The bespoke solution comprises 48 strings of buoyancy modules (288 individual units); each string being 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 350m 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.

The team at Manuplas met the customers’ time frame by utilising in-house equipment, providing regular communication and implementing a smart design idea; ensuring the modules could be packaged/transported easily and economically. The initiatives enabled the short lead time of ten weeks from placement of order to completion to be achieved.

Manuplas is part of Advanced Insulation, an established global leader in the engineering, manufacture and application of insulation and passive fire protection systems, buoyancy and SURF products (subsea, umbilicals, risers and flowlines) to the offshore and onshore oil and gas industry.
