Consequences of the pollution

Worldwide, between 1974 and 1989, there were 774 accidents involving oil spills greater than 7 tonnes. Since 1970 there have only been two major spills (more than 1000 tonnes) in Australia. The following table indicates the number of reported spills and responses pursuant to the National Plan between 1994/95 and 1998/99.

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.

The introduction of industry practices such as crude oil washing for oil tankers, coupled with segregated ballast requirements for tankers, has contributed significantly towards reducing operational pollution. The entry into force of the international convention MARPOL 73/78 is credited with a substantial positive impact in decreasing the amount of oil that enters the sea from maritime transportation activities.
