The Audio Monitoring System is a specialized component in hydraulic decoking systems, designed to provide real-time acoustic feedback during coke cutting and boring operations in delayed coking units (DCUs). This system helps operators detect key process sounds such as tool contact, cutting performance, blockages, or free-fall conditions, which may not be visible through standard video monitoring alone.

Installed near the cutting deck or coke drum, the system includes high-sensitivity industrial microphones with noise-canceling and filtering features, ensuring clear, actionable audio in high-noise refinery environments. The system can be integrated with decoking control panels or remote operation consoles, enabling enhanced situational awareness, safety, and predictive maintenance. By capturing subtle changes in sound signatures, the Audio Monitoring System supports faster operator response, reduced risk of tool damage, and more efficient decoking cycles.
