Mammoet completes large 2-year construction project in Nigeria
With the installation of a 1,240-tonne propylene bullet, Mammoet has completed a large-scale construction project at the Dangote Refinery and Petrochemical complex in Nigeria. For two years, over 100 Mammoet engineers were on-site to transport and install hundreds of components, the heaviest weighing 3,000 tonnes.
In total, Mammoet moved 239 items (almost 85,000 tonnes) from a dedicated jetty to the construction site and installed 154 plant components (68,415 tonnes), including a 3,000-tonne regenerator and a 2,000-tonne crude column. The regenerator is the heaviest item transported over a public road in Africa to date.
The components were sourced globally and shipped to a purpose-built quay in Lagos, from where Mammoet moved the items to the construction site. Prior to installation, the components were stored temporarily on freshly paved Enviro-Mat, which is Mammoet’s solution to improve soil conditions in order to withstand heavy loads. In this case, it was deployed to provide the main crane hard stands.
Mammoet deployed conventional trailers, trucks, SPMT’s and a number of mobile and crawler cranes ranging in capacity from 250 to 1,600 tonnes. The contractor also brought two of its largest super heavy-lift ring cranes with lifting capacities up to 5,000 tonnes, the PTC 200 DS and PT 50.
