The present invention relates to a patriarchal structure that is moved to a crane.

Generally, natural gas is transported by the pipeline from the area where it is produced to the area where it is consumed. However, in countries where production exceeds demand, large amounts of natural gas will remain, and if there is no efficient way to transport natural gas to regions where demand exceeds supply, the energy imbalance will grow.

Liquefaction of natural gas facilitates the storage and transport of natural gas. Liquefied natural gas (LNG) is about one-sixth the volume of natural gas in the gaseous state And is made by cooling natural gas below the boiling point (-259 ° F at ambient pressure).

Therefore, all types of vessels, floats or floating structures including LNG carrier, LNG FPSO, LNG RV, etc., including LNG cargo holds are composed of, for example, an inner tank made of a metal membrane and a thermal insulation layer surrounding the inner tank, It is possible to store a LNG such as LNG that minimizes the generation of vaporized gas due to the amount of the penetration of the LNG in the cargo hold.

Such ships or floating marine structures require installation of a chieftain in the cargo hold for the cargo hold installation process.

At this time, the auxiliary structure may further include a connection frame connecting one side of the center frame and one side of the main structure, and supporting the deformation preventing member.

In this case, the deformation preventing member may be formed of a polygonal flat plate in which two adjacent sides are coupled to the center frame and the connection frame.

At this time, a rail groove into which the end of the deformation preventing member is inserted may be formed in the central frame and the connection frame.

The end of the deformation preventing member may be coupled to the center frame and the connection frame by a fastening member.

Meanwhile, a lifting auxiliary member to which the crane is connected may be provided at an upper end of the vertical tower.
