Mammoet completes heavy lifting project

The global leader in engineered heavy lifting and transport has also recently been awarded two contracts crucial to the success of Duqm oil refinery in Oman

August 2020

Mammoet, a global leader in engineered heavy lifting and transport, has completed a heavy lifting and transport project for the world’s largest single-train petroleum refinery in Nigeria.

With the final 1,240-tonne propylene mounded bullet installed at Dangote Petroleum Refinery and Petrochemical complex in Nigeria, Mammoet is demobilising equipment it has deployed there over the past two years. This concludes another successful project completed safely and delivered on time, the company said in a statement.

Mammoet was contracted to assist in the construction of the refinery in 2018. The scope consisted of receiving, inland transport, on site lifting and installation of hundreds of refinery components. Sourced globally and consisting of multiple shipments, these components were delivered to the purpose-built Dangote Quay Lekki in Lagos. They were then transported to the project site. Prior to installation, the components were stored temporarily on freshly paved Enviro-Mat; Mammoet’s innovative and sustainable solution for native soil improvement, which was deployed to provide the main crane hard stands.

To optimise the construction process and schedule and ensure the highest levels of construction uptime, Mammoet has drawn on its diverse fleet of heavy lifting and transport equipment. This has included 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 a 3,000t 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 adhering to the strictest safety standards - ensuring transportation and installation activities were efficiently scheduled and safely executed. Precise planning and thorough coordination were crucial to minimize delays and additional costs, maximizing the project’s efficiency.

During the project, Mammoet and its partner in Nigeria - Northridge Engineering, contributed to the local community by ensuring that the operations created value and opportunities by supporting local employment, training and encouraging local businesses to be part of the supply chain. 54 local employees were crucial to this work, covering a range of skills including SPMT operators, crane riggers and drivers. Mammoet also subcontracted work to 43 Nigerian businesses throughout its two years on site.

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.”

“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 realizing 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.” he added.

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.


Wins contracts for Duqm

Earlier, the global leader in engineered heavy lifting and transport, was awarded two contracts for Duqm oil refinery, a strategic investment for Oman that forms the cornerstone of the Duqm Special Economic Zone.

The development occupies more than 2,000 acres and, when completed, will have the capacity to process approximately 230,000 barrels of crude oil per day. It will produce high-quality products, such as diesel, jet fuel, naphtha and LPG, in compliance with global operational and safety standards.

The first contract came from a local manufacturer, involving the inland and sea transport of nine LPG storage tanks (bullets) for EPC-2 Offsite and Utilities scope of the project.

The second contract was awarded by Agility Global Logistics (Agility) and comprises receiving and transport of various reactors.

Each 780-tonne bullet fabricated at a local fabrication facility in Sohar, measured 72 m long, 11 m high and 8 m wide, and was loaded-out by 44 axle lines of self-propelled modular trailers (SPMT) onto a barge provided by Mammoet in Sohar, bound for the Port of Duqm. Precision positioning of the RoRo ramps, an accurate ballasting plan, expert mooring and sea fastening ensured successful load-outs.

On arrival at the Port of Duqm, the bullets were safely loaded-in, staged in the port’s laydown area and transported 25 km to the project site. Once at the refinery, the bullets were successfully positioned onto their foundations by 1,600-tonne and 1,250-tonne capacity crawler cranes working in tandem. By managing the complete logistics chain from the fabrication yard to the Duqm refinery, Mammoet was able to ensure timely and safe delivery of the bullets.

The Agility contract was an essential component of the Tecnicas Reunidas’ Process Unit scope of the project. This included handling a 1,130-tonne reactor measuring 33 m long, 8.7 m wide and 7.3 m high, which was the heaviest cargo ever loaded-in at the Port of Duqm. All the reactors Agility handled have been received successfully and safely delivered to the project site using 54 axle lines of SPMT.

Additionally, 10 hydraulic cranes and three crawler cranes have been engaged at Duqm refinery to support other subcontractors on site.

This is one of the first projects performed since the acquisition of ALE by Mammoet, and has seen colleagues from both former companies combining their expertise to deliver the best possible service.

“We are delighted to have successfully completed our scope for the Duqm refinery. The close collaboration of the entire project team, including our clients, the Port of Duqm and the local authorities, enabled us to successfully deliver all key equipment safely and within the deadlines set,” said Vishal Buddhadev, General Manager of Mammoet’s Oman branch.
