Abstract:
A semi-submersible support platform and a positioning method thereof are disclosed. The semi-submersible support platform, used for operations at sea after sailed to a certain position of a sea surface, includes an upper deck and a lower pontoon. The upper deck and the lower pontoon are connected by a plurality of upright columns. Each upright column is provided with a support leg that is longitudinally inserted through the upright column. The lower pontoon has a plurality of chambers for receiving water therein. The support leg has a compartment for receiving water therein. Each upright column includes a leveling mechanism therein. When the support leg sinks to reach the seabed, the leveling mechanism in each upright column is combined with the support leg to support the support leg. The leveling mechanism can drive the upper deck to move up or down along the support leg.

Claim (Index 4):
A positioning method of the semi-submersible support platform as claimed in  claim 3 , wherein after the semi-submersible support platform is sailed to the certain location of the sea surface, the compartment of the support leg is filled with water and then sinks to reach the seabed, the leveling mechanism in each upright column is combined with the support leg to support the support leg, after the plurality of chambers inside the lower pontoon are filled with water, the support leg inserted through each upright column sinks further, the leveling mechanism can drive the upper deck to move up or down along the support leg until the upper deck is horizontal; for the upper deck to move up, the positioning rods of the lower positioning cylinders respectively extend into the positioning holes of the support leg, and the positioning rods of the upper positioning cylinders are removed out of the positioning the holes, and the plurality of jacking cylinders drive the upper seat away from the lower seat for driving the upper deck to move up, after the upper deck is positioned, the positioning rods of the upper positioning cylinders extend into the positioning holes to be positioned; for the upper deck to move down, the positioning rods of the lower positioning cylinders respectively extend into the positioning holes of the support leg, and the positioning rods of the upper positioning cylinders are removed out of the positioning holes, and the jacking cylinders drives the upper seat close to the lower seat for driving the upper deck to move down, after the upper deck is positioned, the positioning rods of the upper positioning cylinders extend into the positioning holes to be positioned.
