An anchoring assembly for maintaining an acceptable position of a floating vessel such as a drilling platform 10 over a fixed point at the sea bottom comprises one or more mooring elements 22 having a positive buoyancy with respect to seawater. Each buoyant element 22 extends in use in a substantially inverted catenary arc from an anchor 24 to the platform 10. The mooring elements 22 provide restoring forces against the forces of wind, wave and current action which tend to offset the floating vessel from the desired mooring point. IMAGE
