The KSB Oil Discharge Monitoring Equipment (ODME S-3000) is an advanced system used on board ships to monitor and control the discharge of oily water mixtures into the sea. It ensures compliance with international maritime pollution prevention regulations, specifically MARPOL Annex I, which governs the discharge of oil from ships. The ODME S-3000 detects the oil content in water being discharged overboard and ensures that it stays within the permissible limits.
