Fungsi Peralatan GMDSS (Global Maritime Distress and Safety System)

Summary

This video provides an in-depth explanation of essential GMDSS (Global Maritime Distress and Safety System) equipment on ships. It covers devices such as MF/HF DSC, Navtex, EPIRB, SART, and Inmarsat, explaining their functions in maritime safety. The MF/HF DSC is crucial for receiving distress signals, while Navtex broadcasts important navigation and weather warnings. EPIRBs and SARTs are used for emergency signaling and rescue operations. The video also highlights how these devices help maintain safety at sea by ensuring effective communication and positioning during emergencies, underscoring the importance of registering these devices with national authorities.

Takeaways

• 😀 GMDSS (Global Maritime Distress and Safety System) covers essential maritime communication tools for distress and safety.
• 😀 The MF/HF DSC (Digital Selective Calling) system is crucial for receiving distress alerts and passing emergency messages.
• 😀 Navtex is an international frequency used to broadcast navigation and meteorological warnings, helping vessels stay updated with safety information.
• 😀 EPIRB (Emergency Position-Indicating Radio Beacon) helps detect distress signals on frequencies 121.5 MHz and 406 MHz, aiding in search and rescue operations.
• 😀 Starting from February 1, 2009, EPIRB only works on the 406 MHz frequency for better satellite communication.
• 😀 SART (Search and Rescue Transponder) helps locate survival craft and individuals during emergencies by transmitting signals that can be detected by radar.
• 😀 SART operates in the 9 GHz frequency band and allows for both audio and visual signals to help rescue operations.
• 😀 The range of SART detection is influenced by the radar height on ships and can cover about 15 km or more.
• 😀 Inmarsat allows for the transmission of voice, text, and data communications, even when vessels are beyond conventional communication ranges.
• 😀 GMDSS equipment must be registered with national authorities, ensuring efficient coordination and quick responses during distress situations.

Q & A

What is the purpose of the MF/HF DSC equipment mentioned in the video?

The MF/HF DSC (Digital Selective Calling) system is used to automatically receive and send distress messages and alerts. It operates on dedicated channels and helps relay distress calls, safety messages, and navigational warnings.

What is the role of Navtex in maritime communication?

Navtex is an international frequency system used to automatically broadcast important maritime safety information, such as meteorological warnings, navigational alerts, and search and rescue updates. It transmits messages in English or Indonesian, depending on the frequency.

What is the function of the Emergency Position Indicating Radio Beacon (EPIRB)?

The EPIRB is a safety device that transmits distress signals at specific frequencies (121.5 MHz and 406 MHz). These signals are received by satellites and forwarded to the Rescue Coordination Center (RCC) for processing and rescue operations.

What happens when an EPIRB is activated?

When an EPIRB is activated, it sends a signal to satellites. The signal is then relayed to the RCC and eventually to the Mission Control Center (MCC), where the ship's position and distress information are processed for rescue purposes.

Why is it important to register the EPIRB with national authorities?

Registering the EPIRB ensures that the authorities, such as Basarnas in Indonesia, can quickly access the ship’s details and respond to distress situations by pinpointing the vessel’s location and other critical information.

What is the purpose of the Sharp (SAR Transponder) mentioned in the script?

The Sharp (SAR Transponder) is used to improve the detection of Survival Craft during search and rescue operations. It works by emitting signals that can be detected by radar systems on vessels or aircraft, aiding in locating survivors.

How does the Sharp system work to aid in rescue operations?

The Sharp system operates on a 9 GHz frequency band and transmits signals when detected by radar. It helps locate Survival Craft or survivors by providing both visual and audio signals, improving the efficiency of rescue efforts.

What is the significance of the radius of detection for the Sharp transponder?

The detection radius for the Sharp transponder can reach up to 15 km, depending on the height of the radar tower and the altitude of the device. This range is designed to cover a significant portion of the world’s oceans, enhancing rescue operations.

How does the geostationary satellite system work for maritime communication?

Geostationary satellites orbit at the same speed as Earth’s rotation, ensuring they remain fixed over a specific point on the Earth’s surface. This allows continuous communication coverage, including for distress calls and important updates from maritime areas.

What are the key benefits of GMDSS equipment on ships?

GMDSS (Global Maritime Distress and Safety System) equipment ensures effective communication for distress, safety, and navigational information. It enhances safety by providing systems like DSC, Navtex, EPIRB, and SAR Transponders, which help with both routine communications and emergency response.
