Safe working at height training in accordance with GWO standards

Working at Height Tower

The Working at Height Tower has been specifically designed for training participants in safe working, rescue, and evacuation techniques at height. The tower is widely used for GWO (Global Wind Organisation) courses, such as Working at Heights, and also provides training opportunities for offshore, maritime, and industrial scenarios.

What makes this tower unique is its versatility: participants can practice fall protection, climbing and descent techniques, as well as rescue and evacuation procedures. With multiple platforms and training stations, the tower is suitable for both basic and advanced levels.

Who is it for?

The Working at Height Tower is used by wind industry teams, offshore and maritime personnel, industrial technicians, and emergency responders who need to work safely at height or on elevated installations.

Safe training for offshore transfers

Boatlanding

The Boat Landing has been specifically designed to let participants realistically practice transferring from a work or transfer boat to a platform or installation. This is a crucial skill in the offshore and wind industries, where safe access and evacuation often depend on boat transfers.

What makes the Boat Landing unique is that participants can safely train their balance, timing, and climbing techniques while transferring. The motion of waves and moving vessels is simulated, allowing realistic practice under the close supervision of experienced instructors who ensure safety throughout.

Who is it for?

The Boat Landing is used by wind industry teams, offshore workers, and maritime personnel who regularly travel to their workplace by transfer boat and need to perform safe transfers. The facility is ideally suited for training in accordance with GWO (Global Wind Organisation) standards.

What You’ll Practice

Under the guidance of experienced instructors, participants will learn to:

  • Safely transfer from a boat to a ladder or platform

  • Use personal protective equipment and harness systems correctly

  • Maintain balance and timing when affected by wave motion

  • Climb up and down ladders under realistic conditions

  • Perform rescue and evacuation procedures during transfer incidents

  • Communicate and work together effectively during boat transfers

All exercises are conducted under strict safety protocols and concluded with a debriefing to reinforce key learning points.
