Resumen de: AU2024279911A1

A buoyant offshore renewable energy system mounting platform is provided for use in supporting a renewable energy system in a body of water. The platform comprises a buoyant spar having a top end and a bottom end, the spar arranged to support a renewable energy system thereon; and a plurality of mooring lines arranged to tether the spar to a bed of a body of water such that the buoyant spar is positioned in the body of water at an operating depth. The plurality of mooring lines comprise: one or more first mooring lines affixed to a bottom end of the spar, the bottom end distal to the top end, and arranged to engage the bed of the body of water; and at least three further mooring lines, a first end of each of the further mooring lines being in communication with the spar between the top end and the bottom end thereof, and a second end of each further mooring line being arranged to engage the bed of the body of water such that said further mooring line is oriented diagonally relative to the spar at the operating depth; wherein at the operating depth, the first end of the spar is positioned above a surface of the body of water and the second end is positioned below the surface of the body of water. The described platform aims to provide a simple and stable offshore renewable energy system mounting solution having a simpler manufacture, assembly and deployment procedure along with easier ongoing access for deployment and maintenance vessels to minimise damage during deployment an
