Ship body broadside structure of semi-submersible type multifunctional transporting, disassembling and assembling ship

Abstract

The invention discloses a ship body broadside structure of a semi-submersible type multifunctional transporting, disassembling and assembling ship. The ship body broadside structure comprises a ship body shell, a main deck, a second deck, a double-layer bottom, a longitudinal bulkhead and a box type unit. The double-layer bottom is connected with the bottom of the ship body shell. The main deck isarranged at the upper part of the ship body shell; the second deck is arranged below the main deck, the longitudinal bulkhead is arranged between the double-layer bottom in the cabin and the second deck, the box type unit is connected with the top of the ship body shell, the upper portion and the lower portion of the interior of the box type unit are respectively provided with cross beams connected with the main deck and the second deck, and the left side and the right side between the two cross beams are provided with rib plate connecting supports respectively. The ship body broadside structure has the beneficial effects that the overall bearing capacity is improved, and the broadside bearing capacity is improved; and the longitudinal fender plays a role in protecting the broadside structure.

Description

technical field [0001] The invention relates to the technical field of hull structures, in particular to a hull side structure of a semi-submersible multifunctional transport and dismantling ship. Background technique [0002] The semi-submersible multi-purpose transport and dismantling ship can be used for the transportation of heavy cargo, ranging from a few hundred tons to tens of thousands of tons. It is especially suitable for offshore floating towing installation of offshore platforms, dismantling of large offshore platforms, carrying floating offshore platforms, floating docks, various hulls, offshore fishing grounds and other super-large, super-heavy and super-wide cargo. [0003] Generally, the ship's side structure mainly bears the force of the longitudinal bending, the water pressure outside the ship, the ballast water pressure in the cabin, and the impact of waves. However, for the semi-submersible multi-functional transport and dismantling ship, in the process ...

AI Technical Summary

Problems solved by technology

On the one hand, it increases the cost of the project and loses the rental income of the ship during the maintenance period. On the other hand, this type of construction requires workers to enter the closed cabin of the hull for construction. Due to the harsh internal operating environment, there are problems such as high difficulty and high risk of operation.

Because such heavy goods are often unique, temporary local reinforcements often cannot meet the needs of later projects or goods, and are also difficult to predict. Therefore, this kind of partial temporary transformation and reinforcement often occurs repeatedly, wasting resources and increasing costs.
