An accumulator for hydraulically actuating subsea equipment includes a hydraulic fluid chamber and a gas chamber. The hydraulic fluid chamber is in fluid communication with the subsea equipment and comprises a hydraulic piston slidably received, at least partially, within the hydraulic chamber. The gas chamber comprises a charge piston slidably received within the gas chamber, the charge piston dividing the gas chamber into a first portion and a second portion. The first portion of the gas chamber is configured to receive ambient hydrostatic pressure therein, and the second portion of the gas chamber is configured to receive precharge gas therein.

1. An accumulator for hydraulically actuating subsea equipment, the accumulator comprising: a hydraulic fluid chamber in fluid communication with the subsea equipment and comprising an inner cavity;a gas chamber with an inner cavity larger than the inner cavity of the hydraulic fluid chamber;a hydraulic piston slidably received, at least partially, within the hydraulic fluid chamber;a charge piston slidably received within the gas chamber;the hydraulic piston and the charge piston forming a precharge volume therebetween. 2. The accumulator of claim 1, further comprising: a hydraulic fluid port in fluid communication between the hydraulic fluid chamber and the subsea equipment; anda pressure port for receiving pressure to provide a force on the side of the charge piston opposite from the hydraulic piston. 3. The accumulator of claim 2, wherein the pressure port receives ambient pressure to provide a force on the opposite side of the charge piston from the precharge gas. 4. The accumulator of claim 3, further comprising: a valve selectively controlling the exposure of the pressure port to ambient pressure. 5. The accumulator of claim 1, wherein the precharge volume is pressurizable by a precharge gas between the hydraulic piston and the charge piston. 6. The accumulator of claim 1, further comprising: a precharge pressure port for receiving the precharge gas between the hydraulic piston and the charge piston. 7. The accumulator of claim 1, wherein the hydraulic piston and the charge piston are separable from each other. 8. The accumulator of claim 1, wherein the hydraulic piston includes a small diameter portion slidably and sealingly mounted in the hydraulic fluid chamber and connected to a larger diameter portion slidably and sealingly mounted in the gas chamber. 9. The accumulator of claim 1, wherein the hydraulic piston is fully received within the hydraulic fluid chamber. 10. The accumulator of claim 1, wherein the hydraulic piston and the charge piston are coupled to prevent relative movement therebetween. 11. An accumulator for hydraulically actuating subsea equipment, the accumulator comprising: a hydraulic fluid chamber in fluid communication with the subsea equipment and comprising a hydraulic piston slidably received, at least partially, within the hydraulic chamber; anda gas chamber comprising a charge piston slidably received therein, the charge piston dividing the gas chamber into a first portion and a second portion;the first portion of the gas chamber being configured to receive ambient hydrostatic pressure therein; andthe second portion of the gas chamber being configured to receive precharge gas therein. 12. The accumulator of claim 11, further comprising a body with the hydraulic fluid chamber and the gas chamber formed within the body, and wherein the hydraulic piston and the charge piston sealingly engage the body, the body further comprising: a hydraulic fluid port in fluid communication between the hydraulic fluid chamber and the subsea equipment; anda pressure port for receiving ambient pressure to provide a force on the side of the charge piston opposite from the hydraulic piston. 13. The accumulator of claim 12, further comprising: a valve selectively controlling the exposure of the pressure port to ambient pressure. 14. The accumulator of claim 11, wherein the hydraulic piston and the charge piston are separable from each other. 15. The accumulator of claim 11, wherein the hydraulic piston is fully received within the hydraulic fluid chamber. 16. The accumulator of claim 11, wherein the hydraulic piston and the charge piston are coupled to prevent relative movement therebetween. 17. The accumulator of claim 11, wherein the gas chamber comprises an inner cavity larger than an inner cavity of the hydraulic fluid chamber. 18. An accumulator for a subsea blowout preventer unit including a blowout preventer, comprising: a body including a hydraulic fluid chamber and a precharge gas chamber, wherein the hydraulic fluid chamber has a smaller inner diameter than the precharge gas chamber;a hydraulic fluid port in fluid communication between the hydraulic fluid chamber and the subsea blowout preventer;a hydraulic piston slidably and sealingly mounted in the hydraulic fluid chamber;a charge piston slidably and sealingly mounted in the precharge gas chamber and unconnected with the hydraulic piston; anda pressure port for receiving pressure to provide a force on the opposite side of the charge piston from the hydraulic piston. 19. The accumulator of claim 18, wherein the precharge gas chamber is pressurizable by a precharge gas disposed between the hydraulic piston and the charge piston. 20. The accumulator of claim 19, wherein the pressure port receives ambient pressure to provide a force on the opposite side of the charge piston from the precharge gas.
