Problems solved by technology

[0004] Since the size of some super-large structures or ship-shaped cargo exceeds the loading and unloading capacity of semi-submersible ships, this puts forward higher requirements for the carrying capacity, space size, weight range and reserve buoyancy of semi-submersible ships. Traditional semi-submersible ships use pontoons Difficult to meet higher demands

Abstract

The invention relates to a method for transforming buoyancy tanks of semi-submersible ships. The method for transforming the buoyancy tanks of the semi-submersible ships includes longitudinally or transversely cutting the original buoyancy tanks of the ships to form first buoyancy tanks and second buoyancy tanks; carrying out outer plate welding on cut surfaces of the first buoyancy tanks and thesecond buoyancy tanks and guaranteeing that the first buoyancy tanks and the buoyancy tanks are still of water-tight pressure-proof tank structures; additionally arranging first top buoyancy tanks andfirst bottom buoyancy tanks at the tops and the bottoms of the first buoyancy tanks; additionally arranging second top buoyancy tanks and second bottom buoyancy tanks at the tops and the bottoms of the second buoyancy tanks; rearranging the first buoyancy tanks and the second buoyancy tanks on decks. The method for transforming the buoyancy tanks of the semi-submersible ships has the advantages that the semi-submersible ships can be stable and reliable, and large goods loading and transporting requirements can be met.

Description

technical field [0001] The invention relates to a method for improving a floating tank of a hull, in particular to a method for improving a floating tank of a semi-submersible ship. Background technique [0002] A semi-submersible ship is a marine engineering ship used for the transportation of large structures at sea. The basic external features of a semi-submersible ship consist of the main hull, the buoyant body where the superstructure is located (usually a towering forecastle or poop) and a buoyancy box (usually a stern buoyancy box). [0003] The diving condition requires that the semi-submersible ship has sufficient stability, safety and reliability. The stern pontoon or bow pontoon must be able to provide sufficient moment of inertia on the water plane surface to provide an initial stability height value that meets the specifications or use requirements for the dive. The design of the box is critical. In order to meet the needs of loading and unloading large-scale ...
