The apparatus includes a tower (10) provided with tensioning apparatus (20) which suspends a pipeline being laid into the sea. The tower is mounted on a pivot in order to allow it to be inclined at an angle away from vertical to match the axis of the pipeline being laid. The apparatus also includes a hang-off clamp (22) and abandonment apparatus (36-42) for abandoning the pipeline to the seabed after laying. The abandonment apparatus can be operated independently in order to suspend or lower articles along an abandonment axis (B) which is spaced from the inclined pipeline laying axis (C). Also, the apparatus is capable of aligning the abandonment axis and the hang off clamp with one another while supporting the article. The clamp (22) is tillable into a stowed configuration, in which it is aligned with the longitudinal axis of the vessel. |
