Examples of Wärtsilä’s achievements in environmental care are RT-flex engines, dual-fuel engines for LNG carriers and environmentally friendly stern tube sealing systems. IMO NO X EMISSIONS AND WÄRTSILÄ ENGINES The exhaust emissions regulations in Annex VI of the MARPOL 73/78 convention that entered into force on 19 May 2005 are now referred to as IMO Tier I. In October 2008, the Marine Environment Protection Committee (MEPC) of IMO adopted amendments to the MARPOL Annex VI regulations. These specify further NO X emission limits to be known as IMO Tier II and Tier X III. Under IMO Tier II, the NO X emission limits for engines installed in ships X constructed on or after 1 January 2011 will be reduced, according to a speed- dependent function, about 20% from IMO Tier I levels (see chart). All Wärtsilä engines included in this booklet comply with the NO X limits specified by IMO X Tier II. The emission levels have been lowered largely by reducing the maximum combustion temperatures. This has involved a combination of measures: Early inlet valve closing (Miller timing), optimization of the combustion chamber, and optimization of the fuel injection equipment. This has reduced the emissions with only a marginal decrease in efficiency, or none at all. 11 Under IMO Tier III, the NO X emission limit for engines installed in ships X constructed on or after 1 January 2016 will be reduced, according to a speed- dependent function, 80% from IMO Tier I levels (see chart), when the ship is operating in a designated Emission Control Area. Outside designated Emission Control Areas Tier II limits apply. Wärtsilä will adapt its engines to comply with the new upcoming NO X emission regulations. ENVIRONMENTAL CERTIFICATIONS Wärtsilä offers a wide range of products to assist in fulfilling environmental certifications as Clean Design defined by Det Norske Veritas (DNV). The purpose of the certifications, and thus also of Wärtsilä environmental equipments, is to reduce and limit the ship’s air emissions and sea pollution. Wärtsilä offers products that fulfil requirements for air emissions (NO X and X SO X ), ballast water treatment and oily water separation. Green Passport is XX available for most of the equipment presented in this booklet.

When operating the engine in gas mode the exhaust emissions are extremely low. In gas mode operation, the NO X emissions are over 80% below X the current IMO level, complying with the upcoming IMO Tier III standard. The SO X emissions are almost negligible and the amount of emitted particles X is less than 10% compared to a conventional marine diesel engine running on diesel. Further, gas operation in general generates 25–30% lower CO 2 emissions compared to diesel operation. The gas engine is a clean, reliable and high efficiency engine. The engine is a perfect solution when the target is to achieve low exhaust emissions in a cost efficient way. WÄRTSILÄ COMMON-RAIL Wärtsilä common-rail engines, branded as RT-flex for low-speed engines and EnviroEngine for medium-speed engines, offer distinct benefits to ship owners. One of the major benefits is smokeless operation at all engine load levels, also at low load and low revolution speed. The lower running costs of Wärtsilä common-rail engines derive from reduced maintenance and lower part-load fuel consumption. Precise control of injection and high injection pressures at all speeds give steady running at very low running speeds without smoking, down to 10–12% of nominal speed for low-speed engines. Particular attention has been paid to making the system reliable. The common-rail concept also has inherent redundancy, adding to reliability and safety. The design of the common-rail system is optimized for new engines but it can also be retrofitted to existing engines. WÄRTSILÄ LOW LOSS CONCEPT The Wärtsilä Low Loss Concept (LLC) is a specially developed and patented diesel electric system. One of the LLC features is reduced electrical losses compared to conventional diesel electric systems. This saves fuel and reduces exhaust gas emissions. The LLC obviates the need for propulsion transformers with associated electric losses. Results from full scale measurements have shown total electric losses in the range of 6% for the LLC, which is significantly less than in conventional systems. 12 13 ENERGOPAC Fuel savings and a reduction in emissions can be achieved with Wärtsilä Energopac. This is an integrated propulsion and steering system which increases the propulsion efficiency, but does not compromise on manoeuvring characteristics and comfort levels. Energopac includes a special propeller design, a sophisticated high-lift flap rudder equipped with an efficiency bulb and a special fairing cap connected to the propeller hub. The bulb and fairing cap work together to streamline the water flow behind the propeller while the twisted leading edge and rudderflap reduce rudder drag. Depending on the specific application, the power savings and emissions control with Wärtsilä Energopac may result in operational savings of up to 9%. WÄRTSILÄ HIGH EFFICIENCY NOZZLE The Wärtsilä high efficiency nozzles differ from conventional nozzles through a special rounded leading edge and S-shaped outer surface. Since their introduction with small propellers (less than 3.5 m diameter), several hundred have 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%. ENVIROSEALS: OCEANGUARD AND AIRGUARD Any oil loss to the environment from a ship’s stern shaft sealing system is unacceptable. Enviroseals offer pollution-free sealing systems with a proven track record on all types of vessels. Enviroseals are equally suited to retrofitting on existing standard seal installations or, as is now common, to be specified by owners for new-buildings. Wärtsilä’s Enviroseal systems prevent both the leakage of bearing oil into the sea 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. The Oceanguard system is unique in that it enables all potentially polluting oil to be contained within the vessel, using a double barrier comprising a combination of face seal and lip seal technologies and a low-pressure void space. This sealing system is ideal for use on cruise ships and ferries. The Airguard system, with its air-induced controlled pressure components, ensures the seal is a truly anti-pollution lip seal. This sealing system is ideal for use on LNG carriers, container ships, bulk carriers and many other vessel types. 14 HIGH-EFFICIENCY WASTE HEAT RECOVERY (WHR) Waste heat recovery is an effective technology for simultaneously cutting exhaust gas emissions and reducing fuel consumption. High-Efficiency Waste Heat Recovery plants can be installed with Wärtsilä engines. This enables up to 12% of the main engine shaft power to be recovered as electrical power for use as additional ship propulsion power and for shipboard services. These WHR plants thus cut exhaust gas emissions and deliver fuel savings of up to 12%. Steam based WHR has already been successfully fitted in several installations to Wärtsilä RT-flex low-speed marine engines. In the WHR plant, a turbo-generator combines input from a steam turbine and an exhaust gas power turbine to generate electrical power while steam from the economizer is available for ship service heating. Steam based WHR is recommended for vessels with high installed power. For vessels with lower installed power the excess heat can be recovered with an Organic Rankine Cycle (ORC). A non-flammable and non-toxic media is used to utilize exhaust gas heat and also lower grade heat sources like HT water from the engines. Due to the flexibility of an ORC plant, the system can achieve the same efficiency as in the steam cycle.

