The full scale bending rig in the laboratory and thus
the small scale bending rig in the laboratory as preparation,both bent pipes in the
horizontal plane.Therefore,Figure 5.2 and Figure 5.3 are applicable to these bending
rigs.In the horizontal spooling-on process onboard of the reeling vessel the pipeline is
supported between the reel and the tensioners.In the full scale bending rig the pipe was
supported by rollers.In Figure 5.3 the equilibrium of the forces on the pipeline comprises
two parts.In the first part the perpendicular force in the tensioners (FT;P) is in equilibrium
with the reaction force of the reel laterally to the pipeline (Freel;T;P).In the second part the
tension force (FT;A) is in equilibrium with the distributed load of the reel on the pipe (qreel).
It should be noted that the reaction force of the reel on the pipeline (Freel;T;P) is in fact a

distributed load.However,for reasons of simplicity,this distributed load is treated as a
concentrated load.In Figure 5.3 the axial friction between the reel and the pipeline is not
taken into account for reasons of simplicity as well,because the stresses due to the axial
load on the pipeline are negligible compared to the bending moment and the shear force
applied on the pipeline.
Figure 5.3 Forces on the pipeline during spooling-on in the actual reeling process
During spooling-on of the pipeline,the distance between the tensioners and the reel can
vary for different reeling vessels but remains constant during the spooling-on process.
The tension force is normally kept constant during the reeling process.However,it is
possible to increase the tension force during the reeling process,which may be required
in order to prevent local buckling [11],[6].

However,for reasons of simplicity,this distributed load is treated as a concentrated load.
但,为方便起见,我们视分布式荷载为一个集中式荷载.
In Figure 5.3 the axial friction between the reel and the pipeline is not taken into account for reasons of simplicity as well,because the stresses due to the axial load on the pipeline are negligible compared to the bending moment and the shear force applied on the pipeline.
在图5.3中卷轴与管道间的轴向摩擦也做了近似处理,因为相对于弯矩和剪切力在官道上的作用,轴向荷载对管道的作用力可忽略不计.
