A new range of distributed buoyancy modules are launched with patent-pending integrated clamping technology.
DBMs reduce tension and load strain on subsea risers and umbilicals which act as a connecting interface between static structures on the seabed and dynamic floating structures on the surface.
The new range's clamping technology adapts to specific needs and conditions of a riser's operation. It eliminates slippage throughout its operational life.
The new internal clamping mechanism comprises three segments housing nine rubber inserts. These increase surface contact area at the interface between the riser and DBM. Vertical bar retainer rubbers ensure there is no drop-off while the holding bolts are engaged. This also secures clamp element orientation and ensures the clamp cannot misalign around the riser body.
These design features allow DBM deployment where traditional solutions would often fail and also results in a smaller more efficient clamping solution, it's declared.
