Major leakages occurred during the last years demonstrate the risk involved with older pipeline systems in Eastern Europe and the FSU, which for the most part are not operated and maintained in accordance with nowadays safety standards.

The typical project approach to standardize the individual subsystem rather than engineering a customized approach, and unclear operating procedures are main causes for this situation.

Having little or no detailed information on condition of the individual systems makes it difficult to evaluate the risks involved. However, certain measures contribute to make a reasonable statement on the reliability of the system, to reduce the risk of environmental pollution significantly and to bring long term economic sustainability.

Using the experience gained through actual projects and with an individually well considered approach, a rehabilitation project in the FSU can be adequately assessed and carried out to ensure optimum deferred expenditure while meeting all relevant environmental and safety requirements.
