Areas of application

Offshore wind

Offshore wind is one of the fundamental pillars of our future energy production. Liebherr's offshore cranes play a “load-bearing” role in the construction, maintenance and repair as well as the possible repowering or later dismantling of foundations, wind turbines, transformer and converter stations.

Oil and gas

Liebherr offshore cranes are deployed for the assembly, repair and supply of oil and gas extraction systems. The performance capacity, size and also the way the cranes are set-up varies according to the respective requirements profile.

Heavy duty load

Heavy duty deployment, such as operations involving the erection of wind parks or the assembly of oil rigs, require the highest level of precision and safety. Liebherr offshore cranes are designed especially for these challenging tasks.

Decommissioning

As the offshore industry phases out aging infrastructure, a growing need emerges for safe, efficient decommissioning of abandoned platforms and equipment. Offshore cranes like the BOS-series are critical enablers in this process, handling heavy lifts and complex removals with precision. BOS cranes combining exceptional load capacity, advanced safety features, and reliable operation in harsh marine environments, ensuring smooth, cost-effective projects.

Crane replacements

In focusing on innovative solutions while tackling the challenges of upgrading an outdated crane installation, Liebherr and its equipment stand out with precision and efficiency. The BOS series from Liebherr has all these essential characteristics when it comes to replacing outdated offshore systems.
