Apparatus for guiding and stopping an anchor chain on a floating structure

摘要

An apparatus for guiding and stopping an anchor chain on a floating structure, wherein the chain (13) comprises links (17, 19) forming a catenary plane between the structure and an anchor. Standing chain links (17) and lying chain links (19) are guided by through a mouthpiece (10) with an inner guide passage (14) of generally cruciform cross-section. The standing chain links and the lying chain links are received in pairs of opposite grooves (16, 18) in first and second arms of the cruciform. Each arm has a constant width transversely to the catenary plane but diverges in direction towards the anchor. Link supporting surfaces in the opposite grooves (18) of the second arm cooperate in pairs and have planar surface portions (22) to support individual lying links when the chain (13) is stopped by stopper (12).
