This article, by the Emergency Response Advisor of Shell Exploration and Production, Aberdeen, explains the contingency arrangements which exist to deal with emergencies in the North Sea. The contingency planning aims to prevent emergencies happening so that lives, property, and the environment are not at risk. Or, if a situation develops into an emergency, an effective contingency plan will minimize the risk. In an emergency the Co-ordinator is responsible for mobilizing support in resolving the problem and he has the authority to commit such resources as he deems necessary to resolve it. Training and exercising are essential if the response is to be effective. Public Affairs is also part of the Emergency Response Team.
