Abstract

A SALM (single anchor leg mooring) terminal is described, of the type which includes apparatus mounted on the moored vessel for applying tension to the anchor leg so as to avoid the need for a large float at its upper end, which is of simple and reliable construction and which occupies little or no space on the permanently moored vessel. The system includes a yoke having a middle portion pivotally connected to the moored vessel, an inner end connected to the top of the anchor leg, and an outer end which lies outboard of the ship and which carries a counter weight, so that downward force applied by the counter weight produces an upward force on the anchor leg. By mounting the counter weight outboard of the vessel, large up-and-down swinging movement of the yoke can be accommodated without drastic modification of the vessel, and a simple pivoting system can be utilized to apply the necessary tension to the anchor leg.
