Abstract

Offshore structure carrying a plurality of curved conductor casings, which structure is situated on the bottom of a body of water and supports a platform 6 at a level above the said body of water, each conductor casing comprising a curved part 12 and a non-curved part 13, the non-curved part being inclined to the vertical and extending from a level below the seabottom to a level between the seabottom and the platform, and the curved part consisting of a pre-curved tubular element that is connected to the top of the non-curved part and has the central axis of the top opening thereof substantially vertically arranged. A method of installing a curved conductor casing on an off-shore structure supporting a platform is disclosed. <IMAGE>
