Environmental care Wärtsilä s solutions are customized to specific ship design and operational requirements to ensure maximum efficiency, reliability and environmental performance over the entire lifecycle of the installation. Examples of Wärtsilä s recent achievements in environmental care are RT-flex engines, dual-fuel engines for LNG carriers and environmentally friendly stern tube sealing systems. IMO NO X regulation The Annex VI of the MARPOL 73/78 convention enters into force on 19 May 2005. All Wärtsilä and Sulzer diesel engines included in this booklet comply with the speed-dependent NO X limit. Environmental concepts for two-stroke engines RT-flex Sulzer RT-flex engines offer distinct benefits to shipowners. A clearly visible benefit is smokeless operation at all ship speeds. Reduced running costs of Sulzer RT-flex engines derive from reduced maintenance requirements and lower part-load fuel consumption. Precise control of injection, high injection pressures at low speed, and the sequential shut-off of injectors gives steady running at very low running speeds without smoking, down to 10-12% of nominal speed. Particular attention has been given to making the RT-flex system reliable. The common-rail concept also has inherent redundancy, adding to reliability and safety. SCR SCR (Selective Catalytic Reduction) can reduce NO X emissions by 85-95%. EnviroEngine for four-stroke engines Common rail Common-rail fuel injection technology keeps the fuel injection pressure high and constant over the entire load range, thus enabling operation without visible smoke over the whole operation field. Superior operation is demonstrated at all speeds and loads. The design of the common-rail system is optimized for new engines but it can also be retrofitted to existing engines. 7

Compressor Water injection Saturated air 70...90 C CASS The newest NO X reduction technology developed by Wärtsilä is called CASS Combustion Air Saturation System. The principle of CASS technology is to introduce pressurized water into the combustion process to reduce NO X formation. The pressurized water is added to the intake air after the turbocharger. The water evaporates immediately, due to the high temperature of the compressed air, and enters the cylinders as steam, thus lowering the combustion temperatures and the formation of NO X. The NO X reduction is up to 50%, and the water consumption is about two times the fuel oil consumption. DWI DWI (Direct Water Injection) can reduce NO X emissions by 50%. In this system, water is injected under high pressure directly into the engine cylinders. SCR SCR (Selective Catalytic Reduction) can reduce NO X emissions by 85-95%. Gas engines with superior environmental performance Gas engines have low exhaust gas emissions due to the clean burning properties of natural gas and the high efficiency of the Wärtsilä gas engines. The low carbon content in the natural gas also results in lower CO 2 emissions. 8

Propulsion and seals The Efficiency Rudder Vessels can be supplied with an Efficiency Rudder to increase propulsion efficiency and improve steering characteristics. The Efficiency Rudder features a fixed bulb attached to the rudder horn immediately behind the propeller. The rudder blade can be equipped with a flap at its trailing edge to increase the lift generated by the rudder. The bulb is removable to facilitate withdrawal of the tail shaft. The HR nozzle The HR (high efficiency) nozzle differs from the conventional nozzle through a special rounded leading edge and S-shaped outer surface. After introduction with small propellers (less than 3.5 m diameter) several hundred have since been applied to a wide variety of vessels. Full-scale tests on several vessels indicate an improved bollard pull in the order of 7-10%. This means an improvement of up to 13% in free-running conditions compared to a conventional nozzle. CoastGuard and Airguard EnviroSeal Any oil loss to the environment from a ship's stern shaft sealing system is unacceptable. Wärtsilä's EnviroSeals offer pollution-free sealing systems with a proven track record on all types of vessels. The EnviroSeals are equally suited to retrofitting into existing standard seal installations or, as is now common, to be specified by owners for newbuildings. The CoastGuard system is unique in that it enables all potentially polluting oil to be contained within the vessel using a double barrier, low-pressure void space. The Airguard system, with its air-induced controlled pressure components, ensures the seal is a truly anti-pollution lip seal. These sealing systems are now used on cruise ships, LNG carriers, containers, bulk carriers and many other vessel types to prevent both the leakage of bearing oil into the seaway and the ingress of water into the bearing system. They ensure continuous operation between planned maintenance periods, with no unplanned dry-dockings for emergency repairs. 9

