A GTS-Based Reliability Analysis Method for the Subsea Gas Boosting System

A subsea gas boosting system is a complex system with a variety of components and multiple working states, resulting in the difficulty in modeling. A new method based on guarded transition system (GTS) is proposed in this paper, to analyze the reliability of the subsea gas boosting system. First, by analyzing the structure and function of the system and classifying the components, the model is built to depict system. Then, the operation modes and phases of the system were analyzed to establish the state transition chart accurately. On this base, the GTS model of the system with three operations modes was established to get the steady-state reliability indexes of the system. The GTS-based model is constructed from the subsea gas boosting structure, it is more suitable to establish the virtual operating mode.
