Navigation Equipment Inspection

The inspection of navigation equipment on a vessel involves systematic and thorough examination of various components and systems responsible for the vessel's navigation, safety, and orientation at sea or on water. The inspection process may vary depending on the type of vessel, its purpose, and specific requirements. However, in general terms, the inspection of navigation equipment may include the following:

  1. Development of an inspection plan, compilation of a task list, the components and systems to be checked, and selection of inspection methodology.
  2. Visual inspection. Inspection of navigation equipment for visible damages, wear, and corrosion, as well as checking the condition of antennas, cables, and connectors.
  3. Functional testing:
    • GMDSS testing according to manufacturer instructions and class requirements, including VHF, MF/HF, Inmarsat, EPIRB, SART, Emergency VHF, AIS, NAVTEX.
    • Measurement of transmitted signal response frequencies, ability to send Telex signals.
    • Measurement of deviation of received signal and transmitted and reflected power on any VHF channel.
    • Testing emergency frequency calls.
    • Compass testing - deviation test on different courses and issuance of magnetic compass deviation table.
  4. Diagnosis of errors and malfunctions. Evaluation of the causes of occurrence and their impact on navigation and overall safety.
  5. Tests under real conditions. In some cases, the inspection is conducted during a vessel's sea trial. This allows for equipment testing in real sea navigation conditions.
