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

A connection arrangement 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 connection arrangement comprising:

• a spool piece termination structure comprising a clamping device for clamping together said spool piece hub and pipeline hub, and a base frame openly shaped downwards so as to allow the termination structure to receive a pipeline end section provided with said pipeline hub by lowering the termination structure downwards onto said pipeline end section;
• an alignment structure designed to be connectable to a pipeline end section received in the termination structure by being lowered downwards onto said pipeline end section so as to come to bear against it, the alignment structure being designed to receive, when it is lowered downwards onto said pipeline end section, at least a part of a flange of the pipeline end section, the alignment structure comprising an alignment device for properly aligning said flange and thereby the pipeline hub in relation to the alignment structure when received therein;
• and
• wherein the alignment structure and clamping device are designed to be displaceable in relation to each other when the alignment structure has come to bear against said pipeline end section and the pipeline end section flange has been received in the alignment structure so as to allow the pipeline hub and the spool piece hub to be mutually displaced into contact with each other.
