<p>Disclosed herein is a guide frame (10) for location at one or more points along the length of a riser tower structure (112,114). The riser tower structure is of a type that has an upper end supported at a depth below the sea surface and has a central core (200) with one or more conduits (220) arranged therearound extending from the seabed toward the surface. In use, the guide frame guides the conduit (s) relative to the central core, said guide frame (10) being attachable to said riser tower structure non-continuously (40,50), thereby not becoming an integral part of said riser tower structure. Also disclosed is a riser tower comprising such guide frames.</p> |
