ABSTRACT:
An offshore mooring buoy for mooring a crude oil tanker and the like includes a hawser tension sensing member and a control circuit for generating indicator signals in response to predetermined mooring tension forces exerted on the buoy under varying sea conditions. A mast mounted on a mooring platform of the buoy includes a vertically-spaced array of colored indicator lamps which provide visual indication to the ship's crew of a range of acceptable, stand-by, and unacceptable mooring loads exerted on the buoy and the hawser. The circuit is also operable to energize a horn when a predetermined sustained mooring force is exerted on the buoy as a back-up signal or when weather conditions impair visual observation of the indicator lamps.
