A three-dimensional analysis for pipelines suspended between the ocean floor and a lay barge or stinger can account for not only the variations in bending stiffness, weight, buoyancy, crosscurrent, and lateral bay drift but also the effects of external hydrostatic pressure and buckling of the pipes. The total Lagrangian geometrically nonlinear analysis uses a special element for oriented bodies in space, making the technique quite versatile.

Abstract
A three-dimensional analysis for pipelines suspended between the ocean floor and a lay barge or stinger can account for not only the variations in bending stiffness, weight, buoyancy, crosscurrent, and lateral bay drift but also the effects of external hydrostatic pressure and buckling of the pipes. The total Lagrangian geometrically nonlinear analysis uses a special element for oriented bodies in space, making the technique quite versatile.
