The fairlead comprises a fairlead frame, a pivoting latch, and an actuator. The fairlead frame is pivotally mounted to the offshore structure and supports an axle for a chain sheave. The pivoting latch is mounted to pivot on the axle and comprises a tension link with a chain latch and a counterweight for urging the chain latch into engagement with the chain. The pivoting latch is configured to engage the chain only when the chain is traveling in the payout direction. The actuator controls the action of the counterweight. La presente invencion se refiere a una guia para dirigir y sujetar una cadena de ancla entre una estructura mar adentro y una ancla. La guia comprende un bastidor de guia, un pestillo pivotante y un accionador. El bastidor de guia se monta pivotante en la estructura mar adentro y sostiene un eje para una garrucha de cadena. El pestillo pivotante se monta para girar en el eje y comprende un eslabon de tension con un pestillo de cadena y un contrapeso para desplazar el pestillo de cadena en acoplamiento con la cadena. El pestillo pivotante se configura para acoplar la cadena solo cuando la cadena recorre en la direccion de desenrollado. El accionador controla la accion del contrapeso.
