ABSTRACT
In 1997, the Russian tanker Nakhodka, weighing 13,157 tons, sank off in the Japan Sea reportedly causing an oil spill. The oil spill had a serious impact on the shoreline environment. The purpose of this poster is to present a method to estimate the number of workers needed to clean the shoreline with maximum efficiency and minimum redundancy. In this study the parameters of manual oil removal are estimated and the framework in which those parameters work is explained. The results show that the amount of oil removed in a day correlates with the cumulative amount of oil removed up to that day and the number of people engaged in cleaning up on that day. The equation predicting the amount of oil is: S = 13.4827 E − 0.03874 C + 38458.1525 R2 = 0.918, F (2,34) = 192.28,p<0.01where S = the amount of oil removed in a day (liter), E = the number of people engaged in cleaning up on that day, C = the cumulative amount of oil removed up to that day (liter), R = correlation coefficient, F = degree of freedom. With this equation, the total amount of stranded oil that can be collected on a certain day and the number of people necessary to remove the spilled oil at the most efficient rate can be estimated. One can also calculate the optimal number of workers for the task.
