Abstract

This paper analyzes the fatigue monitoring parameter selection and long-distance wireless transmission in deep water drilling riser fatigue monitoring technologies, and designs a deep-sea riser fatigue monitoring system based on MCU+DDS structure. This monitoring system can monitor riser Vortex induced vibration, riser stress and strain and current velocity of seawater in real time. This system can also process and compress collected data, and then transmit modulated data to surface via underwater acoustic channel. The prototype of monitoring system was tested, it is practicable and reliable.
