OICEW-A5.3 Oily-water separators (or similar equipment) requirements and operation

Condition Behavior Standard

On a vessel of at least 1,000 HP, on a simulator, or in a laboratory,

the candidate monitors the oily- water separator system.


The assessment is required for all OICEW endorsements regardless of any limitations for propulsion mode and/or vessel equipment.

The candidate:

  1. Checks plant’s operational status;

  2. Checks bilge-water tank level;

  3. Checks oily-water-separator chamber pressure or vacuum;

  4. Checks filling related pressure/vacuum;

  5. Checks overboard-discharge water-pump pressure;

  6. Monitors oil-content monitor and ensures that:

  7. Equipment is not bypassed, sampling line is open, and flushing water is not being supplied to sensor;

  8. Automatic valves are not operated in manual mode or disconnected from controlling devices; and

  9. No temporary hoses are used during operation and when possible, checks cleanliness of sensors;

  10. Checks for any unusual conditions or noises;

  11. Notifies watch engineer of any unusual or unsafe conditions; and

  12. Takes proper action to prevent safety and pollution violations.