Sulzer RT-flex engines Sulzer RT-flex engines are based on the RTA-series but have electronically-controlled common-rail systems for fuel injection and valve actuation. As well as the proven benefits of the RTA engines, the RT-flex engines have the additional benefits of: Smokeless operation at all running speeds Better fuel economy in the part-load range Reduced maintenance requirements, with simpler engine setting and extendable times between overhauls Lower steady running speeds 11

Definitions and notes Definitions and notes for two-stroke engines Dimensions and weights All dimensions are in millimetres and are not binding. The engine weight is net in metric tonnes (t), without oil and water, and is not binding. Fuel consumption All brake specific fuel consumptions (BSFC) are quoted for fuel of lower calorific value 42.7 MJ/kg (10 200 kcal/kg), and for ISO standard reference conditions (ISO 15550 and 3046). The BSFC figures are given with a tolerance of +5%. Sulzer RT-flex engines have a lower part-load fuel consumption than the corresponding Sulzer RTA engines. The values of power in kilowatts and fuel consumption in g/kwh are the standard figures, and discrepancies occur between these and the corresponding brake horsepower (bhp) values owing to the rounding of numbers. For definitive values, please contact our local offices. ISO standard reference conditions Total barometric pressure at R1 1.0 bar Suction air temperature 25 C Relative humidity 30% Charge air or scavenge air cooling water temperature: - with sea water 25 C - with fresh water 29 C Rating points for Sulzer engines The engine layout fields for Sulzer low-speed diesel engines are defined by the power/speed rating points R1, R2, R3 and R4 (see diagram right). R1 is the nominal maximum continuous rating (MCR). Any power and speed within the respective engine layout field may be selected as the Contract-MCR (CMCR) point for an engine. 24

Cylinder lubrication The guide feed rate for cylinder lubricating oil is 1.1 g/kwh for Sulzer RTA and RT-flex engines built to the current design standard. This applies for engine loads in the range of 50 to 100% and for all fuel sulphur contents from 1.5% upwards. A still lower guide rate of 0.9 g/kwh or less can be used after analysis of engine performance by a Wärtsilä service engineer. For further information please consult your nearest Wärtsilä company. The low cylinder oil feed rates are made possible by the excellent and very stable piston-running behaviour routinely obtained by Sulzer low-speed engines built to today s standard designs. Not only are cylinder wear rates low (typically less than 0.04 mm/1000 hours) but also the TBO (time between overhauls) is meeting today s requirement. These good results are being achieved by the well-established Sulzer load-dependent accumulator cylinder lubricating system. It has been standard in Sulzer low-speed engines since the late 1970s, and has been further developed over the years with the application of electronic control. Load-dependent control ensures that the specific feed rate (g/kwh) remains virtually constant with reference to the actual operating load. For further information on this subject, please contact the local Wärtsilä companies. 25

Power range for four-stroke engines 5000 10000 15000 20000 25000 safe operation. The innovative multi-fuel technology allows flexibility to choose between gas or liquid fuel. When necessary, the engines are capable of switching from one fuel to the other without interruption on the power generation. Propac The comprehensive product portfolio places Wärtsilä in a unique position to offer a tailored and complete propulsion solution for practically any mechanical propulsion application. In-house design, manufacturing and project management ensure matching components and total responsibility, without forgetting lifetime support for the complete system from a single contact. In order to reduce implementation time and costs Wärtsilä has developed a range of pre-engineered propulsion packages named Propac for two selected application types. Propac CP: four-stroke medium-speed engine, controllable pitch propeller, reduction gear with built-in clutch, shaft, seals, bearings and an integrated control system. Propac ST: four-stroke medium-speed engine, steerable thruster with either fixed pitch or controllable pitch propeller, clutch, shafting, bearings and an integrated control system. 27

