What are the applications of magnets in ships and ocean engineering?
Magnets have a variety of applications in marine and marine engineering. The special properties of magnets make it play an important role in various aspects of these fields. The following will introduce several applications of magnets in ships and ocean engineering.
Magnet Bottom Coating: The bottom of a ship is susceptible to algae and marine organisms, which can increase hydrodynamic resistance and lead to increased fuel consumption. To solve this problem, ships often use magnet-coated bottom plates. The magnetic force of the magnet can attract ferromagnetic attachments so that they cannot attach to the bottom of the ship, thereby reducing hydrodynamic resistance and improving the energy-saving effect of the ship.
Magnet drive system: In some small boats, magnets can be used as the core component of the drive system. By utilizing the attraction and repulsion forces of magnets, contactless transmission can be realized. This transmission mode will not produce mechanical wear and has good sealing performance, which is suitable for the harsh conditions of the marine environment.
Magnet Navigation: The magnetism of the magnet can be used in the navigation system of the ship. Ships often use a compass for navigation, and the compass uses the magnetic properties of magnets. The compass senses the earth's magnetic field to determine the direction of the ship, making navigation more accurate and safer.
Magnet positioning: In areas such as ports and docks, it is necessary to accurately locate the position of the ship. The magnet can be used in the positioning system of the ship, and the position of the ship can be determined by sensing the change of the surrounding magnetic field, which is convenient for the berthing and operation of the ship.
Offshore power transmission lines: In offshore engineering, it is necessary to transmit electrical energy from places such as offshore wind farms to land. Magnets can be used for support and fixation of offshore transmission lines. Because the magnet has a strong adsorption force, it can firmly fix the transmission line and improve the stability and safety of the line.
Magnet mining: There are a lot of mineral resources in the ocean, such as seabed oil and gas, manganese nodules, etc. Magnets can be used in ocean mineral exploration and mining. By utilizing the magnetic adsorption characteristics of magnets to minerals, the collection and development of mineral resources can be effectively carried out.
Submarine pipeline installation: In subsea engineering, it is often necessary to install subsea pipelines, such as oil pipelines, gas pipelines, etc. The magnet can be used for the positioning and fixing of the pipeline. Through the magnetic adsorption force, the pipeline can be firmly fixed on the seabed to avoid the movement and floating of the pipeline.
Submersible manipulation: Submersibles are important equipment for underwater work and scientific research. Magnets can be used to control the maneuvering of the submersible. By placing a magnet between the submersible and the maneuvering device, the movement of the instrument can be manipulated magnetically. By controlling the adsorption force and repulsion force of the magnet, the position and direction of the submersible can be precisely manipulated to complete various underwater work tasks.
To sum up, the application of magnets in ships and marine engineering includes ship bottom coating, transmission system, navigation system, positioning system, offshore power transmission line support, magnet mining, submarine pipeline installation and submersible maneuvering, etc. These applications take advantage of the special properties of magnets, such as magnetic attraction, repulsion, and induced magnetic fields, providing innovative solutions to various problems in marine and marine engineering. Through the rational use of magnets, the energy-saving performance of ships can be improved, the safety and efficiency of marine engineering can be improved, and contributions can be made to the development of navigation and marine industries.
"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
