Assessment of the durability of prestressed concrete sheet piles under the interference of CP gas pipeline system current, established that due to their low magnitude, these currents do not compromise the required 100-year service life of the structures. The sophisticated numerical modelling tools being developed, are important in assessing durability of concrete in underground structures. Prestressed concrete sheet piles are equipped with monitoring devices consisting of sensors such as reference electrodes. To assess the expected life of interference in terms of steel piles, the level of of interference expressed as the maximum interference current density at the entrance and exit points on the steel must also be known.
