The newly developed waste heat recovery system “HydrocurrentTM Organic Rankine Cycle (ORC) Module 125EJW” 1 by Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME) has begun operation on the vessel named Arnold Maersk belonging to Maersk Line.
The ORC system enables the utilization of extremely low temperature heat sources to generate electrical power at low-cost and high-efficiency in marine applications. In concrete terms, the system generates 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, cuts CO2 emissions and improves the efficiency of the vessel’s plant.
The ORC has an output of 125 kW and is fitted to the Arnold Maersk. Prior to this, 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.
Maersk Line is a shipping company based in Denmark’s capital Copenhagen under the umbrella of the world’s largest shipping conglomerate A.P. Moller – Maersk A/S. The Group has offices around the world, and in addition to shipping, operates in areas such as oil, gas and mining.
MHI-MME will continue to offer diverse and creative energy efficiency and environmental solutions to improve the efficiency of shipping, contributing to the reduction of resource use and environmental impact.
