marine telephones

Despite the dominance of radio communication and satellite phones in ocean-going voyages, shipboard telephones remain an indispensable tool for crew communication and emergency situations.

Shipboard telephones provide a convenient and fast internal communication method for crew members. On large vessels, crew members may be distributed across various decks and compartments. Using telephones allows for the quick conveyance of information, enhancing work efficiency. For instance, the captain or department heads can quickly contact crew members at specific posts via telephone for work guidance or emergency scheduling.

Telephones also play a significant role in the safety management of ships. In the event of emergencies such as fires, mechanical failures, or medical emergencies, telephones can serve as a tool for rapid alarm and coordination of rescue efforts. The ship's telephone system is typically connected to the internal public address system, allowing the captain or the person in charge of emergencies to quickly issue alerts and instruct crew members to take appropriate emergency measures via the telephone.

From a technical standpoint, the design of shipboard telephones usually takes into account the special requirements of the marine environment. They are typically waterproof, dustproof, and shock-resistant to adapt to the damp, salty, and vibrating shipboard conditions. Moreover, the telephone lines and interfaces are specially treated to ensure reliable communication during adverse weather or emergency situations.
