There are many potential fire hazards in ship engine cabin, especially in the closed environment of submarine underwater. Fires in cramped cabin are usually harder to put out, therefore, enclosing cabin is a possible means of extinguishing fire. In this paper, typical fire scene in ship engine cabin is analyzed firstly, then a two-layer zone model of engine cabin fire is established combined with structural characteristics of engine cabin. According to the mass conservation and energy conservation, fire smoke layer change rule is described to estimate extinguishing time. At last, typical hydraulic jet fire and electrical fire smoke layer calculation is taken as an example. The result shows that enclosing cabin is a fast and effective method, and the method of estimating fire extinguishing time in engine cabin by this paper is feasible.
