Abstract

A platform for a semi-submersible floating type offshore structure according to an exemplary embodiment of the present invention includes a main body which is installed on the sea and has an arrangement structure in which a plurality of pontoons is combined to form a plurality of polygonal shapes; and a protrusion member connecting unit which extends from each corner of the main body and connects a protrusion member outwardly protruding from the main body to the main body.

First claim

The invention claimed is:

1. A platform for a floating type offshore structure comprising:
a main body which is installed on the sea and has an arrangement structure in which a plurality of pontoons are combined to form a plurality of polygonal shapes;
a protrusion member on which a tower is installed; and
a protrusion member connecting unit which extends from each corner of the main body and connects the protrusion member to the main body,
wherein the protrusion member protrudes outwardly from the main body and is located at an end of the protrusion member connecting unit,
wherein the protrusion member connecting unit is formed to outwardly protrude with respect to a center of the main body and an extending length direction of the protrusion member connecting unit intersects the center of the main body,
wherein mooring line fastening units connecting a mooring line are installed at a side pontoon of the main body,
wherein the mooring line fastening units are installed on both sides of the corner, and
wherein the mooring line fastening units are disposed to be symmetrical to each other with respect to the extending length direction of the protrusion member connecting unit.

2. The platform for the floating type offshore structure of claim 1 , wherein the tower is a wind tower for wind power generation.

3. The platform for the floating type offshore structure of claim 1 , wherein the main body includes an upper horizontal connecting unit and a lower horizontal connecting unit which have an arrangement structure in which the plurality of pontoons are coupled in a horizontal direction and spaced apart from each other to be parallel; and a vertical connecting unit which is disposed between the upper horizontal connecting unit and the lower horizontal connecting unit to be perpendicular thereto.

4. The platform for the floating type offshore structure of claim 3 , further comprising:
a protrusion member reinforcing unit which connects the side pontoon of the main body and the protrusion member and extends from the vertical connecting unit of the main body to be inclined.

5. The platform for the floating type offshore structure of claim 4 , wherein the protrusion member reinforcing unit is formed to be downwardly inclined from an upper portion of the vertical connecting unit of the main body.

6. The platform for the floating type offshore structure of claim 4 , wherein the protrusion member reinforcing unit is formed to be upwardly inclined from a lower portion of the vertical connecting unit of the main body.

7. The platform for the floating type offshore structure of claim 4 , wherein the protrusion member reinforcing unit includes a first protrusion member reinforcing unit which is formed to be downwardly inclined from the upper portion of the vertical connecting unit of the main body; and a second protrusion member reinforcing unit which is formed to be upwardly inclined from the lower portion of the vertical connecting unit of the main body.

8. A semi-submersible offshore structure comprising a platform for a floating type offshore structure having a protrusion member comprising:
a main body which is installed on the sea and has an arrangement structure in which a plurality of pontoons is combined to form a plurality of polygonal shapes;
a protrusion member on which a tower is installed; and
a protrusion member connecting unit which extends from each corner of the main body and connects the protrusion member to the main body,
wherein the protrusion member protrudes outwardly from the main body and is located at an end of the protrusion member connecting unit,
wherein the protrusion member connecting unit is formed to outwardly protrude with respect to a center of the main body and an extending length direction of the protrusion member connecting unit intersects the center of the main body,
wherein a mooring line fastening unit for connecting a mooring line is installed at a side pontoon of the main body,
wherein the mooring line fastening units are installed on both sides of the corner, and
wherein the mooring line fastening units are disposed to be symmetrical to each other with respect to the extending length direction of the protrusion member connecting unit.

9. The semi-submersible offshore structure of claim 8 , wherein the tower is a wind tower for wind power generation.

10. The semi-submersible offshore structure of claim 8 comprising the platform for a floating type offshore structure having the protrusion member wherein the main body includes an upper horizontal connecting unit and a lower horizontal connecting unit which have an arrangement structure in which the plurality of pontoons is coupled in a horizontal direction and spaced apart from each other to be parallel; and a vertical connecting unit which is disposed between the upper horizontal connecting unit and the lower horizontal connecting unit to be perpendicular thereto.

11. The semi-submersible offshore structure of claim 8 further comprising:
a protrusion member reinforcing unit which connects the side pontoon of the main body and the protrusion member and extends from the vertical connecting unit of the main body to be inclined.

12. The platform for the semi-submersible offshore structure of claim 8 , wherein the protrusion member reinforcing unit is formed to be downwardly inclined from an upper portion of the vertical connecting unit of the main body.

13. The platform for the semi-submersible offshore structure of claim 8 , wherein the protrusion member reinforcing unit is formed to be upwardly inclined from a lower portion of the vertical connecting unit of the main body.

14. The platform for the semi-submersible offshore structure of claim 8 , wherein the protrusion member reinforcing unit includes a first protrusion member reinforcing unit which is formed to be downwardly inclined from the upper portion of the vertical connecting unit of the main body; and a second protrusion member reinforcing unit which is formed to be upwardly inclined from the lower portion of the vertical connecting unit of the main body.

15. A platform for a floating type offshore structure, comprising:
a main body which is installed on the sea and has an arrangement structure in which a plurality of pontoons is combined to form a plurality of polygonal shapes;
a protrusion member on which a tower is installed;
a protrusion member connecting unit which extends from each corner of the main body and connects the protrusion member to the main body,
wherein the protrusion member protrudes outwardly from the main body and is located at an end of the protrusion member connecting unit, and
wherein the main body includes an upper horizontal connecting unit and a lower horizontal connecting unit which have an arrangement structure in which the plurality of pontoons is coupled in a horizontal direction and spaced apart from each other to be parallel, and a vertical connecting unit which is disposed between the upper horizontal connecting unit and the lower horizontal connecting unit to be perpendicular thereto; and
a protrusion member reinforcing unit which connects a side pontoon of the main body and the protrusion member and extends from the vertical connecting unit of the main body to be inclined,
wherein the protrusion member reinforcing unit is formed to be downwardly inclined from an upper portion of the vertical connecting unit of the main body.
