Abstract

A transporter (1) for removal of an offshore platform topsides (16) from an associated jacket (17), comprises an oblong, ballastable structure (1) with a U-shaped cross section and a prismatic enveloping surface, consisting of two long sides (2), an intermediate underside (3) and an opposite open upper side. At one end the underside (3) has a recess (11) which can hold the jacket (17) when the transporter (1) is located with the underside horizontally down in the sea (18), and on the side of the recess (11) the long sides (2) have contact sections (63) which, when the transporter is deballasted, can be brought into abutment against the platform topsides (16) and lift it, thus transferring it to the transporter. A barge (75) can then be moved in under the topsides (16), whereupon the transporter (1) is ballasted, with the result that the topsides (16) is lowered on to the barge (75) and transferred thereto. In areas under the contact sections (63) the long sides (2) are provided with guide rails (77) for attachment to slide blocks (81) on the barge (75), which guide rails (77) extend in the direction perpendicular to the underside.
