What we have been working on.
Updates when something changes, when we build something useful or when there is a subject worth explaining properly.
IGEM/UP/1B Edition 4 is here. We are helping engineers get ready.
Edition 4 was published in March and becomes effective on 1 October 2026. We have built a free calculator to support installation volume, permissible pressure-drop and purge-volume work while engineers become familiar with the new edition.
Use the calculator as practical support and always verify the result against the current standard, your training and safe working procedures.

Why we keep building free tools for engineers.
Standards change, phones replace notebooks and the job keeps moving. We have worked hard to turn common calculations and on-site prompts into simple tools that engineers can reach quickly, without a subscription or an account.
They are there to help nobody feel left behind. They do not replace proper training, manufacturer instructions or competent judgement.

From Derek · 26 February 2024
Starting your career in gas engineering.
A training route should give you sound knowledge, practical experience and the confidence to keep learning safely once you enter the industry.
At TomKat, the focus is on clear explanations, small classes and hands-on time. People arrive with different backgrounds, so questions are encouraged and support is personal.
Training is only the beginning. Building competence takes supervised experience, proper testing, current industry knowledge and a willingness to ask when you are unsure.
