Offshore & subsea - 14 September 2021

The Helix Q5000 well intervention vessel and 15K Intervention Riser System have been charted by a major operator in the US Gulf of Mexico.

The engineering design work will include flow assurance definition and design of the subsea system connecting the wellhead platform to the FPSO including the flexible flowlines, dynamic risers and a mid-water arch structure.

McDermott will provide engineering, procurement, construction, installation and commissioning (EPCIC) for 30 miles (50 km) of pipeline and approximately 9 miles (15 km) of umbilical to connect five drill centres to a new offshore platform.

The survey is designed to illuminate the regional plays in the ultra-deep and deepwater areas with a new azimuth and to provide prospectivity insights of an oil-prone area in relation to recent key wells and the shallow water geology.
