Abstract

The collision between serial risers was studied using the restart analysis of finite element software ABAQUS to consider the coupling effect between the water and risers.In the study,the results of the static bending analysis were input into the dynamic analysis.The collision behavior between adjacent risers was analyzed under the situations with and without considering the riser-water coupling effect and the influences of single factors,such as the velocity,angle,and internal pressure were discussed.The stress responses in the collision process of adjacent risers were obtained.The results show that multiple times of collisions may happen between two serial risers under the given cases,and the stresses with considering the riser-water coupling are smaller than those without considering the coupling.The effects of impact velocity,angles and internal pressure on the stresses are different under the situations with and without considering the coupling.The stresses induced by the first collision increase with the increase of impact velocity.The results show that risers are safer when they are subjected to a certain internal pressure compared to bare risers.When the impact angle is 45 degree,the maximum stress is lower.Therefore,there are proper values of angle and internal pressure for the riser’s safety.The results provide a reference to the arrangement of risers group to avoid collision damage.