Particulate matters are considered to be simultaneously reduced with SO X . The regulation has different SO X limitations and time of implementation: X tighter limitations will be applied earlier in emission control areas, while the global sulphur cap will be significantly reduced by 2020 or 2025 (in case of postponement of the implementation year). There are no restrictions in the use of high sulphur heavy fuel oil and abatement technologies are allowed for achieving compliance. Exhaust gas scrubbing is a cost effective alternative to low sulphur content fuels for reducing SO X emissions. Wärtsilä has developed a feasible solution, X both for new installations and as a retrofit to existing ships. Combustion units can be diesel engines of any type or application, 2-stroke or 4-stroke. The SO X removal efficiency of the Wärtsilä FW scrubber system is over X 97%, making it possible to operate with 3.5% sulphur fuel and still comply with the 0.1% sulphur fuel limit. Wärtsilä FW (fresh water) scrubber concept is based on a closed loop system, using fresh water with caustic soda (NaOH) addition to the scrubbing water. There are different scrubber configurations available. Main Stream Scrubber is designed to be installed in the main exhaust gas stream of an individual diesel engine. Integrated Scrubber is based on design where one single unit can clean the exhaust gases of several main and auxiliary engines and oil-fired boilers onboard. The scrubber system is equipped with an automation system for operation, emissions monitoring and safety control. Wärtsilä FW scrubber system has been approved by classification societies. 16 WÄRTSILÄ NOR Wärtsilä has developed a NO X reducer (NOR) based on selective, catalytic X reduction technologies. The programme covers Wärtsilä’s medium-speed engine portfolio. The reduction in NO X emissions is 85–95%. X The size of the NOR is optimized in terms of performance and costs. The main components of the SCR installation are the reactor, which is the core of the installation, a reagent pumping unit, a dosing unit for controlling the reagent flow, and an injection unit for feeding the reagent into the duct. The dosing unit is provided with a dedicated control cabinet. An emission monitoring system is available as option.

The technology behind the Wärtsilä OWS M-series is a combination of optimized traditional methods and innovative new solutions. The separator consists of a four-stage, emulsion-breaking unit, where each stage handles one key component of the sludge and bilge mix. It can handle input flows with an oil content of between 0 and 100%, making it the most versatile separator on the market. All Wärtsilä M-series units have successfully passed USCG / IMO type approval in accordance with 46 CFR §162.050 and MEPC.107(49). The amount of oil in water after treatment is guaranteed to be less than 5 ppm.

