Integration of compact offshore cranes into wind converter platforms

Seatrium has selected Liebherr RL 2600 maritime cranes featuring remote maintenance capabilities for TenneT offshore grid infrastructure.  www.liebherr.com Liebherr and Seatrium are collaborating to deploy six weight-optimized RL 2600 luffing cranes across three unmanned 2-gigawatt wind energy converter platforms in the North Sea. This deployment addresses the technical challenges of remote equipment upkeep and limited installation space in offshore digital infrastructure. The project involves platforms IJmuiden Ver Beta, IJmuiden Ver Gamma, and Nederwiek Beta, operated by transmission system operator TenneT. Seatrium, acting as the engineering and shipyard group, integrates the mechanical systems into the platform design. Liebherr supplies the crane hardware and the modular LiMain digital maintenance system to enable shore-based monitoring and reduce physical site visits. Compact architecture and load specifications The mechanical solution relies on a cylinder-luffing design optimized for small tail radii and low overall height, which addresses the spatial constraints of modern converter platforms. Each crane provides a maximum outreach of 45 meters and a lifting capacity of up to 25 tonnes, facilitating heavy logistics and component replacement required for industrial automation and grid stability. Remote maintenance system functionality To support unmanned platform operations, the cranes utilize the LiMain system. This digital framework allows operators to execute key service tasks and diagnostics from onshore facilities via remote and partially automated functions. The system architecture is modular, permitting scalable monitoring levels depending on specific operational requirements. Lifecycle support and integration The cranes will interface with existing grid infrastructure to secure reliable power transmission. Following deployment, Liebherr Netherlands will manage the technical support and maintenance phases. This local service structure is designed to minimize response times, supply technical specialists directly, and maintain equipment uptime in harsh marine environments. "Partnering with a globally respected engineering and offshore solutions provider such as Seatrium underscores the trust placed in the quality and reliability of our Liebherr RL 2600 cranes. As offshore wind grows in significance worldwide, we are delighted that our solutions play a meaningful role in advancing a resilient and future-ready energy infrastructure," states Oliver Odebrecht, Sales Manager, General Purpose Offshore Cranes at Liebherr.
