Ship recycling with a way to reduced hazardous effect on the environment

Abstract

Ship recycling is a complex process of dismantling of the obsolete vessel, during this process a large amount of hazardous waste is produced which causes great environmental and health impact. To reduce this effect many laws and regulation are implemented but still there are cases of environmental impacts. This work is carried out to minimize the effect of hazardous material produced during ship dismantling. The data was collected from ship recycling yard of kolkata port trust. The list of quantity of hazardous material, average cost of disposal, average cost of transportation and storage cost is obtained. I consulted with maritime expert that is surveyors, ship recycling managers, chief engineers who suggested to use Analytic Hierarchy Process. Criteria in this process is based on expert suggestion and most preferred way for obsoleting vessel was found to be dry docking, Further based on data of quantity of hazardous material the preferred way of ship obsoleting was proposed. Further most hazardous material was calculated based on ship yard policy and it was found to be Asbestos and PCB. This method can be used in the industry as it give a whole view about best recycling method for green ship recycling, preferred method for vessel obsoleting based on inventory of hazardous material and also suggest potential hazard present in recycling yard based on ship recycling yard policy.
