Cage engineering ship and ship-borne cage construction method

Abstract

The invention discloses a cage engineering ship and a ship-borne cage construction method. The cage engineering ship comprises a ship body, and a cage floating pipe framework construction device is mounted in a floating pipe framework construction launching area of a deck of the ship body. The cage floating pipe framework construction device is provided with a hot melting welder, a winch, four guide rollers, a first limiting column and a second limiting column at relatively fixed positions. A first steel wire rope and a second steel wire rope are wound sequentially through the winch, and buttwelding is completed by the hot melting welder, so that cage floating pipe framework construction is realized. By the cage engineering ship, raw materials can be transported to a cage mounting sea area, then cage floating pipe framework construction is completed on the ship, and launching is performed, so that problems of difficulty in searching of a site suitable for cage floating pipe frameworkconstruction and difficulty in launching in the prior art are solved. In addition, the automation degree of cage floating pipe framework construction is raised, manpower resources required for cage floating pipe framework construction are reduced, and cage floating pipe framework construction quality is guaranteed.

Description

technical field [0001] The invention relates to a net cage engineering ship and a construction method of a ship-mounted net cage. Background technique [0002] The development of deep-water cage industry is a national policy, and the engineering link of deep-water cages is a short board that restricts the development of the industry. In recent years, my country's cage aquaculture industry has developed rapidly. The total number of cages has exceeded 1.1 million, but most of them are traditional wooden fish rafts. HDPE deep-water anti-wind and wave cages are only more than 12,000, less than 1%. With the continuous occurrence of natural disasters that damaged traditional wooden fish rafts, and the excellent performance of HDPE deep-water anti-storm net cages in resisting natural disasters, HDPE deep-water anti-wind and wave net cages have been more and more recognized by the farming grassroots. The department also encourages the development of HDPE deep-water anti-wind and wa...

Problems solved by technology

In recent years, my country's cage aquaculture industry has developed rapidly. The total number of cages has exceeded 1.1 million, but most of them are traditional wooden fish rafts. HDPE deep-water anti-wind and wave cages are only more than 12,000, less than 1%.

Land transportation requires the loading and unloading of raw materials. As the pipe specifications become larger and the labor costs become higher, external loading and unloading machinery is often unavoidable; the situation of both land and water transportation is more complicated. In addition to the need to coordinate external For loading and unloading machinery, it is also necessary to hire external transport ships, taking into account the functions and dimensions of the ships, the berthing conditions of the docks, and the respective arrival time. A slight difference in coordination may result in double ship rental fees, double hoisting fees, dock occupancy fees or additional land transportation costs, and multiple transfers may cause scratches on the surface of raw materials, which will bring hidden dangers to the quality of subsequent cage construction and use safety

Therefore, in the transportation of raw materials to the site, not only the economic cost of transportation is high, but also various coordination is time-consuming and laborious, and the cost of communication and coordination is high.

[0007] 2. Current status of the construction site

[0013] Due to the above shortcomings, the on-site management is extremely chaotic, and the situation of safety and labor protection is also very severe.

Due to the limitation of the construction site, the primitive and crude operation tools, and the lack of standardization and low technical content of various operations, whether it is land construction or offshore construction, the construction site is often chaotic and has no formal management. model and the most basic safety production requirements at all

Items are placed in a mess, tools and construction materials are mixed randomly, electrical equipment wires and cables are not protected, and high-temperature and high-heat equipment are not protected
