Flotation
Mooring Buoys
Fabricated Steel Admiralty Pattern
Mooring Buoy
Fabricated from 8mm steel plate and constructed with
watertight compartments (2 for 5th and 6th Class and 4
for the remainder) each with a manway and drain plug.
Admiralty pattern mooring buoys are finished with
rubber or timber fendering and life chains.
The central open hawse pipe, with reinforced collars
at each end, allows for a large diameter riser chain
to be lead through the buoy, ensuring all loads are
transmitted directly to the mooring itself and not
to the buoy.
