Unit Description and General Aims
This unit provides the students sufficient depth of practical understanding of the principles, design, configuration, testing, installation, commissioning and maintenance of process control systems in the context of the oil and gas industry.
The underlying principles of process control and system requirements (functional and technical arising from end user, process control, separation of process control from safety instrumented functions, system architecture, communication networks, power, earthing, and environmental) will provide the student with an understanding of how to systematically identify and apply these principles to control system design based on commercially available systems (Distributed Control Systems, Programmable Logic Controllers and SCADA Systems). Practical aspects of overall project development and the impact on process control system design development and integration will be addressed as will control system operation and maintenance.
On successful completion of this Unit, students are expected to be able to:
- Identify and analyse principles of Process Control System Engineering to onshore and offshore Oil & Gas facilities.
- Evaluate disciplined and practical engineering processes to enhance the lifecycle performance of process control systems.
- Analyse and Apply sound engineering practices, and demonstrate understanding of process control hardware and design.
- Evaluate and apply principles for interfacing packaged equipment control systems.
- Recommend and apply principles for incorporating design information into the system design development.

Project and Revision
In the final weeks students will have an opportunity to review the contents covered so far. Opportunity will be provided for a review of student work and to clarify any outstanding issues. Instructors/facilitators may choose to cover a specialized topic if applicable to that cohort.
Completing this unit will add to students professional development/competencies by:
- Fostering the personal and professional skills development of students to:
- Be adaptable and capable 21st century citizens, who can communicate effectively, work collaboratively, think critically and innovatively solve complex problems.
- Equipping individuals with an increased capacity for lifelong learning and professional development.
- Planning and organising self and others
- Instilling leadership qualities and a capacity for ethical and professional contextualization of knowledge
- Enhancing students’ investigatory and research capabilities through:
- Solving complex and open-ended engineering problems
- Accessing, evaluating and analysing information
- Processes and procedures, cause – effect investigations
- Developing the engineering application abilities of students through:
- Labs / practical / case studies / self-study (where applicable)
Web & Video conferencing software
Students will be provided with Blackboard Collaborate (or similar) for video and web conferencing. This will allow them to attend lectures, interact with lecturers and fellow students, and use the Remote Lab facility. Students will be required to download the latest version of Java and .NET in order to use these packages.
For ease of communicating with peers and lecturers, installation of this package is recommended.
Word, PowerPoint and Excel
It is recommended that students install at least a 2007 version of the Microsoft Office. Older versions will work, but sometimes create issues with file compatibility. If individuals are reluctant to use these, they can also use Open Office (www.openoffice.org).
As students are co-operating with people from throughout the world with a multitude of different PCs, it is recommended that they have good quality up-to-date virus detection software installed. The free version of AVG is sufficient. A thorough automated scan of computers at least once a week is recommended.
Learning Management System
EIT uses a state-of-the-art learning management system (Moodle) for lecturing and interacting with lecturers and fellow students. Students can chat, socialize, and collaborate on projects with similarly motivated and enthusiastic course participants.
Computing resource requirements
Students’ computers should have an Intel Core Duo CPU and 2 Gigabytes of RAM. Hard disk space available should be at least 2 Gigabytes free. If necessary the built-in hard drive can be augmented with an inexpensive USB drive. No particular special graphics card is required. The operating system should be Windows with Windows 7 Service Pack 1 as a minimum.
An ADSL Internet connection with a minimum speed of 128 kbps down and 64 kbps up is recommended.
Good quality headset and low cost web cam
Students will require a good quality stereo headset with analogue or USB connectors. In addition, a low-cost USB webcam is recommended. Students should budget in the order of $30 for a headset and $20 for a webcam. This will vary from country to country.
For difficulties with other online materials the lecturer should be contacted. Technical material will be accessible 24/7 through the online portal.
