Significant bending occurs near the barge and near the seabed.
Fig. 2: S-lay installation and pipe deformation for (a) Bend radius = 30 m, (b) Bend radius = 10.71 m, and (c) Bend radius = 10.3 m.
Note that incipient local “kinking” (short-axial-wavelength post-bifurcation buckling)
is especially visible in (c).
