High pressure, high voltage penetrator assembly

Abstract

The invention relates to a high pressure, high voltage penetrator assembly for subsea, topside or land based use, wherein the assembly is upright attachable to a wet gas and / or liquid handling compressor or pump or to / from a transformer, and wherein the assembly comprises a penetrator unit for feed-through of electric power to a motor of the compressor or pump or to / from the transformer; a funnel shaped housing with a housing chamber, the penetrator unit being located at an upper end of the chamber; a grid located inside the chamber transversely of a longitudinal axis of the chamber, the penetrator unit being located above the grid, a filter located in the chamber below the grid and above an inlet to a housing of the motor or to / from a housing of the transformer, and a sensor unit extending into the chamber from the penetrator unit and towards, but spaced from the grid.

Description

technical field [0001] The present invention relates to a high pressure, high voltage penetrator assembly as defined in the preambles of claims 1 and 22 appended hereto. Furthermore, the invention also relates to a high pressure, high voltage penetrator for use in the penetrator unit of said assembly as defined in the preambles of claims 14 and 17 . Background technique [0002] To stabilize and increase the delivery of hydrocarbon process fluids, such as gas (wet gas) or liquids from subsea or waterline production wells, compressors or pumps are usually installed downstream of crude liquid separation. The compressor or pump requires a drive motor with a high power rating, typically in the current range of 500-2000A and voltage range of 6.6-12kVAC. Furthermore, during the transport of hydrocarbon fluids over long land-based distances, flow intensifiers or pumps are often required at regular intervals in order to stabilize the flow under various geographically difficult cond...

Problems solved by technology

In a worst case scenario, such operating conditions could lead to the ignition of said process gas and an explosion with catastrophic consequences

[0005] In addition, rapid depressurization can occur, for example during wet gas production, as a result of which equipment such as O-rings and electrical insulation exposed to high pressure can explode, resulting in catastrophic destruction of said compressor or pump subsea installations Earth collapse

[0006] Whereas on the one hand fluids need to be extracted with optimum effect from production wells and hence the pressure in said production wells needs to be increased in order to discharge said fluids from the reservoir, and on the other hand subsea compressor / pump units have to work at Harsh and dangerous environments, so a related problem in this professional field is that operational failure is about to occur without being detected in time to take measures to prevent it. This problem has existed for many years and remains unsatisfactory solutions to overcome the well-known operational problems described
