at Wärtsilä, we are passionate about optimising lifecycle value by delivering whatever you need from the most complete off ering of products, solutions and services in the marine industry. Here’s what we can do. let’s fi nd your route to bigger profi ts.

The fi rst step is to fi nd out exactly what you need and how we can serve your interests best. Our multi-disciplinary skills are at your service to establish the specifi cs of your requirements.

Construction is easier when you can get everything from a single supplier. Wärtsilä is the only true one-stop shop for shipyards. In addition to the vessel’s design, we can provide the services of an experienced systems integrator.

Such integration is essential to avoid added risk and building delays. The choice of a single supplier for the design, engineering and systems integration of the main equipment will ensure an optimised solution. This also off ers better risk control during the new building phase.

Effi cient engines are probably what we are best known for. Over the decades we’ve extended our off ering to improve the effi ciency of all marine solutions. And when the systems are more effi cient, you also produce fewer emissions. Our environmental solutions ensure that you can operate profi tably in Emission Controlled Areas – both Tiers II and III.

Whether we are delivering one small spare part or a total lifecycle solution, we understand that it’s all about safety, reliability and the total cost of ownership.

Sometimes, a new vessel is the best solution. And sometimes upgrading or converting an existing vessel is the better way to go.

Our designs fall into three categories:

Customised designs that meet the most rigorous challenges

Integrated designs that combine the best of our design and equipment knowledge

Proven designs that add value

These designs can rely exclusively on parts from the Wärtsilä off ering or we can, for example, use engines or equipment made by someone else. It’s about whatever best serves your specifi c needs.

Wärtsilä’s project management and site supervision teams have the competences, methods and systems to ensure on time delivery. Together we can minimise both the cost of construction and the project completion risks.

By utilizing Wärtsilä’s optimisation services, the life of your vessel is extended and its

market value is enhanced.

cargo control system upgrades commissioning/iMO certifi cation assistance process tuning for energy consumption Troubleshooting/pre-docking inspections

By signing a service agreement that fi ts your needs, you pay only for what

is necessary. Our service personnel are dedicated to preventing the

unexpected, ensuring environmental compliance, increasing effi ciency,

and making sure that your operations remain optimal. With our global

service network, help is always close at hand, wherever you are.

We upgrade vessels to meet environmental regulations and are a global leader in lng conversions. We also perform upgrades to increase overall effi ciency, or to adapt the ship to a new operating profi le. We place special emphasis on dynamic maintenance planning to maximise your vessel’s lifecycle value.

Our gas technology is in a class of its own, with an unparalleled track record of over 6,000,000 (and counting) hours of operation already logged.

STHe naTURal cHOice

Natural gas is the cleanest fossil fuel in the

world. At Wärtsilä, we have for several decades

pioneered the development of natural-gas-

based power. With our gas-fuelled solutions, the

combination of high effi ciency and low emissions

is now unequalled in the marine market.

readY for the fUtUre

Our product portfolio meets the strictest

requirements of today and continues to rapidly

evolve to match those of the future.

Switching from HFO to natural gas

reduces all important exhaust gas emissions,

including a 30% reduction in CO2 and 85% fewer

NOX emissions. SOX emissions are eliminated

altogether and the particulate emissions are very

low. Furthermore, there are no sludge deposits or

visible smoke. With gas, the stricter environmental

rules to be applied in all SECA areas in 2015 can

thus be met with fl ying colours – already today.

the power to choose

Wärtsilä is a world leader in dual-fuel systems

that give you the chance to select the most

suitable fuel or fuels depending on factors such

as availability and price.

Our dual-fuel (DF) engines are unique in the

breadth of their fl exibility. They are able to run on

natural gas, marine diesel oil, heavy fuel oil, or

even on bio fuels. Fuel fl exibility off ers a higher

level of operational safety: If the gas supply is

interrupted, dual-fuel engines instantly switch to

diesel operation without loss in speed or power.

