Preferably, the air permeable mast is disposed above the wing bridge.

In the technical scheme, the ventilating mast is arranged above the bridge wing, so that the supporting of the ventilating mast is facilitated, and the control on a dangerous area formed by the liquid tank is facilitated.

Preferably, the horizontal field of view of the said bridge wing extends to a sector of not less than 225 degrees.

In the technical scheme, the horizontal vision field of the bridge wing is at least 45 degrees from the bow of the dual-fuel bulk carrier to the front, and then from the front to the front of the dual-fuel bulk carrier to the front tail of the same side of the dual-fuel bulk carrier through 180 degrees, so that the vision field range is wider, and the safety requirement of the vision field in the sailing process is met.

Preferably, the hoisting mechanism is arranged along the side surface of the liquid tank in the length direction.

Among this technical scheme, hoisting machine constructs along fluid reservoir length direction's side setting for hoisting machine constructs to form effectual side physical protection to the fluid reservoir.

Preferably, the number of the liquid tanks is two, the two liquid tanks are arranged in parallel, and the length directions of the two liquid tanks are the same as the length direction of the dual-fuel bulk cargo ship.

In this technical scheme, the length direction of fluid reservoir is the same with the extending direction of dual fuel bulk cargo ship for boats and ships and fluid reservoir atress are even, and when the sea water impacted ship side, the angle of fluid reservoir was difficult to the skew.

Preferably, the hoisting mechanism is arranged on one side of the liquid tank close to the ship board.

Among this technical scheme, hoisting machine constructs to be established in the fluid reservoir and is close to one side of ship board for the fluid reservoir is located hoisting machine constructs's inboard, is convenient for remove and hangs the fluid reservoir of getting.

The positive progress effects of the invention are as follows:

the separately arranged bridge wing support, the guide rail support of the hoisting mechanism and the air-permeable mast support of the liquid tank are combined, so that the separate structural supports required by the hoisting mechanism, the air-permeable mast and the like are saved, the number of structural components of the support structure is reduced, and the structural weight is reduced.

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

As shown in figures 1 and 3, the invention discloses a dual-fuel bulk cargo ship, which comprises a deck 1, a tank 2, a bridge wing 6 and a hoisting mechanism 4. The liquid tank 2, the bridge wing 6 and the hoisting mechanism 4 are all arranged on the deck 1. The tank 2 includes a gas permeable mast 3, the gas permeable mast 3 being part of a pressure relief system for the tank 2 to relieve pressure from the tank 2. The bridge fin 6 is arranged above the tank 2. The hoisting mechanism 4 can adopt a monorail crane, the monorail crane is opposite to the cantilever crane, special arrangement is not needed according to the physical protection working radius of the liquid tank 2, the design is simple, and the structure is convenient. The hoisting mechanism 4 comprises a guide rail support 5, and the bridge wing 6 and the ventilating mast 3 are both arranged on the guide rail support 5.

The original separately arranged bridge wing 6 support, the guide rail support 5 of the monorail crane and the air-permeable mast 3 of the liquid tank 2 emergency release system are properly combined, so that the guide rail support 5 of the monorail crane and the independent structural support of the air-permeable mast 3 are saved. The structure supported by the bridge wings 6 is reinforced, so that the vibration of the bridge wings 6 is improved, the number of structural components for supporting can be reduced on the whole, and the structural weight is reduced.

As shown in fig. 1 and 3, the air permeable mast 3 of the tank 2 can extend above the bridge wing 6 by structural support of the bridge wing 6, which facilitates support of the air permeable mast 3 and also control of hazardous areas.

As shown in fig. 1 and 3, the dual fuel bulk carrier includes a living cabin provided on a deck 1, a bridgewall 6 provided behind the living cabin, and both sides of the bridgewall 6 extending to the widest position of the deck 1. The view of the observation position and the operation position of the dual-fuel bulk cargo ship is wider. The horizontal visual field of the bridge wing 6 extends to a sector not less than 225 degrees, the horizontal visual field of the bridge wing 6 extends from the bow of the dual-fuel bulk carrier to at least 45 degrees through the straight front, and then from the straight front to 180 degrees through the straight tail of the same side of the dual-fuel bulk carrier, so that the visual field range is wider, and the safety requirement of the visual field in the sailing process is met. If the vision range does not meet the requirements, further beveling can be adopted for the front cabin of the cockpit of the bridge wing 6 to meet the specification requirements.

As shown in fig. 2 and 3, the hoisting mechanism is arranged along the side surface of the liquid tank 2 in the length direction, so that the hoisting mechanism 4 forms effective side surface physical protection for the liquid tank 2, the hoisting mechanism 4 is arranged on one side of the liquid tank 2 close to a ship board, so that the liquid tank 2 is positioned on the inner side of the hoisting mechanism 4, and the liquid tank 2 is convenient to move and hoist. The two liquid tanks 2 on the dual-fuel bulk cargo ship are arranged in parallel, and the length directions of the two liquid tanks 2 are the same as that of the dual-fuel bulk cargo ship.
