Wärtsilä books ship design orders for Statoil PSVs

Remoy PSVJULY 25, 2012 — Wärtsilä has booked ship design orders from shipbuilder Kleven Maritime for three of the new platform supply vessels being built to support Statoil operations on the Norwegian continental shelf.

The vessels include a 92.5 m long VS4412 DF PSV LNG-fueled PSV (pictured at left) for Remøy Shipping. It will operate on liquefied natural gas (LNG) and will be the eighth LNG PSV to be built based on Wärtsilä designs. (See earlier story).

"This significant order speaks highly of Wärtsilä's design capabilities, which are based on the company's deep experience and broad know-how. The original tender was for seven vessels, and of those, only one was for an LNG fueled PSV, which Wärtsilä Ship Design was selected for," said Riku-Pekka Hägg, Vice President Wärtsilä Ship Design.

The two PSVs for Atlantic Offshore are based on the well proven Wärtsilä Ship Design VS485 format and are 90.4 m in length.

The Atlantic Offshore ships will also feature Wärtsilä power and propulsion, electrical and automation systems, including the patented Wärtsilä Low Loss Concept (LLC). The highly redundant diesel-electric system provides additional reliability for continuous operation in various failure modes. The vessels will attain the highest possible Environmental Rating Number (ERN) of, representing their capacity to maintain position and normal operations in certain weather conditions. The Integrated Automation System (IAS) to be delivered will also include the advanced Wärtsilä ECOmeter. This feature allows the operator to be able to optimize the vessel's fuel consumption, and is an efficient tool for track planning, as well as ensuring the most efficient running of the generators. The vessels are also required to meet the IMO's most stringent requirements regarding emissions of NOx.

Wärtsilä's equipment deliveries will begin in autumn 2013, and all three vessels are scheduled to be operational by the end of 2014.
