Another LNG platform supply vessel win for Wärtsilä; Siem Offshore selects Wärtsilä’s design and integrated solution

Wärtsilä has been awarded the contract to supply the design and an integrated solution for a new large platform supply vessel (PSV). The ship will operate primarily on liquefied natural gas (LNG) and is owned by Siem Offshore, the Norway-based provider of marine services to the oil and gas industry. It will be operated under charter by A/S Norske Shell. The PSV is being built at the Remontowa Shipbuilding’s yard in Poland.

This order follows a similar one placed in November 2012 with the same scope of supply for another Siem Offshore owned PSV. Almost half of the vessels in Siem Offshore’s fleet already feature Wärtsilä ship designs and Wärtsilä equipment.

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 fulfill the highest possible Environmental Regularity Number (ERN) of, which represents the vessel’s capability for maintaining its position and normal operations under certain weather conditions.

The 89.2-meter (293 ft) 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 latest order emphasizes Wärtsilä’s front runner status in the LNG PSV design market. During the past year, three major oil companies have chosen Wärtsilä’s LNG PSV design and integrated solution for their North Sea tenders. This line of success dates back ten years, when the first two LNG PSVs designed by Wärtsilä for operations in the North Sea were chartered by Norwegian oil company Statoil.
