Vantage Drilling is to provide design, construction and commissioning services to Aker Drilling for two ultra deepwater drillships.

The vessels are being built by Aker at the Daewoo Shipbuilding & Marine Engineering (DSME) shipyard in Okpo, Korea.

The high-specification drillships will be capable of dual-activity operations in water depths of 12,000ft and drilling depths of 40,000ft.

Aker Drilling may expand the supervision agreements with Vantage if it exercises its option of building two more drillships at DSME.
