I can confirm that there are thoroughly tested plans in place to deal with safety issues in respect of submarines operating around the coastal waters of Scotland. The Clyde Public Safety Scheme and the Rosyth Public Safety Scheme are the two most significant examples. These are published documents and are available in these two areas in public libraries. The contingency plans are designed to respond to a wide range of possible scenarios, to address the full range of known effects from potential accidents, irrespective of the cause or location, and to be equally effective whether a submarine is at sea or berthed.
