Abstract
A pyrotechnic pressure accumulator includes an elongated body extending from a first end of a pyrotechnic section to a discharge end of a hydraulic section. A propellant charge located in a gas chamber of the pyrotechnic section, a piston movably disposed the hydraulic section, and a fluid disposed in a hydraulic chamber between the piston and the discharge end, wherein the fluid is exhausted under pressure through a discharge port in response to ignition of the propellant charge.

A pyrotechnic pressure accumulator, comprising:
- an elongated body extending from a first end of a pyrotechnic section to a discharge end of a hydraulic section;
- a propellant charge located in a gas chamber of the pyrotechnic section;
- a piston movably disposed the hydraulic section;
- and
- a fluid disposed in a hydraulic chamber between the piston and the discharge end, wherein the fluid is exhausted under pressure through a discharge port in response to ignition of the propellant charge.
A pyrotechnic pressure accumulator, comprising:
- an elongated body extending from a first end of a pyrotechnic section to a discharge end of a hydraulic section;
- a breech chamber located in the pyrotechnic section between the first end and a breech barrier having a breech orifice;
- a propellant charge located in the breech chamber;
- a snubbing chamber formed in the pyrotechnic section between the breech barrier and a snubbing barrier having a snubbing orifice;
- a piston movably disposed the hydraulic section;
- a fluid disposed in a hydraulic chamber between the piston and the discharge end, wherein the fluid is exhausted under pressure through a discharge port in response to ignition of the propellant charge
A method, comprising:
- activating a pyrotechnic pressure accumulator to supply a hydraulic pressure to device in a subsea well system, the pyrotechnic pressure accumulator comprising:
- an elongated body extending from a first end of a pyrotechnic section to a discharge end of a hydraulic section;
- a propellant charge located in a gas chamber of the pyrotechnic section;
- a piston movably disposed the hydraulic section;
- and
- a fluid disposed in a hydraulic chamber between the piston and the discharge end;
- igniting the propellant charge;
- and
- pressurizing the fluid and discharging the pressurized fluid through a discharge port to the device in response to igniting the propellant charge.
