The Stage 2 NetBuoy project encompassed two areas Tension Technology International Ltd (TTI) sees as being key to the path towards cost competitive wave energy – impermeable fabrics to provide compliant and thus load shedding/peak load resistant buoyant modules, and fibre rope ‘load nets’ to encapsulate the buoyant modules, applying distributed restraint loads and agglomerating the distributed load back to a single or number of structural points to connect to the other parts of the WEC system such as the PTO. 

The medium-sized NetBuoy100 was ultimately chosen for more detailed engineering and cost assessment. This was benchmarked against a steel equivalent buoy to demonstrate the cost benefits and potential impact on LCoE (Levelised Cost of Energy), using the WES costing tool.

This team is currently undertaking a Stage 3 project.
