–Disposal of oil residues from oily bilges and slop tanks
- Don’t allow solvents or detergents to get into bilge or slop water. They interfere with oily water separator operation.
- Don’t discharge slop tank if contents have emulsified or foamed. Emulsions can be separated by a slow heating of the slop tank.
- Don’t discharge bilge waste in “Special Areas.”
- Don’t discharge bilge waste if oily water separator or monitor is not working.
- Don’t bypass discharge monitor for regular discharges. (In a flood emergency, the pump shutoff function of the discharge monitor may not be bypassed to keep the bilge pumps running. The monitor must still be recording.)
- Use port facilities for oily bilge and slop tank waste.
- Properly maintain and use oily water separator to remove oil from bilge.
- Only discharge to the sea during daylight hours, and watch for an oil sheen.
- Shut off discharge pump if oil sheen is visible.
- Maintain equipment in engine room so that oil leakage and drainage into bilge are minimized; for example, do not overfill oil reservoirs.
