Accelerating Floating Offshore Wind Turbines (AFLOWT)

AFLOWT Interreg_logo

AFLOWT comprises a €31 million ambitious four-year floating offshore wind project. Subject to consenting, it is planned that a full-scale floating wind turbine be deployed for testing off the west coast of Ireland at a Sustainable Energy Authority of Ireland (SEAI) AMETS test site near Belmullet, Co. Mayo. The project is led by the European Marine Energy Centre (EMEC) working in partnership with SEAI, SAIPEM, ESB and multiple other European organisations.


Funding for the project has been secured from Interreg North West Europe to accelerate the uptake of floating offshore wind. The project will demonstrate the survivability and cost-competitiveness of a floating offshore wind technology. It will also support the development of an active supply chain in the region which has some of the strongest wind and ocean resources in the world. The project is the first of its kind at such scale to draw on expertise from right across Europe.

The SAIPEM offshore wind floater, proposed for deployment for AFLOWT, is a pendulum lightweight structure including a submersible floater element.

ESB is supporting the consenting and environmental assessments for the project and will work closely with SEAI on delivering the project.
