BW Energy has revised its Gabon drilling schedule and suspended its 2026 capital expenditure forecast after the Prospector 5 drilling rig sank, disrupting the MaBoMo Phase 2 project offshore Gabon. The company had originally expected additional oil production from the phase to come online in the first quarter of 2027; that timeline is now under review.
The loss of the Prospector 5 is a significant operational setback for BW Energy's Gabon programme. MaBoMo Phase 2 represented a defined next step in the company's production growth offshore Gabon, and the rig loss removes a critical piece of infrastructure from the schedule. With the 2026 capex forecast suspended, investors and contractors alike face a period of uncertainty around the pace and funding of the revised drilling campaign.
Replacement rig sourcing will now become the central near-term question for BW Energy's operations team. Securing an alternative unit in a market where jackup and platform rig availability can be constrained will determine how much of the original 2027 production timeline can be recovered. The scope of any delay will depend on both rig availability and the company's revised financing decisions once a new capex framework is established.
For the broader Gabon offshore supply chain, the incident underscores the operational and insurance exposure that comes with aging rig assets working in the region. Prospector 5 was a relatively compact unit suited to the water depths and well types associated with BW Energy's Gabon acreage. Finding a comparable replacement — one that fits the specific requirements of the MaBoMo Phase 2 well programme — will require careful technical matching, not simply a like-for-like swap from the available rig list.
BW Energy has built a focused upstream position in Gabon, and MaBoMo Phase 2 was a key pillar of its near-term production growth story. The suspension of the 2026 capex forecast signals that the company is taking time to reassess the full financial and logistical picture before committing to a revised execution plan. Partners and service companies engaged with BW Energy's Gabon activities should expect an updated schedule to emerge once rig replacement options are evaluated and a new capex framework is confirmed.
