The invention discloses a friction stir welding tool for an overlap joint. The friction stir welding tool is composed of a shaft shoulder and a stirring needle. The stirring needle is shaped like a frustum, the small bottom of the frustum is connected with the shaft shoulder, the end face of the large bottom of the frustum is provided with a round concave hole, and the outer surface of the frustum is provided with three arc-shaped grooves distributed in the circumferential direction. Meanwhile, the invention further discloses the stirring needle and the structures and the sizes of all parts of the shaft shoulder. When a stirring tool designed through the friction stir welding tool is adopted for carrying out friction stir overlap welding, the stirring needle of the frustum shape generates oblique upward thrust on plasticized metal around the overlap face, so that the perpendicular motion of the plasticized metal is reduced, and the perpendicular moving tendency of the overlap face is reduced. Moreover, as the concave hole and the grooves in the side face are formed in the bottom of the stirring needle, material flow in weld zones is improved, the overlap face is broken completely, and the weld metal can be mixed fully. Accordingly, the size of the hook-like defect in a weld joint obtained through welding of the tool is greatly reduced, and the strength coefficient of the joint is remarkably improved.

The disclosure reduces vertical movement of a floating offshore platform by including a centralized open keel plate coupled to the hull that allows water below and above the keel plate. As the floating platform moves vertically, the keel plate separates the water and causes drag on the platform. The water moving vertically with the plate also increases the dynamic mass. The drag results in less vertical movement of the offshore platform without the need to extend legs of the platform to gain an equivalent reduction in vertical movement. The added dynamic mass increases the natural period of the vertical motion away from the wave excitation period to minimize the wave driven motion. The keel plate generally is above or at the same level of the keel, and therefore would not reduce the clearance between the seabed and the keel of the hull at the quayside.
