ABSTRACT:
A method and an installation for connecting a rigid submarine pipe and a flexible submarine pipe. The rigid pipe terminates in a free connection end. The flexible pipe has a flow-line portion and a suspended portion. The flow-line portion has an input end connected to the free connection end. The installation comprises an anchoring device to hold the flow-line portion anchored at an anchor point and to allow the flow-line portion to form an undulation. The anchoring device is suitable for holding the anchor point at a distance and close to the free connection end to form the undulation between the anchor point and the free connection end.
