Tauranga Bridge Marina

‘Prolan’ was commissioned to solve major rust corrosion problems at the ‘Tauranga bridge marina -NZ’, where the ends of the bolts holding the marina walkway to the pontoons were rusting away after a 5yr period. Maintenance of approximately 50000 fittings on the piers became a major issue because of the time wasted trying to remove the seized nuts. The rate at which the corrosion occurred also highlighted the short lifespan that could be expected from the original system. Eventually the nut would rust completely away allowing the pontoon to break free and become unsafe.
