Technical Field

The invention relates to a method for arranging a lower platform of an oil tank in a ship cabin area.

Background

At present, a fuel oil daily cabin, a fuel oil clarification cabin and the like are usually arranged in a ship cabin area and are used for daily fuel oil consumption. In order to ensure that fuel can be fully utilized, the bottom of the oil tank is provided with an inclined bottom, and in order to prevent the oil tank from being damaged and polluting the engine room, the lower part of the second plate is provided with an isolated empty tank. Because the inclined bottom is close to the second plate, the height of the isolated empty cabin is not high, and on the premise of ensuring the structural strength, no effective method exists at present how to solve the construction problem at the position.

Disclosure of Invention

The invention aims to provide a method for arranging a platform at the lower part of an oil tank in a ship engine room area, which optimizes the structural design, lightens the structural weight and facilitates field construction on the premise of ensuring the structural strength.

The technical scheme for realizing the purpose is as follows:

a method for arranging a lower oil tank platform in a ship cabin area comprises the following steps:

determining the position of a large opening of a second deck according to a layout of a cabin;

secondly, holes are formed in a second deck of the cabin;

thirdly, structurally arranging an inclined plate at the bottom of the oil tank;

and step four, carrying out structural arrangement on the bottom plate of the isolated empty cabin according to the step three.

Preferably, the nacelle layout comprises: fuel compartment layout and compartment layout.

Preferably, in the second step, the bulkhead, the frame and the longitudinal bone around each oil tank are respectively offset 100mm medially, and then the holes are generated by chamfering R200 mm.

Preferably, in the third step, with reference to the cabin structure diagram, the inclined plate at the bottom of the oil cabin is structurally designed according to a longitudinal skeleton, the longitudinal skeleton ends at the cabin walls of the two side cabins, the elbow plates are arranged at the ends, and the middle part is continuous.

The invention has the beneficial effects that: according to the invention, by arranging the platform at the lower part of the oil tank, the structural design is optimized on the premise of ensuring the structural strength, and the large holes are formed in the second plate, so that the structural weight is reduced. The construction space becomes big, makes things convenient for site operation. The welding workload is reduced. The construction process is simple, the production efficiency is improved, and the inspection reporting work of the ship inspection in the later period is facilitated. The oil tank is particularly suitable for the condition that the lower part of the oil tank of the ship is provided with an inclined bottom and an isolated empty tank.

Detailed Description

The invention will be further explained with reference to the drawings.

Referring to fig. 1 to 8, the method for arranging the lower platform of the oil tank in the ship cabin area of the present invention includes the following steps:

step one, determining the position of the large opening of the second deck according to a layout of the engine room. The nacelle layout includes: fuel compartment layout and compartment layout. In the figure, FR27, FR31 and FR34 are strong frameworks, and the structural design is shown in figure 7. FR23 and FR37 are cabin bulkheads, and the structural design is shown in figure 8. The third gear between FR23 and FR27 is a common frame, and the structural design is shown in FIG. 6.

Step two, generating holes on a deck of the second cabin: the bulkhead, frame and longitudinal bars all around each tank are each offset 100mm medially and then chamfered R200mm to create holes. Taking the fuel day tank as an example, FR23, FR27, longitudinal ribs and isolated empty tank walls are each displaced 100mm medially, and then chamfered R200mm to create hole 1. By analogy, holes 2,3,4 are produced in the second deck of the nacelle.

And step three, referring to a cabin structure diagram, structurally designing the inclined plates at the bottom of the oil cabin according to a longitudinal skeleton type, wherein longitudinal ribs are terminated at cabin walls of the cabins at two sides, toggle plates are arranged at the terminated positions, and the middle of the longitudinal ribs is continuous. As shown in fig. 4.

Step four, the structural arrangement is carried out on the bottom plate of the isolation empty cabin according to the step three, and the structural arrangement is shown in figure 5.

In conclusion, the invention reduces the structure weight, is convenient for field construction and improves the production efficiency.

The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
