Mammoet has successfully completed the safe delivery of two heavy and oversized columns to Gazprom Neft Moscow Refinery for the construction of its new combined Euro+ facility in Moscow. Construction of the new complex will provide additional stability in fuel supplies for Moscow into the future.
A vacuum column and an atmospheric distillation column will become part of the primary refining unit, which will be used for producing Euro-5 fuel components. Transporting the columns from their fabricators’ premises in Petrozavodsk and Volgodonsk presented a sizeable challenge. Mammoet planned and implemented a complex logistics chain involving multiple transport methods to deliver the columns safely and on time.
Each column was more than 50 m long and weighed up to 700 t. In order to facilitate their transportation, the columns were delivered in several sections. The columns met similar obstacles on their routes due to their unique dimensions and weight. The comprehensive approach that Mammoet developed included road transport up to the jetties in Petrozavodsk and Volgodonsk, water transport by barge and subsequent delivery to the Moscow Refinery site.
The vacuum column, which was 12 m in diameter, was transported in seven sections of 7 m and demanded full road closures and execution at night. The atmospheric distillation column was transported in three sections, the maximum over 30 m long. Along all land routes, Mammoet specialists turned off, elevated, and dismantled power lines and urban lighting systems to provide a safe passage through. These were swiftly reinstalled once the road was cleared of vehicles.
From the jetties, each column was loaded onto a barge and delivered by river to the berth in Besedi. Once unloaded, they were transported to site by modular trailers.
