The present invention relates to a leg installing apparatus for fixating a ship and a leg installing method using the same and, more specifically, to a leg installing apparatus for fixating a ship and a leg installing method using the same which can easily raise a leg, stuck and fixated in the sea bed, from the sea bed to be recovered into a hull as well as stably fixate the leg in the hull. The leg installing apparatus for fixating a ship according to the present invention comprises a clamping part installed in a penetrated hole formed in the hull and pressing the outer surface of the leg inserted into the penetrated hole; and a rotation driving part which is dropped under the sea surface via the penetrated hole and rotates the leg whose lower end part is stuck and fixated in the sea bed. Additionally, the leg installing method for fixating a ship comprises the steps of: inserting the leg into the penetrated hole formed in the hull; fixating the leg in the penetrated hole by using the clamping part; separating the leg from the clamping part, making the leg drop to the sea bed via the penetrated hole by its own weight and getting the lower end part to be stuck and fixated in the sea bed; forcefully rotating the leg by using the rotation driving part and reducing a friction force applied to the lower end part of the leg stuck in the sea bed; and vertically pulling the leg and recovering the leg from the sea bed by using a lifting device. |
