A semisubmersible drilling rig under construction at a yard in Korea is resting on the seabed after water entered the pontoon hull and the unit sank.
The rig, Deepsea Aberdeen, is being built for Odfjell Drilling at the Daewoo Shipbuilding and Marine Engineering (DSME) yard in Korea.
The unit was evacuated after the water ingress and the rig stabilized on the sea bed, with draft at around 21m, said Odfjell.
Odfjell said it is awaiting further information from DSME.
Deepsea Aberdeen is an enhanced GVA7500 sixth generation harsh environment design. It was due for delivery in May 2014, and would be a sister rig to the Deepsea Atlantic and Deepsea Stavanger (pictured), already delivered by DSME.
On delivery, Deepsea Aberdeen, was due to start drilling operations under a seven-year contract with BP in UK waters west of Shetland.
This would involve drilling and completing more than 25 wells in the Schiehallion and Loyal fields, between 2014 and 2022, as part of the Quad 204 development.
