Sarens installs tank roofs in Antwerp
Sarens successfully completed the assembly of three tank roofs at the facilities of Ivens Construction in Antwerp, Belgium.
The project, carried out under the framework agreement between the two companies, highlights the strong and longstanding collaboration between Sarens and Ivens, built on mutual trust and operational excellence.
The scope of works involved the installation of three tank roofs as the final stage of the tank assembly process. While most of the tank construction had been completed internally, the roof installation required external lifting operations.
Each roof measured approximately 10 metres in height and weighed 23 tonnes. The lifts were executed at a working radius of 17 metres within the Ivens yard, which offered sufficient space for safe and efficient operations.
For this operation, Sarens deployed a 300-tonne mobile crane configured with 96 tonnes of ballast. The crane was transported to site via standard road transport, requiring only one additional transport for the ballast.
Assembly of the crane took approximately two hours, allowing the team to maintain a highly efficient schedule. The crane remained on site for one day. A crew of three Sarens specialists executed the operation: one crane operator and two ballast truck drivers, who also supported the rigging activities. The lifting itself proceeded smoothly, with the roofs prepared externally and ready for installation upon arrival of the crane. Once hoisted into position above the tanks, the Ivens team aligned the roofs and began welding operations while the crane maintained the load. After sufficient securement to the tank shell, the lifting gear was released. The operation was described as a seamless joint effort between Sarens and Ivens, with close coordination between crane operator, rigging crew and the client’s mechanics on site.
Sarens and Ivens operate under a framework contract and maintain close working ties. This project once again demonstrated the value of that partnership, combining efficient mobilisation, precise lifting execution and strong on-site collaboration.
The client expressed satisfaction with the smooth execution of the works and the performance of the crane throughout the operation. Through projects like this, Sarens continues to deliver reliable lifting solutions that support industrial infrastructure and storage development in Belgium and beyond.
