Specific evaluation tools such as the KaRo program for assessing pigging results and the program for assessing defects in old welds incorporate the latest scientific advances. TZA uses probabilistic evaluation principles for assessing rehabilitation requirements in VNG's old lines. The approach has fundamentally changed VNG's strategies for maintaining high-pressure gas lines, meaning that - rehabilitation is limited to repairing acute defects which have been accurately assessed and located, - other defects are classified into a phased rehabilitation program based on reserve service life, - costs are reduced to the level required for reliable operation and supply, - planning confidence exists in the preparation/implementation of proposed steps, and - the reliability and technical integrity of VNG's network can be verified.
