NOx Abatement

Wärtsilä NOX Reducer (NOR)

Generating Sets

A marine diesel engine installed on a ship constructed on or after 1 January 2016, and

operating in the North American ECA and the United States Caribbean Sea ECA, must

comply with the Tier III NOX standards. The same rule applies in the North Sea and

Baltic Sea for ships with keel laying on or after 1 January 2021.

The Wärtsilä NOX Reducer (NOR) is an emission after-treatment system based on the

Selective Catalytic Reduction (SCR) technology for Nitrogen Oxide (NOX) reduction.

The NOR is optimized and validated for Wärtsilä medium speed engines in terms of

reliability, flexibility, size and easy installation and maintenance onboard. It is available

for both new build and retrofits. Wärtsilä engines delivered with NOR are equipped

with exhaust gas temperature control to ensure the correct temperature for SCR

Fuel Gas Supply Systems

Fuel Gas Supply Systems

Wärtsilä Marine Power has the biggest experience and widest references in the

market of the LNG Fuel Gas Supply Systems.

Wärtsilä offers the LNGPac™ systems as a full ‘one-stop-shop’ supply and service

package that includes assistance for the ship design, the system classification

formalities, engineering, manufacturing, delivery, commissioning, lifecycle

maintenance and intelligent data utilization.

The LNGPac

Wärtsilä LNGPac™ is a complete fuel gas handling system for LNG-fuelled ships

consisting of several modules such as the bunkering station, the fuel tank, the

process and conditioning equipment as well as the control and monitoring system.

The LNG fuel system can be offered as a standalone product or as part of a

complete propulsion system. Besides, the customized package can be equipped

with patented features such as the cold recovery or the integrated Gas Valve Units.

Optional equipment can be included on request, such as nitrogen generators, gas

detection, ship to shore link and other optional features. Wärtsilä can deliver LNG

systems for propulsion and power generation for any applicable type of ship or low-

pressure (6/16 barg) dual fuel or gas engine, including WinGD and other engines’

makers.

The main modules of an LNGPac™

The Wärtsilä LNGPac™ systems are tailored made and are built by several modules

which are connected on board by the shipyard. Interconnecting piping can be offered

as an option.

The LNG STORAGE TANK

The main item of an LNGPac™ system is the LNG fuel storage tank which can is

normally an IMO type C storage tank, with vacuum or polyurethane insulation.

Wärtsilä collaborates also with other companies, such as GTT, for other tank

geometries or membrane tank based systems. Tank dimensions can be tailored

made according to customers’ needs.

The PROCESS EQUIPMENT

The process equipment can be delivered either mounted directly on the tank, in a

TANK CONNECTION SPACE, or in a unit detached from the tank normally called

FUEL GAS PREPARATION UNIT. Wärtsilä can deliver the Tank Connection Spaces as

open dome arrangements or built-on gastight enclosed units. Typical LNG processes

are based either on a pressure build up setup, a pump configuration or on a

combined use of pumps and compressors.

32

Fuel Gas Supply Systems

The BUNKERING STATION

Wartsila delivers standard skids at the bunkering station, designed according to

SGMF recommendations and main rules of reference.

AUTOMATION

Any LNGPac™ system comes with its own automation system ready for data sharing

and to be connected to the rest of Wartsila’s portfolio. The automation is developed

with an easy-to-use interface and ESD functionalities for the scope supplied. The

LNGPac™ operations, such as bunkering, BOG, management, and fuel gas supply

to consumers are fully automated and controlled with an HMI adapted to customer

needs. The LNGPac™ control system can be delivered integrated with the vessel

automation system (IAS) and with monitoring & remote access or diagnostics (CBM)

of Wärtsilä Life Cycle Services.

Complete Solution

The Wärtsilä LNGPac™ system is based on an IMO C-type LNG-storage tank with

either double-walled vacuum or single-walled polyurethane (PUR) insulation. All LNG

pipelines, e.g. from the bunker station to the tank are insulated. All necessary

process equipment is installed in a separate unit, which can be either mounted

directly to the LNG tank or placed remotely. The fuel gas process equipment

vaporizes the liquid LNG to natural gas and ensures correct fuel gas temperature and

pressure for the engines and other gas consumers. The LNGPac operations, such as

bunkering, BOG, management, and fuel gas supply to consumers is fully automated

and controlled with an HMI adopted to customer needs. The LNGPac control system

can be delivered integrated with the vessel automation system (IAS) and with

monitoring & remote access or diagnostics (CBM) of Wärtsilä Life Cycle Services.

Gas Valve Units

The Gas Valve Unit (GVU) is a module connected to the DF engine gas supply piping.

Each engine has its own dedicated GVU. The unit controls the gas pressure to the

engine according the engine load. Wärtsilä can deliver GVUs for both Wärtsilä 4-st DF

engines and WinGD 2-st DF engines.

Wärtsilä has three alternative solutions for GVU.

GVU-EDTM™ (enclosed design)

The GVU-EDTM™ is a solution where all gas related equipment is mounted inside a

gas tight enclosure. This arrangement allows the GVU to be placed inside safe area

for example the engine room. GVU location next to the engine gives the best engine

response and minimises the installation costs.

