Ideol has reported that
the 2 MW Floatgen floating wind turbine exceeded production and availability
expectations in the second half of 2019. During the last six months, the
turbine has more than doubled its power production in comparison with the
first semester, to reach an annual total of 6 GWh.
is installed on Ideol's patented floating foundation, which features
a 5,000 tonne ring-shaped hollow concrete float. The shape is designed
so that water movement within the central opening counteracts the motion
of the floater caused by wave swell and stabilises the structure. It is
anchored by six 220 mm-diameter nylon lines.
Installed 22 km off Le Croisic (Loire-Atlantique) at the SEM-REV test site.
Over the course of two years, the project will be tested under real operating
conditions. It is connected to the French power grid via an underwater
hub that allows up to three prototypes to be connected simultaneously.
This hub is connected to an electrical station onshore via an 8 MW cable,
which is buried under 2 metres of sand and sediment.
Power production was achieved as a result of a time availability exceeding
94.6% in the second semester and an above average capacity factor. During
that same period, the wind turbine faced maximum wave heights of up to
12.5 meters (significant waves of up to 6.5 metres).
The wind turbine remained fully operational throughout the first winter
months, producing power up to 5.5 metres of significant wave height and
up to 24.2 m/s of wind speed.
