Ships produce a significant volume of waste oil originating from various sources, including engine lubrication, fuel usage, and mechanical operations, as reported by Marine Insight.
Proper Waste Management Practices on Ships:
- Prohibited Discharge: Ships are strictly prohibited from dumping or pumping oil overboard to avoid legal consequences.
- Segregation of Waste: Waste oil is separated into sludge and bilge tanks on ships for proper management.
- Bilge and Sludge Tanks: Bilge and sludge tanks store mixtures of oil and water, with sludge containing a higher oil content.
- Tank Heating and Water Separation: Tanks on ships are equipped with heating arrangements to control oil viscosity and separate water from the oil.
- Drainage of Heavy Water: Tanks are drained to remove settled heavy water, which is then directed to bilge tanks for further treatment.
- Centrifugal Separator: Fuel undergoes treatment in centrifugal separators, separating impurities such as sludge and water, which are then sent to the sludge tank.
- Machinery Leakages: Oil leakages from machinery are collected and directed to the appropriate tank based on the oil quantity.
- Oily Water Separator (OWS): Bilge water can be treated using onboard equipment called an oily water separator, which filters water through multiple stages of filtration.
