Abstract
A series of experimental tests are reported which concern the viability of capturing power from regular and irregular waves by restraint of a wave radiating body oscillating in surge. The effect of hull form and mechanical properties of the restraint on power captured through damping are investigated and the relationship between these parameters and the design requirements of a power take off system are discussed. The results show that an asymmetric plate with one convex and one concave face attains good mean power capture in a range of wave fields.
