A mooring system for a floating electric power producing unit 24, such as a wind turbine or a wave energy converter, comprises a buoyant element 10 held beneath the surface and a swivel (38, Fig 1) supported by the buoyant element. The swivel comprises a static part (40, Fig 1) that is held against angular movement about an upright axis and a rotating part (42, Fig 1) that is movable angularly relative to the static part about the upright axis. A mooring link 28 extends between the power producing unit and a mooring point (46, Fig 1) supported by the buoyant element. A conductor link 30 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. A method of mooring a floating electric power producing unit to a sub-surface buoyant element is also disclosed.
