Strength design of marine risers under the action of external loads, internal pressure and thermal expansion

Abstract

The article deals with new scientific results and methods of calculating the strength of marine risers by the
action of external loads, internal pressure and thermal expansion. To optimize the calculation, and obtain the most
accurate results, a computer program Bentley AutoPIPE XM Edition, which has the necessary certification and is
based on the finite element method was used. As a result of the calculations we can determine the optimal thickness
of the pipe and select the material and take the necessary measures to prevent critical loads. For areas where there
is a probability of ice fields the method is efficiently used for risies installation when they are not subjected to ice
loads (laying them inside casings or supporting columns of platforms).
