The experiments were carried out with a torus shaped buoy,
assembled together from six sections, see Fig 3. It was equipped
with a line force measurement system, consisting of a force transducer,
battery, data logging and transmission system and an antenna.
A tripod connects the buoy to the connection line which, in
turn, connects to the generator. The volume of the buoy was
13.4 m3 and it had a total weight of 3500 kg.
