ABSTRACT:
A method and apparatus for transporting a marine superstructure on a vessel floating in a body of water to a working site, placing the semi submersible part of the apparatus into a body of water, lowering the semi submersible into a stable position, moving the marine superstructure from the vessel and onto the semi submersible, elevating the semi submersible with the marine superstructure over the marine structure, lowering the semi submersible vessel and the marine superstructure, causing the marine superstructure to rest on the marine structure, pulling the semi submersible away from the marine structure and marine superstructure and placing the semi submersible back onto the vessel. To remove the marine superstructure from the marine structure and place the marine superstructure onto the vessel the same method is used in reverse.
