Abstract
The Waveram is a spar type heaving point absorber with adjustable mass, spring[CS1], and PTO damping intended to operate effectively in a changing environment using autonomous control. It is a single rigid structure reacting against the sea surface, a configuration not previously considered. Being a single body removes engineering challenges such as hinges, alignment and end-stops. The concept has been tested at scale previously and this data used for initial calibration of simulation models. This test series seeks to assert the efficacy of the simulation models by providing a second data set away from the calibration point.
