Testing and diagnosing communication equipment aboard vessels is essential for ensuring reliability and compliance with safety standards. This service includes checking systems like VHF radios, satellite phones, and AIS for proper functionality, signal strength, and potential interference. Routine diagnostics help identify any issues that could disrupt communication. Ensuring that communication systems are in optimal condition reduces the likelihood of communication breakdowns, increases operational safety, and ensures the crew can effectively communicate with other vessels, shore stations, and emergency responders.
