This Act shall apply to any activity mentioned in subsection (2) below which is carried on from, by means of or on an installation which is maintained in the water, or on the foreshore or other land intermittently covered with water, and is not connected with dry land by a permanent structure providing access at all times and for all purposes.

but, subject to paragraph (b) above, does not include any part of a pipe-line within the meaning of that section ;
- “modfications” includes additions, omissions and alterations.
6
The fact that an installation has been maintained for the carrying on of an activity falling within subsection (2) above shall be disregarded for the purposes of this section if, since it was so maintained, the installation—
a
has been outside controlled waters or, where it was so maintained in a part of a foreign sector of the continental shelf adjacent to those waters, the area consisting of those waters and that part ; or
b
has been maintained for the carrying on of an activity not falling within that subsection.
7
Orders in Council made under this section may be varied or revoked by a subsequent Order so made ; and any statutory instrument containing an Order under subsection (3) above shall be subject to annulment in pursuance of a resolution of either House of Parliament.
