Piston Engine Room Free Efficient Containership (PERFECt)
In late 2015 GTT, CMA CGM (and its subsidiary CMA Ships) and DNV GL released a technical and feasibility study for a new mega box ship – the Piston Engine Room Free Efficient Containership PERFECt. The concept vessel is LNG-fuelled, powered by a combined gas and steam turbine, and is electrically driven. The feasibility study established that technically and economically, a COGES-powered electric ship was worth a more detailed study. In 2016, ABB as expert in electric propulsion, OMT as naval architect, and Caterpillar’s Solar Turbines as the COGES supplier joined the consortium. Exploring this novel configuration resulted in the partners identifying and analyzing a propulsion concept that has the potential to offer a more efficient, more flexible and greener box ship design than current 20,000 TEU two-stroke diesel engine driven ultra large container vessels.
