Profile

Since the beginning of offshore technology, Liebherr has been involved in the development of appropriate cranes for offshore applications and today is the technology leader in this segment. Today, offshore is one of the most innovative and technologically demanding industry segments. The constant increase in worldwide energy demands and the development of ever more demanding sea beds go hand-in-hand with the advancement of crane technology. These demands have lead to considerable changes in the requirements and possibilities of our cranes. Besides being used on oil and gas platforms, Liebherr cranes are also used in other applications, including subsea work and installation of offshore wind turbines, for handling remote controlled underwater vehicles, or for installing pipelines and telecommunication cables offshore. Oil rig cranes Liebherr's range of crane technology includes diesel and electric drive units, explosion safe and suitable for use in temperatures to -50°C or special lifting heights to 2,000m under the sea. Liebherr has in its product palette rope luffing cranes as well as ram luffing cranes. Cranes with slew bearings or mast type cranes are also available. Liebherr offshore cranes are user-friendly and offer easy maintenance as well as reliability and quality standard. Crane management systems The one-of-a-kind crane management system, Litronic, developed by Liebherr, allows monitoring and controlling of all crane functions and supports an outlook on preventive maintenance strategies through recording load cycles and machine data. Board offshore cranes (BOS) The BOS crane is a conventional slew bearing type rope luffing crane. This type of crane is available in different sizes and lifting capacities of up to 1,200t. The maximum boom length for this crane is 100m, which is required for offshore wind park installation. The crane is suitable for both floating and fixed applications offshore. The crane prime mover is either electric-hydraulic or diesel-hydraulic. EX-proof systems are available. The hydraulic system is of a closed loop type technology with individual circuits for each crane function. Compact board offshore cranes (CBO) Lifting capacity is available up to 150t. The CBO crane is a weight-optimised crane system suitable for both floating and fixed applications offshore. This crane model is only available with an electric hydraulic power pack. Mast type cranes (MTC) The mast type crane is based on the kingpost principle and has a non-metallic slew bearing. This type of crane is available in different sizes and lifting capacities up to 150t. The crane is suitable for both floating and fixed applications offshore. The crane prime mover is either electric-hydraulic or diesel-hydraulic. EX-proof systems are available. The hydraulic system is of a closed type technology with individual circuits for each crane function. Ram luffing cranes (RL) The RL offshore crane is a compact solution for manned and unmanned installations, suitable for both floating and fixed applications. The luffing system is operated by one or two hydraulic cylinders. The crane prime mover is either electric-hydraulic or diesel-hydraulic. EX-proof systems are available. Heavy lift cranes Our fully revolving heavy lift crane provides lifting capacities of up to 2,000 metric tonnes. The MTC 78000 is the biggest heavy lift crane worldwide using conventional anti-friction bearing technology and is capable of full 360° turns. Innovation and quality Components for building a Liebherr offshore crane are only used after they have been installed in the field and have gone through an extensive qualification process. New developments concentrate on the advancement of existing systems and solutions considering market specific requirements and technological developments. With this strategy Liebherr will continue to strengthen and expand its position in the offshore sector.
