SEPTEMBER 2, 2013 — Wärtsilä is to supply the design and an integrated solution for a new large platform supply vessel (PSV) that will be operated by Siem Offshore under charter to A/S Norske Shell.

The PSV will operate primarily on liquefied natural gas (LNG) and is being built by Polish shipbuilder Remontowa.

Wärtsilä'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 m 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 (see earlier story). Almost half of the vessels in Siem Offshore's fleet already feature Wärtsilä ship designs and Wärtsilä equipment.

"Wärtsilä is the marine sector's leading total solutions provider and this capability has enabled us to develop comprehensive integrated solutions that enhance efficiency, reduce operating costs, and promote environmentally sustainable shipping. Furthermore, by facilitating the use of LNG as a clean and economically competitive marine fuel, we have created a paradigm shift that benefits our customers and the industry as a whole. Our success in supplying major oil companies with LNG fueled PSVs is testament to this," says Magnus Miemois, Vice President, Wärtsilä Solutions.
