Effects of Appendage Addition on the Hull Resistance During Patrol Boat Operations

Rising oil prices have been a major concern for many industries, and the maritime industry is no exception. The cost of fuel is a significant part of the operational expenses for ships, including patrol boats. Therefore, to reduce the impactImpact of increasing oil prices, there is a need to increase the efficiency of fuel use in patrol boats. 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 conducted a series of analyzes of the effect of adding turn fin and bilge keel lathe attachments to the ship hull on the resistance value. The results of this study are expected to be a reliable reference in predicting hull performance with different equipment, especially in an attempt to reduce fuel consumption due to resistance.