Wärtsilä was also the fi rst to choose the

Otto Cycle for our dual-fuel engines. This decision

proved very successful. Now we have more than

10 years of experience in dual-fuel technology,

with more than a hundred LNG carriers as well

as OSVs and other vessels powered by our gas

technology.

lIQUId cargo handlIng

Through the acquisition of Hamworthy, Wärtsilä

is now also a leading supplier of gas carrier

cargo handling technology, as well as key cargo

handling equipment. Our extensive experience

with cargo systems for LPG, ethylene and LNG

handling forms the basis for supplying new

solutions in an ever expanding technically driven

environment. Instead of using boil-off gas as fuel,

as was done earlier, our reliquefaction systems

liquefy the boil-off gas and return the LNG back

to the cargo tanks. This results in an increased

quantity of cargo delivered, large savings in

total fuel consumption, and improved propulsion

redundancy.

welcome to the gas age

Gas is clearly the environmentally superior

choice – and is also often viably priced,

especially when such benefi ts as fl exibility and

longer maintenance cycles are factored in. It

is not surprising, therefore, that gas engines

are becoming increasingly the choice for both

newbuild vessels and ship conversions.

Wärtsilä off ers a well-integrated, safe and

smooth transition to the new gas age.

6 7

Using natural gas as fuel

reduces both exhaust gas

emissions and operating costs,

making it an attractive option

for shipowners and operators.

Dual-fuel engines in gas mode

produce 25% less CO2, 85%

less NOX , and practically zero

SOX and particles.

AS

Wärtsilä has supplied propulsion machinery for

the new M/S Viking Grace passenger ferry built

for Viking Line at the STX Finland shipyard in

Turku. The vessel entered service at the beginning

of 2013 and operates on the Baltic Sea between

Turku and Stockholm.

Increased passenger comfort

Thanks to the propellers generating the lowest

possible pressure impulses, the vibration

level in the stern hull is very low. Wärtsilä also

supplied a sound-absorbing system to minimise

noise generated by the engine, thus increasing

passenger comfort. Since the vessel’s route takes

it through the local archipelago, the low noise

level reduces the impact to the islands’ residents.

clean and strong

Wärtsilä’s dual-fuel technology enables the vessel

to operate without restrictions in the SECA and

NECA sulphur and nitrogen monitoring areas.

The Viking Grace is capable of carrying cars,

trucks and road trailers on short international

voyages. The construction of the machinery,

equipment, outfitting and structure has been

monitored by the Lloyd’s Register of Shipping

classification society.

growIng together

Viking Line and Wärtsilä have for a long time

successfully co-operated on ship propulsion

systems. Over the years Wärtsilä has been the

main supplier of diesel engines for Viking Line’s

new vessels.

– It is in our best interests to co-operate

with Wärtsilä, since they are experts in the

development of new types of engines, the use of

alternative fuels, low specific fuel consumption

and environmentally safe operation. Wärtsilä is a

domestic supplier close to us and offers us the

opportunity to collaborate on operational matters,

engine maintenance, technical training and field

testing. All this is very important, especially now

that Viking Line is entering a new era of gas-

electric driven operation, says Tony Öhman,

Technical Director in charge of Marine Operations

and Newbuilding at Viking Line.

Wärtsilä Hamworthy delivered three LNG

regasification skids that were used to convert the

2004-built LNG carrier Golar Winter into an LNG

floating storage and regasification unit (FSRU)

by Keppel Shipyard, Singapore. The 138,000 m3

vessel is chartered by Petrobras in Brazil, where

the gas will be sent from the Golar Winter to an

onshore gas grid through a subsea pipeline.

The new technology is based on an

intermediate closed propane loop that uses

seawater as the heating medium for vaporising

LNG. The intermediate propane circuit between

the seawater and the LNG is applied to avoid

freezing. As it uses seawater, the system is

extremely efficient and requires less fuel, which

is less expensive than steam-based systems for

regasifying the LNG. The equipment is designed

for marine installations and cryogenic working

conditions, and can handle large variations in

send-out capacity.

