Abstract
A method for connecting a subsea wellhead to a subsea manifold by an articulated flowline comprised of a plurality of flowline segments joined in series by adjustable ball joint connectors each of which comprises a plurality of bolts for clamping the joined segments in a fixed position and means for stretching the bolts by applying a force which does not exceed the yield strength of the bolts to loosen the connection. The method includes attaching one end of the flowline to an outlet of the wellhead, adjusting each of the ball joint connectors to configure the flowline as necessary for attaching the other end of the flowline to the manifold, and attaching said other end of the flowline to the manifold.
