Nice project by SJR Maintenance
Amsterdam, 20 february 2020 – During an inspection of the tanks, N.W.B. Amsterdam observed that in one tank, the annular plates did not work correctly: they no longer counteracted soil subsidence as intended.
After reviewing the situation, SJR Maintenance decided to replace these annular plates using an air cushion rather than shoring them up according to the standard procedure. After the plates had been replaced and tested, the air cushions were once again removed and the tank could be taken back into operation.
