SUBSTRUCTURE FOR OFFSHORE PLATFORM

摘要

The invention provides a substructure (111) to form part of a fixed offshore platform, the substructure having at least one foundation element (116) adapted to rest in or on the seabed (117), a structural component (112) configured to extend upwards from the foundation element (116), provision for at least one conductor (121) to extend downwardly from the structural component (112) into the seabed (117), and provision for means (122) to apply tension to the conductor (121), so to increase the bearing (compressive) load of the foundation element (116) on the seabed (117) to resist any uplift (tensile) load arising from overturning moments which might otherwise tend to cause that foundation element (117) to lift off the seabed.
