| Zusammenfassung: | The needs to reduce energy consumption have to be applied to all sector, and one of them is transportation. Shipping is the most significant component of it, and therefore optimising a ship performance and reducing its resistance is a subject for many researchers. One of many ways to reduce drag is by utilising an alternative design such as multihull vessel, especially pentamaran, a vessel with five hulls. Destructive interference between their system of waves produced by their hulls is beneficial to reduce power consumption. An experimental test of X-pentamaran model in calm water condition had been conducted to investigate the interference resistance. Wigley hull-form of the model with four asymmetric-hull configurations and three variations of hull separation was investigated. The ship model was towed in a fixed towing condition and calm water condition with Froude number ranging from 0.2 to 0.7. The results showed that the hull separation made a slight alteration of the total resistant coefficient (in magnitude) on the same configuration. Even though not a single configuration outperformed the others in the entire range of Froude number, two configurations with S/L=0.11 showed the highest drag reduction performance as the optimum model based on their Froude number range: configuration A3 from Froude number ranging from the initial to 0.6 and configuration C3 for the rest of the Froude number range. |
