Borr Drilling Rig Sinks Offshore Gabon, Five Workers Missing

By Charles Kennedy - Oct 25, 2026

Borr Drilling has confirmed that its Prospector 5 offshore drilling rig sank off the coast of Gabon on Saturday, October 24, following an apparent seabed failure during preparations for a drilling campaign operated by BW Energy.

The incident occurred at approximately 8:37 p.m. local time while the jack-up rig was conducting preloading and jacking operations at the Dussafu Marin oil licence.

Of the 115 personnel aboard the rig, 110 were safely accounted for, while five remained missing when Borr Drilling issued its initial statement on Sunday.

Reuters subsequently reported, citing three sources familiar with the incident, that one of the missing workers had been found dead, leaving four unaccounted for. However, Gabonese authorities had not officially confirmed the fatality and continued to report five missing personnel.

Preliminary findings suggest the rig suffered a punch-through event, in which one or more supporting legs suddenly penetrate weaker seabed sediments, potentially causing a rapid loss of stability. The Prospector 5 subsequently sank.

Borr Drilling activated its emergency response team and is coordinating rescue efforts with BW Energy and Gabonese authorities.

Gabon has also mobilized its navy and launched an investigation into the accident.
