As underwater explorers, submarines have an edge in discovering the beauty and mysteries of the ocean. However, this advantage also puts them at risk of entanglement with fishing nets. If a submarine gets caught in a fishing net, it can lead to catastrophic damage to both the submarine and the surrounding ocean environment. Therefore, submarines are equipped with several features that enable them to avoid fishing nets.
One of the critical mechanisms used by submarines to avoid fishing nets is sonar. The sonar system sends out sound waves and then measures the time taken by the sound to reflect back to the submarine from different objects, including fishing nets. The feedback generated by the system is used to create an image of the surrounding environment, allowing the onboard personnel to detect and avoid fishing nets. The sonar system can detect even the slightest of obstructions like fishing nets and can provide precise information about their location, size, and shape. This information helps the submarine crew to maneuver the vessel safely.
Submarines also have a feature called passive sonar. This technology detects sounds generated by other vessels, including fishing boats. Submarine operators use these sounds to track the movements of nearby boats, and the information collected enables them to avoid areas where fishing nets might be deployed. Passive sonar is incredibly useful for submarines that are operating in shallow waters where fishing nets are more common.
In addition to sonar, submarines also employ various other methods to avoid fishing nets. For example, they can use underwater cameras to capture images of the sea floor and identify obstacles like fishing nets. Some submarines also carry small underwater drones that can be sent ahead of the vessel to scout for any potential hazards.
Submarines are equipped with advanced equipment and technology that enable them to avoid fishing nets effectively. The sonar system and passive sonar are the critical tools that submarine crews use to detect and avoid fishing nets. With these advanced features, submarines can navigate safely and avoid damage to themselves and the surrounding environment. The safety of the crew and the ocean environment is always a top priority for submarine operators. Therefore, they continue to develop and implement new features that enable safe and successful underwater navigation.
