ABSTRACT:
A system for starting up a flowline suitable for conveying hydrocarbons is provided. The flowline is extended over the seabed from a wellhead and terminated at a joint end. The joint end is suitable for connection to a subsea riser extended in a catenary. The flowline is able to stretch and a lock fixes the joint end with respect to the seabed for maintaining the flowline in its stretched position, and preventing its return movement.
