SLB, through its OneSubsea joint venture, has been awarded a major engineering, procurement and construction (EPC) contract by Italian energy company Eni for the third phase of the Baleine offshore development in Côte d’Ivoire.
The contract covers the supply of integrated subsea production systems for 13 new wells, marking another significant step in the expansion of the Baleine field, one of the country’s largest offshore hydrocarbon discoveries. The latest award reinforces OneSubsea’s role in delivering advanced subsea technologies for large-scale deepwater developments in West Africa.
As part of the project, OneSubsea will design, manufacture and deliver a complete subsea production package, including subsea trees, manifolds, umbilicals, multiphase flowmeters and control systems. The scope also includes installation, commissioning and long-term operational support throughout the life of the field.

EPC approach
The company said its integrated EPC approach is intended to simplify project execution, improve operational efficiency and help Eni maintain the accelerated development timeline for the third phase of the Baleine project. Execution of the contract will be supported by OneSubsea’s existing operations and workforce in Côte d’Ivoire, allowing the project to benefit from local expertise while contributing to the continued growth of the country’s offshore oil and gas industry.
“Baleine Phase 3 brings together scale and execution certainty,” said Mads Hjelmeland, Chief Executive Officer of SLB OneSubsea. “Through our subsea production system technology and by leveraging our established local presence, we are supporting Eni’s efforts to advance a complex, deepwater project efficiently while contributing to the long-term development of offshore resources in Côte d’Ivoire.”
The Baleine development has become a key project in Côte d’Ivoire’s efforts to expand domestic oil and gas production, with successive phases aimed at increasing output while strengthening the country’s position as an emerging offshore energy producer. The latest contract also reflects the growing demand for integrated subsea production solutions that can reduce project complexity and support faster delivery of deepwater developments across Africa, where operators continue to invest in unlocking offshore resources through advanced engineering and digital technologies.
