New Build Diving Vessel to Join Subsea 7 Fleet

22 November 2012

Subsea 7 has signed a contract to build a new Dive Support Vessel (DSV). The new vessel will be delivered in 2015.

This state-of-the-art vessel will be built by Korean company Hyundai Heavy Industries (HHI), one of the world’s largest ship building companies.

With accommodation for 110 people, the DSV will incorporate an 18 man saturation system supplied by Drass and rated for 300m with two moon-pool deployed three man diving bells and two 18-man hyperbaric life-boats.

The vessel will be equipped with six main engines in three separate engine rooms designed to maximise performance in Dynamic Positioning (DP) Class III.

Subsea 7 Executive Vice President Commercial Steve Wisely said: "To build and equip this vessel we are delighted to work with industry leaders HHI, Drass and Wartsila Ship Design. The vessel will reinforce our leading diving capabilities with one of the world’s largest DSV fleets, and enable us to continue to serve our clients in an efficient, cost-effective and safe manner on many future projects.”

This will be the third new-build DSV to join the Subsea 7 fleet in recent years, having taken delivery of the Seven Atlantic in 2010 and Seven Havila in 2011.
