In order to reduce the influence of the free liquid on the stability, the transverse dimensions are smaller and are symmetrically arranged with respect to the longitudinal center line of the ship.
For deep V-shaped ship bodies below 40 meters, when the fuel oil storage cabin is in a deep V-shaped structure line type, the arrangement of the main engine and the generator set is higher than that of the fuel oil cabin due to the limitation of the structure, and the pump of the main engine and the generator set is separated from the deep V-shaped oil cabin by a certain height difference. The height difference is larger than the suction height of the belt pump, so that the belt pump cannot pump fuel exceeding the suction height area at the bottom of the fuel storage cabin, and cannot pump the fuel and cannot be used. Therefore, in the existing ship fuel supply system, a fuel daily cabinet is designed, the fuel in the fuel storage cabin is automatically conveyed into a daily fuel tank for an engine through a delivery pump and a pipeline, and the fuel daily cabinet is independent of the fuel storage cabin and is arranged at a higher position in the ship engine cabin, and directly supplies the fuel required by the running of the ship engine in a gravity self-flowing mode. The structural design occupies a part of the space of the ship body, and related pipelines are required to be additionally arranged, so that when more cabin equipment is arranged in the cabin area and adjacent cabin equipment, the fuel daily cabinet and the related pipelines are not arranged in space.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
As shown in fig. 1-2, when the fuel storage tank is in a deep V-structure line type for a deep V-shaped hull 1 below 40 m, the host 2 and the generator set are arranged higher than the fuel tank 3 due to the structural limitation, and the pump 4 is arranged at a certain height difference from the deep V-shaped tank. This difference in height is greater than the suction height of the belt pump 4, so that the belt pump 4 cannot pump fuel in the region beyond the suction height at the bottom of the fuel storage tank, and cannot pump the fuel, and cannot be used. Therefore, the ship cannot be used due to the fact that more oil is pumped at the bottom of the storage cabin, the number of times of filling fuel is increased, and the running cost of the ship is increased.
