Abstract
In the present economic and environmental circumstances, energy efficiency has become more and more important. In order to maximize energy efficiency in the marine sector, both on the scale of individual ships and the overall industry, this article undertakes particular research on ship trim optimization. The first point of interest will be an examination implemented on ships with the aim of diminishing their consumption of fuel by trim optimization where is one of the simplest and least expensive ways to boost performance and save costs. This study was conducted on a displacement type vessel using the CFD approach with initial calculations on the even keel conditions at operational speed, v = 12 knots. Following that the ship will be applied a stern trim from 0.5 to 2.5 degrees. Finally, an investigation of the needs for resistance and energy was carried out. The findings of the simulation indicate that when the ship is trimmed to a state of 0.5 degrees, it is able to reduce the amount of energy required by the ship's main engine by 4.63%. The most effective means of reducing the ship's overall energy usage are ship-trim activities.
