At the end of Phase I (Figure 5.9),when the plastic bending moment was reached at the initial contact point,the reaction force of the reel on the pipe (Freel) still equalled the hydraulic cylinder force (FHC) plus the lateral fixation point force (FFP;P).In Phase II (Figure 5.9) the reaction force from the reel on the pipe (Freel) was divided in two components:one (Freel;FP) was in equilibrium with the lateral fixation point force (FFP;P) and the other (Freel;HC;y) was in equilibrium with the y-component of the hydraulic cylinder force (FHC;y).For the pipe section in contact with the reel,there was no change in bending moment as the curvature was determined by reel size.Because there was no change in bending moment,there was also no shear force.Therefore the y-component of the hydraulic cylinder and the fixation point force needed to be in equilibrium with the reaction forces Freel;HC;y and Freel;FP,respectively.This equilibrium was also met during actual reeling.
Figure 5.9 Phases I and II in the reeling simulation tests:(ICP = initial contact point)
In Phase II of the reeling simulation test the equilibrium of the forces on the pipe comprised two parts (Figure 5.10).In the first part,the perpendicular component of the hydraulic cylinder force (FHC;P) was in equilibrium with the reaction force of the reel acting laterally on the pipe (Freel;HC;P).The lateral fixation point force (FFP;P) was in equilibrium with the reaction force of the reel on the pipe at the fixation force side of the reel (Freel;FP).
In the second part,the axial component of the hydraulic cylinder force (FHC;A) was in equilibrium with the distributed load of the reel on the pipe (qreel) and the axial force at the fixation point (FFP;A).The axial friction between the pipe and the reel was disregarded for reasons of simplicity.
