A disconnectable mooring system 11 for offshore semi-submersible floating structures 4. A disconnectable buoy 24 has a number of mooring lines 20a-c which include a buoy chain 22b between the mooring chain and the buoy. The mooring chain and the buoy chain are connected via a mooring connector 18. In a first configuration (Fig 3b) the buoy is disconnected and supports the mooring chains for recovery at shallow depths to be pulled in. In a second configuration (Fig 2b), the mooring lines are pulled in via the mooring connectors and the buoy chain is left as a catenary between the buoy and mooring point to thereby provide a spread mooring.
