Abstract
A waterborne barrier which includes an elongate array of buoys which are connected together by tamper-proof couplings, wherein each buoy has a buoyant body which is rotatable about a central axis and which is formed from expanded plastics material in a circular cylindrical plastics shell, with a reinforcing structure embedded in the plastics material.
Claims24
A buoy comprising a buoyant body and a reinforcing structure in or on the buoyant body.
A buoy comprising:
- a buoyant body of circular cylindrical form;
- spaced apart first and second supporting members each of which is centered on an axis;
- a reinforcing structure positioned between the first and second supporting members and secured to the first and second supporting members;
- and buoyant material, wherein at least a part of the reinforcing structure is embedded in the buoyant material.
A method of forming a buoy for use in a waterborne barrier, the method comprising:
- providing a reinforcing structure configured to resist attack;
- positioning the reinforcing structure within an interior of a mould such that the reinforcing structure is spaced inwardly from an opposing surface of the mould;
- and introducing an expansible buoyant material into the interior of the mould so that at least a portion of the reinforcing structure is embedded in the buoyant material when it sets to form a buoyant body.
A waterborne barrier including an elongate array of buoys connected together by tamper-proof couplings, wherein each of the buoys has a buoyant body which is rotatable about a central axis and which is formed of expanded plastics material in a circular cylindrical plastics shell, with a reinforcing structure embedded in the expanded plastics material.
