The Dutch-Belgian consortium HSI—comprising HSM Offshore Energy, Smulders, and Iv—has selected Liebherr’s RL series cranes for three key offshore platforms currently under construction for German transmission system operator 50Hertz.
Two RL 900 ram luffing cranes will be installed on platforms OSS Darß and OSS Zingst, part of the OST-6-1 grid connection project. A third RL 900 crane is designated for the Jasmund platform, which forms part of the Ostwind 3 system. All equipment will be delivered in 2025 to construction sites in the Netherlands.
The OST-6-1 project, with a capacity of around 900 MW, is currently the most powerful offshore wind farm in the German Baltic Sea. The Jasmund platform, located 42 km northeast of Rügen island, is expected to supply 300 MW—enough electricity for approximately 260,000 households.
Liebherr’s RL 900 cranes are designed for durability and optimal performance in offshore environments, featuring a lifting capacity of up to 30 tonnes. Compact design, low construction height, and small tail radius allow for efficient operation in limited spaces.
The cranes will be equipped with Liebherr’s LiMain maintenance system—a semi-automated, digital solution enabling remote-controlled servicing. Designed to reduce on-site interventions by up to 75%, LiMain enhances cost-efficiency and autonomy for both manned and unmanned platforms.
“We are proud to contribute to the energy transition with our high-quality, locally manufactured cranes,” said Stefan Schneider, Global Application Manager at Liebherr.
