NYK partners with MTI to reduce containership emissions

The fellow NYK Group companies said vessel adjustments reduced CO2 emissions by 23%.    NYK and the Monohakobi Technology Institute, an NYK Group company, worked together to develop energy-saving adjustments to a containership that resulted in a verified 23 percent reduction in carbon dioxide (CO2) emissions, according to a statement from NYK.
   The ocean carrier did not release specific details of the adjustments, but said that it will “aim for further energy savings by containerships by proceeding with construction based on this new approach now that effective methods (patent pending) for these operating conditions have been established.”
   To reduce energy consumption, containerships often sail at a speed that is much slower than the average speed anticipated when the ship was designed and built. NYK began conducting research in 2013 to make existing ships more energy efficient at these slower speeds.
   These most recent tests took place over the course of six months beginning in June 2014 and the 23 percent reduction was subsequently certified by the ship classification society ClassNK. ClassNK also verified the changes did not affect the safe operation of the vessel or the condition of the engine.
   The group’s research and adoption of energy-efficient technology is funded by grants from the Maritime Port Authority of Singapore’s Green Technology Programme and the ClassNK Joint R&D for Industry Program.
