NYK unveils new ship design to support decarbonisation

Japan’s NYK Group has unveiled a new concept ship crafted as a pure car and truck carrier (PCTC) to promote decarbonisation.

Japan’s NYK Group has unveiled a new concept ship crafted as a pure car and truck carrier (PCTC) to promote decarbonisation.

The new NYK Super Eco Ship 2050 features innovative technologies to support the development of an emission-free vessel.

Created as part of the company’s medium-term management plan, ‘Staying Ahead 2022 with Digitalisation and Green’, NYK Super Eco Ship 2050 is an updated version of NYK Super Eco Ship 2030, which was created in 2009.

Both the designs were developed by NYK in collaboration with Japan-based MTI and Finnish engineering and consulting company Elomatic.

NYK Group said in a statement: “The power needed to operate the ship has been cut by 70% by remodelling the hull to decrease water friction, reducing the weight of the hull, introducing fuel cells for electric propulsion, and relying on other highly efficient propulsion devices.”

In order to reduce the power required by the vessel to operate, NYK has employed a mathematical design to reduce the weight of the hull.

The company has also installed computer-controlled devices such as gyro stabilisers to provide active stability for the lightweight vessel hull.

“All these sources of power could help the vessel completely eliminate carbon dioxide (CO2) emission and make way for a zero-emission operation.”

An air-lubrication system has been installed to reduce the frictional resistance between the vessel’s bottom and the seawater with the help of bubbles created by supplying air to the vessel’s bottom.

The vessel features an automatic hull cleaning system to prevent any negative impact on its efficiency during port stays.

NYK has replaced the conventional propellers with flapping foils that imitate the movements of dolphins to increase the efficiency of the vessel’s propulsion.

Instead of fossil fuels, NYK Super Eco Ship 2050 will be powered by solar energy and hydrogen fuel cells produced from renewable energy sources.

The vessel is also designed to operate on waste heat recovered from the fuel cells.

All these sources of power could help the vessel completely eliminate carbon dioxide (CO2) emission and make way for a zero-emission operation.
