Wärtsilä power and propulsion solution for Siem Offshore newbuildsVessel & ROV News // November 29, 2012
Wärtsilä has been contracted to supply an integrated solution comprising ship design services and the power and propulsion system for a newbuild LNG powered PSV.
The contract has been signed with the Norwegian yard Hellesøy Verft, and this will be the eighth vessel built at Hellesøy to be based on the Wärtsilä Ship Design VS 485 series. The vessel will be owned and operated by Siem Offshore on a charter contract for TOTAL.
The vessel is of Wärtsilä VS4411 LNG PSV design and features Wärtsilä power and propulsion, electrical and automation systems, including a complete four-split Wärtsilä Low Loss Concept (LLC) solution.
This highly redundant electric power distribution system enables energy-efficiency increases of 2 to 4 percent, reduced electrical losses leading to greater fuel economy, while providing additional reliability for continuous operation. It also improves lifecycle performance and the fully-integrated design significantly reduces integration risks.
The PSV will also be equipped with the Wärtsilä LNGPac LNG storage and handling system.
The PSV is scheduled to be operational from 2014 and will serve the Martin Linge oilfield, North-West of Stavanger, Norway. It has been designed to specifically meet TOTAL's North Sea operational requirements.
"The LNG PSV for Siem Offshore is the ninth to be designed by Wärtsilä Ship Design for LNG PSVs," said Riku-Pekka Hägg, Vice President, Wärtsilä Ship Design.
This will be the first of Siem's vessels to be powered by LNG.
