Subsea7 announced the award of a substantial1 contract by Noble Energy EG Ltd (a Chevron Company) for the subsea installation scope on the Aseng Gas Monetisation Project, offshore Equatorial Guinea. The project involves a single-well tieback connecting Aseng field to the existing Alen platform.

The scope of work covers the transport and installation of approximately 19 kilometres of rigid production flowline and 20 kilometres of umbilicals, along with associated subsea structures and tie-ins in water depths of 800 metres.

Project management and engineering will commence immediately and will be managed from Subsea7’s Paris office, with additional support from teams in Lisbon and Equatorial Guinea. Offshore activities are expected to begin in 2026.

David Bertin, Senior Vice President for Subsea7’s Global Projects Centre East, said: “This award represents an important milestone in our ongoing global relationship with Chevron. Subsea7 has operated in Equatorial Guinea for nearly two decades, supporting offshore construction and inspection, maintenance and repair activities. We look forward to continuing our collaboration with Chevron on the Aseng Gas Monetisation Project, continuing to deliver safe, high-quality offshore installation services in West Africa.”
