Bridge navigational watch alarm system (BNWAS) is abbreviated as BNWAS. Its main function is to prevent pilots from failing to perform their duty while navigating. When the above situation occurs, the system will produce a series of gradually extended alarms. Until the attention of the duty officer or Captain and authorized duty officer is drawn to ensure that the duty officer performs his duty.
In addition, the BNWAS system can also provide on-duty pilots with immediate call-for-help measures. At any time, the BNWAS system is working, except for the captain's prohibition. The system meets the requirements of MSC. 128 (75) and IEC 62616 (2010), and is suitable for installation and use of various types of ships, including ships with front and rear dual steering systems.
Bridge refers to the ship's cab, port and starboard compass deck, observation, observation, command positions, front, rear, left and right steering gear and other duty positions.
