WÃ¤rtsilÃ¤ announced today they have been contracted to supply an integrated engineering solution to an LNG-powered Platform Supply Vessel (PSV) newbuild project in conjunction with Norwegian yard HellesÃ¸y Verft and shipowner, Siem Offshore. WÃ¤rtsilÃ¤ will provide ship design services and the vessel’s power and propulsion system.
This will be the eighth vessel built at HellesÃ¸y to be based on the WÃ¤rtsilÃ¤ Ship Design VS 485 series and will be Siem Offshore’s first LNG-powered PSV. Upon commissioning i 2014, the vessel with be on charter contract with TOTAL for work on the Martin Linge oilfield, North-West of Stavanger, Norway.
The vessel is of WÃ¤rtsilÃ¤ VS4411 LNG PSV design and features WÃ¤rtsilÃ¤ power and propulsion, electrical and automation systems, including a complete four-split WÃ¤rtsilÃ¤ 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 WÃ¤rtsilÃ¤ LNGPac LNG storage and handling system.
Close to half of Siem’s fleet consists of vessels with WÃ¤rtsilÃ¤ ship design and equipment. Ten of the company’s anchor handling tug supply (AHTS) vessels have been designed by WÃ¤rtsilÃ¤ and are equipped with complete hybrid diesel electric propulsion systems from WÃ¤rtsilÃ¤.
WÃ¤rtsilÃ¤’s acquisition of Hamworthy and the subsequent integration of Hamworthy’s portfolio has expanded WÃ¤rtsilÃ¤’s offering with enhanced gas bunkering, storage and feedsystem, thereby strengthening its technology position in LNG powered vessels.
With this new order, the number of LNG powered PSVs reaches 17. Of those, WÃ¤rtsilÃ¤ has designed eight and has supplied dual-fuel machinery to 15 of these 17 vessels. Last year, WÃ¤rtsilÃ¤ expanded its offering to include LNG storage and gas handling systems. This vessel marks the fifth LNG powered PSV vessel to use WÃ¤rtsilÃ¤’s gas handling system.
