Siem Offshore has awarded a contract to Norway’s Hellesoy yard to build a dual-fuel platform supply vessel (PSV), with an option for one additional vessel.
The vessel will be built to VS 4411 DF design, with a length of 89m, beam of 19m, a deck of 970m² and maximum of 5,500dwt.
Designed in collaboration with Wärtsilä Ship Design, the vessel will have a dual-fuel system for the use of either LNG or marine diesel oil.
Modern fire-fighting and emergency preparedness systems will be equipped in the new vessel, in addition to the under-deck capacities suited for its intended operations.
The vessel will be charted to Total E&P Norge under a four-year contract, with four one-year options.
The new PSV will be used to serve the Martin Linge field in the North Sea North-West of Stavanger from the third quarter of 2014.
Earlier in October 2012, Siem Offshore exercised an option with Singapore’s STX OSV Holdings (STX OSV) to design and build two additional offshore subsea construction vessels (OSCV), and awarded a $55m contract to Fjellstrand to build one in-field support vessel.
The vessels ordered with STX OSV will be based on the OSCV 11 design and will have a length of 121m and a beam of 22m.
STX OSV Tulcea in Romania will deliver the hulls of the vessels, while the complete vessels are scheduled to be delivered by STX OSV Brattvaag in Norway in the second quarter of 2014.
