tanks and pumps. Discharge from mud pits by pumping, no gravity discharge. Waste management system implemented Low emission of NOX, clean design engines.
