The Global Maritime Distress and Safety System (GMDSS) ensures vessels have the means to communicate in emergencies. Testing and certification services include verifying the functionality of GMDSS components such as satellite communication, EPIRBs, and distress alarms. Certification confirms that all systems are compliant with international maritime regulations, ensuring that the vessel is fully equipped to handle emergency situations. Regular testing and certification provide peace of mind that the vessel will have reliable communication during a crisis, aiding in timely rescue and preventing serious safety incidents.
