Several months of construction work were saved by Mammoet Russia on a petrochemical project in Belarus, the company said.

Smart engineering and unique equipment were key factors, Mammoet Russia said.

The project included transport and installation of a pair of 450 tonne coke drums and preassembled metal structures for the project to construct a delayed coker unit at JSC Naftan in Novopolotsk. The last piece of the metal structure has now been assembled by Mammoet Russia. It took the plant to a record height of 113 metres. The heaviest piece of the structural elements weighed 365 tonnes. To lift them at the required radius Mammoet chose its 1,600 tonne capacity PTC 35 DS heavy lift ring crane with a reach of 120 m.

A small footprint was needed to allow it to work well within the limited area on-site and to use the available space as efficiently as possible, Mammoet said. Increasing the size and weight of the lifts reduced the number of cycles to nine and the project schedule as a whole was reduced by “several months”, mammoet said.

OJSC Naftan is a large petrochemical complex where products include fuel, lubricating oil, bitumen and aromatic hydrocarbons. The expansion programme has been running since 2011. It will raise refining output to 12 million tonnes a year and increases refining depth to 92%, Mammoet said.
