The recovery and repair of the crane that collapsed on board the ‘Orion 1 during lifting trials on May 2nd (IMN May 5th 2020, May 12th 2020) were progressing at the Liebherr facilities in Rostock, to where the crane’s auxiliary jib and the jib head have now been transferred. The company began work on getting the crane back into service in September. Steel construction work also began in September; both the 142-metre-long crane jib and parts of the A-frame needed to be remanufactured from scratch.
The dismantling of the HLC 295000 crane was going according to plan at berth 25, with recovery work on the quayside in the Port of Rostock in full swing and the jib components successfully recovered, as of November 11th, by the Solutions, Projects & Engineering at SARENS, the company undertaking the salvage of the damaged components of the crane.
In the next phase of the recovery the Orion 1 will be moved from berth 25 to berth 15 in the port of Rostock for the disassembly of the pivot piece and the A-frame. The TCC 78000 crane, which is permanently installed in the Port of Rostock, will be being used for the recovery of these large components. That is the same crane that was used to assemble the HLC 295000 on board the vessel.
The recovery work was expected to be completed by the end of 2020, while the repair project will be finished in the course of 2021.
Before the crane collapse the installation vessel was scheduled for delivery to DEME in late May and for mobilization at the Moray East offshore wind farm shortly after.
A giant crane had collapsed on May 2nd on Deme Offshore’s flagship under-construction offshore installation vessel Orion 1, which was at Liebherr’s yard in Rostock, Germany, undergoing crane load tests.
The vessel was under construction and owned by Cosco (Qidong) Offshore Co Ltd.
The accident happened during load testing of a 5,500-tonne capacity Liebherr-MCCtec Rostock HLC 295000 crane.
Liebherr said in mid-May that the responsible authorities and experts unanimously agreed that a broken crane hook was the cause of the accident.
