Abstract
A jack system may provide subsea or surface operation. The jack system includes a top plate and a base plate with at least two pistons disposed between the base and top plate. The pistons are extendable to increase a separation distance between the base and top plate, and said pistons are retractable to decrease the separation distance between the base and top plate. The jack system also includes a bottom slip bowl assembly, a top slip bowl assembly, and rotary assembly. The top slip bowl and rotary assembly are rotatably coupled to the top plate wherein the rotary assembly and the top slip bowl assembly rotate relative to the top plate.
