This dataset represents the provision of 1 ton of transportation service over a 1-kilometer distance by a container ship (deadweight 12,000--15,000 tons) operating in coastal/marine areas. The transportation dataset covers the entire life cycle of transport, including container ship production and maintenance, port construction, energy consumption, and operational emissions.
The average cargo capacity of this bulk carrier is approximately 14,545 tons, with a main engine power of about 2,930 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 load, main engine power, and operational speed. Key emissions (CO2, NOx, SOx, PM, NMVOC, CO, CH4, N2O, etc.) are calculated according to marine fuel consumption and relevant standards. For port infrastructure, data are reasonably extrapolated based on global port-related information.
