What this course about?

In the oil, gas and petrochemical industry, precision control of the flow of product through valves in the system is vital, and modulation of that flow depends on the valve actuator. These critical pieces of equipment must perform reliably and safely under the most extreme conditions: very high and low temperatures, drought or high-rainfall environments, remote situations in deserts or the arctic, and the corrosive effects of chemicals, high humidity or salinity for extended periods. In potentially explosive atmospheres, explosion protection is required; and in some applications, fireproof operation is critical.

In addition to the core function of opening and closing the valve, the actuator forms a crucial interface between the process and the supervisory control system, providing seamless integration into whichever distributed control system (DCS) is used in the plant network. Moreover, where the Industrial Internet of Things (IIoT) plays a role, electric actuators equipped with powerful electronics must serve as information hubs, providing direct access to a wide variety of both process and diagnostics data.

Plant and pipeline operations depend on a high degree of valve automation for fundamental functions. The complex processes involved with the flow of material, pumping stations, compressor stations, etc., require the valve positioning to be accurate and extremely reliable.

Actuators must operate the full range of valves—from ball valves, butterfly valves, gate valves to others—to control the flow of both gas and liquids. Typically, ball or butterfly valve actuation requires part-turn actuators that provide a swivel movement of generally 90 degrees for full travel. Gate valves, on the other hand, typically need multi-turn actuators that provide a high number of turns to operate the valve from open to close and vice versa

Another differentiation is the type of duty the actuator has to perform, whether that’s open/close or modulating. Actuators used to isolate a segment, allow maintenance or interruptions in the process, or in worst case stop a leak, are required to operate infrequently to open or close shut-off valves.

Modulating actuators, on the other hand, provide enhanced positioning accuracy for control valves to precisely modulate the flow within pipes. In the upstream segment, this is for the flow of crude oil and natural gas; in the midstream segment, it’s for the storage and transportation of resources. In the downstream segment, this is for the refining process of crude oil, as well as the sale and distribution of both the refined product (i.e., gasoline, fuel, asphalt, etc.) and to feed raw materials to a variety of petrochemical industries that use petroleum-based products to make plastics, fertilizers, pharmaceuticals and more.

Frequently Asked Questions (FAQ)

Training can take place in 4 formats:

  • Self-paced
  • Blended learning
  • Instructor-led online (webinar)
  • Instructor-led offline (classroom)

Description of training formats:

  • Self-paced learning or e-Learning means you can learn in your own time and control the amount of material to consume. There is no need to complete the assignments and take the courses at the same time as other learners.
  • Blended learning or "hybrid learning" means you can combine Self-paced learning or e-Learning with traditional instructor-led classroom or webinar activities. This approach requires physical presence of both teacher and student in physical or virtual (webinars) classrooms or workshops. Webinar is a seminar or presentation that takes place on the internet, allowing participants in different locations to see and hear the presenter, ask questions, and sometimes answer polls.
  • Instructor-led training, or ILT, means that the learning can be delivered in a lecture or classroom format, as an interactive workshop, as a demonstration under the supervision and control of qualified trainer or instructor with the opportunity for learners to practice, or even virtually, using video-conferencing tools.

When forming groups of students, special attention is paid to important criteria - the same level of knowledge and interests among all students of the course, in order to maintain stable group dynamics during training.

Group dynamics is the development of a group in time, which is caused by the interaction of participants with each other and external influence on the group. In other words, these are the stages that the training group goes through in the process of communicating with the coach and among themselves.

The optimal group size for different types of training:

  • Self-paced / E-learning: 1
  • Instructor-led off-line (classroom): 6 – 12
  • Instructor-led on-line (webinar): 6 – 12
  • Blended learning: 6 – 12
  • Workshop: 6 – 12
  • On-the-job: 2 – 4
  • Simulator: 1 – 2

Feedback in the form of assessments and recommendations is given to students during the course of training with the participation of an instructor and is saved in the course card and student profile.

In order to control the quality of the services provided, students can evaluate the quality and training programme. Forms of assessment of the quality of training differ for courses with the participation of an instructor and those that are held in a self-paced format.

For courses with an instructor, start and end dates are indicated. At the same time, it is important to pay attention to the deadlines for passing tests, exams and practical tasks. If the specified deadlines are missed, the student may not be allowed to complete the entire course programme.

A personal account is a space for storing your training preferences, test and exam results, grades on completed training, as well as your individual plan for professional and personal development.

Users of the personal account have access to articles and blogs in specialized areas, as well as the ability to rate the completed training and leave comments under the articles and blogs of our instructors and technical authors

Registered users of a personal account can have various roles, including the role of a student, instructor or content developer. However, for all roles, except for the student role, you will need to go through an additional verification procedure to confirm your qualifications.

Based on the results of training, students are issued a certificate of training. All training certificates fall into three main categories:

  • Certificate of Attendance - students who successfully completed the course but did not pass the tests and exams can apply for a certificate of attendance.
  • Certificate of Completion - students who have successfully completed a course could apply for a Certificate of Completion, this type of certificate is often required for compliance training.
  • Verified Certificate - it is a verified certificate that is issued when students have passed exams under the supervision of a dedicated proctor.

You can always download a copy of your training certificate in PDF format in your personal account.

You will still have access to the course after completing it, provided that your account is active and not compromised and Tecedu is still licensed for the course. So if you want to review specific content in the course after completing it, or do it all over again, you can easily do so. In rare cases, instructors may remove their courses from the Tecedu marketplace, or we may need to remove a course from the platform for legal reasons.

During the training, you may encounter various forms of testing and knowledge testing. The most common assessment methods are:

  • preliminary (base-line assessment) - to determine the current level of knowledge and adapt the personal curriculum
  • intermediate - to check the progress of learning
  • final - to complete training and final assessment of knowledge and skills, can be in the form of a project, testing or practical exam

Travel to the place of full-time training is not included in the cost of training. Accommodation during full-time studies can be included in the full board tuition fees.

While Tecedu is not an accredited institution, we offer skills-based courses taught by real experts in their field, and every approved, paid course features a certificate of completion or attendance to document your accomplishment.

Smart Virtual Classroom (open digital / virtual classroom).

Conducting classes is based on the fact that the teacher demonstrates text, drawings, graphics, presentations on an interactive board, while the content appears in the student's electronic notebook. A specially designed digital notepad and pen are used to create and edit text and images that can be redirected to any surface via a projector.

Classes are live streamed online, automatically recorded and published on the Learning Portal, allowing you to save them for reuse anytime, anywhere, on any mobile device. This makes it possible not to miss classes and keep up with classes and keep up with the passage of new material.
