©ELISA technology uses a gravity foundation (GBS) for marine wind power, configured to act as a floating platform to enable the substructure and wind turbine (WTG) to be installed together. Each complete unit — the GBS and the WTG — is fully assembled on land and then towed conventionally to the final site, where it is installed using low-cost means (tugboats). The ©TIM platform is used to assure a high degree of stability throughout the towing and ballasting process. It can be coupled firmly to the concrete GBS shaft to hold them together while afloat.

If a vessel with a Jack-up platform is available at a competitive price, ELI technology is a competitive alternative. The ELI concept maintains the gravity foundation designed to act as a floating platform and the first section of the tower at the access-platform level. It is also installed with a small-scale ©TIM in order to optimise the use of materials for the foundation. In this case, the steel tower and the WTG are installed in the conventional way with a vessel equipped with a jack-up platform.

©ELI and ©ELISA provide a viable substructure system for a wide variety of marine wind farms in deep waters (15–70 m), particularly in certain specific conditions such as a rocky sea bed or in emerging markets where the supply chain is not fully established.

ELICÁN

Project for the construction and installation of the offshore wind turbine prototype for the pioneering ELISA technology, developed and patented by ESTEYCO.

First marine turbine fixed to the bottom of southern Europe, and the first in the world to be installed without the need for heavy-lift vessels.