GVU-OD™ (open design)

The GVU-OD™ is a traditional solution that is used mainly for Gas Carrier. The GVU-

OD are delivered open-skid mounted and must be installed in a dedicated GVU room

(Hazardous area).

GVU Integrated

If the distance between the gas consumers and the LNGPac™ allows it, the GVU

equipment can be integrated with the rest of the LNGPac™ process equipment.

GVU Automation

The Wärtsilä GVUs comes as a complete module with the automation system. With

GVU-EDTM™ the automation is fixed in the unit frame and with GVU-OD™ control

cabinet is supplied as a loose item. The automation system consists of a control

cabinet and solenoid valves. With GVU-ED™ solenoids are located in dedicated

solenoid valve cabinet and with GVU-OD™ solenoids are directly mounted on the

valve actuators. The control cabinet gives control signal to solenoids and solenoids

are controlling pneumatic air feed to the valves. Therefore, unit is so called electro-

pneumatically operated. To increase safety each automation valve is monitored via

valve position sensors. The control cabinet is equipped with a LDU (Local Display Unit)

where the operator can read unit and valve statuses, sensor readings, possible active

alarms and alarm history. Furthermore, the alarms are send via Modbus Ethernet link

to the integrated ship automation system.

Options

Opening side

•   For the GVU-ED the opening of the enclosure can be made either on the left or

     right side.

Flow meter

•   The Wärtsilä GVUs can be supplied with an integrated flow meters to allow the ship

     owner to optimize the engine and keep record on the gas consumption. The used

     flow meter type is a Coriolis mass flow meter. This type of instrument gives  

     accurate measurements regardless of pressure and temperature. The flow meter is

     mounted on the GVU with an additional flow meter transmitter box.

36
Propulsors & Gears

Wärtsilä Gears

Wärtsilä gears have been designed to meet the highest standards of operational

efficiency, reliability and low noise and vibration.

Gear configurations:

•   1-speed gearboxes, for installations with a single engine and propeller    

     operating at a constant propeller speed. The Wärtsilä SCV designation  

     indicates a vertical offset, while SCH represents a horizontal offset.

•   2-speed gearboxes, for installations with a single engine and propeller able to

     operate at two selectable propeller speeds. The Wärtslä SCV/2 designation

     indicates a vertical offset, while SCH/2 represents a horizontal offset.

•   Double gearboxes, for installations with two engines and one propeller  

     operating at a constant rotational speed. “Twin-in single-out” gears with

     Wärtsilä designation TCH.

•   Special gearboxes, for instance gearboxes with both horizontal and vertical  

     offsets, are available upon request and are customised for the specific  

     application.

•   All Wärtsilä gears can be supplied with built-in multi-disc clutchesfor engaging

     the propeller.

Power take-off (PTO)

All Wärtsilä gears can be equipped with one or more PTOs for driving shaft

alternators, compressors or pumps. A clutch is optionally available for the PTO.

Specific fuel energy consumption

Most Wärtsilä gears can be supplied with a combined PTO/PTI. In PTI mode the shaft

alternator can be used as an electric motor to enable additional power for demanding

operations via the ‘PTI booster’. This functionality does not require any additional

clutch.

•   “PTI take me home” – an electrical drive mode used for emergencies if the

     prime mover is out of operation. This functionality requires two clutches: one  

     to disconnect the prime mover and one to engage the propeller in PTI mode.

Hydraulic system for the gear & controllable pitch (CP) propeller can be

integrated or separate

Most Wärtsilä gears are designed with an integrated propeller hydraulic system. This

provides a space efficient and highly reliable solution since the hydraulic pump is

driven mechanically by the gearbox. Optionally, all gears can be interfaced to a

separate hydraulic power unit as well.

Wärtsilä 2-speed Gears

The Wärtsilä 2-speed gear is designed to serve vessels having multiple operational

modes or reduced transit speeds. In particular, RoPax ferries, offshore support

vessels, tug boats and fishing vessels can gain notable economic and environmental

benefits. Single screw vessels with redundant propulsion system (“take me home

system”) will also benefit from this type of gear.

The key feature of the 2-speed gearbox is the possibility to reduce the propeller speed

while the speed of the vessel remains constant in operating conditions where vessel

speed is below maximum. This results in fuel savings of up to 15% when compared to

a single speed mechanical propulsion system. At the same time, nitrogen oxide (NOX)

and sulphur oxide (SOX) emissions are reduced accordingly.

The reduction in fuel consumption and emissions is the result of the

propeller being able to run at close to its optimal design point.

When switching between propeller speeds, both the engine speed and PTO speed

are kept constant, enabling uninterrupted electrical power generation at any time.

