When spooling a pipeline on a reel in reality (Figure 5.1),the beginning of the pipeline is
attached and fixed to the reel.The pipeline is then bent on the reel by paying out pipeline
through the tensioners which jointly with the driving moment of the reel keep the pipeline
under tension.The pipeline is positioned on the drum in several layers.
Figure 5.1 Spooling pipeline on the reeling vessel “Deep Blue”
78 Chapter 5
The bending moment in the pipeline increases from the tensioners to the reel (Figure
5.2).On the reel the bending moment changes only when the radius changes,e.g.when
the pipeline is reeled as a next layer on the drum.No change in bending moment within
one layer of pipeline means that the shear force is zero within this layer.
The first layer of pipeline is the most critical,because in this layer the pipeline
experiences the largest curvature.
Figure 5.2 Moment and shear force diagram of the pipeline during spooling-on in the
actual reeling process (excluding the weight of the pipe)
Because there is no shear force in the pipe that is in contact with the reel,the
perpendicular force in the tensioners,FT;P in Figure 5.3,needs to be in equilibrium with
the reaction force of the reel on the pipe,Freel;T;P in Figure 5.3.Figure 5.3 is valid for a
horizontal reel (i.e.Global Industries “Chicasaw” [7]).When the reel is positioned
vertically (i.e.Technip “Deep Blue” [5],[28],[59]),the perpendicular force in the
tensioners (FT;P) plus the weight of the pipeline,are in equilibrium with the reaction force
of the reel on the pipeline (Freel;T;P).
