Abstract
Assessment of the subsea steel indented pipelines, has been the subject of considerable study over the last years. In this research, a parametric study has been conducted to evaluate the effect of indentation on the induced residual stresses. An equation to predict the value of the residual stress has been formulated based on the parametric study. This equation has taken into consideration the main controlling parameters with good agreement with the experimental results. In addition and in order to give a full assessment for the dented pipeline,Three cases of study have been performed on real sea storm waves and soil conditions at the Arabian Gulf region (United Arab Emirates) to evaluate the fatigue lifetime considering the dent effect
