MILAN -- Italy's Saipem said Tuesday that the drilling rig Perro Negro 6 offshore Angola, sank after an accident last night and one crew member is missing.
Saipem said that the jackup drilling rig tilted due to the collapsing of the seabed under one of the three legs, causing water intake.
There has been no damage to the local environment so far, the company added.
The sinking happened at night between the coast of Angola and Congo, near the mouth of the Congo river.
Saipem said that it is covered by insurance for the loss of equipment, wreckage removal, as well as for any possible environmental damages.
