This dataset represents the transportation service of 1 ton-kilometer provided by a container ship (deadweight 15,000--20,000 tons) operating in coastal/marine areas. The transportation dataset covers the entire life cycle of transport, including container ship production and maintenance, port infrastructure construction, as well as energy consumption and operational emissions.
The average cargo capacity of this bulk carrier is approximately 18,500 tons, with a main engine power of about 3,677 kW. These values are based on Chinese maritime vessel standards, shipbuilding certificates, and related documentation. Fuel consumption is calculated based on the vessel's average cargo capacity, main engine power, and operational speed. Major emissions (CO2, NOx, SOx, PM, NMVOC, CO, CH4, N2O, etc.) are calculated according to fuel consumption of marine vessels and relevant standards. For port infrastructure, data is reasonably extrapolated based on global port-related information.
