In its largest heavy-duty crane to date, the HLC 295000 (Heavy Lift Crane), Liebherr has used high-strength steels from Dillinger with a thickness of up to 220 mm. The crane will be used to dismantle decommissioned offshore oil and gas production facilities. It will also be deployed to install foundations for offshore wind turbines, such as the Arcadis Ost 1 wind farm off the island of Rügen. Here, too, steel products play a crucial role in the transformation toward green energy: Steelwind Nordenham, a subsidiary of Dillinger, provided XXL monopiles for the wind farm - the largest ever installed in a wind farm in Europe.
The Dillinger steels used in the heavy-duty crane meet special requirements in terms of impact strength, yield strength and Z-grades, i.e., certain properties in the direction of plate thickness. The HLC 295000 heavy-duty crane has a maximum lifting height of 175 meters and was built at Liebherr's Rostock site. It was installed on the Belgian DEME group's specialty ship "Orion". It symbolizes a new generation of Liebherr offshore cranes and combines speed and efficiency with intelligent technology. Its compact design makes it particularly suitable for the offshore market. Another unique feature is its base column with a diameter of just 16.8 meters. Its maximum lifting capacity of 5,000 tons is an additional advantage. With its jib of up to 151, large components can be moved precisely.
The heavy-duty crane will mainly be used for dismantling offshore plants, lifting offshore foundations and installing offshore wind power components.
"Thinking ahead to tomorrow today is one of our basic principles," explains Dr. Karl-Ulrich Köhler, Dillinger's Chief Executive Officer and Chief Sales Officer. "Liebherr's HLC 295000 and Dillinger's steel are important tools for actively shaping the energy transition ourselves."