Generating sets A wide range of generating sets, comprising generator and diesel engine mounted on a common baseframe, are available for both service power generation and for diesel-electric propulsion. All generating sets listed in this section are based on medium-speed diesel engines designed for operating on heavy fuel oil. Generating sets with dual-fuel engines are presented separately under dual-fuel engines. The generating sets are resiliently mounted and the generator voltage can be selected in all cases except for the Auxpac generating sets, which are Low Voltage only. Larger diesel generators are delivered for separate mounting of the diesel engine and generator. Auxpac The Auxpac generating sets are available in a selected range as pre-engineered and pre-commissioned auxiliary generating sets. The common baseframe is optimized for the package, which together with the compact design of the engine and the selected generator, offers unmatched power-to-space and power-to-weight ratio. Other benefits of pre-engineering include readily available documentation, also including models in Tribon format, and short lead-times. Auxpac generating sets are offered only as 400V/690V - 50Hz and 450V/690V - 60 Hz in the power range 500 kw to 2800 kw. 46

Auxiliary systems All auxiliary equipment needed for the diesel engines can be delivered by Wärtsilä. Some equipment can be built on the engine, and the rest can be delivered loose or grouped in modules. Depending on the engine type and application, lubricating oil pump, HT- and LT-cooling water pumps, fuel pump, oil filters and coolers, pre-lubricating oil pump and thermostatic valves can be built on the engine. Stand by pumps, seawater pumps, central coolers, starting air vessels, lubricating oil automatic filters, exhaust gas silencers and boilers are typically delivered for separate mounting. Standardized modular auxiliary units are available for several systems, such as fuel booster modules, fuel-separating modules, lubricating oil separating modules, cooling water preheating modules and starting air compressor modules. Tailor made modular auxiliary units are available on request. Maximum compatibility is ensured when auxiliary systems are delivered together with main propulsion engines and diesel generator sets. Whenever necessary, the auxiliary systems are tailored to optimize the operating performance for a specific trade. The systems are specified to minimise building costs and operating costs for a specific combination of main and auxiliary engines. Fuel booster unit 54

Fixed pitch propellers Each ship s hull has its own characteristics. In order to achieve the highest possible total efficiency of the vessel, the propeller must be a perfect match with the engine and the hull. A fixed pitch propeller is the choice when optimum efficiency, reliability and robustness are required. Fixed pitch propellers are usually applied for ocean sailing vessels, for example Container vessels Tankers Bulk carriers Dry cargo vessels Lips FP propellers for all shiptypes guarantee maximum efficiency and minimum noise and vibration levels due to tailor-made designs with the latest available technology. 58

Two Lips FP-propellers in HR nozzles. Nozzles The application of a nozzle increases the thrust at relatively low ship speeds. Significant savings can be achieved in terms of fuel consumption, depending on the number of revolutions and the capacity of the motor. The improved high efficiency nozzle, type HR, combined with a Lips propeller, can produce over 10% more thrust than conventional nozzles, both in bollard pull as in free sailing condition. The nozzle profile offers double profiled cross section (outside and innerside). This sophisticated shape improves the water flow both into and out of the nozzle, increasing thrust performance. 62

Efficiency Rudder Efficiency Rudder is an integrated concept that reduces fuel consumption, vibration and noise level compared to traditional design. At high vessel speeds and high power the risk of cavitation erosion is also reduced. In general a noise reduction of 3 to 6 db is expected. Single screw vessels: Controllable pitch propellers: Fuel saving of minimum 5%. Fixed pitch propellers: Fuel saving of minimum 3%. 30-45% reduction of propeller induced vibration level. Twin screw vessels: Fuel saving of 2 to 6%. Efficiency gain increase with increasing hub ratio, i.e. propeller hub/ propeller diameter ratio. About 25% reduction of propeller induced vibration level. 63

