Mammoet was contracted to support the construction of the Dangote Petroleum Refinery and Petrochemical complex in Nigeria back in 2018. The scope consisted of inland transport, receiving and on-site lifting and installation of hundreds of refinery components.
The globally sourced components were delivered to the purpose-built Dangote Quay Lekki in Lagos before being transported to the project site. Prior to installation, the components were stored temporarily on freshly paved Enviro-Mat; Mammoets’ solution for native soil improvement, which was deployed to provide the main crane hard stands.
For the construction process, Mammoet used its diverse fleet of heavy lifting and transport equipment, including conventional trailers and trucks, SPMTs, plus mobile and crawler cranes ranging in capacity from 250t to 1,600t.
In addition, Mammoet brought two of its largest super heavy lift ring cranes with lifting capacities up to 5,000t – the PTC 200 DS and PT 50 – to bring maximum efficiencies to the execution of the project. Their lifting capacity, combined with a long reach and a small footprint, enabled more efficient approaches to lifting and installing heavy and oversized components, such as a3,000t regenerator – the heaviest item ever transported over a public road in Africa and a 2,000t crude column – the largest crude column in the world.
Throughout the duration of the project Mammoet transported 239 items from the jetty to site, with a combined weight of 84,905t, and installed 154 items with a combined weight of 68,415t.
Over 100 Mammoet professionals worked on this project for around two years. Paul van Gelder, CEO Mammoet commented: “We are very honored that the Dangote Group entrusted us with the entire heavy lifting and transport scope for one of the most significant projects in Nigeria and the West Africa region.”
With the final 1,240t propylene mounded bullet installed, Mammoet is now demobilizing equipment it has deployed there over the past two years.
Dangote refinery is a 650,000 barrels per day (bpd) integrated refinery and petrochemical project under construction in the Lekki Free Zone near Lagos, Nigeria. It will be Africa’s biggest petroleum refinery and the world’s biggest single-train facility. Once onstream, the refinery will increase the country’s oil exports and reduce its reliance on imports of petroleum products, thereby boosting economic growth in Nigeria and generating thousands of jobs.
