Average number of major oil spills (over 700 tonnes)

Important advances have been in the design of oily water separating equipment for machinery space bilges and oil tanker discharges, and in the monitoring and control of the discharge of such mixtures. These technological advances have allowed international regulations to be adopted, reducing the permitted operational discharge of oil effluent from machinery space bilges from 100 parts per million (ppm) to 15ppm.
