One year after the demonstration of the first functional scale prototype of the Ocean Grazer, the first prototype suitable for wave tanks has been launched.

In preparation of future wave tank trials, a small-scale wave flume has been constructed to experiment with and optimize the current prototype. The device consists of ten interconnected floater members that gradually extract energy from a passing wave. Each floater is connected to an individual piston-type hydraulic pump that displaces water between a lower and an upper reservoir. 

During the open day visitors could attend a demonstration of the first wave tank experiments and were informed about ongoing research. During the first experiments the device already showed great potential by absorbing most of the incoming wave energy for various wave types.

In the coming months several experiments will be performed with the prototype in order to validate numerical models of the system and to optimize the prototype for larger wave tank facilities.
