Class A AIS Compliance and Maintenance: Best Practices for Maritime Operators
For shipping companies and ship operators, ensuring the compliant operation and effective maintenance of Class A AIS is not only a legal obligation but also a key link to ensuring voyage safety and avoiding operational risks. This article summarizes the compliance points and maintenance best practices of Class A AIS to help maritime professionals standardize equipment management.
Key Compliance Points for Class A AIS
In recent years, maritime authorities around the world have continuously strengthened the supervision of AIS equipment. Operators must pay attention to the following compliance requirements to avoid penalties <superscript>1<superscript>4:
24/7 Continuous Operation: Class A AIS must be kept running at all times during the voyage, except in cases where international agreements or standards require the protection of navigational information. It is strictly prohibited to shut down the equipment without authorization; if it is shut down due to power failure, it must be restarted immediately after power recovery and the reason must be recorded in the navigation log.
Authentic and Consistent Information: The static and dynamic information of AIS must be true, accurate, and consistent with the ship's certificate. It is prohibited to tamper with information such as MMSI code, ship name, and call sign, or use other ships' codes.
Complete Certificate Documentation: The AIS equipment must have complete product certificates, AIS identification code certificates, and radio station licenses. The information on the certificates must be consistent with the ship's inspection certificate.
Qualified Operator Operation: On-board duty personnel must be proficient in AIS operation, including viewing information, troubleshooting simple faults, and handling alarms. Lack of operational skills may be deemed non-compliant during inspections.
Permanent Information Curing: For Class A AIS installed on board on or after October 1, 2025, the manufacturer ID, equipment model, serial number, MMSI code, and ship identification number must be permanently cured to prevent tampering <superscript>1.
Daily Maintenance Best Practices for Class A AIS
Scientific daily maintenance can extend the service life of Class A AIS and ensure its stable performance. The following maintenance measures are recommended:
Daily Inspection: Check the power supply status, display screen clarity, and antenna connection of AIS every day. Ensure that the equipment displays the ship's own information and surrounding ships' information normally, and there is no abnormal alarm.
Regular Cleaning: Clean the display screen and host unit regularly to remove dust and moisture. Avoid using corrosive cleaning agents to prevent damage to the equipment.
Cable Inspection: Regularly check the antenna cable and power cable for damage, aging, or loose connections. Replace damaged cables in a timely manner to avoid signal loss or power failure.
Software Update: Cooperate with the equipment manufacturer to update the AIS software and firmware in a timely manner to fix potential bugs and adapt to the latest regulatory requirements.
Fault Handling: If AIS malfunctions (such as positioning failure, information transmission error), it should be reported to the maritime authority immediately, and the maintenance process should be recorded in the navigation log. Do not disassemble or modify the equipment without authorization.
The Importance of Compliance and Maintenance
Non-compliance with Class A AIS regulations may lead to penalties such as ship detention and fines, affecting the normal operation of the ship. At the same time, poor maintenance may cause equipment failure, resulting in loss of navigation information, increased collision risks, and even serious maritime accidents. Therefore, shipping companies should establish a sound AIS equipment management system, strengthen the training of on-board personnel, and ensure that Class A AIS is always in a compliant and effective operating state.
In the context of increasingly strict global maritime regulations and continuous improvement of navigational safety requirements, Class A AIS, as a key equipment for ship safety, will play an increasingly important role. Mastering its compliance requirements and maintenance skills is an essential ability for every maritime professional.