In addition to the Golar Winter, Wärtsilä

Hamworthy also supplied the regasification skids

for the 1977-built LNG carrier Golar Freeze,

which was converted into an FRSU. It has been

chartered to Dubai Supply Authority and moored

permanently alongside a purpose-built jetty within

the Jebel airport.

from desIgn featUres to operatIonal measUres

At Wärtsilä we optimise a vessel’s effi ciency by

looking at the whole picture, starting from the

initial design. We study its power and propulsion

systems, the integrated automation systems,

and the way that the vessel will be operated and

maintained.

We look at the overall dimensions, the hull

and appendages, and the total concept of the

ship, hull and appendage design, and total ship

concepts. Substantial savings in operational costs

can easily be achieved if all these items are taken

into consideration from the beginning of the ship

design process.

Propulsion includes propulsion concepts,

propeller hull interaction and propeller design,

and also takes into account alternative solutions

such as wind power. New concepts in particular

can result in great power savings. The rapidly

evolving tools for fl uid dynamics have also given

us a much greater understanding of the physics

behind design optimisation.

When selecting the optimal power system,

you might consider the machinery concept,

such as electric and hybrid confi gurations,

heat recovery, alternative fuels, as well as

the automation and controls. By tailoring the

machinery concept to match the operating

profi le, fuel consumption can be notably reduced.

Additionally, waste heat recovery can generate

large energy savings and has great future

potential.

We work closely with our customers taking

into consideration also how the ship will be

operated, including time in port, voyage planning

and speed reductions. We off er full maintenance

and servicing of the vessel, such as hull and

propeller cleaning, automation adjustments, and

condition-based maintenance programmes. By

combining all of these items, and treating them

jointly, an integrated and more truly effi cient ship

operation can be achieved.

Wärtsilä has the ability to offer total concept

solutions that include the design of the vessel,

the propulsion plant, and the electrical and

automation system, as well as a host of fuel

saving and environmentally sustainable options.

The Viking Prince, running on

environmentally friendly LNG dual-fuel engines,

entered service in March 2012. The vessel is a

Wärtsilä VS 489 Gas PSV design and features

excellent energy efficiency, a unique hull

form, fuel flexibility, and outstanding vessel

performance in areas such as fuel economy and

cargo capacity.

All Eidesvik’s gas PSVs are designed by

Wärtsilä and utilize Wärtsilä’s unique dual-

fuel technology. Wärtsilä’s scope of supply for

Viking Prince includes dual-fuel main engines

and generating sets, the electrical power and

propulsion system, integrated automation, and the

power management system. The vessel is fitted

for use in arctic waters with ‘winterization’ and

de-icing solutions.

Wärtsilä supplies full propulsion systems with

Wärtsilä closed loop scrubber systems for a series of

eight vessels, with an option for another two, being

built for Algoma Central Corporation to transport bulk

commodities on North America’s Great Lakes and

St. Lawrence Seaway. The first vessel - the ‘Algoma

Equinox’ was launched in December 2012.

The full propulsion system with Wärtsilä’s

closed loop scrubber systems lowers operating

costs while reducing the vessel’s environmental

footprint by allowing the owners to use high sulphur

fuels in Emission Control Area (ECA) zones and

still meet sulphur emissions restrictions. Wärtsilä’s

closed loop scrubber systems remove almost 100%

of the sulphur content from the exhaust and 80%

of particulate-matter emissions thus achieving

the 0.1 per cent sulphur emissions standard for

North American ECAs set by the IMO. It also saves

space and weight, preserving the vessel’s cargo

deadweight capacity.

efficient engines, propulsion machinery and a

bilge water separator, designed to reduce oily

residues at source. It features mechanical seals

on all pumps and engineered drainage systems

to capture potential leakage. Any oily residues

that do occur are treated with Wärtsilä’s high-

efficiency Oily Water Separator. Stern tube and

rudder bearings are lubricated with water to

eliminate oil leakage from these sources.

