This dataset represents the transportation service of providing one ton-kilometer for a dry bulk carrier (deadweight 80,000 tons) operating in coastal and offshore areas. The transportation dataset covers the entire life cycle of shipping, including the production and maintenance of the dry bulk carrier, port infrastructure construction, as well as energy use and operational emissions.
The dry bulk carrier has a DWT (deadweight capacity) of approximately 80,000 tons and a main engine power of approximately 11,620 kW, values referenced from Chinese maritime vessel standards and related sources. Fuel consumption is calculated based on the ship's load capacity, main engine power, and operating speed. Major emissions (CO2, NOx, SOx, PM, NMVOC, CO, CH4, N2O, etc.) are calculated according to marine fuel consumption and relevant standards. For port infrastructure, data is reasonably extrapolated based on global port-related information.
