This dataset represents the provision of 1 ton-kilometer freight transport service by dry bulk carriers (deadweight >=150,000 tons) in coastal and offshore areas. The transportation dataset covers the entire life cycle of transport, including dry bulk carrier production and maintenance, port construction, and energy use and operational emissions. The DWT (deadweight tonnage) of the dry bulk carrier is no less than 150,000 tons, with an average cargo load of 180,403 tons and a main engine power of approximately 18,660 kW, values referenced from Chinese marine vessel standards and related sources. Fuel consumption is calculated based on the vessel's average cargo load, main engine power, and operational 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.