Benefits

•   Fuel consumption and exhaust gas emissions reduced

•   Reliable performance with low transmission losses

•   Acts as a systems enabler for vessels with variable operational modes and/or a  

    need for a redundant propulsion system

•   Two selectable propeller speeds at 100% engine speed

•   Provides efficient utilisation of the main engine

•   PTO power at 100% of the engine power

•   PTO power uninterrupted when changing propeller speed

•   Reliable and simple to operate with mode changes from the bridge

•   Lower noise levels for on-board comfort and ecological friendliness

WCP propeller systems

Wärtsilä Controllable Pitch Propeller Systems

Wärtsilä Controllable Pitch (WCP) propeller systems provide excellent performance and

manoeuvrability, and are recommended for vessels with frequent sailing routes that

involve multiple operating conditions. These can be, for example, vessels requiring full

power in both bollard pull and free- sailing conditions, or that make frequent port calls.

WCP propeller systems can also be applicable for vessels that encounter varying

weather conditions or demanding operational requirements, such as dynamic

positioning. A controllable pitch propeller can be the optimal choice for installations

with a shaft generator operating at constant rotational speed. Full propulsion power is

available in both heavy and light conditions through an automatic pitch adjustment.

Engine overload is avoided regardless of the conditions.

The WCP propeller system is the ideal choice for diesel-mechanic propulsion with both

medium-speed and low-speed diesel engines. By integrating a suitable gearbox and

Power Take Off/In, the WCP propeller system can be transformed into a hybrid

propulsion system that enables:

•   High operational efficiency and flexibility

•   A power boost mode

•   Emergency propulsion power.

A Wärtsilä Controllable Pitch (WCP) propeller system comprises a hub, propeller

blades, shafting, hydraulics, control system and any further accessories required. The

system is fully customised to meet the specific needs of the customer. Wärtsilä’s

hydrodynamic experts tailor the propeller for each application to achieve the optimum

balance between fuel consumption and comfort levels, according to the customer’s

wishes.

Technical Data

•   Power range starting from 500 kW, no upper limit

•   4- or 5-bladed propellers starting at a diameter of 1200 mm

•   Bronze or stainless steel propellers

•   Various hub types, depending on the application

•   Compliant with all ice classes.

Options

•   US EPA Vessel General Permit 2013 compliance

•   Zero pollution sterntube

Wärtsilä Hydrodynamic Design

The hydrodynamic design covers propellers for vessels ranging from heavy-duty

ships, such as AHTS to high-speed passenger ferries, and from small fishing boats to

enormous ice classed container vessels. Wärtsilä’s extensive hydrodynamic know-

how is based upon the company’s long history and vast experience in the design of

propellers. Our design tools are continuously developed and validated by a large

number of model test results, full-scale measurements, and research and

development efforts. The latest addition to Wärtsilä’s design capability is the OPTI

Design methodology.

OPTI Design

With OPTI Design the focus is on the vessel’s total propulsive efficiency, which in the

end determines its fuel consumption. This propulsive efficiency depends in turn on the

efficiency of the propeller and the interaction between the propeller and the vessel.

With modern Computational Fluid Dynamics (CFD) it is possible to make a flow

simulation of the complete vessel and propulsion unit. With such simulation, paying

attention to both the propeller design and the details, such as brackets and nozzle

connections and the propulsion unit to the vessel, the overall performance can be

determined. Design features that can be further improved are also revealed, thus

improving the vessel’s overall performance.

Propeller Co., Ltd joint venture company. At this facility fixed pitch propellers with

diameters from 1 to 12 meters and up to 95 tons in weight can be produced. Since

the joint venture company was established in 2004, more than 2000 propellers have

been produced. Furthermore, Wärtsilä CME is able to take advantage of the extensive

experience and databases of LIPS and Wärtsilä with regard to propeller design and

production technology. The propeller and shaft line design tools are based upon long

experience with calculations, model test results, Computational Fluid Dynamics (CFD),

and full scale results.

Propeller efficiency, noise, and vibration requirements are the main considerations for

propeller designs that can be applied for a wide variety of speeds and power

densities, and for any type of ship. The unique Wärtsilä Cunial® propeller material

provides excellent casting, machining and fatigue properties.

Replacement Propellers

By re-designing and replacing existing propellers using Wärtsilä state-of- the-art

design tools, notable efficiency improvements can be achieved. For example, by

designing a Fixed Pitch Propeller to accommodate slow steaming at reduced vessel

speed and power levels, efficiency improvements of up to 15% are possible.

Redesigning and replacing propellers is not restricted to Wärtsilä Propulsion products

only!

Wärtsilä Built-Up Propellers

The Wärtsilä Built-Up Propeller (BUP) is an attractive alternative for a monobloc

propeller. The easily (de)mountable blades and the possibility of under water

(de)mounting enable the propeller blades to be replaced or repaired with minimum

interruption to the normal operating service.

The BUPs are supplied in stainless steel or bronze. Connections to the propeller shaft

are made using a flange and fit bolts. Most BUPs are delivered with 4- and 5-blade

propellers, but 6-bladed propellers can also be delivered on request. There are no

propeller diameter or weight limits. The flush and compact hub design in combination

with efficiency optimised propeller blades makes the BUP fit for applications where low

fuel consumption is important.

