Designing according to the EN13445 code

About The Course

Cultivate expertise in the EN13445 design code, the essential standard for unfired pressure vessel design compliant with the Pressure Equipment Directive (2014/68/EU). In an era where automated software often obscures the calculation process, this course restores clarity by elucidating the foundational equations and principles that underpin these design rules.

Explore critical questions such as the area replacement rule, the application of the Taylor and Forge method, and the inner-stiffener distance required to prevent vacuum-induced collapse. Gain insights into distinguishing between primary and secondary stresses and their evaluation within the code.

This course extends beyond rote application, challenging participants to understand the rationale behind each rule’s formulation. Moreover, it highlights key distinctions compared to the ASME BPVC Section VIII Division 1 code.

This course is self-paced and is not subject to specific dates. The course contains 9 modules with a total of 7 hours of content which can be performed at your own pace. A personal certificate will be provided to you if you finish the course within the first month after purchase. This incentive aims to motivate you to perform the course in a timely manner, thereby improving your learning curve.


This course is scheduled regularly with a drip feed of modules becoming available to the participants throughout the program. The drip schedule aims to provide consistency to your learning experience and is designed to maintain participant concentration and provide adequate time to perform exercises between live instructor sessions where the instructor may answer any questions about the topic.

The dates of the course are organized upon inquiry.


This course is scheduled over a duration of 2 work days. The dates of the course are organized upon inquiry.

This course is available in self-paced, hybrid, and classroom formats.

Prerequisites and level

  • None
  • Level: Foundational

Intended For

This course is designed for:

  • Those required to design pressure vessels as per the EN13445 and that want a solid overview and understanding of the design methods used in the code.
  • Engineers that already have experience with the EN13445 and that want to improve their understanding of the backgrounds for the different rules and methods applied in the code.
  • Technicians involved in the production of EN13445 unfired pressure vessels that want a solid understanding of the design basis of their vessels.

Access to the course
After your purchase is confirmed you receive an account to the EngineeringTrainer online learning portal, where you find the course in your dashboard. After opening the course you will be guided step-by-step through the different modules. You receive 1-year unlimited access to the course. This allows you to perform modules again if this is beneficial for your work projects.

Learn by doing
The course is mainly based on video content: video lectures and video software demonstrations. English subtitles is available and videos can be viewed as many times as desired. The video lectures help you to grasp the important technical concepts and in the video demonstrations the instructor uses the software and discusses all the steps and actions.
