Chain Tensioning

We provide Vryhof STEVTENSIONER® for proof loading of a permanent mooring system for CALM buoys and FPSOs.

The proof loads are typically 80-100% of the design load so that substantial bollard pull capacity is required. The use of the STEVTENSIONER® for subsea tensioning offers significant cost benefits as it reduces the required load by typically 60%. As a result mooring installations can be performed from modest anchor handlers or crane barges.
