Turnarounds are often the perfect time to perform much needed maintenance on the lube oil systems of critical hydraulic and rotating equipment.
While systems are scheduled to be down and offline for several days, hydraulic and lube oil reservoirs can be drained, and experienced crews can then perform confined space entry tank clean-outs. At the same time, the oil can be thoroughly filtered to remove all particulate and moisture contamination, using High Flow Filter Skids and/or Vacuum Dehydrators. Afterwards, clean and dry oil that meets strict OEM cleanliness specifications can be pumped back into a clean reservoir.
If deemed necessary, a complete High Velocity Oil Flush or Varnish Removal Flush can be performed to remove all contamination from the hydraulic and lube oil piping as well (not just the oil and the reservoir). This is a more involved procedure that typically requires more time and planning, but sometimes it is the only way to bring the entire system back to “like new” cleanliness standards, especially when varnish deposits have plated out on hard metal surfaces within the hydraulic or lube oil system.
