The global question behind the design of a vessel is the efficiency of the propulsion system. According to Wärtsilä, everything starts from the interaction between the hull and the propulsors. Then significant total savings can be found by optimizing the propeller design and matching it with the prime movers. Engine selection is another key element to improve the overall efficiency. Wärtsilä offers the configuration which provides the ability to match and run the engines close to optimum efficiency. Wärtsilä aims to deliver the optimum total solution and performance tailored to the specific operating profile of the vessel as defined by the end-user.

4 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 and generating sets, developed from pioneering heavy fuel technology, have been engineered to provide unquestionable benefits for the owners and operators of naval vessels. These benefits include: Reliability and low maintenance costs High thermal efficiency and low emissions Modular construction and reduced parts count Ergonomic interfaces Minimised consumables Cylinder liner with Anti-Polishing Ring Extended time between overhauls (up to 24,000 hours between top overhauls) Common Rail Technology Emission compliant with IMO Tier II All services from spare parts to reconditioning available from Wärtsilä s global network. ENGINE PERFORMANCE Wärtsilä 4-stroke engines utilize the latest developments in turbo-charging technology, which enables Miller valve timing and the Variable Inlet Valve Closing (VIC) system to be employed. At full-load operation, early closure of the inlet valves enables a low effective compression ratio, and as a result, comparatively low temperatures at the end of the compression stroke. The charge air, being both somewhat expanded and cooled on its way through the receiver into the cylinders, has a low global temperature that is still high enough to guarantee reliable and stable ignition of the fuel/air mixture in the combustion chamber. Due to the quick expansion of the combustion gases, high temperatures that are most critical to the formation of intensive NO X within the combustion chamber are rapidly abated. This combination creates a combustion process that is not only environmentally friendly, but also extremely efficient as the high expansion ratio produces the conditions needed for efficient utilization of the heat energy released by combustion at the beginning of the power stroke. 4 Wärtsilä 26 engine COMMON RAIL FUEL INJECTION TECHNOLOGY However, it is not only the choice of the compression/expansion ratio that makes Wärtsilä engines highly efficient. All versions of the engine are equipped with fuel injection systems that allow adjustment of the injection characteristics to the prevailing load conditions. The advanced common-rail fuel injection system offers the freedom to control and fine-tune the injection process. This enables full use of the engine s loading potential over a wide power range in order to achieve optimum fuel economy. Similarly, this freedom offered by the flexible fuel injection equipment can be utilized to adjust the engine to the existing limitations of exhaust gas emissions, to minimize smoke formation. Thermal load and mechanical stress levels are kept within the safety margins established by Wärtsilä over decades of engine development.

By utilising double mounting arrangements and acoustic enclosures naval standards are met and exceeded. Wärtsilä generating sets are in operation with many of the world navies providing electric power for diesel-electric propulsion and onboard ship services. INTEGRATED ELECTRIC PROPULSION (IEP) Engines from Wärtsilä s 20, 26, 32 and 38 range are driving IEP on the seven seas. Our customers include the Royal Navy with the Queen Elizabeth Class future aircraft carrier! Wärtsilä s reputation of excellence in the field is long established with the delivery of more than 50 generating sets used for the IEP of naval applications. vibration -30 db/-40 db AUXILIARY & EMERGENCY GENERATING SETS A wide range of generating sets is available for the supply of electric power for the vessel hotel load. Additionally, the reliability and efficiency of Wärtsilä products have convinced our customers to fit our generating sets within their scope of equipment for the electrical power source in emergency situations. ENGINEERING EXPERTISE The remaining and most efficient means of decreasing the force transmissibility, from the excitation source to the machinery foundation, can be achieved through the mounting of the noise sources in accordance with the following main design features: Installation of the engine, generator and auxiliaries on a common base frame. A static and dynamic analysis of the base frame design (stiffness of the seatings below the engine and generator fittings, natural frequencies and mode shapes) is generally done through a Finite Element Model. Selection of the number of resilient mount stages; at least one stage of resilient mounts between the common base frame and the machinery foundation on the ship s hull plating. If needed, in addition to the previous stage,a second resilient mounts stage is fitted between the engine and the base frame (and for some applications, between the generator and the base frame). Selection of the type of resilient mounts (natural frequencies generally in the range of 3 to 10 Hz, displacement capability from 10 mm up to 70 mm for some Navy applications with shock requirements). Design of the auxiliaries fitting and pipe clamping, which may have a significant influence on the resilient mounting efficiency. For some projects, an acoustic enclosure might be needed when the noise level in the engine room has to be below the standard engine airborne noise, or when the vibrations have been reduced to a very low level whereupon the underwater radiated noise may be influenced by the airborne noise of the diesel-generating set. 5

