Structural Integrity of Offshore Pipelines
Sponsor:
Offshore Technology Research Center (OTRC) - Texas, USA
Partners:
The University of Texas at Austin, USA
Texas A&M University, USA
Objective:
The research aimed at investigating the structural capacity of underwater steel pipelines against buckling. A nonlinear finite element technique is developed (source code) for the nonlinear analysis of pipe segments under bending, pressure and axial load.
