Article 13 5.

Where Member States consider that the management of a human activity at Community or international level is likely to have a significant impact on the marine environment, particularly in the areas addressed in paragraph 4, they shall, individually or jointly, address the competent authority or international organisation concerned with a view to the consideration and possible adoption of measures that may be necessary in order to achieve the objectives of this Directive, so as to enable the integrity, structure and functioning of ecosystems to be maintained or, where appropriate, restored.
