Petrofac Chooses Ulstein Pipelay Design

Sharjah based Petrofac is to build the Petrofac JSD 6000 deepwater derrick lay vessel, a customized Ulstein SOC 5000 developed by Dutch design company Ulstein Sea of Solutions. The vessel will be constructed at the ZPMC yard in China and be available for construction and installation activities in early 2017. 

The dynamically-positioned Petrofac JSD 6000 is a unique, innovative design featuring J-Lay, S-Lay and heavy lift capabilities, allowing it to serve deepwater and SURF markets as well as shallow water EPCI projects.

The design features an NOV revolving main crane with 5,000mt lifting capacity. But what makes this vessel truly unique is the combination of a 600mt Remacut S-lay system via a center firing line below main deck and a 2,000mt IHC EB J-lay system via a moon pool. This double deck configuration, a distinctive feature in Ulstein Sea of Solutions designs, allows for a large, unobstructed deck area and below deck pipe fabrication.

 ’We are very pleased that Petrofac selected us for designing their first offshore construction vessel,’ says Edwin van Leeuwen, managing director at Ulstein Sea of Solutions. ‘We feel it is a recognition of our design capabilities for this high end market. It is the third customised version of our successful Ulstein SOC 5000 design after the ‘Seven Borealis’ and ‘Aegir’, which are both already in operation. The success of the project comes for account of the close cooperation between Petrofac’s team and our project team, managed by Sjaak Jan Jiskoot.’

Ulstein Sea of Solutions specializes in the design and development of ships for the offshore drilling, construction and renewable market, fully customizing them to meet client specific operational requirements.
