Borr Drilling’s Prospector 5 jack‑up rig sinks off Gabon, crew missing

On 24 October 2026 at about 20:37 local time, Borr Drilling’s Prospector 5 jack‑up rig sank during preload and jacking operations offshore Gabon. The rig, contracted to BW Energy, had 115 personnel on board; 110 were rescued and five remained unaccounted for, with later reports indicating one fatality and four still missing. Borr Drilling’s CEO Bruno Morand said the company’s priority is the ongoing search and rescue effort.

The incident triggered an immediate drop in Borr Drilling’s share price, falling about 9 % in pre‑market trading. The loss of the rig may also delay BW Energy’s development schedule and affect future revenue, as the rig was booked through mid‑2027.