Built-up propellers are typically installed on ice-breakers and offshore patrol vessels

operating in heavy ice conditions, or conditions where there is an increased risk of

damage to the propeller. Extended scheduling interruptions are avoided thanks to

rapid (underwater) replacement of the blades.

The short replacement time needed also benefits vessels with a fixed operating

schedule, such as cruise and ferries.

Coastal and Inland Waterway Propellers

Coastal and inland propulsion systems are specialized for vessels operating on local

waterways, and for coastal and fishing vessels. Wärtsilä has considerable expertise in

designing propulsion systems for large, fast luxury yachts and government-owned

ships as well as a variety of special vessels, all with their own characteristics. Wärtsilä

supplies fixed pitch propellers, nozzles, and propeller shaft assemblies complete with

sterntube systems as part of the propulsion equipment for such vessels.

Coastal and Inland Waterway Propellers are available in bronze or stainless steel. They

are tailor-made with 3, 4, 5, 6 or 7 blades. The accuracy can be according to ISO

class II, I or S. Wärtsilä has the capability to deliver fixed pitch propellers for any

diameter above 1000 mm, although for the coastal and inland waterway segment they

are seldom larger than 3500 mm.

52
Propulsors & Gears

Nozzles and Rudders

Wärtsilä High Performance Nozzle

Fitting a nozzle increases the thrust at relatively low ship speeds. This allows for

significant savings to be achieved in terms of fuel consumption, depending on the

number of revolutions and the capacity of the engine. The improved Wärtsilä High

Performance nozzle, the type HP nozzle, when combined with Wärtsilä propellers, can

provide up to 5% more thrust than conventional nozzles in bollard pull conditions. The

nozzle profile offers a double profiled cross section at the inlet side of the nozzle.

Wärtsilä EnergoPac

EnergoPac is the optimised propulsion and manoeuvring solution for coastal and

ocean going vessels. The key objective is to reduce the vessel’s fuel consumption by

integrating the design of both the propeller and rudder. Each EnergoPac is designed

to fit the intended vessel and to meet its specific requirements; this allows EnergoPac

to be optimised fully for energy efficiency, whilst not compromising on either

manoeuvrability or comfort levels.

•   Improved propulsive energy efficiency

•   Reduced fuel consumption

•   Excellent maneuverability

•   Lower vibration levels and higher on-board comfort

•   Reduced levels of emissions

•   Integrated propeller and rudder design.

53
Propulsors & Gears

Nozzles and Rudders

Fuel savings

EnergoPac reduces fuel consumption because it effectively reduces the flow

separation behind the propeller hub. Extended studies show that for the same

course-keeping capabilities, EnergoPac will create less drag than conventional rudder

systems.

Typical applications

EnergoPac can effectively reduce the operational costs for any vessel with a

considerable share of free sailing time in its operational profile. It works 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 Ro-Ro

vessels, ferries, container/multipurpose vessels, and vessels with an ice class

notation. In addition to controllable pitch propeller applications, EnergoPac can also

be applied on vessels with fixed pitch propellers.

Cost savings

The reduction in fuel consumption depends very much on the vessel type, its

operational profile, and 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, its operational profile and other factors. Proven savings in the power required

for a vessel’s trial speed vary between 2 and 9% with EnergoPac.

54

Energy Saving Devices

EnergoProFin

The Wärtsilä EnergoProFin is an energy saving propeller cap with fins that rotate

together with the propeller. It improves propulsive efficiency by weakening the hub

vortex, and by recovering kinetic energy from the rotating flow aft of the propeller

blades. This solution provides average fuel savings of 2%, with a payback time of less

than one year. The Wärtsilä EnergoProFin can be applied for both Controllable and

Fixed Pitch Propellers. Vessels utilising EnergoProFin receive 23 percent discount on

harbour dues at Port of Vancouver.

EnergoFlow

The Wärtsilä EnergoFlow is an innovative and cost-effective pre-swirl stator, that

creates optimal inflow for the propeller by guiding one side of the stern flow in the

opposite direction to the propeller rotation, generating pre-swirl. The EnergoFlow

consists of multiple curved fins and a ring attached to the ship’s hull to prevent the

power losses that typically occur in a propeller’s slipstream. The curved fins enhance

the propeller’s efficiency while keeping resistance at acceptable levels. Hence, optimal

total efficiency is achieved by combined design of the Wärtsilä propeller and

EnergoFlow shape.

The power savings that can be achieved with EnergoFlow varies, depending on the

specifics of each case. Nevertheless, indications are depicted in the illustration above,

based on ship type. Bulk carriers can achieve the highest fuel savings, in the range of

10%. Faster vessels which are already relatively efficient in propulsion terms, could

still see a respectable 4% improvement. Regardless of ship type, Wärtsilä EnergoFlow

typically pays for itself within one to two years.

Steerable Thrusters

Wärtsilä Steerable Thrusters

Wärtsilä steerable thrusters are available in different series covering a wide range of

customer needs. Specific configurations, such as the retractable thruster and

underwater mountable thruster series, are based on the reliable designs of the

standard steerable thruster series. Together they form a steerable thruster range that

covers the most advanced ship design options.

