Wärtsilä Corporation, Trade & Technical Press release, 1 December 2010

The Mississippi River and other inland rivers of the United States are home to
several thousand towboats. They are vital carriers of goods and materials, and
an important element within the country's overall transportation system. Current
and future environmental restrictions on emissions are creating the need for a
new 'greener' design for these vessels.

Wärtsilä and Ship Architects, Inc., USA, cooperate to develop a new
environmentally sound towboat concept. Ship Architects, Inc. is a company that
specializes in providing shipyards and owners with technical solutions in
conceptual and detailed vessel design, project management, and other associated
services. Wärtsilä is the leader in dual-fuel technology that allows its
propulsion solutions to be operated on a variety of fuel types, including clean
natural gas. The companies have together developed a new concept of towboat
design that employs Wärtsilä 20DF and 34DF dual fuel engines for propulsion.


An industry facing stringent environmental regulations

The riverboat industry is facing challenges as the result of progressively
severe restrictions being imposed on engine emissions. Further reductions will
be needed in the future when the Emissions Control Area (ECA) regulations take
effect in August 2012. There is a sense of urgency to the development of more
environmentally friendly vessels.

Wärtsilä's industry leading dual-fuel technology enables the towboats of US
rivers to be powered by engines that comply with current and future
environmental legislation, while creating operational cost savings for the
operators.

"It has been clear to our company for quite a while that the river towboat
industry is one whose needs match the answers that natural gas provides. With
that in mind, our architects made a conceptual design to create a leading
technology river towboat. It is based on the use of clean LNG as its propulsion
fuel, and we are very pleased for Wärtsilä's co-operation in making this
possible," commented Joe Comer, President of Ship Architects, Inc..


Wärtsilä technology eliminates need for low-sulphur fuel

The key driver to this need for change is the US Environmental Protection
Agency's (EPA) lowering of sulphur content levels in the fuel used. In fact the
EPA's limits are tighter than the global standards, and call for a maximum
sulphur content of just one percent already this year. The bottleneck to the
adoption of these new standards is the limited refining capacity for low-sulphur
fuel. Not only is this creating a shortage of supply, but the demand is also
leading to substantially higher fuel prices, which in turn is impacting the
operational revenues of the operators. Fortunately, the USA is rich in natural
gas resources. This means that natural gas is abundant, secure, available, and
affordable at relatively low prices.

John Hatley, Vice President, Ship Power, Wärtsilä in North America, noted that:
"This is an exciting time of change for the towboat industry, with natural gas
powered engines providing a huge step forward. Wärtsilä is very pleased to be
working to make this key player in America's transportation system, both
'greener' and more economically viable."

The inland river towboats of North America have been built to essentially the
same design for the past 65 years or more. The accepted norms for propulsion,
hull design characteristics, engine, and particularly fuel selection, have
continued unchanged from one decade to the next. That is, until now.
