Design, Modelling and Application of Microcontroller (MCU) on Ballast Water System

Abstract

Onboard ship there is ballast water treatment plant , where the prior to loading and discharging, the ballast water would pass through 3 stage of process prior loading of discharge. The purpose of this paper is to create a differential pressure system for the main strainer in loading ballast water. This is an essential step to eliminate particles and sediment from entering the ballast tank. We would be using a microcontroller to monitor the inlet pressure and the outlet pressure from the main strainer. Comparing the data of the inlet and outlet pressure. When there is a difference in pressure. The microcontroller would stop the loading ballast water into the system and begin backflush of the strainer. The process shall be repeated till the inlet and outlet pressure difference is below set limit.
