Requirements from a operator of existing wind power plants perspective
Every wind power plant has a secured ladder so, from the point of view of occupational safety, there is no need to retrofit with a significantly safer system. Ergonomic climbing has long been a desirable criterion, but this is not usually by itself sufficient to persuade operators, service companies and plant manufacturers to retrofit with a manual mechanical climbing system.
The decisive added value lies in reaching the nacelle comfortably by lift, instead of having to climb oneself.
Nowadays, lifts have long been standard in two or three storey buildings. No one wants to do without this easy way of reaching upper floors. But why did not that also apply for so long to wind power plants, which are much higher? 50, 60 and 80 metre towers have been built without being equipped with a convenient means of access. Instead, one relied on the conventional, totally inconvenient ladder. Everyone had to take this strenuous access route to reach the nacelle.
- The existing ladder should remain usable for manual climbing
- The investment must be in proportion to the benefit. The direct, measurable benefit is the profit made by the wind power plant.
- The retrofitting has to be easy and inexpensive
- Existing processes, such as rescue in emergencies, must not be changed
- The use of additional equipment should not increase maintenance expenditure
