Abstract
A pressure-compensated fuse assembly may include a first chamber housing a first fluid and a plurality of solid particles. Additionally, the fuse assembly may include a second chamber housing a second fluid. Further, the fuse assembly may include a pressure compensator disposed between the first chamber and the second chamber. The pressure compensator may be configured to transfer pressure from the second fluid in the second chamber to the plurality of solid particles in the first chamber.
Claims28
A pressure-compensated fuse assembly, comprising:
- a first chamber housing a first fluid and a plurality of solid particles;
- a second chamber housing a second fluid;
- and
- a pressure compensator disposed between the first chamber and the second chamber, wherein the pressure compensator is configured to undergo a movement to transfer pressure from the second fluid in the second chamber to the plurality of solid particles in the first chamber, and the plurality of solid particles block the movement of the pressure compensator.
A fuse system, comprising:
- a first housing comprising a first chamber having a fuse element, a first fluid and a plurality of solid particles;
- a pressure compensator coupled to the first housing, wherein the pressure compensator is configured to undergo a movement to transfer pressure from a second fluid outside of the first chamber to the plurality of solid particles in the first chamber and the plurality of solid particles block the movement of the pressure compensator.
A subsea mineral extraction system, comprising:
- a pressure-compensated fuse assembly configured to be disposed in a subsea location, wherein the pressure-compensated fuse assembly comprises:
- an outer housing;
- an inner housing disposed within the outer housing, wherein the inner housing comprises:
- a first chamber having a first fluid;
- a sleeve disposed circumferentially around the first chamber;
- and
- a piston disposed within the sleeve, wherein the piston is configured to translate relative to the sleeve;
- and
- a second chamber having a second fluid, wherein the second chamber is disposed in the outer housing, and wherein the piston is disposed between the first chamber and the second chamber.
A system, comprising:
- a pressure-compensated fuse assembly, comprising:
- a first chamber containing a gas and a plurality of solid particles;
- a sleeve disposed around the first chamber;
- a second chamber containing a dielectric fluid;
- a piston disposed within the sleeve and between the first chamber and the second chamber, wherein the piston is configured to translate relative to the sleeve;
- and
- a flexible metal seal coupling the piston to the sleeve, wherein the flexible metal seal that seals off an annulus between the piston and the sleeve to separate the gas and the plurality of solid particles in the first chamber from the dielectric fluid in the second chamber.