Propulsion solutions with waterjets Waterjets propulsion is the most successful and efficient method of propulsion for high-speed applications. The advantages are not only higher efficiency, but also lower vessel resistance due to the absence of underwater appendages like shafts, rudders and shaftstruts. The absence of any parts below the waterline also makes waterjets an ideal solution for shallow water operation. The unique design features of the Lips jet will ensure access to even the smallest ports. Hybrid propulsion systems the use of two fixed or controllable pitch propellers in combination with a centre waterjet combine the best of both worlds. The propellers are used for normal cruising while the combination of the propellers with the centre waterjet is used to achieve the top speed. Hybrid systems allow optimization of the propellers for the normal cruising condition, resulting in improved efficiency, low noise and vibrations and a smaller propeller diameter. 70

For instance a ship with four 4000 kw engines and a corresponding design speed of 35 knots will need four LJ91E jets. A ship with three 9000 kw engines and 37 knots will need three LJ135E jets. The correct jet size is thus indicated by the line above the intersection of the power and the design speed (see examples in above graphs). The above size range is not complete but represents the most often-used waterjet sizes up to 50 knots. We are available from the earliest design stages of the vessel to work with you on an optimized propulsion system. Please contact us for an accurate jet selection based on the specific vessel design parameters, or for details of waterjets for speeds above 50 knots and 40,000 kw.

Reduction gears The core function of a reduction gearbox is to reduce the main engine speed to the optimum propeller speed. The Wärtsilä gears have been designed to meet the highest standards of operational efficiency, reliability and low noise and vibration. Gear configurations The gears can be supplied with built in multidisc clutches. Single input, single output gears are available with vertical or horizontal offsets of the shafts. Twin input single output gears can be delivered with up to 3.8 m horizontal offsets. Power take-off arrangements More than 90% of all gearbox deliveries include a built-in Power Take-Off (PTO) for shaft generators. The standardized solutions are primary driven, which means that the PTO is running also when the propeller has been disconnected. Customized solutions like secondary driven-, twin- and two-speed PTOs are also available. Auxiliary propulsion drive for increased safety The basic idea of the Auxiliary Propulsion Drive (APD) is to be able to utilise the power from the auxiliary engines for propulsion as back up for the main engine. To facilitate the APD option a standard gearbox with a multidisc clutch is supplied with an additional Wärtsilä reduction gears Output range 142 128 116 110 105 95 85 75 68 62 56 50 46 42 38 76 Single reduction gears vertical offset SCV Single reduction gears vertical offset SV, SCV Single reduction gears horizontal offset SH, SCH

disconnecting coupling between the gear and the main engine. The APD may also be used for operation modes with low vessel speeds. Integrated or separate hydraulic system for gear and CP propeller Most of the Wärtsilä gears are purposely designed with an integrated hydraulic system for both the gear and the CP propeller. This will reduce installation cost for the yard and operational costs for the owner, as the complete hydraulic power unit for the CP propeller will be left out. For safety reasons the gear mechanically drives the main pump for the propeller. All gears can also be interfaced to a separate hydraulic power unit.

Propulsion control systems Optimised control of the propulsion machinery The Lipstronic 7000 propulsion control system is computer based, designed to monitor and control all components in a modern propulsion system with high accuracy, tailored to the individual applications. Remote control for controllable pitch propellers: Lipstronic 7000 propulsion control systems is designed to optimise the control of any propulsion machinery. The system exists in two versions, the basic and the advanced. The Lipstronic 7000 basic is a cost effective standardised system to meet most of the demands in the market for propulsion control. This system is applicable for single engine configurations (including twin screw). The Lipstronic 7000 advanced introduces a modular designed system with communication on a two-wire field bus. This gives high flexibility and multi functionality. This system is applicable to as well for single as for twin engines configurations. Both systems are based on Programmable Logic Control (PLC) technology with high accuracy and tailored to the individual 80

applications. The system controls the propeller pitch position and engine speed either combined or in split modes. Included is a propeller- and engine load control system developed on the basis of research and experience over many years. A large amount of special functions to optimise ship operations are available. A user-friendly operator panel is delivered. This gives information of the propulsion plant and is used for calibration of the system. Up to 31 extra panels can be supplied as options. 81

