METHOD AND APPARATUS FOR TRANSPORTING AND USING A DRILLING OR CRANE APPARATUS FROM A MOVABLE VESSEL

摘要

A method and apparatus for transporting and using a drilling apparatus (10) or a construction crane apparatus (308) from a single movable vessel is pro- vided. Either a drilling apparatus or a construction crane apparatus is skidded on- to the deck of a jack-up rig (12) which is then floated to a remote location for use of the apparatus. The skidding of the construction crane apparatus is facilitated by a new and unique pony structure (304) to raise the base of the constructi on crane apparatus above a skid on the jack-up rig (12).
