[Unfall mit OffShore Liebherr Kran im Rostocker Hafen]

Crane failure during a load test on Deme’s new vessel Orion 1. It happened on Saturday Morning in Rostock Germany.

Some more details. [image] Liebherr: Broken Hook Cause of Orion Crane Collapse "The responsible authorities and experts unanimously agree that a broken crane hook was the cause of the accident."

It will be interesting to find out how the metallurgy tests on the failed part compares to what the certificates say.
