Description This focus sheet describes ship domains that we may use as part of our oil spill risk model. A ship domain is an area around a ship that should be free of other vessels. If two ship domains overlap, then the model counts that event as an encounter.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