The Wärtsilä Thruster series:

Wärtsilä Steerable Thrusters

The Wärtsilä Steerable Thruster (WST) series is intended for tug or offshore support

vessel applications, and for river/inland waterway vessels. These thrusters have a light

ice class capability and can be combined with high- speed engines of up to 1800

rpm. Two nozzle types can be selected depending on customer requirements: a

bollard pull nozzle or a nozzle optimised for free-sailing.

Wärtsilä Retractable Thrusters

Retractable thrusters provide additional manoeuvring and station keeping capabilities.

The thruster can be fully retracted in the hull for transit or shallow draught operation.

Wärtsilä Retractable Thrusters are available at power ratings up to 6500 kW.

Retractable thrusters up to 4500 kW are available in L- and Z-drive configuration.    

All WST-R feature an 8° tilted propeller gearbox design to minimize thruster-hull and

thruster-thruster interactions. LMT types are equipped with a 3° tilted nozzle.

The small footprint and low weight make the WST-24R and WST-32R the ideal

selection for shuttle tankers.

All retractable types can be fitted with a hull closing plate.

The top of the retractable thruster range is covered by the WST-65RU. This is a

retractable underwater mountable thruster, whereby the outboard part can be

exchanged under water to optimise maintenance when docking of the vessel is not

possible. The underwater mountable part is exchangeable with the WST-65U

underwater mountable thruster.

Wärtsilä Underwater Mountable Thrusters

The Wärtsilä WST-U designated underwater mountable thrusters belong to a series

with several added features, such as an increased power range, an 8° tilted propeller

gearbox, and the Wärtsilä Thruster Nozzle to provide superior and reliable DP

performance. The underwater mountable thrusters from the LMT series are available

for the lower end of the power range.

Special Thruster Designs

Based on the above mentioned thruster series, special thruster designs are available,

such as inboard demountables, icepods and containerized (retractable) thrusters.

Wärtsilä Modular Waterjets

The Wärtsilä WXJ modular waterjets represent the state-of-the-art in this field,

delivering outstanding benefits and performance and offering a high- level of

customisation with a wide variety of options available depending on the vessel type.

The Wärtsilä WXJ series features an improved axial pump design, which boosts

performance with an increased thrust of as much as 3 percent, while the improved

cavitation margins help reduce the environmental impact by lowering noise levels. This

axial pump design comes with a 25% reduction in mounting flange diameter, 10%

overall weight reduction and a 35% increase in cavitation margin compared to its

predecessor, the “LJ type” with a mixed flow pump design, while the small transom

interface dimensions, and best in class weight are unchanged.

Key benefits

Wärtsilä axial waterjets are single stage, compact, high performance systems that

combine mixed flow properties with an axial construction

69
Propulsors & Gears

Waterjets

This results in much less space being needed on the vessel’s transom, and greatly

increased waterjet cavitation margins for optimum vessel operational flexibility. For

naval architects, the axial jet technology creates the possibility to apply a larger power

density onto narrower hulls in order to achieve top vessel performance.

•   Lowest size to weight ratio in the market

•   Axial pump design means less space on the transom

•   Worldwide availability, including China, Japan, Korea, etc.

Waterjets

Waterjet size selection

The selection graphs indicate the jet size required based on the relation between the

vessel’s engine power and design speed. 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.

To ensure an optimised propulsion system for your vessel, we recommend that you

contact Wärtsilä during the early stages of the design work. Please contact us for an

optimised jet selection based on specific vessel design parameters, the operational

profile, or for details of waterjets above 50 knots or 30 000 kW. DXF/DWG format

general arrangement drawings of the most often used sizes are available.

Applications

The characteristics of a waterjet make it a good propulsor for several types of

applications.

•   High speed vessels; waterjets have better propulsion efficiency at ship speeds

     over 25–30 knots.

•   Shallow draft vessels; the integrated steering function provides benefits for

     rescue vessels, inshore passenger ferries, landing crafts & special work boats.

•   High power density; the pressure built-up in the waterjet inlet allows small

     dimensions.

•   Maneuverability; waterjets have integrated steering and reversing with quick

     response capability.

Control Systems

Wärtsilä Protouch Propulsion Control System

The Wärtsilä Propulsion Control System (PCS) is a comprehensive system of levers

and touch-screen interfaces, designed to suit all the possible propulsion

configurations of a modern ship.

Wärtsilä ProTouch, represents the state-of-the-art answer to demands for safe,

intuitive and compact design controls. ProTouch gives the power to the user.

Key benefits

Compact design: The entire footprint of the system is significantly reduced to allow

ergonomic optimisation, and to meet functional requirements.

Modularity/flexibility: The extended modularity of the hardware and graphic user

interfaces provides a flexible solution for any vessel layout. The system fits all the

propulsion products and, as a result, all types of vessels.

74
Propulsors & Gears

Control Systems

Safety: the system improves safety, both at sea and in port, by removing the visual

challenge of finding critical information. It provides the user the relevant information

when needed.

