As fishery ships gradually come into CCS inspection and the nations increasingly pay attention to ship safety and ocean pollution, the frequency of dock-loading maintenance of fishery ships is greatly increased. However, the docking time of the fishery ship is centralized, the repair price of a single ship dock is low, and the traditional ship repair enterprises are not willing to carry out fishing ship maintenance. If the ship is accepted by other enterprises, the investment of a dry dock and a sliding slipway for docking ships is large, the occupied area is wide, and the economic benefit is poor due to the use characteristics of fishery ships.

A dock is a dock-type building for repairing ship, which can be used for filling water and making ship pass in and out, and can be used for repairing ship on dry bottom after water is drained. Docks can be classified into dry docks, water-filled docks and floating docks.

Draft (Draught) generally refers to the depth to which a ship is submerged in water. Which is the vertical distance from the bottom of the vessel to the point where the hull is connected to the water surface, indirectly reflects the buoyancy to which the vessel is subjected during travel (or the weight of the hull and its cargo, etc., as this is equivalent to the buoyancy to which the hull is subjected).

PE refers to Polyethylene (PE) which is a thermoplastic resin obtained by polymerizing ethylene. In industry, copolymers of ethylene with small amounts of alpha-olefins are also included. The polyethylene is odorless and nontoxic, feels like wax, has excellent low-temperature resistance (the lowest use temperature can reach-100 to-70 ℃), has good chemical stability, and can resist corrosion of most of acid and alkali (cannot resist acid with oxidation property).
