PSV Power Deal For Wärtsilä

Wärtsilä Corporation today announced it has been contracted to supply ship designs and propulsion systems for three platform supply vessel (PSV) newbuilds.

Last week Ship & Bunker reported Norwegian shipyard Kleven Maritime AS will build the vessels.

Norway based companies Atlantic Offshore will own two ships and Remøy Shipping the third.

According to the press release, the vessels will have an Environmental Rating Number (ERN) of 99.99.99.99, which Wärtsilä says represents their capacity to maintain position and normal operations in certain weather conditions.

Integrated Automation Systems (IAS) will include the Wärtsilä ECOmeter allowing the operator to maximise the vessel's fuel consumption, attain efficiency in track planning, and ensures the efficient running of the generators.

All three vessels will "meet the IMO's most stringent requirements" for NOX emissions.

Wärtsilä said the Remøy's PSV will be the eighth LNG PSV based on Wärtsilä designs.

"The original tender was for seven vessels, and of those, only one was for an LNG fuelled PSV, which Wärtsilä Ship Design was selected for. All in all, Wärtsilä Ship Design won orders for three vessels, which represent a large part of the total order," said Riku-Pekka Hägg, Vice President Wärtsilä Ship Design.

"We are delighted that our proposals were judged to be appropriate and competitive, and that our tenders have been successful," he added.

The PSVs for Atlantic Offshore will feature Wärtsilä power, propulsion, electrical and automation systems, and each will be 90.4 metres in length and based on the Wärtsilä Ship Design VS485 format.

The LNG PSV for Remøy Shipping is a Wärtsilä Ship Design VS4412 DF PSV, and will be 92.5 metres in length.

All three ships will be operated by the partially state owned Norwegian oil and gas company Statoil and will be used to support operations on the Norwegian continental shelf.

Wärtsilä say the designs ensure the vessels can endure the challenging environment in the North Sea, and to accommodate owner and operator capacity, and fuel economy.

Equipment is expected to be delivered in the fall of 2013, with the vessels scheduled to be in operation by the end of 2014.
