Retrofit Jacket Clamp Design

Scope

Retrofit subsea riser clamps were required to support the GWF riser on the Goodwyn A jacket.

Risers were to be adjustable and facilitate installation by divers and not overstress jacket members.

Refer to project 029 Riser.

 

Outcome

 

Cube was engaged to design clamps to support the GWF 1 retrofit riser on the Goodwyn jacket.

Using loads from the riser analysis, the clamps were assessed to determine the required:

  1. clamp and bolt size/numbers to resist the applied slip & separation forces, in accordance with ISO 19902.
  2. clamp plate & weld thicknesses for code compliance with AISC 350-05.

In addition, Cube performed a jacket substrate member integrity check in accordance with ISO 19902.

Refer to project 029 Riser.
