Service area
Subsea Engineering
Subsea systems design from pre-FEED and FEED to detailed design: field layout, pipelines, risers, structures and components.
Our subsea engineering services cover every stage of a project, from pre-FEED and FEED to detailed design. The deliverables depend on your expectations and the project’s overall EPCI schedule, and draw on many engineering disciplines.
A pre-FEED study finds a general development solution and addresses the main challenges without going into detail. A FEED study resolves the uncertainties and recommends a robust solution, mature enough that no major change follows, because procurement of long-lead items has to start by the end of FEED on fast-track projects. Detailed design then addresses every engineering issue in full, and construction and installation are finalised from its reports and drawings.
