Product Usage Instructions

Start Procedure

Turn the Process switch to OFF.
Flush OCM and ensure reading 0 ppm. Close sample valves before
and after OCM.
Simulate flow through the flow switch by loosening the screw on its sensor and adjusting it until indication (96) is lit.
Restart the separator on the process switch. Overboard valve (6) will now open, and there shall be flow from the port state control valve.
Open the lid of the OCM and pour a small amount of high ppm liquid into the OCM (Formazin etc).
When the ppm value increases above the set point, the overboard valve (6) shall immediately close, and the return valve (7) open. Visually confirm no flow from the port state control valve. After 10 seconds, the separator shall stop and give the alarm to ECR.

Reset Back to Normal Operation

Turn the process switch to OFF. Flush the OCM and confirm a reading of 0 ppm. Adjust the flow switch back to its original position and make sure (96) is not lit.
Reset the alarm for 1 to 4 minutes.
Open the sample valves and start the separator on the process switch. Confirm the overboard valve is opened when there is flow through the flow switch (96) and the ppm value is below the set point.

FAQ

Q: What should I do if the ppm value does not increase above the set point during the start procedure?
A: If the ppm value does not increase, check the connections, ensure proper calibration of the equipment, and verify that the high ppm liquid is added correctly.
Q: Why is it important to reset the flow switch back to its initial position after testing?
A: Resetting the flow switch ensures that sample flow through the OCM is maintained at all times as required by regulations, preventing any potential issues during operation.

Operation Instruction

Operation instruction of Marinfloc CD at Port State inspection
System applicability: Marinfloc CD standard, all models with oil content meter type Deckma OMD‐2005 fitted.

Start procedure

Turn on the heating, air, and water supply. Clean the OCM and flush it. Confirm that the reading is 0 ppm on fresh water and close the valves on the sampling line to avoid dirty water into the meter during start-up. Confirm the alarm delays on the OCM by pushing and then . Set the alarm for 1 to 10 seconds, and the alarm to 2 to 1 second.
Start the separator to warm it up. Turn all switches into “AUTO” and process switch in “ON”. The system starts and the start delay is active for 20 seconds. During start-up valve no. 58 will be open until the water temperature reaches 40 °C inside the circulation tank.
Ensure that the ship’s overboard valve is closed and open the port state control valve so that overboard flow can be visible through this valve into a funnel or sight glass.
When the water has risen to 40 °C, the water will continue to the flocculation tank and then run for recirculation (139) for 15 minutes. This is to ensure clean water to the filters. If the water is clean in the recirculation sight glass, the filtering can also be started by manually turning the S3 switch to filtering.
When filtering (140) has started, it is normal with high ppm during the first minutes after start-up. It is then recommended to take a sample of the filtrated water before opening the valves on the sampling line to OCM. Take the sample at the outlet of the third filter (from the drain valve or test cock at valve 27). The water must be very clear!
Confirm that the flow switch (96) is not active when the sample valves are closed.
Open the valves on the sampling line and ensure that the flow switch (96) is lit.
If the flow switch is activated and the ppm value is below the set point, the overboard valve shall now open. Confirm a visible flow from the port state control valve.
Close the sample valves and confirm that the overboard valve closes. Visibly confirm that there is no flow from the port state control valve.
Turn the Process switch into “OFF”. Flush OCM and ensure reading 0 ppm. Close sample valves before and after OCM.
Simulate flow through the flow switch by loosening the screw on its sensor and adjusting it until indication (96) is lit.
Restart the separator on the process switch. Overboard valve (6) will now open and there shall be flow from the port state control valve.
Open the lid of the OCM and pour a small amount of high ppm liquid into the OCM (Formazin etc).
When the ppm value increases above the set point, the overboard valve (6) shall immediately close and the return valve (7) open. Visually confirm no flow from the port state control valve. After 10 seconds separator shall stop and give the alarm to ECR.
- Important! The above-described adjustment is only for testing the automatic stopping device.
- The flow switch’s purpose is to ensure sample flow through the OCM at all times. This is a requirement in MEPC.107(49) regulation (see below extract).
- § 6.2.2 The arrangement on board ship for the extraction of samples from the 15 ppm Bilge Separator discharge line to the 15 ppm Bilge Alarm should give a truly representative sample of the effluent with adequate pressure and flow.
- Thus, it is the operator’s responsibility to ensure that the flow switch is reset to its initial position after the test.
  Reset back to normal operation
Turn the process switch to OFF. Flush the OCM and confirm the reading of 0 ppm Adjust the flow switch back to its original position and make sure (96) is not lit.
Reset the alarm for 1 to 4 minutes.
Open the sample valves and start the separator on the process switch. Confirm the overboard valve is opened when there is flow through the flow switch (96) and the ppm value is below the set point.

Always keep the system in good condition. Flocculation must work at all times. Get familiar with the system and practice the above instructions regularly and before the inspection – this will simplify the port state inspections.
