Mitsubishi Heavy Industries, Ltd. (Mitsubishi) Wednesday announced that the first instance of a newly developed bunker saving waste heat recovery system has begun operation on a Maersk Line vessel, Arnold Maersk.

As Ship & Bunker previously reported, the Hydrocurrent Organic Rankine Cycle (ORC) system is said to be able to save up to 200 tonnes of bunker fuel annually, and has been developed by Calnetix Technologies, LLC. (Calnetix), and MHI Marine Machinery & Engine Co., Ltd. (MHI-MME).

"In concrete terms, the system generates electricity using the waste heat of the main engine jacket cooling water (approx. 85degC), and by reducing the load on the vessel's main generator, cuts CO2 emissions and improves the efficiency of the vessel's plant," explained Mitsubishi, noting that the ORC system has an output of 125 kW.

Last June Ship & Bunker reported that the system had gained class approvals fromĀ Lloyd's Register and Nippon Kaiji Kyokai (ClassNK).
