  • Semisubmersible vessel for transporting and installing heavy deck sections offshore using quick drop ballast system
    Patent number: 5403124
    Abstract: A method and apparatus for transporting and installing a deck of an offshore platform onto a substructure without requiring heavy lift cranes. The towing vessel or semisubmersible vessel is configured with a cutout or opening therein that surrounds the substructure onto which the platform is to be placed. The platform is transported in an elevated position upon the semisubmersible vessel and it spans across this opening such that once the semisubmersible vessel is properly positioned (i.e. the elevated platform being positioned over and in alignment with the substructure), the semisubmersible vessel is rapidly ballasted thereby transferring the platform onto the substructure.
