A support and connecting system for a multiline riser which joins a floating platform to a subsea well is shown including a support housing which mounts upon the floating platform for disconnectably mounting a termination housing to which a plurality of lines are connected. The termination housing is also connected to the platform by a cable tensioning system which adjusts the tension within its connecting cables. A termination head fits within the termination housing and connects, through a termination riser adapter, to the uppermost riser of a riser run that communicates between the platform and the subsea well. The arrangement permits the riser run to engage the floating platform during assembly and recovery of the risers. In the event of a storm or other need for emergency disconnection, the riser run may be withdrawn from the termination housing and hung off or recoved without disconnecting the lines. During production operations, the riser run floats free of the platform connected thereto solely by the multilines and tensioning system. During drilling operations, a telescoping joint connects the termination housing to the support housing.
