Subsea7 has been awarded a substantial contract by Chevron’s subsidiary Noble Energy EG Ltd for subsea installation on the Aseng Gas Monetisation Project offshore Equatorial Guinea. The scope includes flowline and umbilical installation for a single-well tieback in 800-metre water depths.
Subsea7 has announced a substantial contract award from Noble Energy EG Ltd, a Chevron company, for the subsea installation scope on the Aseng Gas Monetisation Project offshore Equatorial Guinea, according to company disclosures. The project entails a single-well tieback connecting the Aseng field to the existing Alen platform.
The scope of work includes transport and installation of approximately 19 kilometres of rigid production flowline and 20 kilometres of umbilicals, along with associated subsea structures and tie-ins at water depths of 800 metres.
Project management and engineering will begin immediately from Subsea7’s Paris office, with additional support from teams in Lisbon and Equatorial Guinea. Offshore activities are scheduled to commence in 2026.
The contract reflects ongoing investment in gas monetisation across West Africa’s deepwater basins, where operators are leveraging existing infrastructure to tie back satellite fields.
For Chevron, the Aseng project optimises capacity at the Alen platform, reducing unit development costs compared to greenfield installations. Subsea7’s execution model—centralised engineering in Paris with local support—demonstrates a hybrid approach to managing technical complexity while maintaining regional presence.
Subsea installation contractors benefit from continued deepwater tieback activity as majors prioritise near-field exploration and infrastructure-led exploration. The 800-metre water depth falls within the operational sweet spot for rigid flowline and umbilical installation, where specialised vessels and trenching equipment are required. Suppliers of subsea hardware, including connectors and manifolds, may see follow-on opportunities as the project progresses toward offshore execution in 2026. Regional stakeholders in Equatorial Guinea, including local content service providers, could gain from support contracts during offshore activities.
Subsea7 is a subsea engineering, construction, and services contractor operating in offshore energy markets.
Noble Energy EG Ltd is a subsidiary of Chevron Corporation, active in Equatorial Guinea’s oil and gas sector.
