Abstract


Coal unloading ports at a steam power plant (PLTU), the size of barge or ship is determined based on the needs of coal consumption each month and the safety factors that considers period of downtime due to weather factor. The percentage of downtime when the design is calculated to be distributed in a period of time can last for several weeks and cause a break in the supply of coal to the power plant in a long period of time. Regarding this condition, it is necessary to use bigger ship capacity. The size of ships served in some PLTU must be evaluated. This article discusses a case of port capacity evaluation in one of PLTU in Southern Coast of Java if it was able to serve a ship with bigger size. An evaluation to the capacity of pier pole structure was done by using SAP2000 software and the evaluation of pier dimension, fender and bollard capacity, as well as the depth and the area of existing turning basin that have been done by using port design standards. The result of the evaluation is an early indication for the size of ships which still can be served by the existing port PLTU.
