Details

Overview

Emergency Shutdown Systems (ESD) are a fundamental part of the safety systems associated with oil and gas, utility and other hazardous processes. Associated with these systems are specific valves which are used to isolate and blowdown the processes. These are referred to as Shutdown (SDV) and Blowdown (BDV) Valves respectively. Under emergency situations it is critical that these valves operate correctly. Thus the engineering of the valves and their associated actuators is paramount in ensuring plant safety. They must meet the Fire Safe and Reliability criteria determined by IEC16508 and IEC16511. This Professional Certificate of Competency (PCC) covers the requirements in detail.


In addition, the course addresses Severe Service Valves and Wellhead Choke Valves. Severe Service Valves are required where the process can cause damage to conventional valves through erosion, high noise, cavitation, high vibration, possible mechanical damage to the valve trim, other components and the process equipment around the valve. These valves are generally specialist designs that overcome these issues by "smart" design.

Professional Development Series

In order to meet the exacting demands of the oil and gas, mining, manufacturing and downstream processing industries, modern plants are equipped with systems and devices which are needed to measure and regulate variables such as temperature, pressure, flow, humidity, liquid level, velocity and density. Industrial Automation provides the technology to control and monitor a process plant using such concepts as feedback, cascade, feedforward and advanced process control. Here at the Engineering Institute of Technology (EIT), we have developed industry-focused programs in the form of vocational diplomas, advanced diplomas and graduate certificates, all the way up to Masters level in the higher education sector.

There is a critical shortage of automation, instrumentation and control engineers, technicians and technologists around the world now due to the retirement, restructuring and rapid growth in new technologies and industries. The respected International Society of Automation (ISA) organization estimated that at least 15,000 new automation engineers are needed annually in the USA alone.

In keeping with the philosophy of EIT, students in this school are exposed to the practical, up-to-the-minute knowledge and skills demanded by leading industries worldwide, with online instrumentation courses. EIT does not just cater to a generic student body, instead all of our online instrumentation courses are specific to industry. The programs cover a large range of topics and are suited to anyone needing an intensive and practical look at all facets of industrial automation, instrumentation and process control.

The short courses that form part of EIT's professional development series are designed to provide students with critical knowledge and practical tools that can be immediately applied to the workplace. They are ideal to up-skill and/or cross-skill in a particular area or technology and are not accredited programs.

Students in EIT's School of Industrial Automation, Instrumentation and Process Control study subjects which include: process control, instrumentation, control valves, process plant layout and piping design, tuning of process loops, SCADA, PLCs, advanced process control (APC), boiler control, hazardous areas, safety instrumentation (IEC 61511 and IEC 61508), HAZOPs, industrial data communications, networking, deviceNet and Fieldbus, industrial wireless, radio telemetry systems, shielding/EMC/EMI, and noise reduction.
