GMDSS radio survey is an inspection of the radio equipment on board a vessel to ensure that it meets the required standards and is functioning correctly. The survey is carried out to verify that the vessel’s radio equipment is in compliance with the International Maritime Organization (IMO) regulations and is capable of transmitting and receiving distress alerts, maritime safety information, and general communications.

The primary purpose of GMDSS radio survey is to ensure that the vessel’s radio equipment is fully operational and compliant with the GMDSS regulations. The survey aims to verify that the equipment is capable of transmitting and receiving communications and alerts, such as distress calls, search and rescue, and navigational warnings. The survey also ensures that the equipment is in good condition and properly maintained.

There are two types of GMDSS radio survey:

1. Initial survey
   An initial survey is conducted before the vessel is put into service to verify that the radio equipment meets the requirements.
2. Renewal survey.
   A renewal survey is conducted periodically to ensure that the vessel’s radio equipment continues to meet the regulations. The frequency of the renewal survey depends on the type of vessel and its operating area.

Several parties are involved in GMDSS radio survey, including

1. the Administrations
2. Recognized Organizations (ROs)
3. Radio Surveyors.

Role of Administrations

The Administrations are responsible for enforcing the GMDSS regulations in their respective countries. They authorize and supervise the ROs and the radio surveyors and issue the necessary certificates.

Role of Recognized Organizations (ROs)

ROs are organizations authorized by the Administrations to carry out surveys on their behalf. The ROs conduct the GMDSS radio survey and issue the necessary certificates to vessels that comply with the regulations.

Role of Radio Surveyors

Radio surveyors are individuals authorized by the ROs to conduct GMDSS radio surveys on vessels. They inspect the radio equipment and verify its compliance with the regulations. They also prepare the survey reports and issue the necessary certificates.

To ensure that the radio equipment on board a vessel meets the required standards and is fully operational, there are specific requirements that must be met. These requirements include general requirements, specific requirements for different vessels, and consequences of non-compliance.

General Requirements

The general requirements for GMDSS radio survey include:

• The survey must be conducted by a qualified and authorized surveyor or a recognized classification society.
• The survey must verify that the vessel’s radio equipment meets the IMO regulations and is capable of transmitting and receiving distress alerts, maritime safety information, and general communications.
• The survey must verify that the vessel’s radio equipment is in good condition, properly maintained, and fully operational.
• The survey must ensure that the vessel’s crew is trained and familiar with the use of the radio equipment.

Specific Requirements for Different Vessels

Different types of vessels have specific requirements for their radio equipment. These requirements are based on the vessel’s size, type, and the waters in which it operates. The specific requirements include:

• For passenger ships, the radio equipment must be capable of transmitting and receiving distress alerts, ship-to-ship communications, and public correspondence.
• For cargo ships, the radio equipment must be capable of transmitting and receiving distress alerts, ship-to-ship communications, and weather reports.

• For fishing vessels, the radio equipment must be capable of transmitting and receiving distress alerts and ship-to-ship communications.
• For pleasure craft, the radio equipment must be capable of transmitting and receiving distress alerts and general communications.

Consequences of Non-Compliance

Non-compliance with GMDSS radio survey requirements can have severe consequences. The consequences include:

• The vessel may be detained until the necessary corrections are made.
• The vessel may be fined or penalized.
• The vessel’s insurance coverage may be affected.
• In case of an emergency, the vessel’s radio equipment may not function correctly, which can lead to loss of life or property.

GMDSS radio survey is conducted in three phases: pre-survey activities, survey activities, and post-survey activities.

Pre-Survey Activities

Pre-survey activities include:

• Reviewing the vessel’s documents and radio equipment.
• Coordinating with the vessel’s master to schedule the survey.
• Ensuring that the surveyor has the necessary tools and equipment.

Survey Activities

Survey activities include:

• Verifying that the vessel’s radio equipment meets the requirements.
• Checking the condition and maintenance of the equipment.
• Verifying that the vessel’s crew is trained and familiar with the use of the equipment.

Post-Survey Activities

Post-survey activities include:

• Preparing the survey report and documentation.
• Notifying the relevant authorities of any deficiencies or non-compliance.
• Advising the vessel’s master of any necessary corrective actions.
