Risk analysis of collisions during FPSO offloading operations

Collisions are studied as the main risks of floating production, storage and offloading (FPSO) offloading operations in this paper. The large application of FPSO in offshore industry has highlighted the safety issues during offloading operation. Firstly, the research progress about offshore collisions and the related risk analysis methods are studied. Secondly, a compact analysis of collisions and near miss cases is done in order to identify the risk factors associated with the collisions. The results are illustrated using fault tree analysis method. Finally, qualitative analyses of collisions are discussed regarding excessive surge and horizontal oscillation based on the feature of FPSO operations in China seas. The status of FPSO with diverse relative positions is studied and the corresponding risk control measures are presented. The works herein are instructive for the operation process during FPSO offloading.
