Telemedical Assistance Services (TMAS) provide remote medical advice to vessels at sea, ensuring crew health and safety during long voyages. Regular maintenance of the TMAS ensures that communication lines between the vessel and medical professionals onshore remain open. Service includes ensuring that satellite communications and audio equipment are working properly, testing the emergency response systems, and updating software as needed. TMAS maintenance ensures that vessels are prepared to handle medical emergencies effectively, providing peace of mind to crew members and meeting regulatory health and safety requirements.
