Wharton, Texas EHC Decontamination

Overview

Frontline Global Services was engaged by a client based in Wharton, Texas, USA to execute a comprehensive fluid services project on one (1) steam-driven turbine generator EHC system. Services included fluid evacuation, reservoir decontamination, high-velocity flushing, and fluid purification to meet specified ISO cleanliness levels. The project was completed efficiently with all fluid cleanliness targets achieved and validated.

Project Objectives

Safety and Efficiency

Efficiently minimize equipment downtime while ensuring all operations are conducted safely, protecting personnel and equipment.

Perform High-Velocity Oil Flushing

Ensure all contaminants are flushed out from the EHC system lines and components.

Purify Existing System Fluids

Ensure that any remaining fluids meet OEM cleanliness specifications.

Cleanliness Standards

Achieve a final particle count of 16/14/11 or better, per industry standards (API 614), and ensure clean screens free of particulates.

Methodology

Frontline utilized proprietary high-velocity flushing equipment and fluid purification technologies, including specialized high-velocity filtration units (HVFU), high-quality stainless double armor guard hoses, and real-time particle counting to meet stringent cleanliness standards. System flushing targeted Reynolds numbers (Re) greater than 20,000, achieving API 614 compliant screens and particle counts as per ISO 4406.

Process

1. Reservoir Decontamination (Initial): Initial cleaning and flushing of the reservoir to remove major contaminants and construction debris.

   
   

2. High-Velocity Oil Flush: Executed flush across fluids. Targeted Reynolds number (Re) >20,000 ensuring turbulent flow conditions

   
   

3. Reservoir Decontamination (Final): Secondary flushing and inspection to ensure the reservoir meets required cleanliness specifications.

   
   

4. Fluid Purification Process: Circulate and filter existing or newly added fluids to ensure they meet ISO 16/14/11 or better.

   
   

5. Final Fluid Fill: System re-inventoried with new, purified Fyrquel EHC Plus fluid, meeting OEM standards.

   
   

Project Summary

Efficient & Safe

Timely execution, proven methodology, and delivery of a thoroughly cleaned and tested system satisfied our customer’s operational and cleanliness standards, all done in a safe and fast manner.

Increased Equipment Reliability

By removing built-up contaminants, the assets are now better positioned to operate at optimum efficiency and reduce the risk of downstream issues.

Clean Screens & Particle Counts

The final particle counts for the assets were below 16/14/11, meeting and exceeding the customer’s requirements.

Conclusion

Frontline Global Services successfully executed the High-Velocity Flushing and maintenance process on the turbine EHC system. The project serves as a testament to Frontline’s turnkey, results-oriented execution model and commitment to safety and quality.
