Vessel type for quick lift repair of faulty ships at sea

Abstract

The invention relates to a new ship type for lifting and maintaining broken-down ships on the sea. The new ship type for lifting and maintaining broken-down ships on the sea is characterized in that the new ship type comprises a main hull of a ship-type platform, the main hull is a body combined by a floating dock structure and a semi-submersible ship structure, and the rear middle portion of the main hull is arranged in the form of the floating dock and serves as a dock repair operation area of the platform; a long forecastle in the form of the semi-submersible ship is arranged on the prow of the main hull and serves as an engine room, a living area and a command area; a fixing platform, a dock cabin and a continuous dock wall are arranged on the stern of the main hull. The new ship type for lifting and maintaining broken-down ships on the sea has the advantages that the new ship type combined by the semi-submersible ship structure and the floating dock structure is developed according to the characteristics of the two ship types; the new ship type has both the functions of the semi-submersible ship and the functions of the floating dock as well as has both the advantages of the semi-submersible ship and the advantages of the floating dock, personnel living cabins and functional cabins are arranged reasonably and completely, and the new ship type is good in stability in the descending process and the floating up process, and safe in operation; a real ship can be used after being built and is very good in effect.

Description

technical field [0001] The invention belongs to maintenance ships, in particular to a ship type for rapidly lifting and repairing marine fault ships. Background technique [0002] Among the existing types of ships, there are floating docks and semi-submersible ships that have the function of lifting or submerging ships or structures as a whole, and are widely used in ship maintenance, transportation, and launching. These two ship types have different characteristics and deficiencies. [0003] Floating docks are generally square and wireless, consisting of buoys and continuous dock walls on both sides. They have no power and are moved by tugboats. There are fewer personnel cabins and functional cabins. Due to the continuous dock walls on both sides, it has good stability and safety in the process of diving and surfacing; the semi-submersible ship is a wired type, with a long superstructure at the head, where personnel cabins and functional cabins can be arranged, and the mid...

AI Technical Summary

Problems solved by technology

During the process of diving and surfacing of semi-submersible ships, especially after the deck enters the water, the stability is poor and relatively dangerous

At present, ships that are closer to the shore can use tugboats to tow the floating dock to the faulty ship for maintenance; faulty ships in offshore navigation areas can use semi-submersible ships for maintenance, but the maintenance is very dangerous
