Mammoet, a global leader in heavy lifting and transport, has commenced work on the construction of a new combined cycle gas turbine (CCGT) power plant in Altbach/Deizisau, Germany.
This project, led by energy company EnBW, represents a significant step toward the future use of low-CO2 or green hydrogen by the 2030s. Initially, the plant will transition from coal to gas for electricity and heat production starting in 2026, ensuring an uninterrupted energy supply to both households and industry in the region.
Securing a reliable and competent partner was critical for this project, given its importance in maintaining continuous energy supply during the transition. Mammoet was selected due to its tailored engineering concept, comprehensive studies, and proven experience in power plant construction. The company had previously demonstrated its expertise in dismantling Block 1 of the EnBW Neckarwestheim nuclear power plant, further solidifying its suitability for this significant undertaking.
Mammoet’s service package for the project includes just-in-time delivery, handling and unloading of components, interim storage, and the installation of key elements such as Heat Recovery Steam Generator (HRSG) modules, generators, turbines, and transformers.
Andreas Franzke, Sales Manager & Segment Lead Power at Mammoet in Germany, highlighted the innovative approach taken: “A completely new concept has been developed in close cooperation with the client and our project team. This means a secure energy supply, fewer interfaces, and smooth processes on the construction site.”
To further streamline the construction process, Mammoet recommended the construction of a separate temporary jetty. This initiative ensures that the power plant’s existing fuel loading point remains unburdened during the unloading of materials for the construction site.
Heavy lifting operations will be managed by a 1,350-tonne crawler crane, which will handle all unloading and installation tasks efficiently and safely from a single location. Additionally, Self-Propelled Modular Transporters (SPMTs), a customized gantry system, and other specialised equipment will be employed to ensure precision and safety throughout the project.
“We are very pleased to be involved in this important construction project, which is part of the energy transition in Baden-Württemberg. It is a significant step into the future of using green hydrogen in facilities in Germany and beyond,” said Andreas Franzke.
The Mammoet team will carry out this work on behalf of the Sener Bonatti joint venture, contributing to a project that marks a significant advancement in Germany’s energy transition efforts.
