Spool piece termination structure, a connection arrangement comprising such a termination structure and a pipeline termination

A method for subsea connection of a pipeline to a spool piece by clamping together a pipeline hub secured to an end section of the pipeline and a spool piece hub secured to an end section of the spool piece, the method comprising:

• a spool piece termination structure, to which the spool piece hub is mounted and which comprises a clamping device, is made to receive the pipeline end section and the associated pipeline hub by lowering the termination structure downwards onto said pipeline end section,
• the pipeline hub and the clamping device are displaced towards each other so as to bring the pipeline hub and the spool piece hub with the clamping device into contact with each other,
• whereupon the clamping device is activated so as to clamp together the pipeline hub and the spool piece hub.

A pipeline termination to be applied to the end section of a pipeline so as to allow the pipeline to be connected sub-sea to a spool piece, the pipeline termination comprising:

• a pipeline hub designed for connection to a corresponding spool piece hub, and
• a flange located behind the pipeline hub and designed to constitute a reaction shoulder for use in the alignment and displacement of the pipeline termination and the associated pipeline hub in relation to said spool piece hub.
