Politics: Gabon
A Gabonese party says most of the officials and both oil companies it wrote to have not answered its questions about a drilling rig that sank off the south coast. It also wants house demolitions in the capital, Libreville, paused until families have guarantees.
The Democratic and Socialist Front (FDS), a Gabonese political party, demanded answers on Friday 13 November 2026 about the sinking of an offshore drilling rig off Mayumba, a coastal town in southern Gabon. Its president, Anges Kévin Nzigou, told a press conference in Libreville that only one of the officials and companies he wrote to had replied.
The Prospector 5, owned by Borr Drilling, an offshore drilling contractor, is a jack-up rig, a drilling platform that stands on long legs on the seabed. For US readers the story shows how one accident can delay offshore oil output and prompt calls for answers on safety.
Key Facts
- Who. Anges Kévin Nzigou, president of the Democratic and Socialist Front (FDS), a Gabonese party.
- What. The FDS wants an open investigation of the Prospector 5 rig sinking and a pause in Libreville evictions.
- Where. Press conference in Libreville; the rig sank off Mayumba, southern Gabon.
- When. Friday 13 November 2026; the rig sank on Saturday 24 October 2026.
- Toll. Borr Drilling confirmed four deaths and one person unaccounted for on 2 November 2026.
What the FDS Is Asking About the Rig
Nzigou said the FDS wants an independent, rigorous and transparent investigation into the circumstances of the sinking, who is responsible and how to prevent a repeat. He said he wrote to the vice-president of the government, the ministers of Transport, Petroleum and the Environment, and the companies Borr Drilling and BW Energy, the oil company that had hired the rig.
According to the FDS, only the Environment minister replied, and Nzigou praised the speed of that answer. “Silence does not solve problems; it makes them worse,” he said (“Le silence ne règle pas les problèmes.
Il les aggrave”). He added that oil extraction must not come at the expense of workers’ safety and dignity.
The party says it will keep pressing the authorities on the rig and on the evictions.
What Is Known About the Sinking
Borr Drilling said 115 people were aboard when the Prospector 5 sank on Saturday 24 October 2026 at about 20:37 local time. It said 110 of them returned ashore, as set out in our first report on the sinking.
Gabonese authorities said that three bodies were located inside the submerged wreck on Wednesday 28 October, found with underwater robots. On 2 November Borr confirmed a fourth death, with one person still unaccounted for and the search continuing.
Borr’s preliminary information points to a “punch through”. That is when the seabed gives way under a leg of the rig during the preload test, which checks that the ground can carry its weight.
Borr has engaged a classification society, an independent rig inspector, to investigate. The prosecutor’s office in Tchibanga, a court office in southern Gabon, opened a judicial investigation on 25 October.
BW Energy, the oil company that had hired the rig, said on 29 October that the incident affects the timing of production from Phase 2 of MaBoMo, its offshore oil project, as covered in our report on the delay at BW Energy. Production at MaBoMo has resumed, and BW Energy has identified no damage to its facilities.
In Plain English
- FDS. The Democratic and Socialist Front, a Gabonese political party led by Nzigou.
- Preload. A test in which crews add weight so the rig legs show the seabed can carry it.
- Classification society. An independent body that inspects ships and rigs and checks safety standards.
- Évictions. Gabon’s “déguerpissements”: the clearing of homes built on land the state wants for roads.
The Evictions Question in Libreville
The FDS also asked the Housing minister to explain the legal basis, the compensation and the support for residents hit by demolitions in Okala, Diba-Diba and Lac Bleu, districts of Greater Libreville. It called for the evictions to be suspended until families receive guarantees, and said it is not against urban development.
Demolitions began on Wednesday 4 November 2026 to make room for new roads, the government has said. On Monday 9 November President Brice Clotaire Oligui Nguema of Gabon announced 4 billion CFA francs, the Central African currency (about US$6.7 million, at about 595 CFA francs per US$ via the euro peg) more for compensation, as set out in our report on the compensation.
Nzigou welcomed what the FDS describes as the president’s call for an urgent meeting on the issue. “Behind every demolished wall, there is a family,” he said, and he asked for clear rules, appeal rights and rehousing for those affected.
A Party Summit in Addis Ababa
The FDS took part in the second African Political Parties Summit, a gathering of party delegations in Addis Ababa, the capital of Ethiopia, held from 5 to 7 November 2026. The summit adopted the Addis Ababa Declaration, which the FDS welcomed.
The FDS says the declaration commits parties to constitutional principles, democratic accountability and rejecting unconstitutional changes of government. It calls these principles essential to stability in Africa.
What It Means for Readers Abroad
The rig was to drill wells for MaBoMo Phase 2, and BW Energy said on 29 October that its loss affects the timing of that production. For the 110 people who returned ashore and the families of the dead, the open question is who is responsible, which is what the FDS is pressing.
The evictions matter to the families living on the planned road routes in Libreville, who face the loss of their homes. For wider background, see who runs Gabon’s economy and our Gabon page.
What Is Not Known
We have seen no public reply from the other ministers or from Borr Drilling and BW Energy to the FDS letters. We found no published date for the findings of the judicial investigation or the independent review.
The latest update we found, Borr’s of 2 November, leaves one person unaccounted for. We could not confirm the full text of the Addis Ababa Declaration, so the FDS’s description of it stands as the party’s account.
