Information
How much do you know about shipping? If you want to know, just follow the editor of Hong Kong ocean freight forwarder to have a simple understanding!
1. Port waters
The area of water within the port boundary. It generally has to meet two basic requirements: that is, ships can safely enter and leave the port and dock and leave the dock; and can stably carry out berthing and loading and unloading operations. The port waters mainly include the waters in front of the pier, the waterway in and out of the port, the waters where the ship turns around, the anchorage, and the navigation aid signs.
2. Approach to the port
The passage for ships to enter and exit the waters of the port area and connect with the main channel. It is generally set in waters where the natural water depth is good, the amount of back siltation is small, and crosswinds and crosswinds are avoided as much as possible. The arrangement direction should be straight along the flow of water. According to the frequency of navigation of ships, one-way or two-way channels can be used respectively. When the navigation density is relatively small, in order to reduce the amount of excavation and the amount of silt back siltation, after technical and economic comparison and full research, a one-way channel can be considered. The width of the channel is generally determined by factors such as speed, horizontal position of the ship, possible lateral drift, etc., plus the necessary surplus width. The water depth of the entry channel is generally considered based on the principle of large ships entering and leaving the port by tide under the conditions of large engineering volume and difficulty in remediation; The principle of entry and exit is determined. The water depth of the approach channel of the river port should ensure the safe passage of the design standard ship type.
The above is the introduction of Hong Kong ocean freight forwarder editor: maritime related knowledge.
