BarLatch® Fairlead Chain Stopper and Off Vessel Tensioning (OVT)
Patented underwater fairlead chain stoppers used with the OVT method, which moves mooring tensioning onto installation vessels and off the floater.
Description
The patented Off Vessel Tensioning (OVT) method works with BarLatch® Fairlead Chain Stoppers to remove chain tensioning and handling equipment from the floating unit; tensioning is done from the installation vessel.