The increasing demand in stealth and shock resistance capabilities for fighting vessels leads to a definite necessity of enhancement on the already reliable technology used for commercial vessels. Navy applications often need tailor made solutions based on standard equipments in order to meet the typical very severe requirements such as high shock resistance, low noise and vibration levels. To fulfil such tough requirements, Wärtsilä, in cooperation with specialists in electronics or well known large water tank and cavitation tunnel facilities, has developed special features and designs. 6 PROPULSION TECHNOLOGIES The Wärtsilä Controllable Pitch propeller system consists of a hub, the propeller blades, shafting, hydraulics and a remote control system, as well as any further accessories needed to meet the navies requirements. The technologies available include: Advanced design by finite element method (FEM) and Computational Fluid Dynamic (CFD) giving high accuracy when designing the shock resistance capability and vibration modes of our installations Small hub size with reduced weight Increased loading capacity Compliant with EPA Vessel General Permit 2013 requirements Easy service (hub disassembly without pulling shaft REDUCED FUEL CONSUMPTION The Wärtsilä Controllable Pitch OPTI Design is the result of highly experienced design engineers in our European R&D headquarters having access to the very latest and most sophisticated software and analysis tools. Computational Fluid Dynamic (CFD) analyses of 3D geometries, analyse not only the propeller performance but most importantly also, the interaction between the propeller and hull. This provides extremely accurate information for achieving design and parametric optimisation. This state-of-the-art design protocol optimises the vessel s overall propulsive efficiency. OPTI Design can provide fuel savings of up to 4 percent. With each WCP propeller being individually customised to meet specific application requirements, the vessel s EEDI/ EEOI is improved. This in turn leads to reduced exhaust emissions.

WÄRTSILÄ S HYDRODYNAMIC DESIGN EXPERIENCE Our long history and experience in designing propellers gives us extensive hydrodynamic knowledge, and we have developed design tools validated by a large number of model test results, full-scale measurements, and research and development efforts. Co-operation with well known research institutes and universities worldwide ensures our prime position when it comes to propulsor hydrodynamics. Special noiseless blade profiles allowing cavitation free (i.e. silent) propellers up to speeds of 22 knots. Such blade designs and profiles are tested in partnership with the leading large cavitation tunnel facilities to achieve the highest level of underwater radiated noise and cavitation prediction. INTERNATIONAL COUNCIL FOR THE EXPLORATION OF THE SEA (ICES) For research ships, the Cooperative Research Project n 209 from the International Council for the Exploration of the Sea (ICES) [RB Mitson, Underwater Noise of Research Vessels, Review and Recommendations, 1995] gives recommendations on the underwater radiated noise. The main objective of these recommendations is to define a spectrum of acceptable underwater radiated noise levels to avoid any disturbance of the natural distribution of the fish but also to ensure that the fish target distributions and echo integrator results are free of bias due to high frequency noise. The noise levels should be measured for a ship sailing at 11 knots. PROPELLERS FOR RESEARCH SHIPS All the parts of a vessel contribute to the underwater radiated noise, the active inner parts (such as machinery) as well as the passive outer parts (the hull and its appendages) due to turbulence in the flow on these surfaces. The propellers become one of the essential sources of noise with the increasing vessel speed because of the occurrence and the extension of the cavitation phenomenon which increases dramatically the noise levels at all frequencies. The graphic shows the underwater radiated noise curves of different vessels equipped with Wärtsilä propellers, versus the ICES 209 curve, at 11 knots. 7

