For the purposes of section 120 of the Act (employment at sea (continental shelf operations))83, prescribed employment shall be any employment (whether under a contract of service or not) in any area which may from time to time be designated by Order in Council under section 1(7) of the Continental Shelf Act 196484, where the employment is in connection with any activity mentioned in section 11(2) of the Petroleum Act 199885 in the designated area.

Where a person is employed in any employment specified in paragraph (1), the provisions of Part I of the Act and so much of Part VI of the Act as relates to contributions shall, subject to the provisions of paragraph (3), apply as though the area so designated were in Great Britain, and notwithstanding that he does not satisfy the conditions as of residence or presence in Great Britain prescribed in regulation 145(1)(a).

Where a person employed in any employment specified in paragraph (1) is, on account of his being outside Great Britain by reason of that employment, unable to perform any act required to be done either immediately or on the happening of a certain event or within a specified time, he shall be deemed to have complied with the requirement if he performs the act as soon as reasonably practicable, although after the happening of the event or the expiration of the specified time.
