Strength Analysis of Vessel Ship Type PBL Conversion From Barge

Abstract

One of the stages in evaluating ship design is the calculation of the strength of the ship's length. So we need a support tool that can speed up the calculation process. Therefore it is necessary to develop a program for calculation, as an alternative to evaluate the strength of the ship's length. Analysis of the strength of the length of the vessel to determine the strength of the length of the ship which is the result of conversion from the barge. Lengthening strength calculations using numerical methods with the help of the maxsurf study version program. Voltage price checks are carried out on three loading conditions, namely (1) empty load conditions, (2) FWT, FOT conditions , in conditions of 50% and (3) full load conditions (working conditions) . The results of this study are in the form of a calculation of the longitudinal strength of the vessel in operation. The final output of this program is in the form of a latitude and mom style curve in the longitudinal direction of the ship. The results of the calculation of the strength of the longitudinal PBL vessel results from the shear force and moment. Shear force on loadcase 2, and 3 conditions in the parallel position of the midle body of the frame frame 25 longposes 58 and 60 meters in a row. Whereas in the 1 shear force loadcase at fram 26 post length 58 meters.The maximum load case 1 moment is 7,605  10 3 tonne meters. Loadcase 2 is 10.232  10 3 tonne meters, while in loadcase 3 is 9,974  10 3 tonne meters. Keywords— longitudinal strength, software, shear force, momen, PBL ship
