Heavy lift transport specialist, Mammoet, has recently completed two contracts delivering key components for the Duqm oil refinery. The first was awarded by a local manufacturer and required the inland and ocean transport of nine LPG storage tanks, while the second was awarded by Agility Global Logistics and involved receiving and transporting various reactors.
Each of the 72m long, 11m high and 8m wide LPG tanks weighed 780 tonnes and were fabricated in Sohar. These units were loaded by 44-axle self-propelled modular trailers (SPMT) onto a barge provided by Mammoet in Sohar, bound for the Port of Duqm.
According to Mammoet the key to the success of this heavy lift operation was the precise positioning of the ro-ro ramps, an accurate ballasting plan, expert mooring, and effective sea fastening. Once off-loaded in Duqm the tanks were staged in the port’s laydown area and transported 25km to the project site, where they were positioned onto their foundations by 1600 tonnes and 1250 tonnes capacity crawler cranes working in tandem. Mammoet says that by managing the complete logistics chain, from the fabrication yard to the Duqm refinery, it was able to ensure timely and safe delivery of these key refinery components.
The Agility contract included handling a 1130 tonnes reactor measuring 33m long, 8.7m wide and 7.3m high, which was the heaviest cargo ever offloaded at the Port of Duqm. A 54-axle SPMT was used to move the heavy load to the refinery site.
The Duqm projects are amongst the first to be performed since the acquisition of ALE by Mammoet. The operations saw colleagues from both former companies combining their expertise.“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,” commented Vishal Buddhadev, General Manager of Mammoet’s Oman branch.
