The challenge
The operator needed to decide between replacing or extending the life of ageing cranes, with the decision contingent on the true structural condition and the cost of modernisation.
Our approach
We carried out rope-access visual and NDT inspection of critical welds, 3D-scanned the boom and portal structures, built FE models to assess fatigue damage under historic and projected duty, and specified repairs, reinforcement and a drive and control modernisation package.
The outcome
Five of six cranes were confirmed for a ten-year life extension with defined repairs; one was recommended for replacement. The modernisation was executed with minimal berth disruption.
