SECCO is a joint venture petrochemical company invested by SINOPEC &BP in Shanghai, China manufactures ethylene, propylene, polyethylene, polypropylene, styrene, polystyrene, acrylonitrile, butadiene, benzene, toluene etc. Units Basic Info – Units: Mitsubishi compressor -Reservoir: 20000L (Turbine oil) -Oil years: 3 years
The aging lube oil was heavily degraded and particle contaminants and varnish already formed in the lubrication system Due to the increased friction, engineers highly concerned about the elevating temperature (106℃) of thrust bearings. Also, they found a darkened varnish stuck on the surface of thrust bearings (See picture 1) in last inspection during scheduled outage. To avoid costly unscheduled trips, SECCO decided to solve it with reliable solutions.
Winsonda’s varnish removal unit has been introduced and installed to the centralized reservoir on 17th Oct. 2016 for 11C3801/11CST3901/11CST3601.
With 37 days operation, the temperature of thrust bearings dropped to safety levelThe independent test was performed by SGS and oil analysis report indicated an excellent value varnish potential ΔE=1.2. Customer was pleased to have such result and placed repeated order for another three units.
CNOOC (SHENZHEN), AN OFFSHORE OIL PLATFORM(#32-2)
Units Basic Info
– Units: Solar T60
-Oil Type: Caltex Regal R&O 46
-Reservoir: 1800L
The oil analysis report showed that the in-service oil was highly contaminated by particles and serious varnish formation. The pressure of EHC system was unstable during operation. To prevent key components damage caused by lubrication failure, engineer come to us for a filtration solution.
Winsonda’s varnish removal unit(WVD-II) has been introduced and installed to the reservoir in 7 th Dec. 2016 for continuous filtration.
After 7 days filtration, the MPC value Δ E dropped from 31.5 to 4.4. The cleanliness has been improved to ISO Code 15/13/9 . Customer was pleased to see stable working pressure in operation. Also oil was free of particles and varnish which greatly increased machine reliability and the life of key components.

Aiming at building and operating a world-class, high-tech integrated petrochemical facilities, client pays close attention to equipment breakdown caused by lubricant failure. They wanted to build up proactive maintenance program to improve machine’s reliabilities. Oil analysis showed in-service oil was high contaminated with particles (ISO CODE 20/18/13) and varnish formation would accelerate the friction of moving components, servo valve failures etc.
In order to remove the particles and prevent varnish/sludge from deteriorating, Winsonda’s varnish removal unit has been introduced and installed to the reservoir in Oct. 2017 for continuous filtration.
After 20days filtration, the MPC value Δ E dropped from 16.5 to 10. The cleanliness has been improved to ISO Code 16/13/10 . Another two months later, client informed a better MPC 8.2. Utilizing Winsonda’s WVD-II to restore the oil system free of particle and varnish that extend the maintenance interval with large cost savings.
