This dataset describes the provision of transport services for one twenty-foot equivalent unit (TEU) over a distance of one kilometer in coastal/marine areas using a container ship with a capacity of 2,000 TEU. Port throughput refers to the total volume of cargo transported in and out of a port area by water and handled during a certain period, typically measured in twenty-foot equivalent units (TEUs), with one standard container measuring 20 feet in length * 8 feet in width * 8.6 feet in height (6.1 m * 2.44 m * 2.59 m, 38. 55 m³); when using this dataset, it can be converted according to the actual freight transportation conditions. The container ship has a capacity of 2,000 TEUs, and fuel consumption and major emissions (CO₂, NOx, SOx, PM, NMVOC, CO, CH₄, N₂O) are calculated based on the vessel's load capacity, main engine power, and operating speed. When modeling and selecting container transport for cargo, this dataset can be used as follows: for example, if your cargo volume is 1 m³, you need to convert it into TEU units, using the conversion rate 1 m³ = 0.02594 (1/38. 55 TEU
