Episode 6 When Steel Whispers: Inside Offshore Inspection

In 1980, the Alexander L. Kielland semi-submersible capsized in the North Sea, killing 123 men. The cause? A 6mm fatigue crack in a weld that had been quietly growing since the rig's construction in 1976. Steel doesn't fail suddenly—it whispers first. But only if inspection is listening.This week I'm breaking down what offshore inspection actually is. Not just a diver with a torch, but a coordinated system of people, physics, equipment, and judgment all working to answer one question: is the steel still sound? I'll walk you through ACFM probes, magnetic particle inspection, how we read defects from the surface while divers work 100 meters down in zero visibility, and why a paperclip bent 20 times teaches you everything you need to know about fatigue.Plus: the story of a diver who claimed to have magnetic readings before I turned on the equipment, and what the difference between a 3.1U and 3.2U inspector actually means. This is the invisible layer that prevents headlines.
