Jee carried out the Detailed Design for two flexible water injection pipelines and associated umbilicals in Ghana. With a water depth of 1400m, all subsea connections were designed to be diverless.

The scope of work included:

  • In-place analysis of the pipelines and umbilicals - routing, bottom roughness, walking and buckling assessment.

  • Mechanical design of the diverless rigid tie-in spools with integrated lifting yoke.

  • Verification of the design of various installation aids to be used during the lowering operation.

  • Design of deck support frames for transportation of the diverless tie-in spools.

  • Design of the subsea pressure test manifold.
