“…11 Consequently, advanced technologies like thermographic analysis and computational fluid dynamics (CFD) are critical in order to analyse these new indoor extreme ambiences. 3,12 In this sense, in previous research works, the engine room of some merchant ships were sampled and a first estimation of the maximum time that a marine engineer could be working in so hot environment was made. Nevertheless, many of them were only preliminary studies with average data, in such a way that it was not possible to define the better indoor ambience in accordance with the different tasks developed in the engine room.…”

Maritime transport is one of the primary international objectives for energy saving and pollution reduction, in agreement with the International Maritime Organization. Within the most interesting energy-saving topics, the ventilation system of the engine room must be highlighted, which represents about 5% of the nominal power of a modern ship. Nevertheless, its energetic optimization is not simple and must consider also work risk criteria, since the engine room is the hottest and, in consequence, one of the hazardous places in the ship. In this research, a complete three-dimensional computational fluid dynamics model of the engine room of a real ship has been developed in order to identify the hottest places and fully characterize their thermal conditions. On the basis of this analysis, a mathematical model of the maximum working time allowed has been defined, which can be directly used to design an efficient control algorithm for the ventilation system. In a complementary way, the minimum time required to rest in the control engine room to release the cumulated heat has also been analysed, in order to optimize its set-point conditions.

Melting of metals generally used the energy source of natural gas which is flowed through a pipeline at high pressure. Production activities in companies that use these gases have high potential hazards because they can cause fires or explosions if not managed properly. This study aims to analyzed natural gas dispersion in the event of gas pipeline leak, determine assembly point and evacuation route map plan for workers in the event of emergency condition. Natural gas dispersion was simulated using Computational Fluid Dynamic Ansys Fluent. Results of simulation showed distribution concentration of natural gas indoors at leakage almost uniform with concentration between 5%-13,17%. At that concentration the mixture of air and natural gas has the potential to explode because it is in the range of natural gas flammability. The maximum natural gas concentration of 13.17% at a height of 12 m above the leak hole. Generated two points Assembly point based on the calculation of blast radius with total area of 58,500 cm2 and can accommodate as many as 65 workers.

Considering that about 90% of international trade is transported via sea and ship ventilation systems consume between 3.5% and 5.5% of the ship’s rated power, ship energy consumption is of particular interest and modelling and enhancing ventilation systems are vital to reducing and optimising energy consumption. Using Computational Fluid Dynamics (CFD) simulation, modelling heat transfer and airflow patterns helped us improve the ventilation system and temperature distribution, provide thermal comfort for staff and equipment, and increase energy efficiency. We discussed the radiation effect in CFD analysis; it affected wall temperatures significantly and temperature contours to some extent; it raised air temperatures by 3 K and wall temperatures by 14 K in some areas; this issue has not been considered in previous analyses. Considering seven different engine room configurations, we analysed temperature distribution, air terminal streamlines and other parameters to choose the best. We examined four energy-saving plans for the best configuration, and airflow was reduced by 13.8% and fan power by 36% based on the temperature distribution. By improving the engine room ventilation system, average engine room temperature, heat removal efficiency, combustion air temperature, and temperature distribution developed. The analysis of air terminals included assessing their streamlines, determining areas they circulated, and customising their airflow; in addition to vertical and horizontal air terminals at the top or bottom of the engine room, we also examined a separate air terminal for engine combustion air, this tool has been used very little before.
