Ship history

In January 2014, Sharjah based Petrofac ordered the Petrofac JSD 6000 deepwater derrick lay vessel, a customised ULSTEIN SOC 5000 design developed by Ulstein Design & Solutions B.V. The ship was contracted to ZPMC shipyard in China. Petrofac terminated the construction contract with the yard in October 2015.”

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

The JSD 6000 vessel is the third customised version of the ULSTEIN SOC 5000 design after the ‘Seven Borealis’ and ‘Aegir’, which are both in operation.

24 April 2018: Petrofac signed an agreement to sell the JSD 6000 deepwater derrick lay vessel project to Shanghai Zhenhua Heavy Industries (ZPMC). Petrofac will provide technical support for the construction of the vessel, which is expected to complete in 2022.