Special functions as: Pitch reduction zone reduces propeller wear Fuel measurement program Windmilling prevention PTI/PTO functions Multiple combinator modes Frequency variation mode Cruise control Fine tuning pitch Electric shaft levers Engine start/stop and safety system (Some functions not available in the Basic) Controls Cost effective universal controls for any propulsion system Robust design with type approval Joy-stick available for small and large vessels Field bus application available Remote control for jets: These systems are similar to the one used for controllable pitch propellers, except an integrated joystick system which is an option for catamarans and monohulls. For monohulls, in case of joystick control, also a bow thruster is required. The joystick is a single lever manoeuvring enhancing system. Remote control for azimuthing thrusters: For vessels such as harbour tugs an integrated control concept similar as for jets is available. For large off-shore platforms, individual controls for propulsion and steering are available. This includes standardised interfaces with third party DP-systems. Co-ordinating control systems: The Lips-stick concept is a co-ordinating control system for offshore supply vessels, cable-layers and other ships which require manoeuvring enhancing systems. For vessels equipped with podded propulsors a dedicated Lips-stick is available, including features such as a simplex DP-mode and anchoring mode. 82

Seals Wärtsilä is the world s leading supplier of marine engineered sealing systems, and the only supplier in the world to offer a full range of both radial and axial seal types, commonly known as face seals and lip seals, for any ship type or ship size, whether naval or commercial. The products are reliable, efficient and easy to maintain through the global Wärtsilä service network. The range of seals is unequalled in the market.

CoastGuard EnviroSeal The CoastGuard sterntube sealing system has proved its worth as a reliable pollution free system. It is ideally suited either for retrofitting to existing vessels or for use on new tonnage, in particular for cruise vessels, tankers, bulk carriers, offshore vessels and RoRo s. Thanks to its unique design, the CoastGuard system eliminates oil loss from the outboard seal, even if it is fouled or badly damaged. It is also less susceptible to wear MC type CoastGuard seal and tear and ageing than conventional seals. In the outboard seal assembly, water is excluded by a radial face seal, which surrounds and encloses an oil sealing unit comprising a single elastomeric lip seal. This lip seal bears on a chromium steel liner which rotates with the shaft. A second lip seal, positioned forward of the oil seal, acts as a back-up seal if excessive water should enter the drain space. This drain space not only allows any oil or water passing to freely drain inboard, but also forms a coffer AC type CoastGuard seal dam between the seawater and the oil. 84 SafeGuard SafeGuard The SafeGuard seal is an anti-pollution sealing system. The aft seal is of a four ring type incorporating two water exclusion rings and two opposed lips, separated by a vented and drained void space. The void space is fitted with a drain line to enable the condition of the aft seal to be continuously monitored. The outer housings for the two water exclusion rings are fully split, enabling lip seal replacement without the need to remove the propeller.

AIRGUARD 3AS The AIRGUARD 3AS anti-pollution sterntube seal is a follow-up to the successful STERNGUARD seal assemblies. The aft seal is a built-up version of the MKII type of seal assemblies with a regulated air barrier chamber, and includes an Unnet system. The Unnet protects the seal from fishing lines. The use of air prevents the spilling of lubrication oil from the seal and water ingress into the seal system. AIRGUARD 3AS SANDGUARD 3AS-D The SANDGUARD 3AS-D is an improved version of the AIRGUARD 3AS seal and is specifically designed for use on Dredgers. Dredging vessels create and operate in a muddy and sandy environment which normally causes severe wear to the rubber sealing rings in the sterntube seals. SANDGUARD prevents both lubricating oil leakage outboard and seawater ingress inboard by supplying an outflow of air and freshwater, and consequently minimizes the wear to the rubber sealing rings.

