선박용 유수분리기의 오일 모니터링 시스템 개발

Development of Oil Monitoring System for Oily Water Separator

Oil filtering epuipment referred to in regulation 16 of MARPOL 73/78 shall be of a design approved by the Administration and shall be such as will ensure that any oily mixture discharged into the sea after passing through the systems has an oil content not exceeding 15 parts per million. It shall be provided with alarm arrangements to indicate when this level cannot be maintained. The system shall also be provided with arrangements such as will ensure that any discharge of oily mixtures is automatically stopped when the oil content of the effluent exceeds 15 parts per million. For protection of marine pollution, at the moment, all ships should have oil filtering equipment which is satisfying requirements of MAPOL 73/78. In this study, to meet the requirements, Oil Montoring System (OMS-2000) which has oil detecting module and monitor & control unit is developed. The oil detecting module is divided into two parts, the one is data processing unit and the other is oil sensing module. The data processing unit use a microcontroller and the oil sensing module is consisted of a IR-LED light souce, several Photo-diode light receivers, and a glass tube for oily water sample. The monitor & contol unit realizes automatic operation of the filtering equipment and results in saving seafarer's manpower. Experiment results show good performance and easy operation of OMS-2000.
