Model development of estimating oil discharge for sustainable green port

Abstract

Port is indeed a complex system build up from multi-subsystem, i.e. ecology, technology, economy and most importantly the community of human workforce within. As for the range of activities occurred within the port has been globally diversified, the port size also urged to expand. To that extend, maintaining port operation, has degraded the magnitude of responsibility towards the environment’s concern. Fulfilling the need, this study was conducted to highlight the important of green port. This will be done by investigating the sources and impact from oil pollution that occurred at the terminal port container. Conducting the study, a set of objectives was established; to design and develop System Dynamics (SD) model of environmental sustainable green port operation, and to suggest mechanism for minimizing the oil pollution based upon the developed model. In order to do that, SD’s computer simulation was designated by using VensimTM Software. The model demonstrating the oil pollution’s time based design analysis which propagate the interrelation of all the causes and repercussions involved. A case study was exclusively selected on oil discharge that occurred within Port Tanjung Pelepas (PTP), Johor. From the basis of previous record provided by PTP Marine Department, equations model was derived prior to the development of the SD simulation. Calculation of Cohen’s Kappa for the model construct was calculated with value of 0.671. From the simulation result, it was found that, the oil discharge is expected to be significantly increased annually. Provided that there is no preventive measure was taken, in range of 20 years’ time, more than 350, 000 m3 is expected to be observed. Treatment cost may speed up to RM30 billion annually by year 2035. On that basis, this study suggests that countermeasures need to be taken by implementing higher security level at the port and provide training about the importance of environment.
