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.
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.
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.
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.
This unit provides depth of understanding of the principles, design, configuration, testing, installation, commissioning and maintenance of Emergency Shutdown (ESD) systems in the context of the oil and gas industry.
The underlying principles of ESD system requirements (hazard management, safety instrumented functions, safety requirements and design development, field instrumentation interfaces, system design architecture, operator interface(s), alarm systems, packaged equipment, cabling, power, earthing and environmental control.) will provide the student with an understanding of how to systematically identify and apply these principles to ESD system design based on commercially available products. Practical aspects of overall project development and the impact on ESD system design development will be addressed as will system operation and maintenance.
On successful completion of this Unit, students are expected to be able to:
Identify and apply principles of ESD system engineering to onshore and offshore Oil & Gas facilities.
Apply disciplined and practical engineering processes to enhance the lifecycle performance of ESD systems.
Analyse, apply and demonstrate in-depth understanding of ESD related hazards and systems.
Evaluate and recommend principles for incorporating design information into system design development.
Evaluate and apply principles for the operation and maintenance of ESD systems.

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.
