Senegal’s PETROSEN Builds Maritime Capacity Through Teranga Naval Services
)
Senegal is building domestic maritime capacity alongside the development of its offshore oil and gas industry, with PETROSEN Holding now holding 100% of Teranga Naval Services (TNS). The move gives the national oil company a wholly owned platform for securing offshore petroleum installations while expanding into maritime logistics, transport, supply and catering services.
TNS has an exclusive economic authorization under Senegal’s Decree No. 2023-1241 of June 2023 to provide patrol-vessel services for the security of oil and gas installations. Its mandate covers the security of offshore fields, installations and adjacent sites, as well as maritime transport and logistics between the coast and offshore platforms.
The company is now being operationalized as PETROSEN consolidates its ownership. The project documentation states that PETROSEN acquired the remaining interests previously held by TNS SAU and KAIROS ENERGY, bringing its ownership to 100%, with the company’s commercial and corporate formalities being completed.
A key commercial opportunity is emerging through negotiations with Woodside Energy for a multi-year contract. A first offer has already been submitted, with a revised offer expected following ongoing discussions. The proposed operating framework would include a tripartite steering committee comprising Woodside, TNS and PETROSEN, while performance would be monitored through quarterly indicators covering vessel availability, HSE incidents, ROV reporting and CO₂ emissions.
TNS has identified a 70-meter DP2 multipurpose vessel with 85 tons of bollard pull for its initial fleet. The vessel is intended to support patrol operations, transportation and personnel transfer, with acquisition and mobilization still to be finalized. The project also requires the establishment of the necessary financial guarantees and insurance arrangements, including a 5% performance bond through Banque Nationale pour le Développement Économique, hull and machinery insurance and P&I coverage.
The broader strategy extends beyond offshore security. PETROSEN’s project plan calls for diversification into offshore supply, logistics, transport, catering and related services, with the stated objective of turning TNS into a profit center while strengthening Senegalese participation in the maritime oil and gas sector. The company also aims to reduce the overall cost of securing offshore assets by replacing multiple specialized charter arrangements with an integrated solution.
The development comes as Senegal’s offshore industry moves into a more established production phase, with Sangomar already producing and GTA LNG operational, while projects including Yakaar-Teranga continue to advance. MSGBC Oil, Gas & Power 2026, taking place December 1–3 at CICAD in Dakar, will bring governments, national oil companies, operators, investors and service providers together around the infrastructure, supply chains and local businesses needed to support this next phase of regional development.
TNS represents more than an offshore security operation: it is an example of Senegal seeking to build national capability around its emerging petroleum industry. As MSGBC Oil, Gas & Power 2026 showcases the basin’s expanding project pipeline, the development highlights opportunities for local and international companies across maritime services, logistics, vessel operations, offshore supply and associated infrastructure.
