TEMPERATURE GAUGE FOR AN ACCUMULATOR NITROGEN TANK APPARATUS, SYSTEM, AND METHOD

Abstract

A temperature sensor system for a nitrogen tank with a subsea blowout preventer that monitors temperature of the nitrogen in the tank. It is also contemplated to remove rupture discs and utilize a relief valve, which may be assembled with the temperature sensor system.

Claims

1. A subsea piston nitrogen accumulator temperature and pressure system comprising: a subsea nitrogen bottle having an interior, an exterior, and a conduit between said interior and said exterior; a temperature gauge in communication with a sea surface; a pressure gauge in communication with said sea surface; and wherein said temperature gauge and said pressure gauge are in communication with said interior of said nitrogen bottle via said conduit and adapted to read a temperature and a pressure of said interior of said nitrogen bottle and communicate said temperature and said pressure to said sea surface.

DETAILED DESCRIPTION OF INVENTION

[0024] Referring to the illustrations, drawings, and pictures, and to FIGS. 1 and 2 in particular, reference character 10 generally designates a new and improved piston accumulator apparatus, system, and method of using same constructed in accordance with the present invention. Invention 10 is generally used in oil and gas well operations such as but not limited to blowout preventers and may be utilized in other operations not associated with oil and gas drilling operations. For purposes of convenience, the reference numeral 10 may generally be utilized for the indication of the invention, portion of the invention, preferred embodiments of the invention and so on. Invention 10 may also include a new and improved accumulator apparatus, system, and method as well as new and improved blowout preventer apparatus, system, and method.

[0025] Referring now to FIGS. 1 and 2, a dual bottle accumulator 20 is shown with a hydraulic bottle 30, a nitrogen bottle and or tank 40. Invention 10 contemplates providing a relief valve 50, a temperature sensor and or gauge 60, a pressure gauge 70, and so forth. Temperature gauge 60 may be digital, analogue, and or combinations thereof. Temperature gauge 60 may be in communication with the surface for constant monitoring.

[0026] It is further contemplated that relief valve 50, temperature gauge 60, and pressure gauge 70 may be assembled on housing 80 that may be screwed into nitrogen tank 40 but is not limited to such.

[0027] The invention 10 may be a subsea piston nitrogen accumulator temperature and pressure system comprising: a subsea nitrogen bottle having an interior, an exterior, and a conduit between said interior and said exterior; a temperature gauge in communication with a sea surface; a pressure gauge in communication with said sea surface; and wherein said temperature gauge and said pressure gauge are in communication with said interior of said nitrogen bottle via said conduit and adapted to read a temperature and a pressure of said interior of said nitrogen bottle and communicate said temperature and said pressure to said sea surface.

[0028] Changes may be made in the combinations, operations, and arrangements of the various parts and elements described herein without departing from the spirit and scope of the invention. Furthermore, names, titles, headings, and general division of the aforementioned are provided for convenience and therefore, should not be considered limiting.
