Exhaust Gas Waste Energy News

The push to outfit commercial vessels with energy saving equipment continues, and news out of Japan says that a Mitsubishi Energy Recovery System (MERS) supplied by Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME) was installed on a VLOC (Very Large Ore Carrier) for the first time. The system is designed to enhance power generation efficiency by maximizing recovery and utilization of exhaust gas waste energy from marine diesel engines, and demonstrated significant fuel consumption improvement compared with existing ships during at-sea trial.

The car carrier that mounts the world first Hybrid Turbocharger with Electric Assist function and Variable Turbine Inlet (VTI) ran its sea trial from April 17-22 and proved the world's first electric-assist turbocharger function on actual ship. The turbocharger was manufactured by Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME). By using the electric-assist function, the ship will be able to save energy consumption substantially at slow steaming by reducing the amount of time of auxiliary blower operation. The turbocharger combines the function of electric generation as a hybrid turbocharger and that of VTI in addition to the electric assist function. This ship is a car carrier built by Shin Kurushima Dockyard Co., Ltd.
