Underwater communication systems are essential for divers, submersibles, or remotely operated vehicles (ROVs) to communicate with surface personnel. Proper installation and maintenance ensure the system provides clear, uninterrupted communication at depths. Service tasks include testing signal clarity, checking the integrity of the cables and transducers, and ensuring the system can withstand underwater conditions. Regular maintenance ensures optimal performance, allowing crew and divers to communicate effectively, especially during critical operations, and ensuring compliance with marine safety standards.
