Highlander’s Singapore team are qualified surveyors conducting radio survey on behalf of all the major Classification Societies. It is important that emergency and safety equipment is inspected and are in good condition. The purpose of such measures is to verify the condition of the ship and its equipment are maintained to conform with the provisions of the SOLAS regulations to ensure that the ship in all respects will remain fit to proceed to sea without danger to the ship or persons on board.

All our surveyors in our Radio Survey Team are well trained and capable of all other survey activities together with GMDSS radio survey at once; such as VDR / S-VDR annual performance test, AIS / SART / EPIRB annual performance test, or Gyro Annual Maintenance.
