About this service
Communication and navigation you can rely on
A radio survey checks that a ship’s communication and navigation equipment works and meets the required standards. Berth Marine inspects and tests the equipment, repairs and calibrates communication and voyage systems, and provides a detailed report.
Regular surveys keep the vessel safer on passage and in line with international maritime conventions.