Should the oil content rise above the set limit, the flow will be re- reouted back to the bilge tank. The system logs the discharge quantity and oil content as well as time and location of the ship. All data is stored in memory for later retrieval. The system is enclosed in a locked, tamper-proof cabinet and all accesses are logged in memory. For both crew members and ship management, the Wärtsilä BilgeGuard provides a priceless safety net that makes the compliance with applicable regulations evident. Wärtsilä BWT 500i. 19 BALLAST WATER TREATMENT The Wärtsilä product for Ballast Water Treatment is named Wärtsilä BWT 500i. The Wärtsilä BWT 500i is a complete ballast water treatment system designed for a flow rate of 500 m 3 /h (several units can be installed in parallel for higher flow rates). Wärtsilä BWT 500i is based on filtration and UV disinfection treatment. The treatment system is unique because the actual system incorporates both filter and the UV reactor in a single integrated unit. The integrated concept offers a number of advantages, including a smaller footprint, reduced pressure drop and lower power draw. The system control panel, driver panel and switch gear panel for the UV reactor are included in the system as separate units. The Wärtsilä BWT 500i has been purpose built for marine applications and fulfils the requirements in the IMO Global Ballast Water Convention 2004, which clearly states how ballast water should be treated before release into the sea. 20 WÄRTSILÄ INTEGRATED AUTOMATION The Wärtsilä integrated automation system is a new-generation vessel automation system based on a distributed architecture and transparent integration with the Wärtsilä engine control and propulsion system. It also covers all third-party systems onboard. Wärtsilä offers scaleable systems from small alarm and monitoring systems to advanced integrated automation systems. The integrated automation system is easy to install and has a number of enhanced applications: z Alarm and Monitoring z Power generation z Propulsion z HVAC z Utilities z Ballast z Power distribution z Thrusters z Engines z Cargo z Power management. Propulsion optimization Power management The complexity of the integrated automation system reflects the type of vessel and the functionality onboard. We offer a wide range of configurations for various needs. The integrated automation system has an easy, standardized interface common with the other systems onboard. Both shipowners and shipyards are ensured full lifecycle support from design, installation and commissioning to operation throughout the lifespan of the vessel. 21 Vessel process control Vessel performance 22 Based on data from all essential vessel systems, we can offer a performance estimator integrated in the control system that enables ship owners and operators to manage the vessel more economically and environmentally friendly. The system includes fuel and power optimization and reporting based on hull performance, power production, cargo and navigational data. WÄRTSILÄ POWER MANAGEMENT The Wärtsilä power management system provides effective control and monitoring of the power plant and power consumption. Power management covers the entire chain from the power generating units, switchgear, power distribution network and variable speed units to the power users. The complexity of the power distribution control is built into the system so as to achieve the maximum efficiency performance. Each installation is therefore configured individually. WÄRTSILÄ CONTROL SYSTEMS UNIFIED CONTROLS Wärtsilä unified controls, UNIC, introduce a flexible and fully scalable control system for large reciprocating diesel and gas engines. 23 HIGH RELIABILITY AND EFFICIENT DESIGN The UNIC system is designed to fulfil the long lifetime expectations for large marine diesel and gas engines operating in the toughest of conditions. The system is based on a high degree of commonalities and standard interfaces, covering different engine sizes and fuel systems in a modular way. A modular, standardized interface provides the designer of the off-engine automation systems with easily reusable design. It allows conversion of for example diesel engines to dual fuel or common rail with a minimum of modifications. Due to the pre-tested configuration, the engine or generating set is operational with a minimum of commissioning and installation work. The critical parts of the UNIC system are either redundant or very fault-tolerant to enhance high safety and availability in all circumstances. In particular, parts like the communication and power supply are fully redundant to allow single failures without interruptions in engine operation. Thanks to the electronic control, the engine can be adapted to different operating conditions. Key features of the UNIC system are a complete engine safety system, local monitoring, speed control with loadsharing, fuel injection, timing control, knock detection, alarm signal aquisition, start/stop sequencing, load reduction request, system diagnostics and fieldbus interface as applicable for each engine configuration.

CAN UNIC 24 WÄRTSILÄ PROPULSION CONTROLS OPTIMIZED CONTROL OF THE PROPULSION MACHINERY The Wärtsilä Propulsion Controls are 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 The Wärtsilä Propulsion Controls are designed to optimize the control of any propulsion machinery. The system exists in two versions, basic and advanced. The Wärtsilä Propulsion Controls basic is a cost effective standardized 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 Wärtsilä Propulsion Controls advanced introduces a modular designed system with communication on a two-wire field bus. This gives high flexibility and multifunctionality. This system is equaly suitable for single and twin engine configurations. 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 optimize ship operations are available. A user-friendly operator panel is supplied. It gives information of the propulsion plant and is used for calibrating of the system. Main bridge panel for CPP Propulsion Controls. 25 SPECIAL FUNCTIONS INCLUDE: z Pitch reduction zone – reduces propeller wear z Windmilling prevention z PTI/PTO functions z Multiple combinator modes z Frequency variation mode z Cruise control z Fine tuning pitch z Electric shaft levers REMOTE CONTROL FOR JETS These systems are similar to the one used for controllable pitch propellers, except for the integrated joystick system which is an option for catamarans and monohulls. For monohulls with joystick control a bow thruster is also required. The joystick is a single lever system for enhancing manoeuvring. REMOTE CONTROL FOR AZIMUTHING THRUSTERS For vessels such as harbour tugs, an integrated control concept similar to that for jets is available. For large off-shore platforms, individual controls for propulsion and steering are available. These include standardized interfaces with third party DP-systems. Main bridge panel for Waterjet Controls. 26 CONTROLS Cost effective universal controls for any propulsion system z Robust design with type approval z Joystick available for small and large vessels z Field bus application available WÄRTSILÄ JOYSTICK CO-ORDINATING CONTROL SYSTEM The Wärtsilä Joystick 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 Wärtsilä Joystick is available, including features such as a simplex DP-mode and anchoring mode. 27 WÄRTSILÄ VARIABLE SPEED DRIVE The variable speed drive is specially designed for lifetime operation in a maritime environment. It is the world’s most compact, low voltage (690V) variable speed drive with excellent performance in control of propulsion motors, pump applications, compressors, mooring and winches, and drilling operations. The drive is water cooled and can be directly connected to the ship’s cooling water system. Other important features are the redundant design and interchangeable power modules, which give an easy and efficient service concept. WÄRTSILÄ PASSIVE RECTIFIER The variable speed drive can be delivered with a diode rectifier in a 12 pulse or 24 pulse configuration, very well suited to either a Wärtsilä LLC system or a standard transformer solution. WÄRTSILÄ ACTIVE FRONT END RECTIFIER The variable speed drive can also be delivered with an active rectifier front end which allows for energy flow in both directions, eliminating the need for transformers and braking resistors. Direct Current Control and network filter give small ripple currents and very low harmonic distortion.

