Wärtsilä is to supply the design and an integrated solution for a new large PSV. The ship, owned by Norwegian offshore services provider Siem Offshore, will operate primarily on LNG.

The new PSV will be operated under charter by A/S Norske Shell and is being built at the Remontowa Shipbuilding's yard in Poland.

Ship Design and LNGPac

The contract's scope of supply includes the Wärtsilä VS 4411 LNG PSV initial, basic, and detailed ship design, as well as the complete diesel electric system with Wärtsilä dual-fuel generating sets, the Wärtsilä LNGPac gas storage and handling system, and the complete electrical and automation system, including a four-split Wärtsilä LLC (Low Loss Concept) solution.

The Wärtsilä LLC will help the vessel fulfil the highest possible Environmental Regularity Number (ERN) of 99.99.99.99, which represents the vessel's capability for maintaining its position and normal operations under certain weather conditions.

The 89.2 metre long vessel is scheduled to commence operations in 2015 and will be used to support offshore drilling and production activities in the North Sea. It can accommodate a crew of 25.

This order follows a similar one placed in November 2012 with the same scope of supply for another Siem Offshore owned PSV.
