Abstract: When ships navigate in polar or high latitude regions, de icing and snow removal from the ship deck is a necessary task. The method of heating and melting ice has the advantages of not easily damaging deck coatings and steel substrates, and thorough de icing. Taking into account the principles of energy generation, heating efficiency, temperature control accuracy, and high energy consumption, the electromagnetic effect rapid heating de icing technology for decks is innovative and cutting-edge. According to research and analysis, there is currently no mature technology solution or mature device applied to ship de icing worldwide. Only the developing electric repulsion separation system has the possibility of future ship deck de icing applications, and its basic working principle is similar to the principle of electromagnetic effect rapid heating technology. A domestic unit has developed a ship electromagnetic effect rapid heating deck de icing device, which can be used to remove deck ice layers with a thickness of less than 30mm. It has the advantages of high efficiency, energy saving, precise control, fast response, cleanliness and environmental protection, making China's level of solving the problem of ship deck de icing in extremely cold navigation areas reach an advanced level.