Combined with our patented electronic DC breakers, these work independently. The multidrive system can be connected to the main grid through either active or diode rectifiers, and also allows for DC-sources such as batteries and fuel cells. 29 WÄRTSILÄ SWITCHBOARDS Wärtsilä low and medium voltage switchboard systems are optimized for marine use. When developing our switchboard systems, the need for easy installation and maintenance is a key consideration. The system is module-based and, therefore, very flexible. Later extensions can also be easily added.

WÄRTSILÄ RT-flex96C IMO Tier II Main data: Version B, also available as traditional RTA type 47 Typical BSFC curves to illustrate Standard Tuning, Delta Tuning and Low-Load Tuning. BSFC LOAD Standard tuning Delta tuning Low-load tuning DEFINITIONS AND NOTES FOR LOW-SPEED ENGINES DIMENSIONS AND WEIGHTS z All dimensions are in millimetres and are not binding. z 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, and for ISO standard reference conditions (ISO 15550 and 3046). The BSFC figures for Wärtsilä engines are given with a tolerance of +5%. Wärtsilä RT-flex engines have a lower part-load fuel consumption than the corresponding Wärtsilä RTA engines. Wärtsilä RT-flex engines are also available with Delta Tuning and the RT-flex82C and RT-flex96C also with Low- Load Tuning for even lower part-load fuel consumptions (see chart). Low-Load Tuning will also be introduced to the other RT-flex engines in the portfolio. Delta Tuning and Low-Load Tuning both take advantage of the complete flexibility in engine setting provided by the RT-flex common-rail system to optimize fuel injection pressures and timing at all loads. Delta Tuning focuses on reducing BSFC in the operating range below 90% engine load. 48 Low-Load Tuning further reduces BSFC in the operating range below 75% engine load by means of a modified turbocharging system layout in combination with appropriately adjusted RT-flex system parameters. ISO STANDARD REFERENCE CONDITIONS Total barometric pressure at R1 ............................................ 1.0 bar Suction air temperature ............................................ 25 °C Relative humidity ............................................ 30% Scavenge air cooling water temperature................................ 25 °C IMO NO X EMISSIONS All Wärtsilä low-speed engines included in this booklet comply with the NO X limits specified in Annex VI of the MARPOL 73/78 convention. For the X amended regulations under IMO Tier II and Tier III, please see page 10. The latest versions of these engine types are available either complying with the amended regulations under IMO Tier II, or complying with the existing IMO Tier I regulations. Previous versions of these engine types comply only with existing IMO Tier I regulations. Compliance with the IMO Tier II NO X emissions limits involves a small X increase in fuel consumption compared with the BSFC with the Tier I limits. Wärtsilä RT-flex electronically-controlled common-rail low-speed engines will comply with the Tier II NO X emissions limits with a smaller increase in fuel X consumption than Wärtsilä RTA low-speed engines. Provisions for compliance with IMO Tier III NO X emissions limits will be X announced at a later date but in ample time for the implementation date. 49 RATING POINTS FOR WÄRTSILÄ LOW-SPEED ENGINES The engine layout fields for Wärtsilä low- speed engines are defined by the power/ speed rating points R1, R2, R3 and R4 (see diagram to the right). In certain engines, the layout field is extended to the points R1+ and R2+. R1, or R1+ instead if applicable, 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. CYLINDER LUBRICATION The load-dependent accumulator cylinder lubricating system has proven reliable in operation since its introduction in the 1970s. It is employed as standard on Wärtsilä RTA low-speed engines of smaller bore. To enable lubricating oil feed rates to be reduced, the accumulator system has been further developed in recent years. The new Pulse Lubricating System with electronic control of lubrication timing has been developed. It is available for all Wärtsilä RT-flex low-speed engines and for selected RTA engines. The guide lubricating oil feed rate with the Pulse Lubricating System is 0.7 g/kWh. This allows important savings in engine operating costs. For further information on this subject, please consult your nearest Wärtsilä company. 50 WÄRTSILÄ MEDIUM-SPEED ENGINES DIESEL ENGINES The design of the Wärtsilä medium-speed engine range is based on the vast amount of knowledge accumulated over years of successful operation. Robust engines derived from pioneering heavy fuel technology have been engineered to provide unquestionable benefits for the owners and operators of Wärtsilä engines and generating sets: z Proven reliability z Low emissions z Low operating costs z Fuel flexibility Benefits for the shipyard include installation friendliness, embedded automation system, and built-on modularized auxiliary systems.

