PIPE-LAYING VESSEL AND METHOD OF LAYING A PIPELINE

摘要

A pipe-laying vessel (100) including a pipe-laying tower (300) extending upwardly from the vessel, the tower comprising a first lower section (310) extending upwardly from a proximal end to a distal end above the main deck (103) of the vessel, and a second upper section (311) movably mounted on the first lower section, and the tower having a first pipe-laying configuration for laying pipeline P in which the second upper section (311) is positioned above the lower section (310) and pipe is passed from the second upper section (311) to the lower section (310) when, in use, it is being laid, and a second stowed configuration in which the second upper section (311) is moved relative to the lower section (310) and the overall height of the tower (300) is reduced.
