Rockfall barrier energy classes explained
A barrier is sold by its kilojoule rating, but the number on the datasheet only means something once you know which rock, from which height, and how often.
Rope access, geotechnical, wind and NDT services
Engineering between the sky and the ground.
Geotechnical slope protection, wind turbine blade and tower services, and NDT inspection. Delivered by rope access teams that have worked at height across Europe and Türkiye.
One team, three disciplines, the same safety culture on every site.
Tengri Geo Energy is an engineering and field services company based in Türkiye. We stabilize slopes, protect roads and infrastructure from rockfall, keep wind turbines running, and inspect critical structures without destroying them.
Three disciplines, one access method

Why Tengri
Field-proven
Our team comes from wind turbine blade repair and rope access operations across Germany, the Netherlands, Scandinavia and Türkiye.
Certified and compliant
IRATA / SPRAT rope access technicians, GWO trained personnel, and documented method statements for every job.
One partner, less coordination
Geotechnical, wind and NDT under one roof, so you brief one team instead of three contractors.
In the old Turkic world the sky above was Tengri and the earth below was Yer-Su. Everything in between had to be read carefully. We still work that way: we listen to the ground, we respect the height, and we walk the path before anyone else does.

Rope access vs scaffolding: when each one makes sense
Rope access is not always the answer. It wins where getting to the work is the hard part, and it loses where the job needs a stable platform for weeks.
Leading edge erosion: when to repair, when to protect
Erosion starts as a surface problem and ends as a structural one. The cost of fixing it depends mostly on when you find it.
