Ocean Power Technologies (OPT) has signed a new contract with Mitsui Engineering & Shipbuilding (MES) to develop PowerBuoy technology for its application in Japanese sea conditions.

Under the contract, the two companies will develop a new mooring system for OPT’s PowerBuoy, customized for wave power stations off the coast of Japan.

The new system will undergo testing at MES’s wave tank facilities to verify the results of extensive computer modeling.

Work under this agreement is expected to be performed over the next six months.

In October 2009, OPT and a consortium of MES, Idemitsu Kosan and Japan Wind Development signed a memorandum of understanding (MoU) for the development of wave energy in Japan.

Further building on the MoU, OPT and MES intend to complete work on the mooring system and progress the identification of a project site for an in-ocean trial of the PowerBuoy system.

OPT is engaged in wave-energy technology that harnesses ocean wave resources to generate clean and environmentally-beneficial electricity.
