Abstract

Underwater and bathymetric surveys performed in 2011 have shown a deposition of waste coal ore in front of the jetty of the PJB Paiton port in East Java. The coal ore falls through the space between the barge and the jetty into the water during the unloading process (bringing the coal ore from the barge into the conveyor of the electricity generator). This coal deposition can hinder the coal barges while maneuvering in the harbor. Considering the port operational continuity, a number of questions arise: (i) How is the waste coal distributed in the bottom of the harbor? (ii) What is the rate of the coal deposition? (iii) Should dredging be carried out in the immediate time? To answer the above questions, hydro-oceanographic surveys have been carried out, measuring the bathymetry, tides and currents. Furthermore, hydrodynamic modeling was done to predict the magnitude and direction of the current in the harbor region, based on the data obtained from the hydro-oceanographic surveys. Simulation results have shown that the current speed is much lower than 1 m/s, not sufficient to distribute the coal ore relatively far from where it fell. In other words, the waste coal is locally deposited, which is consistent with the results of the underwater observations. These show that coal deposition is observed only in the vicinity region of the jetty, that is, within a distant not larger than approximately 2 m in front of the jetty. Furthermore, the rate of coal deposition is approximately 0.4 m/year or 2 m in 5 years. Considering barges with a maximum draft of 6 m, it is recommended to dredge the coal deposition before 2020.
