NYK takes delivery of vessel with world's first hybrid turbocharger

NYK recently took delivery of a new 180,000 DWT bulk carrier, Shin Koho, at the Tsu Shipyard of the Universal Shipbuilding Corporation, according to Exim News Service.
Shin Koho is the first carrier in the world to be fitted with a hybrid turbocharger, which was jointly developed by four companies: NYK, the Monohakobi Technology Institute (MTI), the Universal Shipbuilding Corporation, and Mitsubishi Heavy Industries, Ltd. The vessel will transport iron ore from Australia and other countries.
A turbocharger is a device that turns a turbine at high speed by utilising exhaust gas from the main engine, then drives a compressor by the turbine, and finally supplies combustion air to the engine. While utilising waste energy, a turbocharger boosts the output power of the engine by enabling it to aspirate at a level higher than that for the original engine displacement.
In addition to these basic functions, a hybrid turbocharger utilises the extra rotational power generated by the turbine for electric power generation.
Shin Koho can meet all its onboard electric power requirements for normal operation by using a hybrid turbocharger instead of diesel generators. By reducing the use of the diesel generator, the hybrid turbocharger contributes to a further reduction in CO2 emissions. (source: transportweekly)
