Attenuator

Floating device that operates parallel to the wave direction.

Surface attenuators generally have multiple segments connected to one another and that are oriented parallel with incoming waves. They use the rise and fall of swells to create a flexing motion that may be converted into rotation or drive hydraulic pumps to generate electricity. Some attenuator designs consist of a single long, flexible surface expression instead of multiple segments.
