ABERDEENSHIRE, UK – Subsea 7 has awarded ACE Winches two contracts for deepwater projects in the Gulf of Mexico.
For the Shell-operated Vito project, the contract covers the engineering, project management, manufacture, operational personnel, installation, and pull-in of one 14-in. export steel catenary riser (SCR) pipeline, one 10.75-in. export pipeline, two 10.75-in. SCR production flowlines, one 10.75-in. SCR gas lift flowline, and the umbilical system in a water depth of 1,260 m (4,130 ft).
Located over four blocks in the Mississippi Canyon area, the Vito development will consist of a semisubmersible host facility and eight subsea wells with deep in-well gas lift. First oil is scheduled for 2021. Vito is about 241 km (150 mi) south of New Orleans.
For BP’s Mad Dog Phase 2 project, the contract scope includes engineering, project management, manufacture, operational personnel, installation, and pull-in of six catenary and three flexible risers ranging from 8-in. to 16-in. and four umbilical risers to the hang-off positions on the Argos FPU in a water depth of 1,380 m (4,527 ft).
The second Mad Dog platform will be moored in the southern Green Canyon area about 10 km (6 mi) southwest of the existing Mad Dog platform, about 306 km (190 mi) south of New Orleans.
ACE Winches said it worked closely with Subsea 7 to simplify and deliver a cost-effective riser installation solution from design through to delivery for both projects.
