Abstract

A method serves to mount the piles (6) associated with the installation of a pile-founded offshore platform, e,g, a production platform, wherein these are driven down into the sea bed through pile guides (12) attached to or forming part of the foundation (16) of the platform. A device for performing the method comprises at least one chute (15) which is preferably C- or U-shaped in cross section and which extends with a suitable inclination upwardly from the upper end (13) of a pile guide (12) to at any rate substantially in below the position which the pile tip (8) of a pile (6) to be placed in the pile guide (12) assumes in said freely hanging position of the pile (6). A conventional drilling rig may be used for installation of in particular smaller platforms, thus providing great savings in terms of economy and frequently also in terms of time.
