Mammoet has successfully completed the lifting of natural gas/hydrogen combined cycle gas turbines (CCGTs) and other components for a new power plant in Altbach/Deizisau, Germany, commissioned by EnBW. The project faced challenges due to the size of the CCGT units and the need to keep an adjacent coal-fired power plant operational.

A just-in-time delivery plan was implemented to manage transportation and storage of the heavy modules, which were shipped by sea from Schiedam. A temporary jetty was constructed to facilitate continuous crane operations.

The project involved lifting 15 HRSG (heat recovery steam generator) modules, each weighing between 80 and 250 tonnes, using multiple cranes. Additionally, six prefabricated stack modules, weighing up to 95 tonnes and measuring 18 metres, were lifted onto a support structure. The CCGT units required precise leveling through the use of strand jacks integrated into the crane rigging.
