These are two 323.8 mm (12in) by 33 km and 21 km long lines containing untreated well fluids, and a 404.6 mm (16in) by 17 km long export gas line.
This preliminary front-end engineering design (FEED) study used preliminary reservoir and platform process information to determine the diameter, wall thicknesses and concrete weight coating for the three lines linking one manned two and normally-unmanned platforms to deliver the export gas to a tie-in on an existing line to shore.
The investigation examined the stability of the seabed sediments in the area, the need for trenching and likelihood of self burial.
At the client’s request, the bulk of the conceptual study was completed within the first three weeks, with further clarification of the design in the following few weeks.
The front-end engineering conceptual design study also included
