Automation & controls
Modern vessels equipped with sophisticated machinery and new technologies need careful handling during operations and maintenance. It has been realized that there is growing need for developing and honing the skills of Marine Engineers to understand the working, maintenance and troubleshooting of the various automated control equipments.
This course is designed to prepare the Marine Engineer to face the challenges of modern vessels in Automation and Control. It addresses the earlier, but still widely prevalent, pneumatic automation devices as well as the more modern Programmable Logic Controller.
This course provides a forum for theory lecture delivery, computer simulation exercises, hands on training on the pneumatic components as well as on the PLC and group discussions leading to improvement in competency and confidence in handling automation equipment.
On completion of this course, the participant should be able to understand:
- Concepts of automatic control.
- Working and maintenance of Temperature, Pressure, Flow, Level and other measuring equipment.
- Operation and maintenance of various types of Transmitters, Controllers, Actuators, Valve Positioners and control valves with their characteristics.
- Boilers controllers-Boiler water level controller and Air/Fuel combustion controller.
- Operation and maintenance of the Automatic Controller along with calibration.
- The operation and maintenance aspects of the Programmable Logic Controller.
