The Sevan Driller is currently off-hire due to problems with the blow-out preventer (‘BOP’) which started on November 2.
During routine testing of the BOP, the locking system of one of the rams jammed in locked position. Sevan Marine is working together with Petrobras and the supplier, Cameron, to find a solution to the problem. If a solution is not found, the BOP must be pulled to the surface and repaired.
