Investigation of environmental factors on the resistance characteristic: Study case of the designed patrol boat hull

Abstract

Abstract The increase in world oil prices has led to high operational costs in the maritime sector. In this regard, it is necessary to increase efficiency in the use of fuel in the maritime transportation security sector. Resistance on the ship’s hull affects efficiency and fuel consumption. In previous studies, there have been analyses on internal factors of the ship’s hull, such as appendages, which can affect the resistance value of the ship’s hull. However, examination of the external factors, e.g., the condition of the waters during operations of patrol boats, is still scant. This study conducts a series of analyses of the influence of environmental factors on the hull resistance values, such as water density and wind speed, with five different conditions. The results of this study are expected to be a reliable reference in predicting hull performance under different environments, especially in an attempt to reduce fuel consumption due to resistance.
