Buoy with buoyant core and collar having multiple flotation components

摘要

The present invention relates to a buoy having a buoyant core component around which is a collar with a plurality of detachable flotation components. Preferably, the flotation components are secured to the core using a downward lip projection around a periphery of the core component and an upward lip projection on the detachable flotation components which engages a recess behind the downward lip component. In preferred embodiments, the buoy is more than 2.5 metres diameter, while the diameter of the core component is 2.35 metres or less. A tie bar assembly and lifting/mooring mounts may be located on the core.
