摘要：There is provided a tensioning device (1) for pretensioning mooring lines inaccordance with the tension-in-a-bight purchase principle. The tensioning device (1) islocated at the bight of the mooring lines (17, 18, 19) and includes a link catching device(6A, 6B) comprising inclined land surfaces (7) and a catching tooth (8) at the lower end ofthe land surfaces (8) which catching device (6A, 6B) catches a link (L1), the caught link, oflink chain during heaving up on a riser chain section (17) so enabling said pretensioning tobe achieved in the mooring line (18, 19). Slots (9A, 9B) are provided in the tensioningdevice adjacent the land surfaces (7) such that the downline link (L2) threading the caughtlink (L1) and the following downline link (L4) each have a significant degree of pivotalfreedom to preclude bending moment loading in these links during heaving up on theriser line (17) during tensioning.