COLOMBIAN NAVY PZM OPV 7 de Agosto 2 x Wärtsilä 6L26 main engine 2 x Wärtsilä SCV56 gearboxes 2 x Lipstronic 7000 propeller system controls 2 x WCP-4D650D propeller system and shaftlines Wärtsilä Enviroguard seals Wärtsilä Envirosafe bearings FIXED PITCH PROPELLERS The Wärtsilä Fixed Pitch Propeller (FPP) OPTI Design is based on years of proven experience, more than 10,000 FPPs have been produced. They are designed using the most advanced technology and state-of-the- art equipment to ensure the highest possible levels of performance and efficiency. As a result, the end-user gain the benefits of lower operating costs and a reduced environmental footprint through less fuel consumption and fewer exhaust emissions. By being able to thoroughly analyse both propeller performance and the propellerhull interaction, we provide maximised efficiency. Model tests can be reduced and full-scale performance can be covered. It is simply a better propeller design concept that meets the needs of today s market. To ensure the highest fatigue strength, Wärtsilä maintains complete control over the production process. The result is optimal efficiency limits to minimise the weight. Wärtsilä has developed more than 25 different bronze alloys for marine propellers, the most commonly used being Cunial bronze. This copper, nickel, and aluminium alloy has unparalleled durability and reliability. Casting is an extremely complex procedure, and in order to assure a successful casting process, solidification simulation software is used for the more difficult geometries. The propellers can be produced with any required number of blades in diameters up to 12 meters. Both the propellers and shaft lines are designed to meet every possible Ice Class notation and are compliant with environmentally acceptable lubricants (EAL), as required for propulsors operating in US inland and coastal waters. GEARBOXES Wärtsilä gearbox design and production facility is based upon proven technology and experience. Our gears covers a power range of 1 to 25 MW for single input gearboxes with vertical or horizontal offset (with more than 350 gear configurations available), and 2 to 35 MW for twin input-single output type of gearboxes (with more than 100 gear configurations available).

FIRST PATROL VESSEL IN THE WORLD POWERED BY LNG The Finnish Border Coast Guard next generation OPV uses liquefied natural gas (LNG) with low emission levels and diesel oil as fuels, which keeps the ship s own emissions small. The Turva is powered by three eco-friendly Wärtsilä 34DF dual-fuel engines burning either crude oil-based marine fuels or liquefied natural gas (LNG). The engines can alternate among fuels without loss of power or speed. In the design of the vessel, special attention has been paid to environmentally friendly and energy-efficient solutions. As well as performing border management duties, the multipurpose vessel will serve in maritime search and rescue missions and demanding environmental safety operations such as oil spill response. NEW REQUIREMENTS ON SHIP EMISSIONS The International Maritime Organization (IMO) has approved amendments to the MARPOL Annex VI regulations on ship emissions. These regulations set stricter limits on emissions of Nitrogen Oxides (NOx) from the engines, as well as on the sulphur content of the fuel. The new requirements will enter into force in various phases during the years Wärtsilä 4-stroke engines are fully compliant with the IMO Tier II exhaust emissions regulations and can also be equipped with a SCR catalyst to meet IMO Tier III NOx emission levels. Being at the forefront of technological developments gives Wärtsilä many opportunities arising from the tightening environmental regulations. Wärtsilä has a multifaceted gas engine strategy, and can provide gas engines for vessels. Wärtsilä multi-fuel solutions provide full control over fuel choice without compromising performance. 9