User friendly, intuitive operations: Thanks to the modern displays with

touchscreen technology, the operator has handy access to all functions and

information. The system will guide the user when a more complex sequence or action

is required. Furthermore, the system can support any language.

Simpler installation and maintenance: The system minimizes installation time and

costs, simplifies commissioning, and reduces maintenance needs. This is because the

PCS is fully pre-configurable and the components communicate by a redundant field

bus with a minimal number of cables.

Integration with other systems: The system enables easy integration via serial

interfaces with, for example, VDR, IAMCS and DP/AP systems.

Diesel-electric Propulsion

Wärtsilä is fully aligned with the growing trend in the market for dieselelectric propulsion

systems. Frequency converter fed propulsion systems offer advantages for ships with

the following special requirements in the 400 kW up to 30 MW power range:

•   Low noise and vibration

•   High redundancy

•   Maximum payload capacity and optimal utilisation of available space

•   Economical operation

•   Essential higher reliability, dependability and availability

•   Flexible use of the torque speed characteristic

•   Excellent dynamic characteristics

•   High quality mains

•   Reduced emissions

•   High degree in automation including remote maintenance

•   Reduced wear and tear

Because of these features, electrical propulsion systems are being used, particularly on

ships with special requirements, such as cruise liners, ferries, cable and pipe layers,

research vessels, icebreakers, multipurpose vessels, patrol boats, supply and rescue

vessels, and LNG tankers.

PWM Converter Systems

PWM converters can be used to supply induction motors, synchronous motors or

permanent magnet motors used for electric propulsion, pumps, compressors, winches

and for drilling operations. These converter systems use power transistors in the motor

inverter and can be configured with either a 6, 12, 18 or 24 pulse rectifier front end, or

an active front end inverter which allows regeneration and can also remove the need

for transformers and a braking resistor.

76
Electric Propulsion

Electric Propulsion

Furthermore, these can be configured into the Wärtsilä Low Loss Concept topology, or

as a DC-Hub with a common DC link.

DC-Hub Systems

For inverters connected to the same DC link, the electronic DC breakers work

independently of each other. The multi-drive system connects to the main grid through

either active or diode rectifiers, or can be harnessed to DC sources such as batteries,

solar panels or fuel cells. The system allows electrical operation with variable speed

engines.

LCI Converter System

Frequency converters with line controlled inverters (LCI = synchroconverters) are

designed with direct current (DC) intermediate circuits. They comprise thyristor

rectifiers on the mains side and a thyristor inverter on the motor side. LCI converters

are available for supplying synchronous motors in the high power ranges.

Low Loss Concept

Harmonic voltage distortion causes disturbances for the network and loads, and

impairs the performance of the vessel. By reducing these to a minimum, the Total

Harmonic Distortion (THD) has no influence on the vessel’s operations. Wärtsilä

reduces THD by splitting the distribution bus into two sections, and placing the

transformer between the two buses = Low Loss Concept (LLC).

This means that fewer transformers are needed for installations with more than 2 x

drive power output connected. Where more than 2 x drives are installed, the

advantage of having fewer transformers becomes even more important. In some

installations, the installed transformer capacity is reduced by more than 75%.

The design of the LLC also improves system redundancy. This means that in the case

of failure in one of the switchboards, the drive can continue to operate – albeit with

reduced power.

Wärtsilä HY

Wärtsilä has leveraged its technological leadership in both engines and electrical &

automation to develop Wärtsilä HY, a new-generation integrated hybrid power module.

The various components are tuned and harmonized into a single entity through the

enhanced Energy Management System. Full control over all the hardware and software

enables Wärtsilä HY to be approached as a unified product during engineering, testing

and its operational life.

In order to match the specific demands of different market segments, Wärtsilä HY

comes in highly customizable forms: it is tailor-designed for individual vessel market

segments and can be optimized for specific operating profiles, even throughout the

vessel lifecycle.

The algorithms embedded in the Wärtsilä HY Energy Management

System enable smart features, such as:

•   Smokeless operation: the synergy between the energy storage system and the

     engine allows the avoidance of visible smoke emissions under all normal

     conditions

•   Instant load taking: the module is able to react instantly to fast and broad changes

     in the power demand

•   Automatic power back-up: an increased level of safety is reached through

     emergency back-up algorithms and built-in redundancy of the power sources

•   Start & stop: at low loads the power is supplied exclusively by the energy storage

     system until it reaches a pre-set minimum state of charge. At this point the engine

     is automatically activated, providing power to the ship and simultaneously re-

     charging the energy storage system

•   Green mode: when selected by the operator, power is supplied exclusively through

     the energy storage system until the pre-set minimum state of charge is reached

•   Power boost: the engine and energy storage system can supply power at the

     same time, thus enabling an Instant power boost in output;

•   Peak shaving: load fluctuations are absorbed by the energy storage system,

     allowing stable operation of the machinery.

Wärtsilä Zero

Wärtsilä Zero is an innovative utilisation of alternative energy carriers through emission

free or carbon neutral fuels. Energy storage systems such as electrical batteries,

supercapacitors or hydrogen can be used to achieve a clean energy system onboard.

