The largest floating wind turbine in the world – an 8.4-megawatt (MW) ABS-classed offshore wind turbine – is about to be installed 20km off the coast of Portugal.
It is the first of three ABS-classed semi-submersible floating wind turbines that will eventually make up a 25MW offshore wind farm.
“Large highly-efficient turbines reduce capital costs as well as operating costs – so the deployment of the world’s largest floating offshore turbine is a significant milestone in this emerging industry,” says Matt Tremblay, ABS senior vice president, Global Offshore.
“As the world’s leading offshore classification organization, we are able to leverage our extensive experience with the oil and gas sectors to support safety and innovation in the offshore wind industry.”
Floating offshore wind farms are not subject to the same depth restrictions as fixed structures and can be at any depth.
With the development of larger turbines and research focused on shallow water moorings, floating technology may become an alternative to traditional bottom- founded technologies in intermediate water depths in the future.
ABS is the leading class society for floating offshore wind and developer of design standards and concepts for floating offshore wind turbine foundations.
It certified the first commercial-sized semi-submersible floating offshore wind turbine – WindFloat 1 – in 2011 and released the ABS Guide for Building and Classing Floating Offshore Wind Installations in 2013.
