This study extends the analysis of a compliant buoy-ballast system integrated into a tethered ROV/USV setup, enhanced with IMU sensors, employing a comprehensive simulation framework for cable dynamics. Building on previous work, this research explores the use of IMU-based measurements to detect risk-prone configurations during ROV operations, specifically focusing on the creation of cable lobes. The study introduces a lobe detection indicator, which compares the signs of horizontal angles obtained from relevant IMUs placed on the cable to identify these configurations. The relevance of this metric was assessed in simulations involving various types of turns during a ROV mission. The results demonstrate that the proposed metric is effective in detecting undesirable lobe formations, and integrating this detection into the winch control system can potentially improve the overall reliability of the ROV/USV system.
