Maersk’s Mega Boxships to Feature Mitsubishi’s WHRS

Mitsubishi Heavy Industries’ arm Marine Machinery & Engine Co., Ltd. (MHI-MME) has received an order from Korean shipbuilder Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME) for waste heat recovery systems (WHRS) to be installed on Maersk Line’s eleven 19,600 TEU mega boxships.

The WHRS on order is MHI-MME’s proprietary system for marine use that generates electric power by maximizing recovery and utilization of exhaust gas waste energy from marine diesel engines. With this order, the cumulative number of WHRS units ordered since the system’s market introduction in 2010 is 87.

The WHRS is a system that optimally controls exhaust gas turbines and steam turbines, enhancing fuel efficiency by recovering waste heat across a wide range of engine loads. In this way the system contributes to reductions in environmental impact.

MHI-MME’s WHRS equipment was also installed on Maersk Line’s Triple-E series. The new WHRS order will bring the number of installations on Maersk vessels to 69, in four series.
