PROJECT SUMMARY REPORT

HIGH VELOCITY OIL FLUSH SERVICES ABB STAL VAX STEAM TURBINE


This report documents the High Velocity Oil Flush performed on the ABB STAL VAX Steam Turbine at Gulf Coast Cogen Facility.



Objective:

Provide a safe and efficient Flush of these systems, satisfying all customer requirements.


Results:

▪ 255 Man Hours worked with ZERO incidents or injuries o SFM Reliability Solutions (SFM RS) commitment to safety, demonstrated by its safety record, provides plant 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 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 RS executed the flush utilizing purpose-built equipment and superior technical expertise. This helped the customer avoid schedule extensions during the outage.


▪ Provided documentation of flush procedures confirming SFM RS guarantee that all customer criteria were met.


Filtration:

In addition to one-micron 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.
