McDermott International will construct and install subsea risers and flowlines on Petrobras’ Sepia field off Brazil.
McDermott’s Rio de Janeiro office will perform the work with support from its Houston office.
It will use five vessels for the installation work at ultra-deepwater depths up to 7,021 feet.
The engineering work is expected to begin immediately.
The exact contract value was not disclosed, but is worth between £190 million and £385m.
The project scope includes detailed engineering, surveys, supply, installation and pre-commissioning of rigid pipelines, jumpers, buoyance modules, strakes and riser monitoring systems for seven-riser wells, connected to the Carioca floating production, storage and offloading vessel.
Mark Coscio, McDermott’s senior vice president for North, Central and South America, said: “McDermott has had a strong presence in Brazil going back more than four decades, and we see tremendous opportunity for growth in the region.
“We will use our first-class assets and proven track record to deliver the highest levels of safety, quality and cost-efficiency during the first phase of this important greenfield development.”
