The global Euler buckling loads of marine risers and columns have been presented in an earlier report. In this work we use these results to prove that risers which are in tension along their entire length mav qlobally buckle as Euler columns due to internal static fluid pressure. Numerical examples are used to &1. demonstrate that this phenomenon may occur during normal operating conditions, &2. show the proper distribution of riser supporting forces between top tension and buoyancy, &3. illustrate the effect of boundary conditions on the occurrence of this phenomenon, and &4. study the effect of the riser geometr•c particulars, internal fluid static pressure and total buoyancy on the riser critical length at which buckling in tension may occur due to internal pressure.http://deepblue.lib.umich.edu/bitstream/2027.42/91698/1/Publication_No_246.pd
