To acquire the skills to safely manage hazardous energy in hydraulic and pneumatic systems. The course teaches how to effectively isolate pressurised systems to prevent the sudden release of fluids or mechanical energy, which could lead to serious injury or turbine failure.

Course objective
Course description
The training focuses on the practical application of safety procedures in fluid mechanics:
- Hazard identification: recognising high-pressure systems, hydraulic accumulators and potential leak points,
- LOTO (Lockout/Tagout) procedures: practical training in locking out valves and hydraulic mechanisms,
- Residual energy management: safely relieving pressure from systems and accumulators before commencing maintenance work,
- Personal protective equipment (PPE): selection of appropriate gloves and eye protection to prevent hydraulic fluid from being injected under the skin (high-pressure injection injuries).
Duration
Prerequisites
- Possession of a valid WINDA ID number,
- At least 18 years of age,
- Basic technical knowledge of mechanics or hydraulics,
- Completion of the GWO BTT Hydraulic (Basic Technical Training) module is recommended, or equivalent professional experience.
Outcomes upon completion
The participant is able to correctly identify isolation points within the wind turbine’s hydraulic systems. They are fully prepared to safely perform residual pressure bleed-off procedures and apply appropriate mechanical lockouts to prevent unintended system re-energization. Furthermore, they can accurately recognize the risk of high-pressure fluid injection and are capable of providing immediate first aid in such an event.
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 prior to 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: durable clothing that can get dirty (exercises involving hydraulic components),
- Work shoes with a steel toe cap.

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.
