The impact resistant structure which is pushed in between the tank inner wall 11 and the adjacent inner shock plate 12b is formed.

The impact resistant plate 12b formed at every corner of the oil tank has a rectangular shape with elasticity and rigidity applied thereto. A lattice-shaped groove 25 is formed on the surface of the tank inner wall 11 and the groove ( A fastening hook 21a of the tank inner wall 11 and a fastening hook 21a fastened to the fastening hook 21a of the inner shock plate 12b adjacent in one direction are formed in the inside of the tank 25, and the inner skin 3 side is formed. The fastening hook 21a which is fastened with the inner shock plate 12b adjacent in the other direction is formed in the surface.

The fastening hook 21a of the inner skin 3 side surface of the inner shock plate 12b is formed in the lattice groove 25, and when an external impact occurs, the fastening hook 21a moves along the groove 25. Since the structure is possible, the inner impact plate 12b fastened to the fastening hook 21a formed in the groove 25 is moved along the groove 25 at the time of an external impact. Therefore, the fastening hook 21b of the tank inner wall 11 and the inner shock plate 12b fastened by the fastening hook 21a and the other inner shock plate 12b do not protrude in the direction of the inner shell 3 when subjected to an external impact.

The inner shock plate 12b does not protrude in the direction of the endothelial 3 but is pushed between the inner shock plate 12b and the inner wall 11 formed in the adjacent section along the tank inner wall 11 to prevent damage to the endothelial 3.

Referring to FIG. 7, when the C2 inner impact plate 12b receives an impact applied upward from the bottom, the impact is alleviated while the A7, A8, A9, B7, B8, and B9 inner impact plates 12b are pushed up. When an impact is applied to the A5 inner impact plate 12b in the vertical direction, the impact is alleviated while A2, B3, B9, C1, C2, and C3 inner impact plate 12b are pushed and moved. When an impact is applied to the B6 inner impact plate 12b in the vertical direction, the impact shocks are alleviated while A1, A4, A7, C1, C2, and C3 inner impact plate 12b are pushed and moved. That is, when a particular inner shock plate 12b is subjected to an external impact, the plane including the inner shock plate 12b is pushed to move the shock to prevent shock and prevent the endothelial 3 from being damaged.

The oil tank has an oil inlet, an outlet, and a pressure relief port formed at an upper portion of the tank, so that the side and bottom surfaces of the tank mainly subjected to external shocks during a sea accident are not damaged by the shock absorbing structure of the endothelial structure.

In addition, the oil tank having the impact resistant structure is configured to be independent, and each of the oil tank is formed with a buoy connected to the oil lifting tube on the tank top, so that the buoy is floated during the sinking of the ship setting the position of the vessel and oil tank It is possible to remove the environmental pollution source by lifting the oil lifting tube connected to the buoy to discharge the oil inside the oil tank.

In addition, a support strap for supporting the endothelial structure is fixed to the lower surface of the upper cover fixed to the tank body by a buoyant and easily detachable fixing device, so that the fixing device is released when the ship is sunk so that the upper cover is with the endothelial structure. Floating near the surface facilitates the lifting of the endothelial structure, eliminating potential marine pollutants.

When the vessel formed with the oil storage tank according to the present invention is sunk, the leakage of oil loaded on the tank is prevented by the impact resistant structure, and the oil can be easily recovered by the buoy device, and the endothelial structure on which the oil is loaded Because of the possibility of oil being recovered near the surface, the recovery rate of oil is 99% of the total sinking, and the oil leakage to the ocean is only 1%, greatly contributing to the prevention of marine environmental pollution.
