Metallic strip flexible pipes (MSFP), a relatively new style of unbonded flexible pipes, are considered as an attractive alternative to traditional submarine pipes. During its reeling operation, it will inevitably confront various complicated loads, which may affect the integrity and safety of MSFP's utilization. In this paper, the tension-extension and moment-curvature relation of MSFP were obtained by laboratorial tests. The mechanical properties were then imported into the global model established in ABAQUS. The finite element model was adopted to predict the deformation and mechanical responses of MSFP during the operation process. Besides, the effects of reeling length, the diameter of the coiling drum, and the pulling force were discussed. The obtained conclusions will provide some references for optimizing MSFP design and preventing possible damage in the reeling operation.

金属带状挠性管（MSFP）是一种相对较新的无粘结挠性管，被认为是传统海底管的诱人替代品。在收卷过程中，它不可避免地要面对各种复杂的负载，这可能会影响MSFP使用的完整性和安全性。本文通过实验室测试获得了MSFP的拉伸-拉伸和弯矩-曲率关系。然后将机械性能导入到ABAQUS中建立的全局模型中。采用有限元模型预测了MSFP在运行过程中的变形和力学响应。此外，还讨论了卷取长度，卷取鼓的直径和拉力的影响。