The Wärtsilä low loss concept is a patented solution developed to enhance redundancy and to reduce the number of components in the system. The concept is flexible and can be designed to fit any configuration of power generation units and propulsion units as well as other electric power consumers onboard. In addition to tailor-made solutions, the low loss concept is available in five standardized systems: Wärtsilä low loss concept 1500, 2700, 3800, 5000 and 10,000 indicating the maximum power of each of the two main propellers. For vessels with large power generation and power consumption, a medium voltage system is available. The system can be combined with Wärtsilä’s variable speed drives powering up to 10 MW propulsion units. The system can be combined with any configuration of power generation units and can be tailor-made to meet specific requirements for flexible power distribution in a variety of different applications. A combination of a medium voltage system for power generation and a low voltage system for power distribution to the ship consumers and to special purposes will enhance the flexibility and increase the operability of the vessel. 75 Wärtsilä 8L32 Generator Switchboard LLC-unit VSD VSD = Variable Speed Drive Transverse thruster Tunnel thruster Main propulsion thruster Forward azimuth thruster Steerable thruster VSD V S D V S D LLC-unit 76 WÄRTSILÄ AUXPAC The Auxpac generating sets are available in a selected range as pre- engineered and pre-commissioned auxiliary generating sets.

Wärtsilä has successfully installed waterjets in various landing craft and other applications that require shallow water access, high maneuverability or low noise and vibration levels. In addition, Wärtsilä’s Waterjet and Refined Propeller (WARP) system offers a solution for craft with a versatile operating requirement around 30 knots. Usually about one third of the total vessel power is linked to two propellers with the rest of the power for the central boost waterjet. The advantage is reduced vessel draft with optimized propeller diameter for efficient cruising around 20 knots. For top vessel speed around 30 knots the propellers and the waterjet are designed to jointly achieve the thrust required. Wärtsilä is leading the market for WARP systems with several Navy, Ferry and Yacht applications in operation with both controllable & fixed pitch propeller – waterjet combinations. 104 WATERJET TYPES Wärtsilä has a unique portfolio of waterjet types available. The right waterjet for your application will be selected based on the operating profile and the required ship interface. The operating profile will determine the type of pump to be selected. For high power dense, high speed applications above 50 knots, a non-axial E-type pump design is available, delivering optimum performance for extreme vessels. For applications that require optimum propulsion efficiency for design speeds below 45–50 knots, our axial geometry waterjet designs are the optimized match. Our axial waterjet design is the most compact and most light weight waterjet design available in the full stainless high-end waterjet market, offering extra thrust at the low end of the speed range for top acceleration. PRE-ASSEMBLED PACKAGES, WÄRTSILÄ SRF DESIGN For ease of installation with minimum ship interfaces, waterjet sizes up to the 810 can be delivered in an easy install package with all auxiliary systems pre-mounted. The waterjet inlet duct is included in the scope of supply with impeller shaft and bearings delivered pre-aligned on a ready-install skid. The most compact, easy install waterjet package available in the market with stainless steel impeller and a unique stainless steel stator section for vessel top performance long after initial newbuild sea trials. Other system materials are optimized for use with light weight aluminium or composite crafts. 105 The design has all oil-lubricated or oil-containing parts mounted inboard of the vessel, and it is the only easy install waterjet package in the market with a compact steering and reversing assembly not extending outside the transom mounting flange diameter. Aluminium materials are avoided for the stator bowl and the full stainless stator section with the stainless impeller and shaft provides optimum resistance against abrasive wear of the stator blades. Deterioration of the stator blade profile should be avoided wherever possible since they play an important role in the largest energy transformation that takes place in a jet system. For vessels requiring top performance – also long after initial newbuild sea trials – a stainless stator section will deliver its value.

A C D E F B 106 WATERJET SIZE SELECTION The graphs below indicate the jet size required based on the relation between the engine power and the design speed of the vessel. For instance a ship with four 1250 kW engines and a corresponding vessel speed of 33 knots will need four 510 size waterjets. A ship with a design speed of 40 knots at 1250 kW power can use 450 size waterjets. The correct jet size is thus indicated by the line above the intersection of the power and the corresponding vessel speed (see examples in graphs below). 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 optimized jet selection based on specific vessel design parameters, operating profile or for details of waterjets above 50 knots or 30 000 kW.

