摘要：Risers work in complex and harsh environments, in addition to normal work load, environment loads, also threatened by accidental loads, such as the impact of ships. It is essential to analyze and assess the behaviors of riser subjected to the accidental loading. The work presented in this paper focus on the risk of pipe-in-pipe riser subjected to vessel impact. Threedimensional finite element method is employed to simulate the structural response and structural damage. On the basis of research on the risk analysis method and structural collision damage, risk quantitative assessment system of pipe-in-pipe riser collision is built to achieve the risk assessment from the traditional experience to scientific prediction type. ? 2011 IEEE.
