The problem of definition of lift capability and supercritical behaviour of a thich-walled pipe are considered in view of inhomogeneous elasticoplastic properties in the field of a seam and residual technological pressure under an operation of internal and external pressure, bending of a pipe and locally disrtibuted effort, on a surface. The effects are assumed varying in time simulating loading of a pipe at immersing on bottom of the sea and while in service. The special attention is given to the shapes confortion of a pipe at subcritical and supercritical deformation, almost up to full confortion.
