Design And Implementation of a PLC-and-HMI-Based Watertight Door Control System Prototype On a Self Elevating Platform Vessel

Abstract

Abstract — Safety compartments on a ship type selfelevating platform very depends on performance watertight door inside prevent water seepage in conditions emergency. Operation door manually or semi - automatically on some ship units Still leaving gap in the form of slowness time responsiveness and lack of supervision centralized, so that potential lower reliability system safety. Article This describe the design process get up A prototype controller automatic For watertight door which utilizes programmable logic controller (PLC) and human machine interface (HMI) as the core of control and monitoring. hardness used includes Siemens S7-1200 PLC, Omron NB7W HMI panel, stepper motor driven through TB6600 driver, as well as limit switch as detector position end door. Prototype This is also equipped feature warning early ( alarm ) and locking interlock so that the command control local and centralized No each other collide. Trial done on two scheme operation, namely control local through push button and control centralized through order central close on HMI, each repeated several times to evaluate consistency Work every function. Test results show that all over function start from motor movement, detection limit switch, activation alarm, until status display on HMI running in accordance design on each experiment. Centralized mode proven capable close all over sliding door in a way simultaneously at a time disable control local, while indicators on the HMI update the door status in a way direct and accurate. Prototype This show that PLC and HMI integration is feasible considered For increase reliability system safety watertight door in the environment boat.
