Abstract
There is provided a tensioning device for pretensioning mooring lines in accordance with the tension-in-a-bight principle. The tensioning device is located at the bight of the mooring lines and includes a link catching device comprising inclined land surfaces and a catching tooth at the lower end of the land surfaces, which catching device catches a link, the caught link, of link chain during heaving up on a riser chain section so enabling the pretensioning to be achieved in the mooring line. Slots are provided in the tensioning device adjacent the land surfaces such that the downline link threading the caught link and the following downline link each have a significant degree of pivotal freedom to preclude bending moment loading in these links during heaving up on the riser line during tensioning.
