The VAF Instruments OILCON MARK6 is a high-precision oil discharge monitoring equipment (ODME) designed specifically for the maritime industry to prevent illegal oil pollution from ballast water and engine room bilges. Utilizing advanced optical sensors and a sophisticated sample conditioning system, it provides real-time analysis of oil content in overboard discharge, automatically stopping the flow if levels exceed international regulatory limits.
Differences from Similar Models
The Mark 6 version represents the latest technological standard from VAF Instruments, offering several improvements over previous generations and competitors:
- Triple Detection Technology: While the Mark 5 and older models often relied on a single light source, the Mark 6 uses multiple scatter angles to accurately differentiate between oil particles, air bubbles, and solid sediment, significantly reducing false alarms.
- Compact Footprint: The Mark 6 “Skid” assembly is more compact than the Mark IV and Mark V systems, allowing for easier retrofitting in crowded engine rooms where space is limited.
- Enhanced Data Security: This model features a tamper-proof digital logbook that complies with the latest MARPOL Annex I regulations, offering more robust data encryption than legacy analog recording systems.
- Self-Cleaning Efficiency: The Mark 6 utilizes a dual-action ultrasonic and freshwater cleaning cycle, which is more effective at preventing bio-fouling and oil film buildup on the sensing glass compared to older mechanical wiper systems.
Product Operation Tips
- Regular Calibration Check: Perform a “zero-point” calibration using fresh water before every discharge operation to ensure the optical path is clear and the sensors are accurately tared.
- Maintain the Sample Pump: The centrifugal sample pump must be checked for prime; running the pump dry can damage the mechanical seals and lead to inaccurate flow readings at the monitor.
- Ultrasonic Cell Care: If the system reports a “Window Dirty” alarm even after a flush, manually inspect the measuring cell for stubborn oil deposits that the automatic cycle may have missed during heavy bilge processing.
- Replace Consumables: Ensure that the specific VAF-approved chemical reagents (if used in your specific configuration) and filters are replaced according to the hour-meter alerts to maintain the validity of the IMO certification.
