Electrical Engineering I - M124V (for Shell employees only)

This course is the first technical electrical course in the professional development program for Shell Electrical Engineers.

It has been developed through a collaboration with Shell and PetroSkills and is focused on getting electrical engineers up to speed with the essential principles of electrical safety, system design and maintenance. Additionally, this course introduces the participants to the critical elements of relevant Shell DEPs that they will use in their daily work.

The course focuses on foundational concepts rather than regional code and standard requirements, but does cover common international (IEC, EN, BS, etc.) and North American (NEC, IEEE) standards related to design and safe operation.

This intensive program is held over 10 8-hour sessions in two weeks and has been designed to be delivered virtually. As such, the expectation is that participants fully engage online, ask and answer questions posed in the course and participate in meaningful discussions related to the concepts, implications, and application of the concepts. A sample project will be completed in phases throughout the course, giving the participants an opportunity to work with their peers in solving typical design challenges and applying concepts and Shell standards. Offline time will be allotted before, during, and after the course to allow participants to complete assignments at their own pace.

At the end of the course, participants will complete a formal written final exam, and must pass or remediate the exam to receive credit for the course.

Target Audience

This course has been designed for Electrical Engineers with a bachelor's or master’s degree (or equivalent) in electrical engineering and 1-3 years’ experience on the job and Senior Electrical and Instrument Technicians or Supervisor whose activities include work on electrical equipment in refineries, gas and chemical plants or oil field installations.

It is assumed that participants will come to the course with academic background in the fundamentals of AC and DC electricity, 3-phase power systems, basic electrical mathematic principles (Ohm's Law, Kirchhoff's laws, etc.), phasor math, basic understanding of the role of common industrial power system equipment and components (Substations, Generators, transformers, switchgear, protective devices, cables, conduit, etc.). 

Basic knowledge of Shell internal systems including locating Shell and Industry standards is expected.

It is beneficial if students have some practical experience working in industrial facilities so that they can understand the context of the material presented.

This course will be held in English. Participants should be fluent in English with proficiency such that they can participate in technical discussions.

You Will Learn
