Description

Passenger roller boat

Technical Field

The invention belongs to the technical field of ship preparation, and particularly relates to a ro-ro passenger ship.

Background

In marine design, liquefied Natural Gas (LNG), which is widely used as a clean energy source, is stored in an LNG tank. According to the specification, the LNG tanks on the ship are generally arranged in pairs and are bilaterally symmetrical on both sides of the center line of the ship body. The LNG tank is huge in volume, occupies a large amount of cabin space, and needs to be provided with a special LNG cabin. In the prior art, a saddle is usually adopted for fixing at the bottom, and then an LNG tank is fixed on an LNG cabin surrounding wall through a bracket. Referring to fig. 1, the provision of a longitudinal bulkhead 101 between two LNG tanks 10 within the LNG compartment 102 alone is not significant to the overall hull longitudinal strength. Moreover, the space inside the LNG tank 102 is limited, and the longitudinal walls occupy a large amount of space, increase the steel consumption, increase the shipbuilding cost, and affect the arrangement of the LNG tank and the maintenance space.

In order to realize better floating stopping effect, the patent publication No. CN207466901 discloses a floating stopping structure of an LNG fuel cabin of an automobile ro-ro ship, which comprises a deck and a tank cabin, wherein the tank cabin is arranged on the lower surface of the deck, the tank cabin comprises a left longitudinal bulkhead, a right longitudinal bulkhead and an inner bottom plate, and further comprises a first floating stopping mechanism, two second floating stopping mechanisms and two saddles, the two saddles are fixed on the upper surface of the inner bottom plate at intervals, the upper surfaces of the saddles are provided with grooves sunken downwards, and LNG fuel tanks are placed in the grooves. Effectively prevent the come-up after the LNG fuel jar is damaged, simultaneously, the deck of jar cabin top can not directly receive the ascending buoyancy of LNG fuel jar and assault, and just receive from the left and right less buoyancy that ends that indulges bulkhead transmission and come, its deformation that has effectively reduced the deck has improved the security performance. In the scheme, however, on one hand, the floating stop block and the floating stop cover are not rigidly connected, so that the fixing effect is poor; on the other hand, the span of the upper deck beam is large, more steel needs to be used, the using amount of the steel cannot be reduced, the shipbuilding cost cannot be well reduced, and good economic benefits cannot be achieved.
