On 19 May 2025, Liebherr announced that the HSI consortium (HSM Offshore Energy, Smulders and Iv-Offshore & Energy) had procured three Liebherr RL 900 offshore cranes for 50Hertz offshore grid connection projects, including one permanent platform crane for the Jasmund offshore substation on Ostwind 3. The RL 900 is a ram-luffing offshore crane designed for offshore platform duty, equipped with Liebherr's LiMain digital maintenance system. Deliveries scheduled for 2025. Liebherr is a sub-supplier to the HSI OSS EPCIC consortium (client_organisation_id on each JV member) rather than a direct 50Hertz contractor.
