A marine structure platform is comprised of: horizontal connecting parts which are connected to one another in a lattice structure; vertical connecting parts which are installed uprightly at four corners of the horizontal connecting parts and in use protrude 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, the movement damping parts with a plate shape so as to define a vertical gap therebetween, wherein the movement damping part includes a pair of movement damping plates (311, 312) which defines the gap and is opened along an interior of the horizontal connecting parts, the marine structure platform is characterized by, wherein one or more vertical reinforcing members are installed in a space between the pair of movement damping plates (311, 312) so as to connect and support the pair of movement damping plates (311, 312), wherein a radial reinforcing member is formed to be radially extended from the circumference of the vertical reinforcing member on at least one of the pair of movement damping plates (311, 312), wherein a vortex inducing hole is formed in the pair of movement damping plates (311, 312) so as to vertically penetrate the pair of movement damping plates (311, 312), and the vortex inducing hole is formed to expose a part of the vertical connecting part, 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, the radial reinforcing member is formed along an inner surface of the movement damping plate so as to connect a circumference of the vertical reinforcing member and a circumference of the movement damping plate. horizontal connecting parts which are connected to one another in a lattice structure; vertical connecting parts which are installed uprightly at four corners of the horizontal connecting parts and in use protrude 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, the movement damping parts with a plate shape so as to define a vertical gap therebetween, wherein the movement damping part includes a pair of movement damping plates (311, 312) which defines the gap and is opened along an interior of the horizontal connecting parts, the marine structure platform is characterized by, wherein one or more vertical reinforcing members are installed in a space between the pair of movement damping plates (311, 312) so as to connect and support the pair of movement damping plates (311, 312), wherein a radial reinforcing member is formed to be radially extended from the circumference of the vertical reinforcing member on at least one of the pair of movement damping plates (311, 312), wherein a vortex inducing hole is formed in the pair of movement damping plates (311, 312) so as to vertically penetrate the pair of movement damping plates (311, 312), and the vortex inducing hole is formed to expose a part of the vertical connecting part, 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, the radial reinforcing member is formed along an inner surface of the movement damping plate so as to connect a circumference of the vertical reinforcing member and a circumference of the movement damping plate.
