A subsea tensioner system that includes a one or more spring activated piston return subsea tensioners. The subsea tensioner system can use a spring activated subsea tensioner because the subsea tensioner system uses non-toxic fluid to drive a piston disposed within the subsea tensioner, and when the piston reaches a second position a fluid release valve is opened thus allowing the fluid used to drive the piston to be emptied into the local underwater environment. The subsea tensioner system eliminates the need for topside trips to return the piston to an initial position to take another stroke.

Subsea tensioner system

A method for automatically cycling a torque wrench. The method includes providing a hydraulic torque wrench. Providing an actuating device on the hydraulic torque wrench. Providing a switching device on the hydraulic torque wrench. Adapting the switching device to be activated by the actuating device when a piston of the torque wrench is at the end of a stroke. The embodiments of the method allow a user to ensure that a proper torque on a threaded fastener is achieved. This ensures that the pressure achieved within the system is a result of a proper torque applied to a threaded fastener being achieved, and not a result of the piston at the end of its stroke.
