Claims16
A method for transporting and installing, in a body of water, a jack-up rig, having a hull and a plurality of jack-up legs, comprising the steps of:
- (a) associating a submersible production storage barge, having an upper wall surface, with the hull of the jack-up rig;
- (b) passing the plurality of jack-up legs through openings formed in the submersible production storage barge and releasably securing the submersible production storage barge to the jack-up rig;
- (c) moving the jack-up rig and submersible production storage barge to a desired site in the body of water, the jack-up rig being disposed above the upper wall surface of the submersible production storage barge while the jack-up rig and the submersible production storage barge are being moved;
- and
- (d) lowering the plurality of jack-up legs and the submersible production storage barge until they rest upon a surface below the body of water.
