The STEVADJUSTER® is an innovative, cost-effective and time-saving solution for chain adjustment, pre-tensioning of moorings and easy connection or disconnection of anchor lines. The entire operation takes place subsea and does not require the use of winches or other heavy equipment on the platform being moored. Therefore, the bollard pull of the vessels involved in the operation does not need to be prohibitively high. Modest installation or maintenance vessels have sufficient capacity to get the job done. The use of this subsea chain adjuster offers significant safety benefits, as the tensioning operation is performed away from the floater.
