Abstract
An offshore construction system comprises a work module support vessel having a ballast-down mode, in which a deck of the vessel is submerged below the water surface, and a ballast-up mode, in which the deck is disposed above the water surface. The system further comprises an independently floatable, pontoon-supported work module carried on the deck of the support vessel. The system also includes a draw connected between the work module and the work module support vessel. The draw has a draw-over mode, in which the work module is drawn over the deck of the support vessel, and a remove mode, in which the work module is removed from the deck.
