The news has also been confirmed by the rig’s owner, Saipem, which said that the Perro Negro 6 was the rig involved in the incident.
The Italian oilfield services provider said that one of the jack-up rig’s three legs collapsed, causing the rig to suddenly tilt and start taking water. The incident, according to Saipem, occurred during the rig positioning on location between the coasts of Angola and the Democratic Republic of Congo, in approximately 40 meters of water. 6 crew members have sustained minor injuries. At approximately 10:30 am CET, the rig, with no personnel on board, capsized and sank.
