The dataset represents the transportation service of 1 ton by a tanker for liquid goods (approximately loading 15000 DWT) over a distance of 1 kilometer in China's coastal/marine areas. The transport dataset pertains to the entire transport lifecycle, including the production and maintenance of the tanker for liquid goods, the construction of ports, as well as energy use and operational emissions. The DWT (deadweight tonnage) of this tanker for liquid goods is 15147 tons , with a main engine power of approximately 3970 kW, both values are in reference to the standards for marine vessels in China. Fuel consumption is calculated based on the ship's load capacity, main engine power, and operating speed. The main emissions (CO2, NOx, SOx, PM, NMVOC, CO, CH4, N2O, etc.) are calculated based on mirine vessel fuel consumption and relevant standards. For port and canal infrastructure, reasonable extrapolations are made based on global port information.
