The Subsea Integration Alliance is made up of Subsea 7 and SLB’s OneSubsea.
Although Subsea7 did not disclose the exact value of the contract, the company indicated that it was in the range of $150m–300m.
The project management and engineering responsibilities will be distributed across Subsea 7’s offices in Paris, France; Luanda, Angola; Lisbon, Portugal; and Sutton, UK.
In May 2024, ExxonMobil, together with Azule Energy, Equinor and Sonangol, discovered oil at the Likembe-01 exploration well. The offshore find, reported by Angola’s National Oil, Gas and Biofuels Agency, is situated within the Kizomba B development zone.
Drilling operations were carried out between February and April 2024 at a water depth of 1,200m. The well successfully identified Miocene-age reservoirs and was drilled to a total depth of 3,013m.
Subsea7 global projects centre east senior vice-president David Bertin said: “This project builds on our track record in West Africa, Australia and the US.
“Together with ExxonMobil, we are committed to delivering the project safely, efficiently and to the highest standards, while continuing to support the development of local capabilities in Angola.”
Within the integrated delivery model of the SIA, SLB’s OneSubsea will manage the umbilical components from its Centre of Excellence in Moss, Norway. This will be complemented by additional project management and engineering support in Houston, US.
SIA CEO Olivier Blaringhem said: “This award further strengthens our relationship with ExxonMobil.
“It demonstrates how early collaboration through Subsea Integration Alliance enables an optimised development solution and underpins our integrated commercial model.”
Last month, Subsea7 obtained a ‘substantial’ contract from Noble Energy EG, a Chevron subsidiary, for subsea installation work at the Aseng gas monetisation project off the coast of Equatorial Guinea.
This development comes after Chevron’s final investment decision on the project.
The initiative involves connecting the Aseng field to the existing Alen platform via a single-well tie-back.
