ABSTRACT:
A method is disclosed for installing an integrated deck on a platform substructure located in a body of water. The deck is supported on jack-up means which, in turn, are mounted on a rigid pontoon raft having a U-shaped configuration. The jack-up means is capable of raising and lowering the deck to and from, respectively, the substructure and for raising the composite platform from one position and lowering it to another position offshore. The U-shaped opening in the raft is oriented so that the jack-up means on the barge straddles the substructure below the deck. Piles may be driven through the base from the raft and from the platform itself when the raft has been removed from the deck once the deck has been installed on the substructure.