WÄRTSILÄ AXIAL JET SERIES, 6-BLADED WATERJETS GENERIC WEIGHTS AND DIMENSIONS FOR THE MOST OFTEN USED WATERJET SIZES 109 WÄRTSILÄ HIGH EFFICIENCY NOZZLE Fitting 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 engine. The improved Wärtsilä high efficiency nozzle, type HR and HP, combined with a Wärtsilä propeller, can produce up to 10% more thrust than conventional nozzles, both in bollard pull and in free sailing condition. The nozzle profile offers a double profiled cross section (outside and innerside). This sophisticated shape improves the water flow both into and out of the nozzle, increasing thrust performance. ENERGOPAC Energopac is the optimized propulsion and manoeuvring solution for coastal and sea going vessels. The key objective is to reduce the vessel’s fuel consumption by integrating both propeller and rudder design. Each Energopac is designed to fit the vessel and to meet its specific requirements; this allows Energopac to be optimized fully for energy efficiency, whilst not compromising on either manoeuvrability or comfort levels. FUEL SAVINGS Energopac reduces fuel consumption because it reduces flow separation behind the propeller hub in an effective way. Extended studies show that for Two Wärtsilä FP propellers in HR nozzles. 110 the same course-keeping capabilities, Energopac will create less drag than conventional rudder systems. Especially when using small – corrective – steering forces to keep your vessel on course, the difference in rudder resistance is significant. The high-lift performance of Energopac requires smaller steering angles and consequently reduces the rudder resistance. DESIGN SPACE The application of Energopac gives more freedom to optimize between conflicting requirements. High performance propeller designs are often a compromise between increased efficiency and reduced vibration levels. Energopac allows for a propeller design, that gives the optimal balance between these requirements. TYPICAL APPLICATIONS Energopac will effectively reduce the operational costs for any vessel with a considerable share of free sailing time in its operational profile. Additionally, it will work very well for propellers with a relatively large propeller hub. The potential savings are large for vessels with highly loaded controllable pitch propeller systems such as RoRo-vessels, ferries, container / multipurpose vessels and vessels with an ice class notation. COST SAVINGS WITH ENERGOPAC The reduction in fuel consumption depends very much on the vessel type, the operational profile of the vessel and also on the reference propeller and rudder. For any application, the power savings can be estimated by Wärtsilä. The estimate is based on the vessel design, operational profile and other requirements. Proven savings in required power for a vessel’s trial speed vary between 2–9% with Energopac. 111 112 WÄRTSILÄ 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 (PTO) All Wärtsilä gears can be supplied with one or more PTOs for driving the shaft alternator, compressor or pump. For single vertical and horizontal gears, the standard PTO is primary driven. For twin input-single output gears the PTO is optionally primary or secondary driven. z A primary driven PTO is rotating whenever the engine is rotating. z A secondary driven PTO is rotating whenever the propeller shaft is rotating. Two speed PTOs are available for gear types SCV85-SCV128.

In PTI mode the shaft alternator can also be used as an electric motor. PTI is normally used for the following operation modes: z PTI “Booster” mode is used when the main power of the engine is too small, in order to increase the total propulsion power. For this mode, no clutches are required on the gear. z PTI “Take me home” mode is used in case of emergency, if the prime mover is out of operation. For this mode a minimum of 2 clutches are required on the gear. Two speed PTO/PTIs are available for gear types SCV85-SCV128. INTEGRATED OR SEPARATE HYDRAULIC SYSTEM FOR GEAR AND CP PROPELLER Most Wärtsilä gears are purposely-designed with an integrated hydraulic system for both the gear and the CP propeller. As the separate hydraulic power unit for the CP propeller is superfluous, both installation costs for the yard and operational costs for the owner are reduced. 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.

