This research conducted for overcoming the high non-productive time (NPT) damage of fluid end part mud pump in the drilling of PT. Pertamina PDSI Drilling Rig # 42.2/N1500-E Well SWI-001 at Pali, South Sumatra, Indonesia. The purpose of this study is to provide a solution for detecting early worn out of fluid end part with the innovation of the electric audio module (EAM), which is suitable for conditions in the field. This EAM works using the method of detecting acoustic emission signals from piezoelectric sensors that arise due to the movement of the drilling fluid and fluid end part in the mud pump module body. Then the emitted pulse is forwarded to the EAM, and the results give through two outputs, namely the spectrogram graphic and the acoustic emission sound that enlarged through headphones. The results of this EAM innovation can reduce the NPT in PDSI Rig # 42.3/N1500-E from 34.5 hours to 0 hours, and monitoring can be done remotely up to more than 50 meters no longer on the spot. The application of EAM in drilling rig implies a modification in the maintenance of a mud pump from breakdown to predictive maintenance. It supports the safety aspect considering monitoring which can perform remotely.
