We board cargo vessels greater than 300 gross tons. Our priority is to board the vessels that we have ranked as higher risk. We assign vessels with a risk score based on their age, inspection history, past incidents, and spill history. This risk score combined with other factors, such as whether we’ve inspected them before, helps determine if we will board a vessel.
Currently we don’t inspect tank vessels for substantial risk. However, tank vessels are invited to join Washington state’s voluntary Exceptional Compliance Program.
Any vessel which spills oil into state waters will be inspected to determine the cause of the spill and how much was spilled.
