Projects

Over the years , during business NAWITEL we gained the biggest experience among the companies dealing with the horizontal directional drilling in Poland. Till today we have made more than 300 km of the HDD installations for: oil & gas , water - sewage , heating pipelines, energy and ICT .
 
Our greatest achievements :
 
1. The most complicated HDD instalation in terms of the ratio of length to diameter hole drilling
 
Crossing the Vistula River in Wloclawek 2012/2013 :
Length : 1,342 m
The diameter of the installed pipe : 711 mm
Pipe material : Steel
Purpose : gas pipeline
Depth of the hole axis : 45 m
 
 
2. The longest installation in Poland
 
Crossing under Ina River in Radziszewo 2014 :
Length : 1700 m
The diameter of the installed pipe : 219 mm
Tube material : Steel
Purpose : Optical
Depth of the hole axis : 72 m
 
3. The most complicated trajectory of drilling hole in Poland - azimuth change 600 with a radius of 500 m
 
Exceeding the forest areas in Wloclawek in 2014 :
Length : 1,335 m
The diameter of the installed pipe : 323.9 mm
Tube material : Steel
Purpose : gas pipeline
Depth of the hole axis : 19 m
 
Below is our list of references containing basic data , about some of our's finished projects. References from contractors given to us by the most significant of the installation industry in Poland.
