A spool piece termination structure to be mounted to a spool piece so as to support a spool piece hub during the connection of the spool piece hub to a corresponding pipeline hub. The termination structure includes a clamping device for clamping together the 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 the pipeline hub by lowering the termination structure downwards onto the pipeline end section. A connection arrangement includes such a spool piece termination structure and a method for subsea connection of a pipeline to a spool piece.
