Wagenborg Nedlift Provides Smart Lifting Solution for Salzbergen Refinery – Video

Salzbergen in Lower Saxony is home to one of the first refineries in Germany. Lamp oil and lubricants were produced there as early as 1860. Nowadays it is a technologically advanced refinery complex with modern blending, bottling and logistics facilities.

In a recent installation project six new storage tanks were installed by Wagenborg Nedlift’s Lifting specialists.

‘Carrying out lifting work on a site like this has its challenges,’ says Peter Eijffius, Senior Project Manager at Wagenborg Nedlift. ‘Over the years, various installations have been added and rebuilt, so the routes around the site are quite narrow in places. In addition, the new tank farm is located between several pipe bridges and buildings.’

‘We have also been involved in previous new build and expansion projects as well as maintenance shutdowns and that certainly helped in this case,’ continues Peter. I know the site like the back of my hand and our engineers know exactly where the crane setup locations are.

But every project is different anyway: weight, dimensions, exact location of the foundation and many other factors determine the possible options. That is why we carried out a comprehensive lifting study in close cooperation with H&R and the main contractor, Wang GmbH, in which various options were examined.

‘The six storage tanks were 34m high, weighed 42t and had a diameter of 4.3m. Our lifting study showed that the most efficient, feasible and safe solution was for the tanks to be delivered in two parts from the manufacturer. At the Salzbergen site, they could then be assembled into a single tank, which could then be placed in its entirety on foundations using two cranes.’

…we carried out a comprehensive lifting study. 

‘We developed this concept further into detailed lifting and erection plans, which served as the basis for the implementation. The 500t Demag AC 500 was used to unload and assemble the columns. It was positioned directly behind a building and had a small clearance between the building and the crane mast during lifting. After the storage tanks had been brought in and assembled, the 700t crane was mobilised as the main crane and the 500t crane as the ‘tail crane’. The main crane (type LTM 1650-8.1) was set up between two buildings, with additional ground pressure reduction measures and the erection of the 42m luffing jib. A little further away was another, slightly smaller crane with a man basket to pick up the slings at height. So we carried out the project in three phases of two storage tanks each.’

‘All in all, a challenging lifting project that went very well thanks to the good cooperation with everyone involved and the professionalism of our …engineers and operators!’ Peter Eijffius concludes.
