High-strength steel from German thick steel plate specialist Dillinger’s plates measuring up to 220 mm in thickness have been used for Liebherr’s largest ever heavy-duty crane HLC 295000. The steel supplied by Dillinger for the heavy-duty crane meets special requirements for yield strength, impact strength, and Z-grades, ie specific properties related to plate thickness. The HLC 295000 heavy-duty crane, which has a maximum lifting height of 175 meters, was manufactured at the Liebherr site in Rostock and installed on the Orion, a purpose-built vessel of the Belgian DEME Group. It embodies a new generation of Liebherr offshore cranes and stands for exceptional efficiency, speed and intelligent technology. The crane’s compact design makes it ideal for the offshore sector. Its base column of just 16.8 meters in diameter is unequalled on the market. Plus, a maximum load capacity of 5,000 tonnes and a jib of up to 151 meters means the HLC is capable of moving large components with precision.The heavy-duty crane is chiefly being used to lift offshore foundations and associated platforms during the dismantling of disused offshore oil and gas production facilities, as well as for the installation of the ever-growing offshore wind power components, as was recently the case at the Arcadis Ost 1 wind farm off the island of Rügen. Other steel products are also paving the way for an effective energy transition here: Steelwind Nordenham, a Dillingen Group company, supplied XXL monopiles for the wind farm; the largest ever required for such a purpose in Europe.
