Description

Gravity Type Structure {GRAVITY BASED STRUCTURE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravity type structure, and more particularly, to a gravity type structure that is modularized and light in weight and easy to arrange.

Gravity Based Structure (GBS) is usually installed near the coast and can land on the seabed by its own weight.

These gravity structures can be used to store oil or gas or to unload stored oil or gas.

Generally, gravity structures are usually formed of concrete and reinforcing bars. In addition, a stiffener or the like may be further provided so as not to be damaged in the process of moving to the installation area.

Therefore, it is difficult to move to the installation area due to its large size and heavy weight, and a large installation space may also be required.

1 and 2, a gravity type structure is generally landed on a seabed 70 by its own weight and is formed of a plurality of structures 60 installed in a housing part 50 and a housing part 50 .

The housing part 50 may be provided with a storage tank for storing fuel, and the structure 60 may be a facility room including facilities. Although the storage tanks or facility rooms may have different sizes, the housing part 50 may be formed in one large accommodation space rather than according to the shape of the structure 60 for convenience of manufacturing.

The large receiving space of the housing part 50 can accommodate a weight such as sand or ballast water. This is for increasing the load of the housing part 50, and the load of the housing part 50 may be a load of a magnitude that the gravity type structure can resist the wave force.

Therefore, as shown in FIG. 2, the housing part 50 may be formed with an empty space in which the structures 60 are not disposed. In addition, such unnecessary empty space can increase the weight of the gravity type structure.

Accordingly, a gravity type structure that can reduce the unnecessary empty space of the gravity type structure and easily move to the installation area may be required.
