Abstract

An accumulator for subsea wellbore operations including a generally cylindrical housing having a first and second longitudinal end each having a fluid port. The housing is divided into two sections by a bulkhead. A first piston is disposed on one side of the bulkhead and a second piston is disposed on the other side of the bulkhead. A connecting rod disposed between piston and defines an atmospheric pressure or vacuum chamber in a longitudinal end in contact with the second piston. The first piston defines an hydraulic fluid chamber and a gas charge pressure chamber between it and the bulkhead. The second piston defines a hydrostatic pressure chamber between it and the second longitudinal end of the housing. The first and second pistons having substantially equal cross sectional areas on both sides thereof such that a pressure of fluid in the hydraulic fluid pressure chamber is substantially equal to a pressure of gas in the gas charge pressure chamber and a hydrostatic pressure applied to the hydrostatic pressure chamber.
