Our company was responsible for carrying out maintenance works at the existing piles at a container terminals.
The main working procedures for the pile maintenance works are as follows:-
- High pressure water jet cleaning to remove any marine growth, loosely adhering coating and rust scale from all exposed surface;
- Surface priming, i.e. application of petrolatum based paste;
- Wrapping of petrolatum tape spirally; and
- Installation of protective jackets.
After completing these pile maintenance works, the corrosion rate of the piles at splash zone reduces greatly and the service life of the piles could then be extended.