Stern tube (open or closed) Water Wärtsilä Stern Tube Auxiliaries Water conditioning Inboard/water Standard and premium filtration packages to optimize the life of propulsion components in dirty water applications. OIL LUBRICATED LIP SEALS FOR PROPELLER SHAFTS The oil lubricated lip seal portfolio comprises seals in various configurations suitable for stern tubes, thrusters and pods etc. The seal rings are developed and produced in-house from Viton® which provides exceptionally high resistance to wear and attack by either sea water or oil. CONVENTIONAL LIP SEALS The OLS3-P is a conventional seal system with 3 seal rings and the OLS4-P has an additional standby seal ring for increased reliability. The 4th seal ring can be activated in the rare case of oil leakage occurring to the sea to overcome the leakage and to enable continued operation of the vessel. ENHANCED LIP SEALS The environmental anti-pollution systems OLS3-PA & OLS4-PA operate by separating the oil and water seal rings by a pressurised air space that is drained and monitored inboard. The oil pressure in the stern tube and air pressure in the air chamber fluctuates to allow for varying vessel draughts giving the seal optimum performance and increased life. The OLS3-PA has 3 seal rings and the OLS4-PA has an additional stand-by seal ring. LIP SEALS FOR DREDGER / ABRASIVE WATER APPLICATIONS A further enhanced seal, ideally suited to operation in muddy / sandy water, is available in conventional and environmental versions with or without a stand-by seal ring. The system provides a continuous water flush to prevent the ingress of any abrasives to the seal. The above mentioned lip seal systems come with an OLS2-P forward lip seal comprising 2 seal rings for security inboard. 120 OLS4-PA OLS3-P OIL LUBRICATED LIP SEALS FOR RUDDER STOCKS OLR2-P & OLR3-P seals are equipped with 2 & 3 seal rings respectively. For rudder stocks, where the seals use no shaft liner the seal rings slide directly on the shaft, the seal rings are therefore produced in NBR. OIL LUBRICATED FACE SEALS FOR PROPELLER SHAFTS A broad range of outboard seals is available in various configurations comprising face only and face/lip combinations. These incorporate very hard wearing external sealing interfaces, corrosion resistant metal components and flexible bellows. The excellent designs and use of high quality materials ensure excellent performance and longevity. Further security is available with optional rope / net protection devices. NON-POLLUTING FACE SEALS This system is unique in that it enables all potentially polluting oil to be contained within the vessel, using a double barrier seal OFS3-P-H Muddy / sandy water Air Fresh water #1S/R #2S/R #3S/R FSP Fresh water Air Air chamber Stand-by seal 121 OLS3-PAW 122 separated by a vent space at atmospheric pressure, and a very low stern tube pressure of no more than 0.2 bar. FACE SEALS FOR SPECIALIST APPLICATIONS These face seals are ideal for use in specialist applications such as thrusters. OIL LUBRICATED FACE SEALS FOR RUDDER STOCKS This range is ideally suited to rudder stock applications. WATER LUBRICATED FACE SEALS When these water lubricated systems are used, the environment is safe. Thus they are ideal for use in environmentally sensitive areas. Wärtsilä’s extensive water lubricated face seal portfolio comprises various configurations, each suited to specific applications including stern tubes, water jets, submarines and rudder stocks. They can be used in open and closed systems and are suitable for ice class vessels. Typically the seals comprise two assemblies; one rotates with the shaft while the other is stationary. A flexible bellows ensures sustained and uniform contact between the seal interfaces during normal WFS1-MP-O WGFR1-MP-R WFS1-P-R/WFS1-F-R 123 ship and mechanical movements. The design enables the seal interfaces to be inspected without the need to disturb the propeller or shaft. BULKHEAD SEALS These ensure the integrity of water tight bulkheads where penetrated by a rotating shaft. They are bi-directional and thus can be fitted on either side of a bulkhead. WFB1-MF 124 OIL LUBRICATED WHITE METAL BEARINGS STERN TUBE BEARINGS White metal-lined stern tube bearings are designed for trouble free service throughout the life of a vessel. LINE SHAFT BEARINGS Used to support a propeller shaft between the engine and stern tube.

This has reduced the emissions with only a marginal decrease in efficiency. These specify further NOX emission limits to be known as IMO Tier II and Tier III. Under IMO Tier II. NOx emissions. or none at all. the NOX emission limits for engines installed in ships constructed on or after 1 January 2011 will be reduced. and optimization of the fuel injection equipment. All Wärtsilä engines included in this booklet comply with the NOX limits specified by IMO Tier II. the Marine Environment Protection Committee (MEPC) of IMO adopted amendments to the MARPOL Annex VI regulations. optimization of the combustion chamber. about 20% from IMO Tier I levels (see chart). The emission levels have been lowered largely by reducing the maximum combustion temperatures.Wärtsilä’s solutions are customized to specific ship design and operational requirements to ensure maximum efficiency. according to a speeddependent function. 2000 10 . This has involved a combination of measures: Early inlet valve closing (Miller timing).

