Miniatur Loading Arm Dock-3 PT Badak NGL Bontang dengan Sistem Emergency Shut Down (ESD)

摘要

Loading Arms in PT Badak NGL are used to distribute natural gas for shipping. The position of the ship cannot be fixed due to the wind, sea wave, stream flow, etc. If the distance is out of tolerance limit, then the Emergency Shut Down (ESD) system will be activated. ESD will release the part that is connected to the ship so that the whole distribution pipe is safe. The loading arms are controlled via Programmable Logic Controller (PLC) manually. The miniature of the loading arms is useful to train the new employees to operate them well. It is build with 1:10 ratio and controlled by PLC OMRON C200 HG. Several DC motors are used to move the arms while potentiometers are used as position sensors. The PLC will monitor whether the position is within tolerance limit or not. From the experiments, the ESD can be implemented with 16.48s for slewing motion and 16.5s for extension motion.
