The coupling response between the top joint and flexible riser is examined in terms of the coincidence of the dominant vibration frequency, which is closely related to the spatial mode competition, presenting the time-varying response profile and vibration frequency as well as the spatial evolution of dominant frequency and modal weight. It is installed in systems where monitoring pressures are required. Despite their variety, the vibration phenomena from many different engineering fields can be classified into a relatively few basic excitation mechanisms. High-frequency piping vibrations are called acoustic-induced vibration (AIV), because the flow is mostly gas and the vibrations typically produce sound waves within the range of human hearing.
