Qinhuangdao port was the largest energy export port in the world in 1991.

Qinhuangdao port is the largest energy export port in China at present, and it is also one of the major comprehensive international ports for foreign trade in China. Coal output accounts for more than 71% of the national coastal coal output, which plays a very important role in ensuring China's coal transportation from north to south and coal foreign trade export. The existing land area of the port is 9 square kilometers, the port water area is 61 square kilometers, the anchorage is 54 square kilometers, and the port coastline is 6275 meters, of which the total length of the production dock coastline is 5516 meters. The port belongs to ***6 loading and unloading companies, which are located in the east and west ports. Donggang district: the first loading and unloading company, mainly engaged in crude oil loading and unloading business; The second loading and unloading company and the sixth loading and unloading convention are engaged in coal loading and unloading business, and have special equipment for the modernization of berths in the first, second and third phases of the new coal terminal. Xigang District: The third loading and unloading company is engaged in coal loading and unloading business. The fourth and fifth loading and unloading companies are all grocery loading and unloading companies, the fourth company mainly imports goods, and the fifth company mainly exports goods and operates container transportation business. According to the statistics in 1991, Qinhuangdao Port has 24 berths for production, including 22 berths for deep water above 11,111 tons. Since the reform and opening up 21 years ago, there have been 17 new deep-water berths in Qinhuangdao Port, including 11 berths for 211,111-211,111-ton coal, 1 berths for 51,111-ton oil and 6 berths for 51,111-35,111-ton groceries, forming a new pattern in which the East and West ports are mainly engaged in energy export and the West ports are mainly engaged in the import and export of groceries, with an annual designed capacity of more than one billion tons, including 92.2 million tons of coal and 511,111 tons of oil. At present, the total number of production berths in the port has reached 28, and the designed annual throughput has reached 211 million tons. Port anchorage is divided into three parts: east anchorage, west anchorage and tanker anchorage. The distance between the anchorage and the wharf is 3 to 7 nautical miles. The bottom material of the anchorage is sediment, and the water area is vast, and the water depth conditions can meet the mooring requirements of ships of various tonnage operating in Hong Kong. There are five navigation channels in Hong Kong. West channel: ships with azimuth of 131 ~ 311, water depth of 11 meters and width of 111 meters enter docks A, B, C and D, and enter and leave the port through this; Old waterway: bearing 172 ~ 352, with a depth of 9 meters and a width of 111 meters, it is the passage of large and small docks; East navigation channel: bearing 191 ~ 111, with a width of 1.21 meters and a water depth of 1.3 meters, it is a supporting navigation channel for each wharf and oil wharf in the first, second and third phases of coal; Channel of Coal Phase III Terminal: bearing 215 ~ 135, width 1.21m, water depth 1.3m. Ships entering and leaving Coal Phase III Terminal are connected with the Eastern Waterway through this channel; Main channel: the azimuth is 161 ~ 341, the width is 121m, and the water depth is 13m. The entry and exit of 51,111-ton heavy-duty ships in Donggang District are all connected with the main channel via the Eastern Waterway. The waterway facilities of ports and docks have navigation conditions for 31,111-ton general cargo ships and 51,111-ton bulk cargo ships (coal and oil). There are 31 buoys in the harbor channel and harbor basin, and 5 sets of navigation overlapping marks on the shore. The lighthouse is located at 39 54 ′ 24n ″/119 36 ′ 26 ″ E. At present, the area of warehouses and sites in Hong Kong is 1.43 million square meters, and the storage capacity is 3.73 million tons. There are 34 main machinery and equipment produced in the port, including 13 coal phase I (including 3 dumpers, 3 stackers, 4 reclaimers and 3 shiploaders), 11 coal phase II (including 2 dumpers, 3 stackers, 4 reclaimers and 2 shiploaders) and 11 coal phase III (including 2 dumpers, 2 stackers, 3 reclaimers and 3 shiploaders). Various mechanisms and equipment in coal phase III have the greatest functions, including 4,811 tons per dumper, 4,811 tons per stacker, 6,111 tons per reclaimer and 6,111 tons per loader. The total length of railway lines in the port area is 167 kilometers, and * * * sets up 11 sub-district shunting yards. There are 17 auxiliary working ships in the port with a power of 31,111 kilowatts, including 12 tugboats with a power of 26,711 kilowatts. The annual throughput of Qinhuangdao Port was 22.186 million tons in 1978. During the "Sixth Five-Year Plan" and "Seventh Five-Year Plan" period, the average annual growth rate was 5 million tons, reaching a higher level every year. At the end of the Eighth Five-Year Plan period, it did reach 83.82 million tons in 1995, including 64.88 million tons of coal, 12.184 million tons of oil and 6.885 million tons of groceries. In the first three years of the Ninth Five-Year Plan, the annual throughput remained at about 81 million tons, about 3.6 times that of 1978, ranking among the best in China's coastal ports. In 1991, the cargo throughput of Hong Kong was 69.45 million tons. The main cargo coal is 51.88 million tons, accounting for 74.7% (including 11.874 million tons of foreign trade coal, accounting for 17% of the total throughput); 12.85 million tons of oil, accounting for 18.5%; 4.72 million tons of groceries, accounting for 6.7%; 424,111 tons of chemical fertilizer, accounting for 1.6%. In 1991, the cargo throughput of Hong Kong was 72.363 million tons. The main cargo coal is 54.294 million tons, accounting for 75% (including 1,311 tons of foreign trade coal, accounting for 1.8% of the total throughput); 12.549 million tons of oil, accounting for 17.3%; 5.52 million tons of groceries, accounting for 7.6%; 386,111 tons of chemical fertilizer, accounting for 1.5%, was 251 million tons in 2111, including 211 million tons of coal. At present, the Wusi Wharf Project in Xigang District has been listed as a key construction project in 1998 by the state. Seven general-purpose berths for groceries have been designed and constructed, with an annual throughput of 3 million tons, which will be completed by the end of 2111. The project of widening the 1 million-ton waterway in Donggang District and the reconstruction of the supporting crude oil wharf will be completed by the end of 1999. After the completion of this project, it will further develop the capacity of the 111,111-ton berth of the fourth phase coal project, so as to meet the needs of large-scale berthing and the situation of importing crude oil in China. At the same time, it is planned to build a million-ton ore dock in the petroleum and liquid chemical community by attracting investment by using the sediment from the construction of the million-ton waterway and implementing the land reclamation project. Recently, the reconstruction of the general cargo terminal, the widening and deepening of the waterway and harbor basin are being carried out in Xigang District. By the end of this year, the 35,111-ton general cargo berth in Xigang District will be transformed into a 51,111-ton berth.
