How much do you know about engineering vessels?
Engineering vessels refer to ships that specialize in certain types of water or underwater projects. They are mainly divided into four categories: dredgers, floating crane, salvage ships, and floating docks.
- Dredger
The dredger is a ship that digs, lifts and transports sediments such as soil, sand, rocks and coral reefs from the underwater surface layer. According to different construction characteristics, it can be subdivided into cutter suction dredgers, trailing suction dredgers, grab dredgers, etc.
- Floating Crane
Floating crane, also known as crane barge, refers to engineering vessels equipped with lifting equipment for the construction of harbors, hydraulic buildings, underwater salvage and harbor loading and unloading, etc., lifting and moving heavy loads on water.
- Salvage ships
The salvage ship is the engineering vessel used for rescuing ships in distress on the water and salvaging wrecks. The main working machinery it is equipped with include cranes, winches and air compressors, as well as underwater welding, cutting, repairing, drainage, floating and other salvage equipment.
- Floating Dock
The floating dock is the engineering vessel that can sink and float and move in a certain water area, which is used to lift the ships for repair or transfer to shallow water areas.
It can undertake the repair projects of 10,000-ton oil tankers, bulk carriers, large full container ships and other large offshore engineering structures. It can also be used for the docking, reconstruction and manufacturing of large ships and ocean engineering.
