The advanced vessel will be built by Korea-based company Hyundai Heavy Industries (HHI) and is expected to be delivered in 2015.
Along with accommodation capacity of 110 people, the vessel will include 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 company said.
The vessel will also be equipped with six main engines in three separate engine rooms designed to maximise performance in Dynamic Positioning (DP) Class III.
Subsea 7 Commercial executive vice president Steve Wisely said the company is happy 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," he added.
The company, recently, has acquired two vessels, including Seven Atlantic in 2010 and Seven Havila in 2011, and the new-build DSV will be the third to join in the Subsea 7 fleet.
