Borr drilling rig sinks off Gabon coast during operations
A Borr Drilling offshore rig sank near Mayumba in Gabon, leaving one person dead and four individuals unaccounted for.
Key points
- The Prospector 5 rig experienced a stability failure during jacking operations off Gabon.
- Search and rescue operations involve local authorities, BW Energy, and the rig operator.
- Production in the affected area has been suspended as a precaution.
What happened
An offshore drilling unit operated by Borr Drilling went down off the coast of Mayumba in Gabon on the evening of 24 October. Offshore Technology reported that the Prospector 5 rig suffered a punch-through incident during jacking activities. The structure was preparing for a drilling campaign at the Dussafu Marin permit when it lost stability.
Reuters noted that 115 personnel were aboard the installation when the accident occurred. While the company initially stated that five workers were missing, subsequent updates accounted for one fatality, leaving four individuals still unaccounted for. Among those missing are reportedly three Gabonese citizens and an expatriate, while an Indian national was found dead.
Response and precautions
Borr Drilling Chief Executive Officer Bruno Morand stated that the company is prioritising support for rescue operations and personnel welfare. An onshore emergency response team has been activated, collaborating with local authorities and the asset customer, BW Energy. BW Energy holds a majority working interest in the Dussafu license, alongside partner Panoro Energy.
Gabon's Ministry of Petroleum and Gas established a crisis committee comprising ministry officials, naval forces, Gabon Oil, BW Energy, and the drilling contractor. Minister Clotaire Kondja ordered a technical inquiry into the sinking and instructed the navy to intensify search efforts at sea. Environmental protection measures were also initiated to safeguard the coastline and nearby Mayumba National Park, with Panoro Energy confirming that local production has been halted.
Why it matters
This incident highlights the operational risks inherent in offshore oil and gas exploration, particularly during pre-drilling jacking procedures. For energy investors and operators across the African continent, safety management and rapid emergency response protocols remain critical operational pillars. Fuel exports account for 54% of merchandise exports in Gabon according to 2023 World Bank figures, underscoring the economic significance of the hydrocarbon sector to the nation. While no environmental discharges have been reported following the deployment of pollution-response resources, disruptions to regional output can introduce volatility into project timelines and asset valuations.
