Ulstein design for PetrofacVessel & ROV News // January 20, 2014
Petrofac JSD 6000 is based on the Ulstein SOC 5000 design concept.
Sharjah-based Petrofac has selected Ulstein Sea of Solutions in The Netherlands to design Petrofac JSD 6000, the deepwater derrick lay vessel it plans to build.
The vessel will be a 'customised' version of the ULSTEIN SOC 5000 and will be built at the ZPMC yard in China and become available for construction and installation activity in early 2017.
The dynamically-positioned unit is an innovative design with J-Lay, S-Lay and heavy lift capabilities, allowing it to serve the deepwater and SURF markets as well as shallow water EPCI projects.
The design features a National Oilwell Varco (NOV) revolving main crane with 5,000 tonnes lifting capacity, but what makes the vessel unique is the combination of a 600 tonne Remacut S-lay system via a centre firing line below main deck, and a 2,000 tonne IHC EB J-lay system via a moonpool. A 'double deck' configuration, a distinctive feature in Ulstein Sea of Solutions designs, allows for a large, unobstructed deck area and below deck pipe fabrication.
The vessel will be 215.9m overall with a length between perpendiculars of 197.6m, beam (moulded) of 49.0m, depth (main deck) of 22.4m, operating draught of 10.9m, service speed of 12 knots and installed power 6 x 8,500kW. The DP3 unit will also have an eight-point mooring system. it will be classed by Lloyd’s Register and have ice class to Finnish Swedish 1C standard. The deck strength will be 15tonnes/m2 and the vessel will have accommodation for 399.
