McDermott Delivers First Subsea Project for TotalEnergies in Angola

Amazon Vessel Brings Strategic Value to Successful Completion

HOUSTON, Oct. 16, 2025 /PRNewswire/ -- McDermott announces the safe and successful completion of engineering, procurement, construction, installation, pre-commissioning and commissioning activities for TotalEnergies' Begonia field development. Located in Block 17/06, approximately 150 kilometers off the coast of Angola, Begonia marks McDermott's first subsea project in the country.

Awarded in 2022, the project followed the company's integrated execution model, drawing on its global engineering and procurement expertise, growing onshore fabrication capabilities in Luanda and offshore installation supported by its versatile marine fleet. McDermott's Amazon vessel alone installed more than 40 kilometers of rigid pipelines, while its North Ocean 102 vessel completed the project's subsea umbilical scope.

"This milestone reflects the strength of our integrated subsea capabilities, executed seamlessly from engineering through offshore installation," said Mahesh Swaminathan, McDermott's Senior Vice President, Subsea and Floating Facilities. "It reinforces the strategic value the Amazon brings to our operations, especially in markets where deepwater infrastructure plays a vital role in advancing energy security. This outcome also speaks to the strength of our partnership with TotalEnergies, the commitment of our local teams and partners in Angola, as well as the strategic importance of West Africa in our portfolio."

The Begonia development consists of five subsea wells tied back to the existing Pazflor floating production, storage and offloading (FPSO) vessel in Block 17. First oil was achieved in July of this year, with the new infrastructure expected to add approximately 30,000 barrels of oil per day to Pazflor's existing production capacity.
