A heavylift crane collapsed in Rostock, Germany, during load tests at the Liebherr construction yard. The incident occurred on May 2, 2020, when the crane broke off while testing a load of 5,500 tons, causing the upper half of the crane to tip over and smash onto the offshore installation vessel Orion 1.

The ship, being built by Cosco (Qidong) Offshore, was scheduled to be delivered later that month to DEME Offshore for work on the Moray East offshore wind farm in Scotland.

Four people were injured in the accident, and the crane suffered significant damage, with investigations into the damage to the crane and the vessel ongoing.

This was the second accident involving Liebherr cranes in the Rostock port within a short period.

Nothing wrong with the crane/ship's gear, it was the rigging that failed below the hook....FYI, when load testing a crane, the weight of the test load is 125% of the rated capacity as stipulated in the load chart, the load chart has an established safety
factor, hydraulic cranes have a 15% factor and a conventional lattice crane is 25% so in essence the test program exceeds capacity only by about 10-15%...there was nothing wrong with the structural integrity of the crane, it was the lifting points that failed (as it appears here)...I'd like to have seen the rigging apparatus/design

That looks expensive

At least nobody died in this one. I'm about to post the one that happened recently in Florida that killed 2.

A "load test" my foot. That looks like infrastructure sabotage

The block failed & shocked the system. What makes you think it's sabotage?
