The new 5,000 tonne Liebherr HLC 295000 offshore crane has collapsed while on test at Liebherr’s yard in Rostock, Germany earlier today.
The crane had only recently been installed on the offshore installation vessel Orion, which is owned by Cosco (Qidong) Offshore and due to be delivered to Belgian contractor Deme group later this month.

The crane’s twin boom and jib appears to have flipped over the rear while lifting a test load at the Liebherr yard in Rostock. We are told that the incident was caused by the failure of a wire rope during an overload test, but this has not yet been confirmed. The collapse was captured on video which you can see below.
We have now learnt that it was not a rope that failed, but the hook block - the four leg hook broke free of the neck/shaft. The sudden release of the heavy test load caused the boom to catapult back over the rear of the crane and crumple.
A brief statement from Deme said that five people suffered minor injuries, two of which were taken to hospital for further evaluation. The statement added: “The crane has suffered significant damage and the vessel will be investigated in the upcoming days and weeks”. We understand that around 120 people were working on the ship at the time.