Wärtsilä has developed solutions for harvesting renewable energy from shore through

an innovative fast charging solution or shore connection system for pure electric energy

storage driven vessels.

Wärtsilä has developed power modules capable of utilising electrically charged

batteries in combination with supercapacitors and/or fuel cells that when driven by

hydrogen or other green fuels offer an emission free solution. The fuel cells can also be

driven by LNG or similar energy carriers, thereby obtaining a cleaner energy system

solution than most other alternatives.

For certain applications the combination of batteries and supercapacitors

achieve an even greater solution for special operations.

HY Upgrade

Hybrid solutions are not only for new build vessels. Existing ships can be retrofitted to

benefit from the multiple advantages offered by Wärtsilä’s advanced hybrid technology.

Wärtsilä completed its first hybrid conversion project already in 2014. The ‘Viking

Lady’, a platform supply vessel owned by Eidesvik Offshore, was fitted with a Wärtsilä

Low Loss Hybrid system, after which a comprehensive measurement program

confirmed fuel savings of 15%. Less fuel burned also means fewer exhaust emissions.

When in transit mode in heavy weather conditions, the ‘Viking Lady’ uses the battery

to reduce frequent load variations on the engines. This allows one less genset to be

used because a higher average load can be maintained. In critical operations, the

battery is used as power redundancy while a charge / discharge strategy is also

adopted. This allows one engine and a single battery to operate at the most efficient

loading.

Hybrid Energy Storage Systems (ESS)

The Hybrid Power System combines different power sources with energy storage

devices. The introduction of the hybrid power system, and its integration with

conventional diesel or dual-fuel engine generating sets, offers a significant

improvement in efficiency by running the engines on optimal load and absorbing many

of the load fluctuations through batteries.

The introduction of Hybrid Power Systems with energy storage is a new and attractive

way of reducing both fuel consumption and exhaust emissions. Utilising the latest

wireless charging technology, Wärtsilä can offer total electrical plug-in solutions and

completely integrated vessel design concepts.

Wärtsilä’s system design incorporates energy storage capabilities in the form of battery

packs, hybrid control systems, power transfer systems, and energy storage systems.

Fuel saving and reduced emissions

Less fuel consumption ensures a substantial reduction in emissions, and supports

sustainable operations with different fuels. Annual fuel savings have proven to be

between 10-20%, depending on the type and configuration of the engines.

Optimised engine operation

By optimising performance, the engines can be operated with optimal specific fuel

consumption.

Reduced engine transients

Wärtsilä’s ESS reduces transient loads in engines. Transients increase both fuel

consumption and emissions.

Hybrid Control System

The Wärtsilä Hybrid Control System controls and monitors the overall operation of the

battery system, which includes:

•   Charging and discharging of batteries taking into account battery characteristics.

•   Versatile control for Battery (Power) and Battery (Safety) notations.

•   Control strategies to optimise the performance and reduce the transient loads of

•   Grid support for black out prevention.

•   Interface to vessel PMS and IAS systems.

Engine peak shaving in combined battery and engine modes is a configuration

whereby the batteries take the load required to run the thrusters, while the engine is

running with a stable load profile.

Hybrid Propulsion

Hybrid Propulsion

Increased redundancy and efficient operations

Power redundancy needs require engines to run at low loads. With the battery

providing the redundant power, the engine can operate more efficiently at higher loads.

Reduced maintenance

Thanks to more stable operations and reduced engine running hours, maintenance

costs will be lowered.

Better performance

The fast power response from the energy storage system means that vessel

performance will also be more responsive. This may also increase dynamic

performance in critical operations.

Wärtsilä Smart Energy Management

Optimisation of power generation, energy consumption and energy storage in a vessel

by utilising digital technologies comprises predictive energy management, Smart

propulsion, optimised energy efficiency, and hotel load and cargo energy efficiency with

Smart service loads. Voyage planning will secure the best route efficiency.

Energy control and optimisation of the complete vessel energy systems are achieved

throughout the vessel by implementing solutions such as the Energy management and

Hybrid control system to manage and operate the Propulsion and Power electric

systems onboard. Optimisations of various components increase reliability even further:

Engine and power supply, Electrical power conversion systems, Propulsion controls,

Waste

heat recovery, Energy storage systems (e.g. batteries), fuel cells, solar panels and

Power transfer systems to/from shore.

Wärtsilä has implemented Energy optimisation on different levels of vessel

management: Energy management by selection of sources and controlling consumers

of energy. Power management, Stop/start and control, as well as Power electrical

system control, synchronisation, AVRs, and load sharing, including Power electrical

system protection (frequency, current, voltage, breakers).

Wärtsilä Smart Energy Management is an onboard energy optimisation

and control solution that also comprises solutions related to fleet

management, lifetime services and maintenance systems.

