Abstract
A multi-suction pile anchor and a plate anchor for mooring a marine structure, comprises a plurality of suction piles connected in parallel with the same capacity penetrates into the sea floor, wherein a pullout resistance required for mooring the marine structure is applied by changing the number of suction piles, and wherein a plurality of suction piles is connected each other with a connecting plate to increase a lateral resistance.
Claims1
A method for constructing a multi-suction pile anchor, comprising:
- a step of setting a number of suction piles according to a pullout resistance demanded for mooring a marine structure;
- a suction pile parallel-arrangement step of arranging the suction piles in parallel;
- a suction pile fixing step of integrally coupling a coupling plate to the suction piles, so that the suction piles are integrated;
- a suction pile position fixing step of placing the assembled suction piles on a sea floor to penetrate to a predetermined depth by a weight thereof;
- a suction pile penetration step of pumping water out from a hollow inside of the suction piles through a drainage hole for a suction pressure so that the suction piles penetrate into the sea floor with a designed depth by the suction pressure;
- and
- a marine structure restraining step of connecting a connecting cable connected to the coupling plate, to the marine structure for mooring the marine structure, after the suction piles have entirely penetrated into the sea floor.
