Zabok – Lučko

The gas pipeline Zabok - Lučko DN 700/75 bar is a closed technological system constructed from steel pipes with a nominal diameter of DN 700 and is dimensioned in accordance with the operating pressure of 75 bar. The entire length of the gas pipeline is constructed as an underground installation, with the exception of the construction of overhead facilities at the sites of installation of block stations (BS), launching and receiving scraper traps (MČS) and gas nodes (PČ). It will pass through the area of the Krapina-Zagorje County, i.e. the area of the towns of Zabok and Oroslavje, then the area of the Zagreb County, i.e. the area of the municipalities of Jakovlje and Bistra, the towns of Zaprešić and Sveta Nedelja, and the area of the City of Zagreb. The route of the planned gas pipeline is 36 km long and is expected to be located almost entirely in the corridor of the existing main gas pipeline Zabok - Zagreb DN 500/50 bar and the main gas pipeline Zagreb west - east DN 500/50 bar.

The planned activity includes:

• construction of gas pipeline DN 700/75 bar
• laying the optical communication system with the associated optical cable that is laid into one of the two protective PEHD pipes that are laid along the gas pipeline, while the other pipe is a spare one
• location of the launching / receiving scraper station DN 800 of the new gas pipeline and block station DN 700 within the existing gas node PČ Zabok MRČ Zabok
• expansion of the existing BIS Jakovlje, within which block station DN 700 of the new gas pipeline will be located as well as a new container for monitoring and control
• construction of block station BS Ivanec DN 700 and location of a new container for monitoring and control
• expansion of the existing BIS Rakitje within which block station DN 700 of the new gas pipeline will be located as well as a new container for monitoring and control
• expansion of the existing gas node PČ Lučko where launching-receiving scraper station of the new gas pipeline will be located, as well as block station DN 700, two gas collectors DN 800, technological impurities tanks and a new container for monitoring and control
• reconstruction of the existing gas pipelines Karlovac - Lučko and Lučko - Ivanja Reka within the area of PČ Lučko with a connection to the collector via measuring lines
• reconstruction of the measuring-reduction line 75 bar/50 bar of the connecting gas pipeline DN 300/50 PČ Lučko - gas pipeline Zagreb west - east DN 500/50
• installation of parts of the cathodic protection system along the gas pipeline route.

Planned completion of construction: 2nd quarter of 2026
