Abstract
A method and apparatus for transporting and using a drilling apparatus or a construction crane apparatus from a single moveable vessel is provided. Either a drilling apparatus or a construction crane apparatus is skidded onto the deck of a jack-up rig 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 to raise the base of the construction crane apparatus above a skid on the jack-up rig.
