Underwater information processing platform is the nerve center of the riser fatigue monitoring device. It controls fatigue parameters detection, signal processing, data transmission, dormancy and initiation of the monitoring equipment and a series of processes. The hardware system of the low-power-consumption underwater information processing platform consists of low-power microprocessor, high-speed digital signal processor (DSP), a variety of sensors, signal modulation and transmission circuit, power supply and other accessories and so on. In order to improve the service period of the monitoring equipment, we optimize the design of the low-power underwater information processing platform during the "Eleventh Five-Year" period. We add storage modules and optimize spatial layout and program flow to greatly reduce the circuit board area. After optimization, the reliability of the underwater information processing platform is enhanced further. And then the volume and weight of the riser monitoring system are reduced and its convenience and applicability are improved.

Key words: marine oil and gas pipeline, deepwater riser, fatigue, low power consumption, underwater information processing platform, optimal design
