Summary: | A surface assembly that communicates with subsea structures and includes a working deck on a floating structure. The working deck has an aperture extending axially therethrough. A riser extends from a subsea location to the working deck and through the aperture. The surface assembly includes a frame extending circumferentially around the riser so that the frame moves axially with the riser. The assembly also includes a tensioner assembly connected between the working deck and the frame. The tensioner assembly has a piston, a piston chamber, and a piston rod extending from the piston and away from the piston chamber. A shroud encloses and moves in unison with the piston rod. |
