Description
Technical Field
The invention relates to the technical field of ships, in particular to a methanol fuel tank arrangement structure of a container ship.
Background
Methanol fuel is used as a novel clean fuel and is more and more widely applied to ships.
According to international safety regulations for ships using gas or other low flash point fuels (IGF regulations), methanol fuel tanks can take the form of both integral and free-standing tanks. The independent liquid cargo hold needs to be additionally provided with the supporting cushion block, so that the space utilization rate is not high. Because the methanol temperature is much higher than that of Liquefied Natural Gas (LNG), the methanol fuel tank has great advantages by adopting an integral tank.
The integral methanol fuel tank is mainly applied to small container ships at present. With the increase in size of ships, more and more fuel is required. Because the liquid cabin is too wide in the transverse direction and the free liquid level is too large, the original one cabin needs to be divided into a left fuel cabin and a right fuel cabin. The provision of the intermediate bulkhead makes the task of painting and degassing the methanol fuel tank difficult.
At present, a methanol fuel tank arranged in a ship cabin is mainly a small-sized tank, and the aim of smoothing the inner walls around the fuel tank is easily realized in structure. For a large container ship with a double-island design, in order to save space, the methanol fuel tank is arranged in a lower cargo hold area of a living building where containers are not suitable to be placed, with reference to the arrangement of the film type LNG fuel tank. Compared with the difficulty that the middle bulkhead cannot be arranged on the film type LNG fuel, the methanol fuel tank can solve the problems that the free liquid level is too large and the like by arranging the middle bulkhead. The patent with the publication number of CN204507165U discloses a methanol tank structure of a ship, which comprises a left methanol tank and a right methanol tank, wherein a tank wall between the left methanol tank and the right methanol tank is of an arch structure. The methanol cabin structure has the defect of difficult construction.
The existing integral large methanol fuel tank is less in application, and in order to solve the problems of overlarge free liquid level and the like, the arrangement of dividing one large methanol fuel tank into a left small methanol tank and a right small methanol tank can cause the addition of a middle tank wall and various structures on the middle tank wall, so that special coating and degassing in the fuel tank become difficult.
