    Abstract: This invention relates to a method of positioning an end (210) of a pipeline (200) on a subsea structure (300). The method comprises the steps of: (a) providing a channel (305) on the subsea structure, the channel having an open end adjacent to a receptacle (335) on the subsea structure, (b) providing a pipeline, (c) attaching a connector (325) to an end of the pipeline, (d) laying the end of the pipeline with the connector attached into the channel, and (e) pulling the pipeline end along the channel such that the connector exits the open end of the channel and is received by the receptacle. The invention also relates to a channel for use in the method and a subsea structure wherein the channel is provided on the upper surface of the subsea structure.
