3D Crane Boom Survey and Structural Integrity Analysis

CASE STUDY Challenge/objectives Following a NDT inspection on the three pedestal cranes on board the jack up rig, it was found that all three booms had surface corrosion covering over 50% of their total surface areas. A criterion set by the crane manufacturer states that if surface corrosion exceeds 50% of the total surface area of the boom, replacement is required and as a result, all three booms where condemned by the manufacturer wi
