Maintenance
The Asset Maintenance Department of NET4GAS has a team of employees with many years of accumulated know-how in performing repairs and installation work on the NET4GAS transmission system. It owns and operates specialised technology, which it uses to repair the transmission system and to ensure that it is always in a good operational condition.
The work carried out by the Asset Maintenance Department on the NET4GAS transmission system is concentrated on three main areas:
