Apparatus for overboarding an article from a pipe laying vessel includes a pipe laying tower (10) that is mounted above a tower supporting platform. The tower has tensioners (20) for suspending a pipeline (34) being laid from the pipelaying vessel into the sea and adjusters for adjusting inclination of the tower to align the tensioners with a departure axis of a pipeline being laid. A hoist (26, 27, 32) allows large articles (25) to be suspended from the tower. Adjusters (16) allow the tower to be angled beyond the departure axis, such that the hoist suspends the article outboard of the platform. Articles too large to pass the tower supporting platform of the vessel can be maneuvered first outboard of the tower supporting platform, then lowered and brought beneath the tower supporting platform back into line with the departure axis for connection to the pipeline. A method of laying pipe line from a vessel is also provided.
