Proper Procedure for Responding to Distress Alerts Using Digital Selective Calling Techniques

Digital Selective Calling (DSC) techniques have revolutionized the way distress alerts are transmitted and received in the maritime industry. When a distress alert is received, it is crucial for ship stations to follow the proper procedure to ensure a swift and effective response. This article will outline the steps that should be taken upon receipt of a distress alert transmitted using DSC techniques. 1. Set Watch on the DSC Alerting Frequency Upon receiving a distress alert, the first step is to set watch on the DSC alerting frequency in the band of frequencies the alert was received. This allows ship stations to monitor any further communication related to the distress alert and be prepared to respond promptly. 2. Set Continuous Watch on VHF-FM Channel 13, 16, and DSC on Channel 70 In addition to monitoring the DSC alerting frequency, it is essential to set a continuous watch on VHF-FM Channel 13 and 16, as well as DSC on Channel 70. These channels are designated for distress and safety communications and serve as important means of communication during emergency situations. 3. Respond Using Narrow-Band Direct-Printing Equipment (If Available) Ship stations equipped with narrow-band direct-printing equipment should respond to the distress alert as soon as practicable using this means. Narrow-band direct-printing equipment allows for the transmission of distress messages in a clear and concise format, ensuring that the distress information is accurately conveyed to the appropriate authorities. 4. Set Watch on the Radiotelephone Distress and Safety Frequency Finally, it is crucial to set watch on the radiotelephone distress and safety frequency associated with the distress and safety calling frequency on which the distress alert was received. This ensures that ship stations are able to receive any additional distress messages or updates related to the initial alert. By following these proper procedures, ship stations can effectively respond to distress alerts transmitted using DSC techniques. It is important for maritime professionals to be familiar with these procedures and to regularly practice emergency response drills to ensure a swift and coordinated response in times of distress.