ENVIRONMENTAL CERTIFICATIONS Wärtsilä offers a wide range of products to assist in fulfilling environmental certifications as Clean Design defined by Det Norske Veritas (DNV). Green Passport is available for most of the equipment presented in this booklet. also at low load and low revolution speed. This saves fuel and reduces exhaust gas emissions. complying with the upcoming IMO Tier III standard. In gas mode operation. The design of the common-rail system is optimized for new engines but it can also be retrofitted to existing engines. The common-rail concept also has inherent redundancy. reliable and high efficiency engine. the NOX emissions are over 80% below the current IMO level. offer distinct benefits to ship owners. branded as RT-flex for low-speed engines and EnviroEngine for medium-speed engines. The SOX emissions are almost negligible and the amount of emitted particles is less than 10% compared to a conventional marine diesel engine running on diesel.WÄRTSILÄ DUAL FUEL ENGINES WITH SUPERIOR ENVIRONMENTAL PERFORMANCE Gas operation gives a great environmental advantage compared to diesel mode seen from the exhaust gas emission point of view. Further. Results from full scale measurements have shown total electric losses in the range of 6% for the LLC. One of the major benefits is smokeless operation at all engine load levels. The lower running costs of Wärtsilä common-rail engines derive from reduced maintenance and lower part-load fuel consumption. The gas engine is a clean. WÄRTSILÄ LOW LOSS CONCEPT The Wärtsilä Low Loss Concept (LLC) is a specially developed and patented diesel electric system. down to 10–12% of nominal speed for low-speed engines. The engine is a perfect solution when the target is to achieve low exhaust emissions in a cost efficient way. which is significantly less than in conventional systems. One of the LLC features is reduced electrical losses compared to conventional diesel electric systems. Precise control of injection and high injection pressures at all speeds give steady running at very low running speeds without smoking. The LLC obviates the need for propulsion transformers with associated electric losses. When operating the engine in gas mode the exhaust emissions are extremely low. adding to reliability and safety. gas operation in general generates 25–30% lower CO2 emissions compared to diesel operation. Particular attention has been paid to making the system reliable. 12 . WÄRTSILÄ COMMON-RAIL Wärtsilä common-rail engines. Wärtsilä’s Enviroseal systems prevent both the leakage of bearing oil into the sea and the ingress of water into the bearing system.ENERGOPAC Fuel savings and a reduction in emissions can be achieved with Wärtsilä Energopac. Enviroseals offer pollution-free sealing systems with a proven track record on all types of vessels.5 m diameter). Energopac includes a special propeller design. The bulb and fairing cap work together to streamline the water flow behind the propeller while the twisted leading edge and rudderflap reduce rudder drag. the power savings and emissions control with Wärtsilä Energopac may result in operational savings of up to 9%. This is an integrated propulsion and steering system which increases the propulsion efficiency. but does not compromise on manoeuvring characteristics and comfort levels.

HIGH-EFFICIENCY WASTE HEAT RECOVERY (WHR) Waste heat recovery is an effective technology for simultaneously cutting exhaust gas emissions and reducing fuel consumption. Steam based WHR has already been successfully fitted in several installations to Wärtsilä RT-flex low-speed marine engines. Steam based WHR is recommended for vessels with high installed power. For vessels with lower installed power the excess heat can be recovered with an Organic Rankine Cycle (ORC). These WHR plants thus cut exhaust gas emissions and deliver fuel savings of up to 12%. A non-flammable and non-toxic media is used to utilize exhaust gas heat and also lower grade heat sources like HT water from the engines. the system can achieve the same efficiency as in the steam cycle. This enables up to 12% of the main engine shaft power to be recovered as electrical power for use as additional ship propulsion power and for shipboard services.

WÄRTSILÄ HIGH EFFICIENCY NOZZLE Fitting 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 engine. The improved Wärtsilä high efficiency nozzle, type HR and HP, combined with a Wärtsilä propeller, can produce up to 10% more thrust than conventional nozzles, both in bollard pull and in free sailing condition. The nozzle profile offers a double profiled cross section (outside and innerside). This sophisticated shape improves the water flow both into and out of the nozzle, increasing thrust performance. ENERGOPAC Energopac is the optimized propulsion and manoeuvring solution for coastal and sea going vessels. The key objective is to reduce the vessel’s fuel consumption by integrating both propeller and rudder design. Each Energopac is designed to fit the vessel and to meet its specific requirements; this allows Energopac to be optimized fully for energy efficiency, whilst not compromising on either manoeuvrability or comfort levels. FUEL SAVINGS Energopac reduces fuel consumption because it reduces flow separation behind the propeller hub in an effective way. Extended studies show that for 110 COST SAVINGS WITH ENERGOPAC The reduction in fuel consumption depends very much on the vessel type. Energopac allows for a propeller design. Energopac will create less drag than conventional rudder systems. Additionally. High performance propeller designs are often a compromise between increased efficiency and reduced vibration levels. 111 . The high-lift performance of Energopac requires smaller steering angles and consequently reduces the rudder resistance. container / multipurpose vessels and vessels with an ice class notation. ferries. For any application. the power savings can be estimated by Wärtsilä. TYPICAL APPLICATIONS Energopac will effectively reduce the operational costs for any vessel with a considerable share of free sailing time in its operational profile. DESIGN SPACE The application of Energopac gives more freedom to optimize between conflicting requirements. it will work very well for propellers with a relatively large propeller hub. The estimate is based on the vessel design. the operational profile of the vessel and also on the reference propeller and rudder. The potential savings are large for vessels with highly loaded controllable pitch propeller systems such as RoRo-vessels. the difference in rudder resistance is significant. operational profile and other requirements. Proven savings in required power for a vessel’s trial speed vary between 2–9% with Energopac.the same course-keeping capabilities. Especially when using small – corrective – steering forces to keep your vessel on course. that gives the optimal balance between these requirements.
