Description

Technical Field

[0001] The present invention relates to the technical field of ship fuel tanks, and in particular to a fuel tank support structure and a ship comprising the same. Background Art

[0002] Faced with the fiercely competitive ship market and increasingly stringent emission requirements, dual-fuel ships are one of the development directions of clean and low-carbon ship technology, among which methanol fuel is rapidly developing into the preferred alternative clean fuel for ships by many shipping companies. Compared with LNG, methanol is easier to store, transport and handle, and its energy density is also higher than other alternative clean fuel marine fuels.

[0003] The mainstream solution on the market is to place the methanol fuel tank on the main deck of the cargo hold area, but the existing fuel tank layout does not have sufficient structural strength and may affect the equipment layout on the main deck due to the space occupied. Since pipeline equipment and brackets need to be placed above the main deck, and safe passage space needs to be reserved, the existing fuel tank structure cannot take into account both structural strength and saving of deck surface space layout, and is not convenient for people on the deck to pass through. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of weak strength and large occupation area of ​​the fuel tank support structure of the ship in the prior art, and to provide a fuel tank support structure and a ship comprising the same.

The transverse and longitudinal brackets support each other, so that a better structural strength can be obtained in a smaller footprint; and by providing vertical reinforcing ribs on the inner surface of the bracket and brackets on the outer surface, local stress concentration is reduced, the stability of the overall structure is improved, and a high-strength support structure can be formed in a limited layout space, thereby reducing the footprint. At the same time, the fuel tank support structure is arranged on at least one side of the main deck, leaving space for other arrangements on the deck, such as pipelines, safety passages, etc.

[0011] Preferably, the first hole is spaced apart from the longitudinal boundary support.

[0012] In this solution, the first hole is spaced apart from the longitudinal boundary support so that the first hole is positioned at an appropriate distance from the boundary support, thereby ensuring the structural strength of the longitudinal boundary support as the main load-bearing support structure.
