Numerical Investigation and Design of an Acoustic Communication System for a Deep-Sea Autonomous Underwater Vehicle (AUV) in Oil and Gas Applications

Autonomous Underwater Vehicles (AUVS) operating at extreme depths face substantial challenges in maintaining reliable data communication due to high pressure, strong absorption, and environmental noise. This study presents a numerical analysis and system-level design of an acoustic communication framework for a deep-sea AUV operating at ۶۰۰۰ meters. Transmission Loss (TL), Received Power (Pr), and Signal-to-Noise Ratio (SNR) are evaluated across frequencies from ۵-۳۰ kHz and communication ranges up to ۱۰ km. Results indicate that low-frequency signals (۵-۱۰ kHz) enable significantly longer communication distances due to reduced absorption. Practical implementation considerations including transducers, hydrophones, and signal-conditioning are also discussed to support real-world deployment. Unlike many existing studies that focus on shallow or mid-depth underwater communication, this work specifically addresses acoustic system design constraints for ultra-deep operations at depths up to ۶۰۰۰ meters in offshore oil and gas environments. Findings offer quantitative and practical guidelines for selecting acoustic frequencies and designing robust communication systems for deep-sea AUV missions.
