Borr Drilling said its Prospector 5 drilling rig was involved in an incident at about 20:37 local time on 24 October while conducting jacking operations offshore Gabon for a planned drilling campaign. [E1]
Preliminary information from Borr Drilling says a punch-through event during preload caused a loss of stability and the rig subsequently sank. [E2]
Of 115 people aboard, 110 had been safely accounted for and five remained unaccounted for, Borr Drilling said, with extensive search-and-rescue operations under way. [E3]
BW Energy confirmed that the incident involved the Borr-owned and operated rig on Gabon’s Dussafu Marine licence. [E4]
BW Energy said production at the MaBoMo facility was shut under standard procedure during drilling preparations; it reported no damage to the facility or related equipment, and no accidental discharge of harmful substances to sea from the facility. [E5]
