SEA Global completed engineering across the define phase, FEED, detailed design, and execution support for a 19 km, 20-inch pipeline transportation system.
The scope of work encompassed steady-state and transient thermohydraulic flow assurance modeling to confirm expected performance, detailed engineering for the pipeline system, and structural design for two subsea PLEMs with piled foundations and spools supports. It also involved developing integrated solutions for floating systems, including riser configuration and mooring design. Furthermore, the team managed material selection, procurement tender evaluations, technical support for the partial replacement of aged infrastructure, and the design of subsea spools, connection hardware, and commissioning strategies.
