Refinery turnaround

The challenge

Transport and lifting tasks at the refinery site

As part of the 2023 refinery overhaul, columns, tanks, heat exchangers and pipes had to be cleaned, inspected and tested at the OMV site in Schwechat. In order to complete this task efficiently and - in view of the particularly delicate environment - safely, the company once again turned to Prangl. The team of specialists drew up a logistics concept carefully tailored to the special set of circumstances.

Our solution

Prangl scores points with experience

Work on the OMV site in Schwechat is subject to very special safety guidelines. Prangl employees are always on location to perform a wide range of tasks and are therefore highly trained. Now another overhaul was on the agenda, with a total of seven weeks planned for the scheduled works. Prangl was engaged for transport on the site and for lifting between cleaning boxes - thanks to its reliability and extensive experience in the petrochemical sector.

Telescopic cranes for the longest reach

In order to ensure full coverage of the expansive washing station, the equipment had to be carefully selected. It was not only necessary to ensure the longest possible reach, economic efficiency also had to be taken into account. Six mobile cranes were chosen for the undertaking. Two 500 tonne telescopic cranes were used for the heavy lifts, plus four further cranes with 350, 250, 220 and 60 tonne lifting capacities. They were supported by two loader cranes with maximum lifting capacities of 31.6 and 40.2 metric tonnes respectively. A total of four semi-trailers were brought on site for transport to and from the washing station.

32 tonnes, 10 metres

Given the large number of equipment items, transporting these to and from the washing station was a logistical challenge. The mobile cranes lifted the delivered parts from the transporters into the cleaning boxes, where they were carefully cleaned with high pressure. The parts were subsequently lifted out again, deposited or loaded onto the transporter, which then returned them to their original location.

Unbeatable performance

Large OMV orders regularly place high demands on both personnel and machinery. After all, any delay would have had a major impact on the duration of the overhaul and as such the planned shutdown. For the first three weeks of the undertaking, work took place day and night - including on Saturdays and Sundays. And the tireless effort paid off: The Prangl team's performance was flawless, with all work completed to the customer's utmost satisfaction.
