Radio Survey & GMDSS Inspection Services

Independent MARINA Accredited Radio Survey and GMDSS inspection services supporting SOLAS Chapter IV compliance, communication system reliability, operational testing, troubleshooting, programming, repair support and new installation assistance.

Radio Survey & GMDSS Communication System Inspection

A vessel radio survey is a mandatory comprehensive inspection of the ship's GMDSS (Global Maritime Distress and Safety System) and communication equipment to verify compliance with SOLAS Chapter IV requirements and applicable IMO regulations.

PAMS Pacific Admiralty Maritime Services provides independent marine radio survey, inspection, testing and technical consultancy services to ensure vessel communication systems remain fully operational, correctly certified and ready for emergency response.

Our radio surveys cover the inspection, operational testing, documentation review and compliance verification of critical communication and safety equipment including EPIRBs, SARTs, AIS, VHF radios, MF/HF communication systems, satellite communication equipment and emergency power supplies.

The objective is to confirm that the vessel can reliably transmit distress alerts, maintain required communication capability and comply with Flag State, Classification Society and SOLAS requirements.

Independent technical verification: A properly conducted radio survey establishes the operational condition, certification status, documentation and emergency communication readiness of the vessel's GMDSS installation.
