Abstract: A pipe structure suitable for being laid in the sea comprises an inner pipe (2) for conveying fluid to be transported along the pipe structure and an outer pipe (3) around the inner pipe and supporting the inner pipe with space between the inner and outer pipes, the outer pipe having openings to allow water first to flow into the space between the inner pipe and the outer pipe and then to flow out of the space.

Abstract: A method of removing a deck from an offshore structure is provided. An apparatus for carrying out the method is also described.

Abstract: A method of removing a deck from an offshore structure (11) including a deck (13) supported on a jacket (12), includes the following steps: a) positioning a floating vessel (10) around the jacket with respective parts of the vessel on opposite sides of the jacket (12) and trusses (3, 4) extending between the opposite parts of the vessel, b) engaging parts of the trusses (3, 4) with legs (15) of the jacket, c) securing the trusses (3, 4) to the jacket (12), d) relieving the load carried by portions of the legs (15) of the jacket (12), e) cutting through the portions of the legs (15) of the jacket to divide the jacket into a lower part and an upper part carrying the deck, the trusses (3, 4) being secured to the upper part of the jacket (12), f) transferring the weight of the upper part of the jacket (12) and of the deck (13) via the trusses (3, 4) to the floating vessel (10), and g) removing the floating vessel (10), with the trusses (3, 4), the upper part of the jacket (12) and the deck (13) supported thereon,

Abstract: Photocopy machine having a feed module for successively feeding individual original documents from a stack thereof. Cooperating portions of the feed module and of the photocopying machine form a straight line original document feed path having an entryway that is accessible for conventional insertion of original documents. The feed module includes apparatus for successively feeding original documents from a stack along a direction reversing path that leads to the above entryway of the straight line feed path. The feed module can be pivoted to afford access to the straight line original document path and to permit copying of original documents which cannot be sheet fed. The feed module includes an original document separating arrangement wherein a feed tire and flanking retarder bars are cooperatively disposed so as to obviate need for any adjustment of the arrangement to afford proper feeding of documents of variable thickness.
