How do you deal with GMDSS interoperability and compatibility issues with other communication systems?

1 Know your systems

The first step to deal with interoperability and compatibility issues is to know your systems well. You should be familiar with the functions, features, and requirements of each communication system you use, as well as the relevant regulations and procedures. For example, you should know how to operate the GMDSS equipment on board, such as the VHF, MF, and HF radios, the Inmarsat terminals, the NAVTEX receiver, and the EPIRB. You should also know how to use other communication systems, such as the Iridium or VSAT satellite phones, the AIS transponder, the email and internet services, and the cellular networks. You should also be aware of the limitations and advantages of each system, such as the coverage, reliability, cost, bandwidth, and security.

2 Choose the right system for the right purpose

The second step to deal with interoperability and compatibility issues is to choose the right system for the right purpose. You should use the most appropriate communication system for the task at hand, depending on the urgency, importance, and nature of the message. For example, you should use the GMDSS system for distress, urgency, and safety communications, as it is designed to ensure priority, alerting, and coordination of rescue operations. You should also use the GMDSS system for routine communications with coast stations and other ships, as it is regulated by the International Telecommunication Union (ITU) and the International Maritime Organization (IMO). However, you may use other communication systems for non-essential or personal communications, such as the satellite phones, email, internet, or cellular networks, as they may offer more convenience, flexibility, and affordability.

3 Coordinate with other parties

The third step to deal with interoperability and compatibility issues is to coordinate with other parties involved in the communication. You should establish and maintain contact with the relevant coast stations, rescue centers, and other ships, and inform them of your communication systems and preferences. You should also follow the common protocols and standards for communication, such as the ITU Radio Regulations, the IMO Resolutions, the SOLAS Convention, and the GMDSS Master Plan. You should also respect the frequency allocations, channel assignments, and call signs of each communication system, and avoid interference or confusion. Moreover, you should be prepared to switch to alternative communication systems if needed, and inform the other parties of any changes or problems.

4 Test and maintain your systems

The fourth step to deal with interoperability and compatibility issues is to test and maintain your systems regularly. You should ensure that your communication systems are in good working order, and that they meet the performance and safety standards set by the GMDSS and other authorities. You should also conduct periodic tests and checks of your systems, such as the radio tests, the battery tests, the antenna tests, and the software updates. You should also keep a record of your tests and maintenance activities, and report any faults or malfunctions to the appropriate service providers or agencies.

5 Train and update your skills

The fifth step to deal with interoperability and compatibility issues is to train and update your skills. You should have the necessary knowledge and competence to operate the communication systems on board, and to handle any emergency or routine situations. You should also have the relevant certificates and qualifications, such as the GMDSS General Operator Certificate (GOC) or Restricted Operator Certificate (ROC), or the Satellite Communication Endorsement (SCE). You should also attend regular training courses and workshops to refresh and enhance your skills, and to keep up with the latest developments and trends in maritime communication.

6 Seek help and advice

The sixth step to deal with interoperability and compatibility issues is to seek help and advice when in doubt or difficulty. You should not hesitate to contact the nearest coast station, rescue center, or other ship for assistance or guidance if you encounter any problems or challenges with your communication systems. You should also consult the relevant manuals, guides, or websites for more information or tips on how to use your communication systems effectively and efficiently. You should also join or follow professional associations or forums that deal with maritime communication issues, such as the International Association of Marine Electronics Companies (IAMEC), or the Maritime Communication Forum (MCF).
