Resource Requirements Software

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.

Skype

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).

Virus detection

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

Computer

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.

Internet

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.

Technical Help

For difficulties with other online materials the lecturer should be contacted. Technical material will be accessible 24/7 through the online portal.

Unit Description and General Aims

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.

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.

The Engineering Institute of Technology (EIT) is dedicated to ensuring our students receive a world-class education and gain skills they can immediately implement in the workplace upon graduation. Our staff members uphold our ethos of honesty and integrity, and we stand by our word because it is our bond. Our students are also expected to carry this attitude throughout their time at our institute, and into their careers.
