Title: Innovations by Erstad Jostein in High-Pressure Fluid Sealing Technology

Introduction

Erstad Jostein is a notable inventor based in Bergen, Norway. He has made significant contributions to the field of high-pressure fluid sealing technology, particularly in the oil and gas industry. With a total of three patents to his name, Jostein's work focuses on enhancing the reliability and efficiency of fluid connectors.

Latest Patents

One of Jostein's latest patents is a dynamic sealing arrangement designed for connectors that carry high-pressure fluids. This innovative sealing arrangement features a primary and a secondary U-shaped hydraulically operated sealing ring. The design ensures that the open sides of the seals face away from the junction of the connectors, directing the fluid leakage path. By supplying barrier fluid at a pressure higher than that of the production fluid, the primary seal is activated under pressure differential conditions. The secondary seal remains inactive during normal operations, thus preventing wear and only engages if the primary seal fails. This design leads to substantial cost savings by ensuring the integrity of the sealing system.

Another significant patent is a monitoring system for high-pressure fluid flow connectors. This system is capable of maintaining the integrity of the seal at junctions between fluid conduits. It generates warning signals or activates a secondary seal in the event of main seal failure. The monitoring system utilizes a hydraulic seal with barrier fluid supplied under pressure. By sensing the pressure of the barrier fluid and comparing it to the applied pressure, the system can detect leaks accurately and timely. This innovation is particularly beneficial when multiple junctions are present in a connector, as it allows for independent supplies of barrier fluid to each seal.
