A method and system for continuously joining and deploying pipe from a moving vessel is disclosed. The method comprises the steps of (a) providing an S-lay system comprising a guiding system mounted on a vessel; and a joining system moveable along the guiding system in a direction substantially corresponding to the firing line of a pipe string; (b) providing an additional pipe section to be joined to an end of a deployed pipe string; (c) actuating the joining system to hold an end of the deployed pipe string and the additional pipe string; and (d) as the vessel moves in a laying direction: moving the joining system along the guiding system in a direction opposite to the laying direction; operating the joining system to join the additional pipe section to the deployed pipe string to form an extended pipe string as the joining system moves; and deploying the extended pipe string from the vessel.