ManeSafe Bulkhead Seals ManeSafe bulkhead seals ensure the integrity of watertight bulkheads where penetrated by the main and auxiliary propulsion shafts. The seal is bi-directional and can be fitted on whichever side of the bulkhead is more convenient. ND type bulkhead seal ManeGuard FSE The ManeGuard FSE is a face type seal for high performance applications in a fully split design with an elastomeric body and silicon carbide interfaces. The FSE is particularly suitable for high speed vessels, offshore ManeGuard FSE supply vessels, and other high powered vessels, such as tugs and trawlers. The FSE accepts misalignment, vibrations and large axial movements. For applications with open sterntubes the inboard seal has an emergency seal for safety, survey and maintenance purposes. The ManeGuard FSE can be fitted and serviced without removing the shaft, thus reducing the installation time to a minimum. 86 ManeGuard FSE

STAND-BY SEAL 4BL The STAND-BY SEAL 4BL is developed from the MKII seals. It incorporates an extra (standby) seal ring, which can easily be activated by closing two valves in the engine room. Under normal circumstances the standby ring is kept practically load-free, so no wear will occur. In case of an emergency, the seal ring is activated to perform as a normal oil side seal. STERNGUARD MKII (M) STERNGUARD MKII (M) The STERNGUARD MKII (M) type sterntube seal is a lip type seal using NBR ( #380) or Viton seal rings (all sizes). Both types are highly resistant to wear and to attack by seawater and oil. STERNGUARD MKII (M) seals are easily monitored. They can be inspected in situ and renewed without disconnecting the tailshaft assembly even without docking, provided that the vessel can be trimmed sufficiently. Unnet aft seal protection system This simple and highly effective system prevents lines or ropes from reaching the seals by the forward sliding face of the fin on a P-Ring which is pressed against the liner. The forward sliding face of the P-Ring, which is pressed against the inside cover, also provides double security. The Unnet is available as a complete system and available for lip type seals: MKII, 4BL, SafeGuard and 3AS (standard). Net Cutters are available for mounting between the rope guard and the propeller boss for all seal types.

ManeSeal The ManeSeal consists of two large assemblies. One fitted to and rotating with the propeller or shaft and one stationary. The stationary main seal unit is attached to the sterntube by means of a mounting ring and a flexible bellows assembly. This allows the seal to accept normal ship and machinery movements whilst ensuring sustained and MD type sterntube seal uniform face contact between the sealing elements. The design of the ManeSeal seal facilitates complete inspection of the seal face without the need to disturb either the propeller or the shaft. ManeBar ManeBar seals are designed for rugged, reliable service in small to medium sized vessels such as trawlers, coasters, tugs and offshore supply vessels. These extremely durable seals completely overcome the limitations of packing and stuffing boxes which are associated with worn shafts or shaft liners, leaking gland plates and continuous maintenance. Design simplicity provides maximum sealing with leakage virtually eliminated. ManeBar seals accommodate large axial, radial and angular shaft movements. 88 EL type ManeBar seal

ManeCraft The ManeCraft propeller shaft seal is designed specifically to meet the demanding requirements of today s pleasure and commercial craft. Easy to install, they replace old style propeller packed glands. Unlike a conventional packed gland the ManeCraft automatically compensates for wear and requires no adjustment, and will not damage the shaft, offering a leak-free seal to keep bilges dry and clean. After installation all they require is a quick regular inspection, in common with all other fittings under the waterline. On monitored vessels ManeCraft have completed in excess of 10,000 hours of service or 10,000 sea miles. They also have the advantage of a built-in emergency safety seal for added security and are ABS and GL approved. ManeGuide rudderstock seals Rudderstock seals are available in both radial and axial sealing solutions. In both cases they are derived from ManeBar and MKII seals and adapted to this specific application. This design offers simple installation in situ without having to lower the rudderstock, offering savings in time and expense. ER-type seal 89
