Wärtsilä successfully tests new 2-stroke dual...

Wärtsilä Corporation, Trade & Technical press release, 23 September 2011


The on-going tests show that the Wärtsilä 2-stroke gas engine performance is in
compliance with the upcoming IMO Tier III NOx emission limits, thereby setting a
new benchmark for low-speed engines running on gas.

Wärtsilä, the marine industry's leading solutions provider, has successfully
tested its new low-speed gas engine technology in trials conducted at the
company's facilities in Trieste, Italy. The tests were carried out on September
19 in conjunction with Wärtsilä's Licensees Conference in Trieste. Wärtsilä
successfully demonstrated that the engine performance fully complies with the
upcoming IMO Tier III nitrogen oxide (NOx) limits, thereby setting a new
benchmark for low-speed engines running on gas.

The new RTX5 2-stroke test engine is part of Wärtsilä's 2-stroke dual-fuel gas
engine technology development programme. This is an important part of the
company's strategy to lower emissions, increase efficiency and to develop its
low-speed engine portfolio to include dual-fuel gas engines alongside its
medium-speed dual-fuel engines.

"The decision to initiate this project was announced in February 2011, just
seven months ago. The fact that we have already conducted a successful test
shows that our gas engine technology is at the forefront of meeting the future
needs of shipping, a future that stipulates more stringent environmental
regulation. This further highlights Wärtsilä's leading in-house know-how,
professional approach and overall competence in this field," says Lars Anderson,
Vice President, Wärtsilä Ship Power Merchant.

The tests with the RTX5 engine will continue during the autumn and winter of
this year, and into 2012. More details about the engine technology and its
performance will be announced upon completion of the programme.

The running of the test during the company's Licensees Conference is significant
in that the company's low-speed engines are produced by specialised engine
manufacturing companies under license. The licensees market, manufacture and
sell the engines under agreed conditions. Wärtsilä has established a world-wide
network of 19 licensees for manufacturing 2-stroke engines. These are located
mainly in Asia (Japan, Korea, China, Vietnam), but also in Europe (Croatia,
Poland and Russia) and South America (Brazil).


Reducing environmental footprint with LNG

Environmental regulations are becoming increasingly stringent. The IMO's
(International Maritime Organization) Tier III regulations, which will come into
force in 2016, stipulate that NOx (nitrogen oxides) emissions must be cut by 80
per cent compared to the IMO Tier I levels.

The use of liquefied natural gas (LNG) as a marine fuel is widely seen as being
the most realistic means of reducing the marine industry's environmental
footprint. When operating in gas mode, vessel emissions of nitrogen oxide (NOx),
sulphur oxide (SOx), carbon dioxide (CO2), and particle matter are heavily
reduced. At the same time, LNG fuel is often found to be more competitively
priced than conventional liquid fuels, thus enabling ship owners and operators
to achieve important operational cost savings.

Wärtsilä has more than 40 years of experience in gas engine applications for the
marine sector. However, the real breakthrough came with the introduction of the
company's dual-fuel engine technology in the mid 1990s. Today, Wärtsilä is the
recognized global leader in gas engine applications for both the marine and
power plant industries. Wärtsilä has also recently announced that its dual-fuel
medium speed engines have exceeded three million running hours in both land-
based and marine applications. This milestone represents a dual-fuel technology
track record that cannot be matched by any other engine manufacturer.
