Abstract
The present subject matter provides a three-rail multi-direction direct cantilever skidding system suitable for an offshore drilling system, where the three-rail multi-direction direct cantilever skidding system comprises movable guides accommodating the cantilever of a Jackup drilling unit and enabling transverse skidding rails to provide direct support for the cantilever so the cantilever may be moved in both longitudinal and transverse directions.
