Abstract
A fairlead for guiding an anchor chain, intended to equip a ground anchor system for a floating platform, includes a bending structure for guiding a direction change of the associated anchor chain, and a locking structure that includes a grip jaw consisting of two jaws associated with operating elements for rotatably moving the jaws in opposite directions. The operating elements include: (a) an inert mass, referred to as “counterweight”, which is movably coupled to the jaws and which is height-adjustable between a low position and a high position corresponding to an active position and an inactive position of the jaws, respectively, so as to operate and tend to maintain the jaws in the active position, and (b) an actuator driven by control elements, for operating the jaws from the active position to the inactive position and for operating the counterweight from the low position to the high position.
