MILAN, Italy – The Saipem jackup drilling rig Perro Negro 6 has sunk offshore West Africa in 40 m (131 ft) of water.
Saipem says the seabed under one of the three legs collapsed, causing the rig to tilt and suffer hull damage which caused water intake. The event came during rig positioning on July 1, prior to start of drilling.
As of last report, Saipem had evacuated all personnel. One person is missing and six had minor injuries. No environmental damage is reported.
The rig was near themouth of the Congo River between Angola and the Democratic Republic of Congo.
