Abstract

The present invention provides a marine structure platform including: horizontal connecting parts which are disposed under the seawater and connected to one another in a lattice structure; vertical connecting parts which are installed uprightly at four corners of the horizontal connecting parts and protrude from the seawater; and movement damping parts which are extended at the four corners from the vertical connecting parts along the horizontal connecting parts adjacent to one another, the movement damping parts having a plate shape so as to define a vertical gap therebetween.

First claim

The invention claimed is:

1. A marine structure platform comprising:
horizontal connecting parts which are disposed on the sea and connected to one another in a lattice structure;
vertical connecting parts which are installed uprightly at four corners of the horizontal connecting parts and protruded from the seawater; and
movement damping parts which are extended at four corners from the vertical connecting parts along the horizontal connecting parts adjacent to one another, each of the movement damping parts having a plate shape and defining a vertical gap therebetween,
wherein the movement damping parts have a pair of movement damping plates which define the vertical gap and are opened along an interior of the horizontal connecting parts,
wherein one or more vertical reinforcing members are installed in a space between the air of movement damping plates and connect and support the pair of movement damping plates, and
wherein a radial reinforcing member is radially extended in a circumferential direction of the vertical reinforcing member on at least one of the pair of movement damping plates.

2. The marine structure platform of claim 1 , wherein outer circumferences of the pair of movement damping plates surrounded by the horizontal connecting parts are formed in a polygonal shape, a circular shape, or a fan shape.

3. The marine structure platform of claim 1 , wherein a vortex inducing hole is formed on the pair of movement damping plates and vertically penetrates the pair of movement damping plates, and the vortex inducing hole is formed to expose a part of the vertical connecting part outside.

4. The marine structure platform of claim 3 , wherein a part of an inner circumference of the vortex inducing hole surrounded by the horizontal connecting parts is formed to have a shape corresponding to a shape of an outer circumference of each of the pair of movement damping plates.

5. The marine structure platform of claim 1 , wherein the vertical reinforcing member is formed in a cylindrical shape, a circular column shape, a quadrangular container shape, a square column shape, or an I-beam shape.

6. The marine structure platform of claim 5 , wherein the radial reinforcing member is formed along an inner surface of the movement damping plates and connects a circumference of the vertical reinforcing member and a circumference of the movement damping plates.

7. A semi-submersible marine structure comprising a marine structure platform, the marine structure platform comprising:
horizontal connecting parts which are disposed on the sea and connected to one another in a lattice structure;
vertical connecting parts which are installed uprightly at four corners of the horizontal connecting parts and protruded from the seawater; and
movement damping parts which are extended at four corners from the vertical connecting parts along the horizontal connecting parts adjacent to one another, each of the movement damping parts having a plate shape and defining a vertical gap therebetween,
wherein the movement damping parts have a pair of movement damping plates which define the vertical gap and are opened along an interior of the horizontal connecting parts,
wherein one or more vertical reinforcing members are installed in a space between the pair of movement damping plates and connect and support the pair of movement damping plates, and
wherein a radial reinforcing member is radially extended in a circumferential direction of the vertical reinforcing member on at least one of the pair of movement damping plates.

8. The semi-submersible marine structure comprising the marine structure platform of claim 7 , wherein outer circumferences of the pair of movement damping plates surrounded by the horizontal connecting parts are formed in a polygonal shape, a circular shape, or a fan shape.

9. The semi-submersible marine structure comprising the marine structure platform of claim 7 , wherein a vortex inducing hole is formed on the pair of movement damping plates and vertically penetrates the pair of movement damping plates, and the vortex inducing hole is formed to expose a part of the vertical connecting part outside.

10. The semi-submersible marine structure comprising the marine structure platform of claim 9 , wherein a part of an inner circumference of the vortex inducing hole surrounded by the horizontal connecting parts is formed to have a shape corresponding to a shape of an outer circumference of each of the pair of movement damping plates.

11. The semi-submersible marine structure comprising the marine structure platform of claim 7 , wherein the vertical reinforcing member is formed in a cylindrical shape, a circular column shape, a quadrangular container shape, a square column shape, or an I-beam shape.

12. The semi-submersible marine structure comprising the marine structure platform of claim 11 , wherein the radial reinforcing member is formed along an inner surface of the movement damping plates and connects a circumference of the vertical reinforcing member and a circumference of the movement damping plates.