Wärtsilä combines the complete solution

in an optimised way, which results in savings

for the owner and a significantly reduced

environmental footprint. With an extensive

In 2012, Wärtsilä supplied the design and

equipment for a new Platform Supply Vessel (PSV)

built at the shipyard Hellesøy Verft AS and owned

and operated by the Norwegian Vestland Offshore.

In response to the customer’s demand for

a modern, high quality, and fuel-efficient PSV,

Wärtsilä Ship Design developed an extremely

energy efficient and environmentally sound

solution. Based on the well-proven VS 485

design, the new vessel has an optimised hull

design for greater efficiency, which results in

reduced air emissions. It is fitted with our medium

speed engines and a Wärtsilä NOX Reducer, and

also includes four 9-cylinder Wärtsilä 20 diesel

generator sets, the electric propulsion system, the

power management system, and an integrated

automation system.

“Vestland Offshore is building a fleet of vessels

that emphasise energy efficiency, safety,

reliability, and environmental sustainability. These

are all major focus areas for today’s oil industry,

and Wärtsilä’s designs are at the forefront of

achieving these aims.”

Tor østervold

Chairman of the Board, Vestland Offshore

Ignazio Messina’s vessel ‘Jolly Diamante’ was

the first ever vessel to operate commercially with

an exhaust gas cleaning system when it entered

service in December 2011. Wärtsilä’s hybrid

exhaust gas cleaning system not only ensures

universal compliance with sulphur limits, allowing

maximum choice over voyage routes and

destinations, but also allows significant flexibility

in the operation of the system itself.

The hybrid approach allows switching

between the open loop and closed loop systems,

enabling only seawater to be used at sea and

recirculation of the water whilst the loop is

closed for use whilst manoeuvring or in port. The

Wärtsilä system on the Jolly Diamante has also

been optimised to ensure energy efficiency under

all conditions.

It is the first of four new 45,000 dwt ro-ro

ships for Ignazio Messina & Co being built with

a Wärtsilä hybrid exhaust gas cleaning system,

enabling each vessel to meet 0.1% sulphur

emissions regulations in EU ports, as well as

“future proofing” the vessel for the impending

0.1% Emission Control Area limit in 2015.

Equipment supplied by Wärtsilä also

includes a control system, combined wash-

water treatment plant and a new range of super

duplex stainless steel pumps supplied by Wärtsilä

Hamworthy’s Singapore plant. All emissions will

be continuously monitored.

The product tanker Bit Viking was the fi rst vessel

to undergo a conversion by Wärtsilä from heavy

fuel oil to liquefi ed natural gas (LNG) operation.

This conversion, for Tarbit Shipping, qualifi ed the

Bit Viking for signifi cantly reduced nitrogen oxide

(NOX) emission taxes under the Norwegian NOX fund

scheme. The fund is a cooperative eff ort in which

participating companies may apply for fi nancial

support in return for introducing NOX reducing

measures. Additionally, liquefi ed natural gas (LNG)

operation means lower carbon oxide emissions, and

virtually no sulphur oxide or particle emissions.

The re-commissioned vessel is operated by

Statoil along the Norwegian coastline.

This is the fi rst marine installation in the world

to involve converting Wärtsilä 46 engines to Wärtsilä

50DF dual-fuel engines, and the fi rst Wärtsilä

50DF dual-fuel marine installation with mechanical

propulsion. By operating on LNG, the Bit Viking

becomes one of the most environmentally friendly

product tankers in the world.

“Wärtsilä’s unique expertise and experience with

dual-fuel technology, as well as with fuel conversion

projects, were the main reasons for us choosing
