Pipe (3) to be laid on the seabed from a floating pipe laying vessel (1) emerges from the bottom end of a vertically orientated linear pipe tensioner (8b) and is directed substantially vertically downwardly to pass through a surrounding pipe guide (12), which causes the pipe to deviate from the vertical through a small acute angle (theta). In this way, the horizontal thrust that would be exerted on the pipe tensioner (8b) due to the tension in the pipe if the tensioner were to be the last guide means for the pipe before it enters the sea is transferred to the pipe guide itself, this being mounted in the vessel at a location of greater structural strength. |
