董家口港40万吨级矿船套泊作业关键要素确定

为进一步提升青岛港董家口港区矿石码头泊位通过能力、提高卸船作业效率，在当前董家口港区矿石泊位使用率居高不下以及无新增码头投建的背景下，考虑2艘40万吨级矿船在吃水受限港池进行套泊作业的高风险系数，基于船舶操纵模拟试验，仿真40万吨级矿船在不同风、浪、流工况组合条件下进行套泊作业试验，并根据试验结果确定40万吨级矿船套泊作业的关键要素。结果表明，在确定的套泊作业关键要素条件下，董家口港区可安全进行40万吨级矿船套泊作业。

Determination of key elements of 400, 000-ton ore ship mooring operations in Dongjiakou Port

In order to improve the berth throughput capacity of the ore wharf in Dongjiakou Port area of Qingdao Port and enhance the efficiency of unloading operations, this paper considers the high risk factor for two 400, 000-ton ore ships to conduct mooring operations in a port with a limited basin under the background that the utilization rate of the ore berth in Dongjiakou Port area is currently high, and no new wharf is built. Based on the ship maneuvering simulation test, the paper simulates a mooring operation test of the 400, 000-ton ore ships under different conditions of wind, wave, and current and determines the key elements of 400, 000-ton ore ship mooring operations according to the test results. The results show that under determined key elements of mooring operations, Dongjiakou Port area can safely carry out the 400, 000-ton ore ship mooring operations.
