ABSTRACT:
A subsea suction pile crane system comprises a suction pile and a crane mounted on the suction pile. The crane comprises a rotatable mounting surface, a winch, and a boom having a proximal section attached to the rotatable mounting surface such that the boom can pivot with respect to the mounting surface, and a distal section opposite the proximal section. In embodiments, a plurality of suction piles may be sed. The crane system is typically hydraulically operated. A preferred embodiment of the invention may further comprise a remotely operated vehicle comprising a hydraulic power supply operatively coupled to the crane, and a manipulator arm mounted on the distal section of the boom and operatively coupled to the hydraulic power supply.
