The deep-sea drilling vessel "CHIKYU" is a riser-equipped, dynamically positioned scientific drill ship owned and operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and built for the purpose of scientific research and exploratory expeditions. Advanced measurement-while-drilling (MWD) technology transmits real-time data from the downhole to the upper surface of the vessel using a pressure wave, i.e., a mud pulse, generated with a pressure modulator through the drill string. In this study, testing equipment for return pressure wave propagation has been developed and performance tests have been carried out to generate return pressure waves from a pressure modulator located within the drill pipe to monitor mud pulse data transmission.
