1.In exceptional circumstances, which shall be duly justified to the flag State administration, when marine equipment needs to be replaced in a port outside the Union where it is not practicable in terms of reasonable time, delay and cost to place on board equipment which bears the wheel mark, other marine equipment may be placed on board subject to paragraphs 2 to 4.
2.The marine equipment placed on board shall be accompanied by documentation issued by a Member State of the IMO which is a party to the relevant conventions, certifying compliance with the relevant IMO requirements.
3.The flag State administration shall be informed at once of the nature and characteristics of such other marine equipment.
4.The flag State administration shall, at the earliest opportunity, ensure that the marine equipment referred to in paragraph 1, along with its testing documentation, complies with the relevant requirements of the international instruments and of this Directive.
5.Where it has been demonstrated that specific marine equipment bearing the wheel mark is not available on the market, the flag Member State may authorise other marine equipment to be placed on board, subject to paragraphs 6 to 8.
6.The authorised marine equipment shall comply, as much as possible, with the requirements and testing standards referred to in Article 4.
7.The marine equipment placed on board shall be accompanied by an interim certificate of approval issued by the flag Member State or by another Member State, stating the following:
(a)the equipment bearing the wheel mark which the certified equipment is due to replace;
(b)the exact circumstances under which the certificate of approval has been issued, and in particular the unavailability in the market of equipment bearing the wheel mark;
(c)the exact design, construction and performance requirements against which the equipment has been approved by the certifying Member State;
(d)the testing standards applied, if any, in the relevant approval procedures.
8.The Member State issuing an interim certificate of approval shall inform the Commission forthwith. If the Commission considers that the conditions of paragraphs 6 and 7 have not been met, it may require that Member State to revoke that certificate or take other appropriate measures by means of implementing acts. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 38(2).
