Abstract
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.
