A Maersk Line containership, the Arnold Maersk, has become the first recipient of a newly developed waste heat recovery system, the “Hydrocurrent Organic Rankine Cycle (ORC) Module 125EJW” 1 by Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME).
The ORC system enables the utilisation of extremely low temperature heat sources to generate electrical power at low-cost and high-efficiency in marine applications. It has an output of 125 kW, generating the electricity using the waste heat of the main engine jacket cooling water (approx. 85°C), and by reducing the load on the vessel’s main generator. Therefore it reduced fuel consumption, lowers CO2 emissions and improves the efficiency of the vessel’s plant.
Prior to being fitted on the Arnold Maersk, a pilot ORC machine completed performance testing at the factory of Calnetix Technologies who is a partner of MHI-MME, gaining the approval of ClassNK and Lloyd’s Register of Shipping in 2015.
