TÜV SÜD lends hand to ESTEYCO

TÜV SÜDActing on behalf of Spanish civil engineering and consulting firm ESTEYCO, TÜV SÜD is supporting the design and development of foundations for offshore wind turbines in the ELISA and ELICAN projects funded by the European Union.

A pilot turbine was installed off the eastern coast of Gran Canaria in June 2018. TÜV SÜD experts have accompanied the project from design examination to pilot-turbine Installation. 

Within the scope of the
ELISA and ELICAN projects, an industrial consortium under the leadership of ESTEYCO is developing a support structure for offshore wind turbines to be used in deep water.

The combination of a telescopic tower and a concrete foundation which acts as a self-buoyant platform during transport cuts the installation costs of offshore wind turbines so TÜV SÜD say.

The entire structure can be assembled from precast and in-situ concrete elements in the dry dock. During sea transport, the foundation acts as a floating body. The telescopic tower is retracted to ensure a low centre of gravity and improve the platform's floating stability.

During installation, the foundation is lowered and the telescopic tower extended. Transportation and installation do not require usage of special installation vessels and cranes. The
ELICAN prototype of the support structure is designed for a wind turbine with a capacity of 5MW. The two projects, ELISA and ELICAN, are funded by the European Union within the Horizon 2020 programme.
“We are very pleased that ESTEYCO are trusting in our expertise and experience for this complex and exciting project”, says Florian Singer, project manager of TÜV SÜD Industrie Service GmbH.

Within the scope of the
ELISA and ELICAN projects, TÜV SÜD's employees examine the design of the concept and provide inspection and monitoring services during prototype installation.

Examination of the design and support structure and of static and dynamic analyses requires close collaboration between naval architects and experts in load analysis of wind turbine structures and concrete structures.
