The Evaluation on Resistance Model of Tanker Vessel and an Uncertainty Analysis

The most important in designing a ship is determining the value of resistance when talking about the hydrodynamic performance of the ship. The International Towing tank Conference (ITTC) procedure is recommended for resistance tests. Uncertainty analysis should be in terms of the reliability of the test results. Total uncertainty for single run of the total resistance coefficient (CT), and the residual resistance coefficient (CR) of 17,500 DWT Tanker model scale of 1:25 with the dimension of L = 5.980 m, B = 1.108 m and T = 0.280 m at Froude number 0.107-0.188 corresponding velocity of 0.82-1.44 m/s conducted at Indonesian Hydrodynamics Laboratory (LHI)- BPPT. The continuous improvement of laboratory performance and consistency of quality testing services is need by the national shipbuilding industry and impact on the competitiveness of national products in regional and global markets
