Mammoet completes at Dangote

After two years on site Mammoet has completed the heavy lifting and transport work at the Dangote refinery in Nigeria, Africa.

Dangote Petroleum Refinery and Petrochemical complex is the world’s largest single train petroleum refinery. Mammoet’s final job there was to install a 1,240 tonne propylene mounded bullet.

Work started on the project for the Netherlands-headquartered international heavy lift and transport specialist in 2018. Its scope was receiving, inland transport, on site lifting and installation of hundreds of refinery components. Multiple shipments from all over the world saw components delivered to the purpose-built Dangote Quay Lekki in Lagos, Nigeria.

From there they were transported to site where the components were stored temporarily on freshly paved Enviro-Mat. Mammoet said its Enviro-Mat is a solution for native soil improvement. Equipment drawn from Mammoet’s vast fleet of heavy lifting and transport equipment ranged from conventional trailers and trucks, to self propelled modular transporter and wheeled and crawler mounted mobile cranes ranging in capacity from 250 to 1,600 tonnes.

At the top of the capacity scale Mammoet also used two of its largest super heavy lift ring cranes, a 5,000 tonne PTC 200 DS and a 2,000 tonne PT 50. Choosing these facilitated more efficient approaches to lifting and installing heavy and oversized components, including a 3,000 tonne regenerator, Mammoet said. This component was claimed as the heaviest load ever transported over a public road in Africa. Another record for the refinery was a 2,000 tonne crude column, claimed as the largest crude column in the world.

In total Mammoet transported 239 loads from jetty to site. Their combined total weight was 84,905 tonnes. The 154 items installed by Mammoet on site had a combined total weight of 68,415 tonnes.

More than 100 Mammoet people worked on the project for two years. Local employees were crucial, Mammoet said, including SPMT operators, crane riggers and drivers. Work was also subcontracted to 43 Nigerian businesses.

Paul van Gelder, Mammoet CEO, said, “We are very honoured 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.

“I am very proud of what our strong, driven team have achieved. They delivered an exceptional performance. This project proves our commitment and focus to realising the most efficient and cost-effective approaches for our clients. Once again, we have demonstrated that Mammoet provides smarter, safer and stronger solutions for any heavy lifting or transport challenge, anywhere in the world.”
