Abstract: The wheelhouse windows will be iced by seawater droplet and climatic conditions such as rain and snow for vessels operating in extreme cold environments. It will obstruct the view from the wheelhouse and thus threaten the navigation safety, making the deicing design for the wheelhouse windows critically important. Aiming at optimizing the deicing effect of the wheelhouse windows under extreme cold environments, it studies the causes of icing on the surface of the wheelhouse windows. Using this as input conditions, the electric heating deicing of the wheelhouse windows are numerically simulated and analyzed to provide the deicing effect of different electric heating powers under different external ambient temperatures. An electric heating deicing solution is finally proposed for the wheelhouse windows under extreme cold environments.

Key words: extremely cold environment, wheelhouse windows, electric heating power, deicing effect
