1. This notice gives details of the arrangements for the creation of offshore development areas (ODAs).
2. Offshore development areas were introduced in 1980 as a means of advising mariners not to enter particular areas because of the high levels of activity associated with the establishment of offshore installations. HSE acts as a link between operators, consultees and the Hydrographic Office.
4. Application to establish an offshore development area may be made to HSE who will act as the link between interested parties. After consultation ODAs will be marked on Admiralty charts, and a Notice to Mariners issued by the Hydrographer.
5. If operators feel specific markings are necessary for circumstances other than in paragraph 3, they should apply to the Hydrographic Office to have a revised warning note included on Admiralty charts for the information of all mariners including fishermen.
6. In all cases, the Hydrographic Office has advised that they must be provided with full details of all activities/installations so that a decision can be made on the most appropriate way in which this information is distributed, to ensure the safety of all categories of mariners. Any such action would be entirely a matter for operators and mariners, and would not involve HSE.
7. The Hydrographic Office is situated at:Hydrographic Office
8. Any queries relating to this notice should be addressed to:Health and Safety Executive
