A mooring system for a floating electric power producing unit such as a wind turbine or a wave energy converter comprises a buoyant element held beneath the surface and a swivel supported by the buoyant element. The swivel comprises a static part that is held against angular movement about an upright axis and a rotating part that is movable angularly relative to the static part about the upright axis. A mooring link extends between the power producing unit and a mooring point supported by the buoyant element. A conductor link extends between the power producing unit and a connector supported by the buoyant element. The mooring point and the conductor link are movable angularly about the upright axis together with the rotating part of the swivel. Angular movement of the mooring link about the upright axis drives corresponding angular movement of the conductor link about the upright axis.
