Port overstock refers to the situation that the number of ships and goods in the port is too concentrated, which exceeds the maximum throughput and transportation capacity of the port, causing congestion and congestion in the port for a period of time. Most cases of overstock are caused by the concentrated arrival of vessels. At the same time, the adverse weather affecting the progress of port operations is also an objective factor causing the overstock; The key to solving the problem lies in the size and equipment capacity of the port, including the number of berths at the terminal, the capacity of loading and unloading equipment, the capacity of the warehouse site, inland transportation facilities and measures to deal with weather factors in advance.

The following information can be obtained by monitoring the iron ore ships' overstock in the port:

• The main types of ships carrying iron ore are headland bulk carriers and larger tonnage ore carriers. The situation of overstock at the discharging port is directly related to whether the fleet's transport capacity can be released in time. Serious port overstock will cause obvious shortage of transport capacity supply, leading to the rise of freight charges on the mainstream routes of iron ore.
• Iron ore, as the basic raw material necessary for steel production, is also the subject matter of bulk commodity trading; The iron ore overstockedin the port will soon become a supplementary source of goods for the port inventory. Monitoring the situation of port overstock can clearly understand whether the specific port operation is stable and orderly. Combined with the port dredging situation, the port inventory can be estimated for a period of time in the future.

HiFleet can obtain the quantity of iron ore at a specific port by identifying and counting the number of ships carrying iron ore in the anchorage of the port, and estimating their number of ships and cargo volume; Tracing the shipping ports of these iron ores can subdivide the import sources of these goods. As shown in the figure below, it shows the overall fluctuation of iron ore ports overstock across the country in September. It can be seen that the number of ships and cargo quantity after the typhoon "Meihua" landed reached the peak of the month, and the increase of port overstock after the typhoon was mainly reflected in East China ports.

There are many data about port overstock , but there are only two data sources: ship AIS satellite data and port ship list (ship list can be provided by ship agent, freight agent and port). The data channels are complex and diverse, and the credibility is uneven. HiFleet’s "Marine Traffic Filter" can help you to intuitively and conveniently browse the iron ore overstock of each port. HiFleet‘s "Marine Traffic Filter" sets the following screening conditions: ship type, ship status, draught, ship length, ship deadweight, and ship flag.

A well-known researcher shared a simple method of using HiFleet’s "Marine Traffic Filter" to obtain iron ore port overstock. In the "Marine Traffic Filter" condition, select "bulk carrier" in the ship type, "anchoring" in the state, draught" above 10 meters ", and ship deadweight DWT" 100k and above "in order to screen out the ships carrying iron ore in the port anchorage, which can be clearly and intuitively displayed on the map.

The following figure takes Lianyungang Port as an example,

If you have doubts about a ship at the anchorage or want to know more about the cargo situation, you can query the loading port of the ship for that voyage through the ship's historical trajectory.
