102Maritime Reporter & Engineering News The first CAL 64000-1500 Litronic, a heavy lift offshore crane developed by Liebherr-Werk Nenzing GmbH, recently was readied for operation, installed on- board Innovation, which is a vessel be- longing to HGO InfraSea Solutions,christened in Bremerhaven on September 3, 2012. Liebherr has positioned this new crane to meet the increasing demand for highperforming heavy lift cranes and strengthens its position in the offshore in- dustry. Within the last two years, eight heavy lift cranes were delivered for the heavy lift jack-up vessel market through- out the world: five of them are Liebherr products. The CAL 64000-1500 Litronic achieves a maximum lifting ca- pacity of 1,500 tons at a maximum work- ing radius of 31.5 m. Even at a working radius of almost 46 m the crane is still ca-pable of lifting 1,000 t. The boom length is 105 m and the deadweight of the craneis 1,500 t. Another fascinating feature is the lifting height of over 120 m above deck. A special component of the heavy lift crane is its slewing ring with an outer diameter of 13 m and an inner diameterof 11 m. The crane is so large and so heavy, that it required its own special planning for production, transport and in-stallation. First, the company?s own pro- duction facilities at Liebherr-MCCtec Rostock GmbH had to be adapted. For example, the clearance heights and widths in the workshops and on internal site roads had to be enlarged. Then the crane was transported to Poland in sev- eral parts weighing up to 600 tons each.Final assembly took place at the CristShipyard in Gdynia. The crane is designed as ?CraneAround the Leg,? ? a design that, despite the crane?s enormous size it can be posi- tioned in a space-saving way and thus re- quires a relatively small obstruction area of only 12 m ? but a design demanding special installation planning. The heavy lift crane is able to rotate 360 degrees around one of the four jack-up legs of the vessel. The assembly of the crane is thus closely coordinated with the completionPRODUCT FEATURE HEAVY LIFTING Heavy LiftersA key market sector for maritime business has been the burgeoning oil and gas market globally, a sector which has pushed the technical bounds on many fronts due to the increasing depths of operation. While there are many technolo- gies that work hand in hand to ensure safe, efficient operations in increasingly deep and treacherous waters, heavy lift- ing technology is central to getting the job done. The first heavy lift offshore crane, type CAL 64000 developed by Liebherr, is ready for operation. MR#11 (98-105):MR Template 11/6/2012 10:13 AM Page 102
