Italy 2026
ECOACCIAIO Srl used the Nordweld system for the construction of 2 biogas tanks close to Bologna, Italy. The main challenge of the investment was the very limited access to the work area, which required adapting the tank erection process to the local site conditions.
Technical parameters of the tanks
Client: ECOACCIAIO Srl
Project number: 26012/01/02
Location: near Bologna, Italy
Facility: 2 biogas tanks
Diameter: 24 m
Height: 17 m
Roof and first course: stainless steel 304
Shell and bottom: carbon steel 273
The investment scope included the construction of 2 tanks with a diameter of 24 m and a height of 17 m. The roof and the first course were made of stainless steel 304, while the shell and bottom plates were made of carbon steel 273.
Restricted site access as the main project challenge
The biggest limitation on the construction site was restricted access to the erection area. In such conditions, standard logistics for plate feeding and the progress of successive construction stages can significantly hinder work organization.
To adapt the tank erection process to the available site conditions, the Nordweld system was used, allowing the tank to rotate during assembly. This enabled plates to be fed from one fixed point, eliminating the need to reorganize work around the entire tank circumference. This solution simplified logistics and ensured continuous work despite limited workspace.
Roof erection using the rotation system for the shoring tower
During the roof construction phase, the rotation system for the shoring tower was used. This solution allowed the roof assembly to be carried out in a controlled and efficient manner despite very limited access to the tank. The system improved roof work organization and minimized the impact of site constraints on project execution.
This project confirms the effectiveness of Nordweld technology in locations where access to the tank is significantly restricted. The use of the rotating tank system and the roof erection solution enabled efficient tank construction in challenging assembly conditions.
