Lubricant discharges

摘要

Basic calculations presented at IMO's Marine Environment Protection Committee (MEPC) meeting in 2008 suggested that 80 million litres of oil-based lubricants are lost at sea annually from stern tubes. However there has been little in the way of follow-up authoritative research on this or other lubricant pollution to guide policymakers. This study focuses on operational discharges of lubricant oils within ports and harbours. It excludes those occurring en route, because the monitoring and recording of small discharges at sea is relatively poor, making any data analyses inaccurate. The study also only includes the leakage and operational discharge of lubricants in their day-to-day application. It excludes accidental spills from vessels or spills of stored lubricant oils.