Power Generation

Power Generation

Shaft Generator Systems – PTO/PTI/PTH Applications

Wärtsilä provides Shaft Generators (SG), driven by the main engine to supply power to

the mains within the 500 kW to 9000 kW range. The power generation has to function

properly at changing propulsion shaft speeds, when the ship travels at different

speeds, or in the case of very fast speed changes caused by heavy seas. To allow a

stable frequency and voltage in the mains while the main engine speed is changing – a

frequency converter with PWM technology is used.

Using shaft generators is a particularly economical and environmentally

friendly method of generating electrical power. For this reason, more

and more ships are being equipped with such systems. The use of shaft

generators provides many advantages:

•   Reduced maintenance costs

•   Lower fuel and lubrication costs

•   Fast return on investment (down to 3 Years)

•   Added safety for ship and crew

•   Low noise power generation

•   Smaller or fewer diesel generator sets

•   Continuous parallel operation together (two SG systems) or with diesel generator

     sets

On ships with fixed pitch propellers, the speed is set via the propeller speed. If using

controllable pitch propellers, the shaft speed and the propeller pitch are adjusted

84
Power Generation

Power Generation

simultaneously in order to achieve optimum propeller efficiency in this so-called

combinator mode. Even with this type of propeller, it is nevertheless economical to use

shaft generator systems with a frequency converter for variable speeds in order to

enable a combinatory mode from pier to pier.

•   Unrestricted operation during main engine speed variations resulting from heavy

     seas and manoeuvring

•   Continuous parallel operation together (if 2 shaft generator systems are provided)

     and with diesel generator sets

•   Generation of the required active power and reactive power

•   Selective tripping of short circuits without failure of the overall system

•   Starting and shut-down of large consumers without inadmissible voltage and

     frequency fluctuations

•   Operation, including synchronisation, in the same way and with the

     same operating controls as with diesel generator sets

•   Simple integration in automated power generation systems

For applications in combination with exhaust-gas and steam turbine generators,

PTI/PTO shaft generator systems with a power range of 3.6 MW to 9.0 MW with 6.6

kV are required. They are also required for lower power demand with high redundancy

of the propulsion system, PTI/PTH/PTO SG. Systems including power take home drive

are possible with LV and MV applications.

85

Wärtsilä Shore Connect

Wärtsilä helps ship operators and port authorities to meet increasingly stringent
environmental regulations by enabling ships to meet their electrical power
requirements, even when the engines are shut down. By taking the power from the
shore, instead of from the engines, there are no exhaust emissions or noise pollution.
Through its Shore Connect solution, Wärtsilä provides the technology to make this
possible.

Alternative Marine Power – High Voltage Wärtsilä Shore Connect

The system design is essentially based on meeting port needs while also conforming

to ICE/ISO/IEEE 80005-1 requirements. A typical configuration comprises the key

components, such as the cable reel, a medium voltage switchboard, and a control

and monitoring facility that includes an interface between ship and shore. A

complete assembly can either be installed separately on-board the vessel, or

containerised for siting at a specific on- board location. Upon request, we can

develop tailor-made solutions for all vessel types. We offer the full range of turnkey

integration options.

The value of Lifecycle Solutions

Digitalisation and connectivity enables a full range of new services but data is not
enough in itself to generate improvements. Creating value requires analytics and
technical experts who can make sense of the data and give actionable advice.
Wärtsilä Expertise Centres around the world have this expertise to support, predict
and optimise your asset performance. In practice, this is done through services such
as Expert Insight, Operational Support and Data Driven Maintenance which are
available as part of the Wärtsilä Lifecycle Solutions agreements.

Expert Insight – improved reliability through early detection

The Expert Insight takes predictive maintenance to the next level by utilising artificial
intelligence and advanced diagnostics. Expert Insight analyses asset data according to
a set of rules based on Wärtsilä’s vast installed base, and artificial intelligence is used
to model asset behaviour. Should anomalous asset behaviour occur and be detected,
it is flagged to specialists at Wärtsilä Expertise Centres, allowing them to support the
customer proactively with an appropriate resolution to the issue. The combination of
AI, advanced diagnostics, and the company’s extensive equipment expertise greatly
enhances the reliability, efficiency, and safety of the installed equipment. 

94
Lifecycle Services

Data Driven Maintenance – a more flexible approach to maintenance

With Data Driven Maintenance the idea is to take a condition-based approach to


maintenance rather than adhering to a fixed overhaul schedule based on logged
running hours and infrequent reporting. By monitoring the critical engine parameters in
real time it’s possible to extend the time between overhauls and eliminate the need for
some time-consuming, costly intermediate interventions. Data Driven Maintenance is
delivered as part of Wärtsilä Optimised Maintenance and Wärtsilä Guaranteed Asset
performance solutions, with various service levels that can be tailored according to the
customers' business needs.

Wärtsilä Expertise Centres – serving you wherever you are

Lifecycle Solutions agreement customers are served by our 10 Wärtsilä Expertise


Centres around the world. Dedicated experts who are familiar with your vessel’s
operations provide round-the-clock expert support whenever needed. This includes
remote investigation and troubleshooting support, actionable advice and remote
guidance for technical site operations, ensuring any issues are resolved as quickly as
possible and reducing the need for unscheduled maintenance actions and visits.