12 WATERJETS Wärtsilä is the leading supplier of AXIAL flow stainless steel waterjets for high end applications: design and engineering of these waterjets combine advanced technology, reliability and ease of maintenance. Wärtsilä proposes also non-axial waterjets, successfully delivered worldwide since the 1970s. WÄRTSILÄ AXIAL WATERJETS Wärtsilä axial flow waterjets are a line of single stage compact high performance waterjets combining mixed flow properties with an axial build. The result is reduced transom occupation with highly increased cavitation margins. AVERAGE 25% REDUCED TRANSOM OCCUPATION Jet sizes are indicated by the front side diameter of the impeller seat ring. Nonaxial designs expand in a radial direction downstream directing the flow through the jet over a less efficient path. This results in a large transom flange diameter and often difficulties with fitting the jet in the available space either in width or height. The Wärtsilä axial waterjet series takes away all disadvantages by minimizing transom occupation and by offering an average 25% smaller diameter of the transom mounting flange. SOUTH AFRICAN NAVY VALOUR CLASS MEKO-A200 CORVETTES, SAS Amatola 2 x WCP-5C09N propeller system and shaftlines 1x LJ210E waterjet Wärtsilä Steerguard seals TKMS, Blohm + Voss GmbH UP TO 10% LOWER WEIGHT The reduced transom size not only results in reduced dimensions, but also gives a substantial lower weight of the installation. If this is combined with our welded jet construction allowing further weight optimizations, savings can be as high as 15% compared to non-axial build jet designs. AVERAGE 10% HIGHER ROTATIONAL SPEED = 10% LESS TORQUE Compared with non-axial design the rotational speed of the impeller is on average 10% higher while the impeller tip speed is still lower. The lower torque can give both weight and cost savings for couplings, shafts and gearboxes. LARGER MARGINS FOR OPERATING FLEXIBILITY AND MANOEUVRING The cavitation margins of the pump are shifted backwards with at least 35%. Due to this increase in cavitation margin and the lower impeller tip speed, more power can be allowed during manoeuvring resulting in a 15% higher manoeuvring thrust. Furthermore with the additional cavitation margin, operation with a reduced number of shaft lines is possible at a higher load of the remaining engines resulting in better operating flexibility. INCREASE IN POWER ABSORPTION AT MANOEUVRING During manoeuvring engines operate in a critical zone and waterjets tend to absorb increased power at a lower rotational speed of the impeller. The result is a high load for the engine resulting in smoke and an increased thermal load. The increase in power absorption of the Wärtsilä axial jet series is up to 70% Wärtsilä waterjet LJ210E, reverse bucket lower than of competing designs. DESIGN LAYOUTS All jet designs are available in a steering/ reversing (SR), reversing only (R) and booster execution (B). On request, Wärtsilä can supply designs for special applications for instance giving thrust in all directions 360 degree or offering shock compliant installations. The key benefits of the axial technology are valid for all executions. WÄRTSILÄ NON-AXIAL WATERJETS The non-axial E-type waterjet is still available in the Wärtsilä product portfolio for those applications requiring extreme speeds. 12

The ship, with an overall length of 127 m and full load displacement of 2,637 tons, is an innovative combatant designed to operate in shallow water environments to counter challenging threats in coastal regions, specifically mines, submarines and fast surface craft. LCS-2 is capable of speeds in excess of 40 knots and can operate in water less than 20 feet deep.

These systems combine controllable pitch propellers with a waterjet. The benefit is that the largest parts of the total installed vessel power can be absorbed by the waterjet. Despite the high amount of power the dimensions of the jet remain relatively small due to the high allowed power density compared to a propeller. With the jet taking most of the total vessel power, the propellers can remain small in diameter as well limiting the draft of the vessel. The result is a very attractive operational profile. The propellers are fully optimized for lower cruising speeds delivering optimum efficiency with low noise and vibrations. At the same time the combination of the waterjet and the propellers still gives access to higher speeds when required. Hybrid systems were delivered for various yachts with total vessel power up to 32 MW and for Navy vessels up to 28 MW. INCREASED CAVITATION MARGIN AT LOW SPEED Waterjet thrust and vessel resistance [relative, dimensionless] WLD - AXIAL FLOW CONTINUOUS CAVITATION LIMIT LJ - MIXED FLOW CONTINUOUS CAVITATION LIMIT VESSEL RESISTANCE Speed [knots] Full throttle = 100% MCR 95% MCR 90% MCR 85% MCR 80% MCR 75% MCR 70% MCR 65% MCR 60% MCR 55% MCR 50% MCR 45% MCR 40% MCR 35% MCR 30% MCR 25% MCR 20% MCR Increased cavitation margin at low speed shows the cavitation limit line for the WLD axial flow design (orange) and the LJ mixed flow design (blue). The area in between the lines is thus the achieved gain in cavitation margin for the new design. INCREASED PERFORMANCE In order to be able to respond to oncoming threats, Navy and Coastguard operators alike expect greater flexibility from their vessels. This being for fast acceleration where the waterjet needs to rapidly convert the engine power into thrust (particularly for planning hulls) as well as for low patrolling speeds where the waterjet needs to be able to operate for longer periods without restriction from cavitation. The Wärtsilä WLD range of waterjets permits prolonged continuous operation at low speeds without restriction. 13
