This weeks interesting ship is NYK Lines’ 180,000 DWT bulk carrier, Shin Koho, which was recently delivered at the Tsu Shipyard. What makes this vessel interesting, is that the Shin Koho is the world’s first carrier to be fitted with a hybrid turbocharger.
A turbocharger is a device that turns a turbine at high speed by utilizing exhaust gas from the main engine, then drives a compressor by the turbine, and finally supplies combustion air to the engine. While utilizing 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, the hybrid turbocharger utilizes 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 and by reducing the use of the diesel generator, the hybrid turbocharger contributes to a further reduction of CO2 emissions.
The technology was jointly developed by four companies: NYK, the Monohakobi Technology Institute (MTI), the Universal Shipbuilding Corporation, and Mitsubishi Heavy Industries, Ltd.
