Attenuators are long, multi-segmented structures that float parallel to the direction of the wave. As a wave passes, it causes the structure to bend at the segments; this bending motion is converted to electricity.
<ref> http://cwec.ucdavis.edu/forum2011/proc_open/Forum2011_Caliendo.pdf</ref>Point absorbers are floating structures that have that are moved by wave action. One component is moved by the wave while the other is stationary. This relative motion drives devices that convert movement into electricity.
====Oscillating Water Column====
Oscillating Water Column devices extend perpendicular to the direction of wave travel and capture or reflect the power of the wave. Water enters through a subsurface opening into a chamber with air trapped above it. The wave action causes the captured water column to move up and down forcing the air though an opening connected to a turbine.
