Abstract
A flowline is connected remotely to an underwater installation, typically an underwater wellhead, by remote operations carried out from an operational base at the water surface by connecting an end of the flowline to a swivel which has a flow passage coaxial with the axis of rotation of the swivel, guiding the swivel downwardly to a predetermined position at the underwater installation, then remotely connecting the swivel passage to a flow passage of the underwater installation, and then laying out the flowline while allowing the swivel to turn freely, whereby the end of the flowline connected to the swivel is allowed to assume a normal installed position which is not dependent upon a predetermined rotational disposition of the swivel.
