To acquire the knowledge and skills required to effectively control hazardous electrical energy during maintenance and installation work. The course teaches how to correctly isolate systems to prevent accidental electric shock or the uncontrolled release of energy (e.g. an electric arc).

Course objective
Course description
The training focuses on the practical application of electrical safety procedures:
- LOTO (Lockout/Tagout) procedures: learning how to apply locks and caution notices / tags to disconnectors,
- Voltage verification: rules for safely testing systems before commencing work,
- Electrical risks: understanding the hazards posed by residual energy (e.g. in capacitors) and electric arcs,
- Standards and legislation: an overview of safety requirements specific to wind turbines.
Duration
Prerequisites
- Possession of a valid WINDA ID number,
- At least 18 years of age,
- Basic electrical knowledge (SEP or similar qualifications are welcome),
- Completion of the COHE Basic Safety theory module or technical experience in the industry is often required.
Outcomes upon completion
The participant is able to correctly and safely perform electrical energy isolation procedures. They are fully prepared to apply appropriate lockout/tagout (LOTO) devices and effectively verify a zero-energy state. Furthermore, they can accurately recognize warning signs and faults within electrical safety systems, performing all assigned tasks in strict accordance with the Safe System of Work.
Certificate validity
The certificate is valid for 24 months (2 years). To maintain your certification, you must complete a refresher course within the last 2 months before the expiry date of your current certificate.
Information regarding the completed training will be recorded in the international GWO WINDA database. The digital record enables authorised employers to instantly verify your qualifications. For the participant, this means easy confirmation of competence worldwide without the need for paper documents.
What to bring
- Valid ID card or passport,
- Workwear (or comfortable technical clothing),
- A notebook and pen – the course covers many important procedures and diagrams.

Why choose us?
Certified and audited GWO training centre
We offer one of the broadest training portfolios on the market and operate in accordance with international Global Wind Organisation standards. The quality of our training, the competencies of our instructors and our infrastructure are regularly audited.
ONLY AT IM TRAINING: a globally unique PCTC crew course using a full-scale training facility
We have a specialist training ground where participants practise realistic scenarios, including firefighting operations on PCTC vessels, RO-RO vessels and ferries, as well as hazards associated with electric vehicle fires.
We were the first in Poland to introduce GWO High Voltage courses
We made competencies available in Poland that previously required training abroad, reducing the time companies need to prepare teams for onshore and offshore projects.
End-to-end training organisation
We manage the entire process, from agreeing a suitable date and arranging transport and accommodation to delivering the training and preparing complete documentation. We also provide end-to-end support for groups and teams travelling from abroad.
Realistic, modern training infrastructure
We train participants using specialist equipment, full-scale structures, training towers, simulators and a pool, so they can practise procedures rather than simply hear about them.
Partnerships with industry and academic leaders
We work with Energy Innovation in Norway and leading maritime institutions in Poland: Gdynia Maritime University and the Polish Naval Academy. We combine international industry experience with expert knowledge and the resources of Polish maritime universities.
We care about more than just training

Why do companies and course participants choose IM Training?
Employees return ready to work
The training is practical and delivered in conditions similar to real workplace situations. Our employees return with the required certificates, but above all with knowledge and skills they can use at work.
I am very satisfied
I took two GWO courses and I am very satisfied. There was plenty of hands-on practice and realistic simulations, and the instructors explained everything clearly and patiently.
End-to-end support
IM Training efficiently organised training for our international team, including the logistics, language and formal requirements. Thanks to the effective coordination, we could focus on the project without involving our own team in organising the trip.
Highly competent instructors
The practical sessions after the theory are eye-opening. The instructors are highly competent and the course was delivered thoroughly.
Fast scheduling and flexibility
The training dates were aligned with our team mobilisation schedule. The quick response, flexible approach and option to train a larger group on the same date made it significantly easier to prepare our employees for the project.
Very good facilities and workstation preparation
A repair techniques course. Very good facilities and workstation preparation, efficient organisation and a high standard of practical training.
The training material was thoroughly covered.
Very good training delivered by competent instructors. The sessions were engaging, the time passed very quickly and there was plenty of hands-on practice. The training material was thoroughly covered.
Modern equipment, no nonsense
The working at heights course is mainly practical: equipment, fall protection and emergency scenarios. Everything was well organised, the instructors were direct and clear, and the equipment was modern. No nonsense.
