Abstract
Strain has a high sensitivity to structural damage and can be used for damage diagnosis of marine risers in engineering. Considering the structure and boundary conditions of the top tensioned riser, it can be simplified to the Euler-Bernoulli beam element, and the strain equation on the riser wall is derived. The element Root-Mean-Squared Strain(RMSS) difference is proposed as the damage index parameter of the riser. The finite element software ANSYS is used to simulate the element strain response of the 1000m length top tensioned riser in the South China Sea with different damage locations, damage degree and sea state parameters, and the RMSS difference curve is drawn. The results show that the RMSS difference has high sensitivity to the riser structure damage, and the damage position of the riser can be effectively identified in many different situations.
