Germany, Altbach: Heavy-lift specialist Mammoet has completed the transport and installation of a 358-ton transformer for EnBW Energie Baden-Württemberg AG at its new combined cycle gas turbine power plant in Altbach.
The transformer arrived at the site by river vessel before being temporarily stored and later delivered to the construction area. Engineers faced challenges due to restricted ground bearing capacity and limited manoeuvring space, requiring a tailored solution.
To manage the confined area in front of the transformer cell, Mammoet designed a temporary load-bearing platform to bridge the narrow foundation. This allowed the unit to be positioned safely. Once aligned, the platform was dismantled through staged jacking.
The transformer was then shifted onto rails and pulled into place with a 30-t hydraulic winch. The controlled movement ensured precision and safety despite the site’s limitations.
The installation forms part of EnBW’s wider “Fuel Switch” programme at Altbach, which involves replacing coal-fired capacity with a gas turbine plant prepared for future hydrogen use.
Handling oversized equipment such as this transformer is a key milestone in advancing the project. It highlights how customised lifting and transport methods are vital in delivering complex energy infrastructure.
