Floating systems may include moored floating surface-based attenuator systems,
point absorbers, floating overtopping systems, etc. These systems convert wave
energy at the surface from a variety of directions. Depending on the system it will
have varying degrees of motional freedom. Both overtopping systems and
attenuators may have relatively complex but ‘flexible’ mooring configurations which
allow them to turn with the dominant wave direction typically across a limited
bearing range that may be as much as 1800. By comparison point absorber systems
are often hinged to seabed whilst still allowing motion of floating surface system
over a more restricted range.
