Radio Survey & GMDSS Services

Annual radio surveys, GMDSS inspections and shore-based EPIRB & SART testing, by a DG Shipping approved radio surveyor, with certificates accepted by class, flag and PSC.

Overview

GMDSS compliance without the drama

Your GMDSS installation is the vessel's lifeline, and one of the most inspected systems on board. Our approved radio surveyors carry out annual radio surveys and equipment testing to SOLAS Chapter IV and IMO requirements, using certified test equipment and issuing documentation that passes scrutiny the first time.

Because we hold DG Shipping approval as a radio surveyor and service station, one visit can combine the survey with rectification, saving a second attendance if defects are found.

Frequently Asked Questions

Answers, straight from our surveyors

Cargo ships of 300 GT and above on international voyages require radio surveys in line with SOLAS and flag requirements, typically annually, within the window linked to the vessel's Safety Radio Certificate.
Annual testing is performed on board where conditions allow; shore-based maintenance (SBM) is arranged when required by the flag or when the beacon needs battery or HRU replacement. Both are performed to IMO MSC.1/Circ.1039.
We tell you immediately, quote the rectification, and, in most cases, repair or replace during the same visit from our stock of new and tested refurbished units, so your certificate is not held up.
Yes. Our reports and certificates are issued under DG Shipping approval and are routinely accepted by port state control, classification societies and flag administrations.
