The engine room indicator, shown in Fig. 11.3, is an aluminium bulkhead mounted cabinet installed in the ship's engine room for general monitoring of the port and starboard fins. FIG. 11.3 . Engine room indicator panel.

Mar 1, 2024 · Firstly, the initial 3D layout scheme of engine room equipment is automatically obtained by the KBE method including knowledge acquisition, knowledge representation and knowledge reasoning. Then the multi-objective optimization of ship engine room layout is performed by the simulated annealing algorithm (SAA) to acquire the optimal design scheme.

Aug 1, 2023 · In an engine room fire, the flow of hot smoke in the upper of the room and the stratification of the smoke mainly depend on the ventilation air velocity. As the ventilation velocity increases, the high-speed airflow formed by the ventilation system forces the exhaust of smoke, and the high turbulence of the smoke enhances the heat transfer ...

Sep 15, 2013 · The model focuses on a ship engine room with multilayer structures, and the non-uniformity of ventilation within the engine room is considered. Moreover, the software of Fire Dynamics Simulator (Version 5) is used to reconstruct the 3D fire field within the specified engine room with multi-spaces.

Dec 1, 2024 · To reach the final result, engine room parameters (e.g. type of engine room, layout, dimensions …) had to be defined. After that, the most common fire scenarios inside the engine room were selected. The third step marked the beginning of parallel work on a) building a CFD model and b) building a VR environment.

Sep 5, 2016 · Similar considerations can be extracted from other modern studies, estimating that nowadays more than 35% of the accidents on board occur in the engine room, in such a way that any redesign of the engine room ventilation system requires the consideration of the current regulations on labour risk prevention, in addition to energy efficiency ...

Jan 1, 2016 · The engine room space is meshed using the Hypermesh Software, with 1,259,127 elements and 232,534 nodes, as illustrated in Fig. 2. To obtain high grid quality, grid refinement is applied in areas with large gradients, such as air inlets, outlets and gas leakage areas.

Feb 15, 2024 · In the engine room environment studied in this paper, if the volume fractions of 1 % and 4 % hydrogen are taken as the lower and upper limits for the sensor to detect hydrogen, the sensors should be installed at or above 5.5 m in the rear of the engine room and above the axis of the hydrogen transport pipeline interface, valves and other places ...

Feb 1, 2025 · At 90s, the harmful volume in the engine room is 824.34 m 3, which has reached a high value. At 120s, the harmful volume in the engine room is 855.72 m 3, the volume of hazardous gases slightly grows, and the warning region accumulates only on one side of the leakage hole, leaving nearly no warning region on the other side.
