Japanese shipping major NYK, compatriot liquefied petroleum gas (LPG) trader and importer Astomos Energy Corporation have held a delivery and naming ceremony for a new LPG dual-fuel LPG/ammonia carrier.
The gas carrier has a length of 229 meters, a breadth of 37 meters, a depth of 22 meters, and a tank capacity of 86,953 cubic meters.
This vessel is equipped with a dual-fuel engine that can use heavy oil and LPG as fuel.
Furthermore, the LPG/ammonia carrier employs a shaft generator that produces electricity by rotating the shaft connecting the main engine to the propeller, enabling the vessel to stop operating the diesel generator during standard navigation and realize full LPG-fueled navigation.
Compared to conventional heavy oil-fueled vessels, SOx (sulfur oxides) and CO2 (carbon dioxide) in the exhaust gas are reduced by more than 95% and 20%, respectively, when the ship is fueled by LPG, according to NYK.
In addition to LPG, the vessel will be able to transport ammonia if future demand increases. Ammonia is attracting attention as a means of realizing a decarbonized shipping sector.
As part of its decarbonization strategy, NYK recently teamed up with its group company MTI Co. and Smert Design to trial the use of a 3D model in the initial design phase of a liquefied petroleum gas tanker.
This trial aims to model 3D design information of existing similar and sister vessels and ease the decision-making by both shipyards and shipping companies for the exchange of requests, ideas, and comments on the same system for the design applicable to this ship.-World Maritime News
