Suitable for subsea artificial foundation gravity platform

The present invention discloses a subsea gravity applied to artificial foundation platform. It comprises a recess, with the lower recess of the mat gravity platform matches; lower portion of the gravity platform inclined bottom mat shape; base bottom connected to the bottom of the groove. Its production method, comprising the steps of: cleaning the seabed soil surface to give a space, and the inclined side wall of the control space form; the following step 1) or 2), i.e., subsea artificial foundation obtained: 1) in a space produced recesses, and filling sand in the cavity between the sidewalls of the groove with the space; 2) into the space at the bottom of the bottom base, then making space in the recess, and the side walls of the groove and space filling the cavity between the sand. The present invention has the following advantages: when a gravity platform fixed to ensure that the level of gravity of the platform and stability, solves the problem of erosion is easily emptied of its bottom; a movable platform, displacement, simple reduction and disposal; reducing the cost of practical application.
