Low-cost substructure system

For offshore wind energy

Bottom-fixed offshore turbine prototype that can be installed safely, simply and without cranes

02

The ELISA technology involves a novel self-floating gravity-based foundation system which integrates an autolift telescopic tower that can be fully assembled at the dock.

The telescopic configuration of the tower brings down the center of gravity during the towed self-floating transport, allowing the bottom foundation platform to temporarily act as a self-stable floating barge over which the complete system can be pre-assembled onshore. This reduces the complexity and risk associated with installing the towers in unpredictable offshore environments. Once ballasted to rest on the seabed, the tower can be lifted to its final position by means of cables and conventional off-the-shelf heavy-lift strand jacks which are used to lift each tower level successively. All works are carried out from a single access platform.

Key features

  • 30% carbon footprint reduction
  • Solutions for the clear market trend towards increase water depth (>35m) and increased turbine size (5-8MW and 10+ MW coming in the very near future)
  • Can be towed into position using readily-available tugboats instead of scarce and expensive dedicated transportation vessels
  • Low impact on seabed (morphology, sediments), moderate impact on marine ecosystem
04

Profitability

  • 30% cost reduction relative to conventional methods: lowers the barriers to entry and makes the cost of equity (COE) more affordable
  • Manufacturing and commercialising offshore wind turbines revitalises industrial sectors and increases employment rates.
