Abstract
Description
The present invention relates to a support structure for horizontally extended LNG storage tank, by removing the support skirt and supporting the entire horizontally extended LNG storage tank to the hull through the support block to remove the stress concentration phenomenon applied to the connection portion of the horizontal extension tank portion The horizontal extension LNG storage tank support structure for preventing the rotation of the horizontal extension LNG storage tank by installing a rotation prevention support on the side of the first and second tank.
In general, older LNG storage tanks mounted on LNG carriers should be designed to allow the loading of more LNG within a range that does not interfere with the ship's view.
The LNG storage tank is configured by connecting two hemispherical tanks and expands to install a cylindrical extension between the two hemispherical tanks so that the LNG storage capacity can be increased. It is divided into an extended LNG storage tank and a horizontal extended LNG storage tank.
Conventional horizontally extending
The horizontal extension
An object of the present invention for solving the above problems is to remove the support skirt by supporting the entire horizontally extended LNG storage tank through the support block, to reduce the stress concentration phenomenon applied to the connection portion of the horizontal extension tank portion It also provides a horizontally extended LNG storage tank support structure for securing the horizontally extended LNG storage tank by fixing to the hull with a rotation prevention support on the side.
The present invention to achieve the object as described above and to solve the conventional drawbacks, the first and second tank parts symmetrical to each other and formed in a hemispherical shape; A horizontally extended LNG storage tank comprising a horizontally extending tank portion installed between the first and second tank portions to increase the LNG storage capacity; A base portion formed concavely on the hull so that the horizontally extended LNG storage tank can be installed; A support block installed between the horizontally extending LNG storage tank and the base part to support the horizontally extending LNG storage tank; And an anti-rotation support formed at the side center of the first and second tanks to be fixed to the base to prevent rotation of the horizontally extended LNG storage tank.
As described above, according to the present invention, the stress concentration phenomenon occurs in the connection portion of the horizontal extension tank and the first and second tanks by removing the support skirt and supporting the support block in supporting the horizontal extension LNG storage tank. It is a very useful invention to reduce the thickness of the horizontal extension tank to reduce the production cost by reducing the material cost, and to be securely supported and fixed inside the installation through the anti-rotation support.

Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

According to the present invention, the
According to the present invention, as shown in the drawing, the
As the stress concentration is alleviated, the thickness of the
Meanwhile, the
The reason why the first support block and the second support block are divided into the first support block is a hollow steel structure, and the second support block is a solid wood or a structure having similar elasticity. The first support block may also be replaced with the same material as the second support block, but because the inside of the material needs to be filled up, it may be expensive.
Meanwhile, the
In addition, the
On the other hand, since the
As the structure supporting the horizontal storage LNG storage tank through the support skirt as in the prior art, not only the stress of the tank portion, but also the stress of the support skirt portion is significantly increased, so that the tank and the support skirt of excessive thickness must be manufactured, resulting in very low productivity and a significant increase in cost. There is a very difficult problem to apply.
The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
