ABSTRACT:
A method and apparatus for transferring a functional package from a jack-up rig to a fixed platform is provided. A functional package comprising a drilling package, a construction crane, a rocket launch module, or other heavy apparatus may be directly placed upon a fixed platform without exceeding the load bearing limits of a fixed platform. This placement occurs using a cantilever beam that is spliced so that it may be separated into a shuttle portion and a base portion to reduce the weight effect of the cantilever beam upon the fixed platform. The cantilever beam may be provided with a new and unique splice section that permits detachment of the distal shuttle portion upon which rests a functional package. The distal shuttle may be deposited onto a fixed platform. The distal shuttle may be reattached after operations are completed for transfer of the functional package to another location.
