Bridge-to-bridge Communications


In the maritime context, bridge-to-bridge communications refer to the direct communication system between the bridges of two vessels, or between a vessel and a port authority. This communication is crucial for coordinating maneuvers, avoiding collisions, and ensuring the overall safety of the vessels involved. The communication is typically facilitated through VHF radio channels, specifically channel 16 (156.8 MHz), which is internationally recognized as the maritime safety and communication frequency. The bridge-to-bridge communication system is governed by the International Telecommunication Union (ITU) and the International Maritime Organization (IMO). The system is designed to be clear and concise to avoid misunderstandings, with English being the standard language used. In addition to voice communication, modern systems may also include digital messaging for clarity and record-keeping. The use of bridge-to-bridge communication is not only a best practice but is also mandated by law in many regions, including in the United States under the Bridge-to-Bridge Act of 1971.
