Our marine team designed a solution which comprised of 48 strings of buoyancy modules (288 individual units). Each string was constructed from six moulded polyethylene shells filled with PU foam and assembled on a steel fabrication, each providing 3.9 tonne of buoyancy and rated to 350 msw. The buoyancy module strings feature a mooring/lifting eye at each end, where they will be attached vertically from a pipeline to provide support to a length of subsea pipeline whilst it is being repaired.

We achieved our customers time frame by utilising our in-house equipment, providing regular communication and implementing a smart design idea. This meant the modules could be packaged/transported easily and economically. These initiatives allowed us to meet the short lead time of ten weeks from placement of order to completion.
