Patent ID: 7438505

Claim:
A heave compensation system to enable the transfer of tubulars between a floating platform and a snubbing jack, the system comprising: a piston having a first end connected to the floating platform and a second end in connection with a traveling slip assembly of the snubbing jack, the piston operable between a disengaged position and an engaged position, wherein when the piston is in the disengaged position the second end is disconnected from physical connection with the traveling slip assembly and the traveling slip assembly moves separate and independent from the movement of the floating platform and when the piston is in the engaged position the traveling slip assembly is locked in a constant position relative to the floating platform; and a tilt cylinder in connection with the piston and the platform, wherein the tilt cylinder moves the second end of the piston between a position for connecting the piston to the traveling slip assembly and a position spaced apart from the traveling slip assembly when the piston is in the disengaged position.
