PROJECT SUMMARY REPORT

New Commissioning HIGH VELOCITY OIL FLUSH SERVICES


Prepared by: Sania Munford


Introduction:

This report documents the New Commissioning High Velocity Oil Flush performed on the Roll Shop Gear Oil Unit.


Objective:

Provide a safe, thorough, and efficient Flush of this system, satisfying all customer requirements.


Results:

  • 3/12 Hour Days Hours worked with ZERO incidents or injuries

  • SFM RS commitment to safety, demonstrated by its safety record, provides refinery owners, construction companies, and OEM’s peace of mind and safety assurance

  • Mutually developed a comprehensive flush plan with all related parties and executed the flush, meeting or exceeding all customer requirements

  • Comprehensive and properly developed flush plan provided peace of mind and assurance that all flush requirements were satisfied, including properly draining and purging all system piping

  • SFM executed the flush, utilizing “purpose built” equipment and superior technical expertise. This helped the customer avoid further schedule slippage during the outage.

  • Provided documentation of flush procedures confirming SFM’s guarantee that all customer criteria were met.

  • This particular HVOF was not performed according to API 614 Flush Standards, as the system was not set up with proper isolation points to install inspection screens. We were only able to achieve target ISO Particle Counts for this flush. But we could not perform the flush to meet API 614 Flush Standards due to the lack of isolation points in the system. This was communicated and documented prior to project award and start.


Filtration:

In addition to nominal “full flow” filtration used on the inlet side of the flush, mobile heater / filter units were used to constantly control oil heat and cleanliness to OEM oil cleanliness. Additional one-micron beta 2000 absolute micro-glass depth media filters were used at the end of the flush to ensure oil cleanliness.


Project Time-Line Overview:


The following pages detail and photo-document the project, including completion of objectives.


The piping and components were flushed to the required specification, cleanliness and acceptance criteria were verified, witnessed and documented. The “Final Flush Acceptance” documents for the system, flushing logs, and photo documentation are included in this report. These documents indicate time duration during various phases of the project, along with the on-site cleanliness level, photo documentation of various aspects of the flush.
