Assessment Methodologies for Potentially Polluting Wrecks: The Need for a Common Approach
摘要
There are believed to be more than 8500 Potentially Polluting Wrecks (PPW) lying on the seabed around the world, including many oil tankers, which potentially still contain very large quantities of oil. With many of these wrecks having been submerged for nearly 80 years (and sometimes more), the condition of their hulls is continuing to deteriorate, which combined with the increase in the frequency of severe weather events, means that the risk of significant pollution is increasing, particularly for wrecks in shallower waters.
