DSME has placed an order with Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME) to supply the ships with its proprietary system for generating electric power by maximizing recovery and utilization of exhaust gas waste energy from marine diesel engines.
The systems ordered for the Maersk newbuildings takes the total number of MHI-MME's WHRS units ordered to 87 since the system's market introduction in 2010. Maersk has thus far been the biggest customer the system, with 69 units ordered for installation in four series of ships, including its 18,300 TEU Triple-E vessels.
The WHRS is MHI-MME's best-selling product and the company holds a greater than 90% share of the WHRS global market.
