Japan’s shipping company Nippon Yusen Kabushiki Kaisha (NYK) and Monohakobi Technology Institute (MTI), a subsidiary of the NYK Group, have reportedly made energy-saving adjustments resulting in a 23% reduction in carbon dioxide (CO2) emissions over half a year, by remodeling a container ship’s bulbous bow and installing the in-house pre-swirl stator type device MT-FAST.
The 23% reduction in CO2 emissions was subsequently certified by the ship classification society ClassNK. The conversion was also verified not to affect the safe operation of the vessel or the operating condition of the engine.
This adoption of energy-efficient technology is being supported by a grant provided through the Maritime Port Authority of Singapore’s Green Technology Programme and also supported by the ClassNK Joint R&D for Industry Program.
The NYK Group will proceed with construction based on this new approach now that effective methods for these operating conditions have been established.
