摘要：It�s commonly known that there are high collision risks between vessels and jack-ups in work condition. When such an unfortunate incident happens, not only would the jack-up be damaged but also drilling activities might get suspended and economic losses would occur. Comparing with other offshore installations, jack-ups are much more flexible and have a much lower degree of redundancy, but its collision danger has not been paid sufficient attention. As a matter of fact, there is little research on this subject in our country. Based on non-liner finite element analysis methods, taking a 300ft jack-up designed by Shanghai CIMC Offshore R&D Center as an illustrative example, one approach of assessing structural strength for collision between jack-up and vessel considering the initial state of the jack-up and residual strength is put forwarded. Furthermore, the influence of impact parameters on structure damage and dynamic response is considered. The conclusion of this analysis may be helpful to structural design against collision loads for jack-ups.
