Abstract
Certain types of riser tensioner arrangements include a high-pressure accumulator; a pusher-type hydraulic cylinder; a first flow path coupling the high-pressure accumulator with a first volume of the cylinder to enable a first high-pressure fluid to flow therebetween; and a second flow path coupling the high-pressure accumulator with a second volume of the cylinder to enable a second high-pressure fluid to flow therebetween. The piston includes a seat and a hollow extension that defines part of the second volume of the cylinder.
