Rescue efforts to find a missing Bulgarian man after the sinking of an oil rig off the African coast are still continuing, Saipen said today.
The Perro Negro 6 jackup rig capsized and sank on Monday night while operating between the coasts of Angola and the Democratic Republic of Congo.
One member of the 103 crewmembers was reported missing after the accident, with six more suffering minor injuries.
Last night the Italian owners of the rig said search efforts to find the missing man were still ongoing by emergency authorities.
The rig, which was being operated by Chevron, tilted and took on water after the seabed collapsed under one of the three legs.
The company confirmed that after monitoring the wreck, there was no evidence of any kind of spillage from it after its collapse.
Saipem were awarded a three-year contract for offshore drilling off Angola by Chevron, starting in the second quarter of 2012, using the Perro Negro 6 rig.
