Sarens contributed to a significant project aiming at enhancing energy efficiency in Frankfurt, Germany. This project involved the installation of two horizontal HRSG (Heat Recovery Steam Generator) boilers for our client, Duro Dakovic Montaza who were delivering for their client, Siemens Energy.

The project was located in Frankfurt am Main and started in November 2024. It is expected to be completed by the beginning of the third quarter of 2025. The primary objective was to generate additional energy by converting the heat from the gas turbine, which would otherwise be lost, into electricity. This initiative will not only boost the local economy but will also contribute to greener fuels and reduced pollution.

Sarens was selected for this project thanks to our previous successful collaborations with the client and our international expertise. The project required extensive engineering and several meetings with Duro Dakovic Montaza and Siemens Energy to finalise the use of the AC700 crane, which was chosen for its capacity and suitability for the job site conditions.

The AC700 crane, configured with a WiHi 24m, was transported from one of Sarens' depots in Poland to Frankfurt over two nights. The assembly of the crane required partial road closures due to the tight job site. Despite challenges such as transport permits taking longer than expected, the crane was successfully assembled and positioned to perform all necessary lifts within the job site's constraints.

Following the key contribution of the AC700, the LR1750 was shortlisted to complete the job. The LR1750 joined the project around the end of May 2025 and contributed to the job during 1,5 months, performing the installation of the stack of the two HRSG installations.

The project team included two crane operators, with riggers and a lifting supervisor provided by the client. The team worked diligently to ensure the project's success, overcoming logistical challenges and adhering to strict timelines.

We are proud to have been part of this transformative project that not only enhances energy efficiency but also supports the local economy and promotes sustainable practices.
