Global engineered heavy lifting solutions specialist Mammoet has showcased its logistical prowess to streamline operations for the construction of the world’s largest Propane Dehydration (PDH) plant.
Mammoet leant on its extensive experience in inland and marine transportation to lift and shift 15 pipe rack modules that measured up to 46m long, 36m high, and weighed up to 1900 tonnes. The colossal modules needed to be moved from their fabrication facility in the UAE to its destination in Saudi Arabia; by organizing six consecutive voyages and utilising its nearby yard as a laydown facility, Mammoet optimized the sequencing, reduced onsite congestion, and streamlined the operations.
Needing to transport the modules a further 26km in the kingdom of Saudi Arabia, Mammoet deployed a large fleet of transport equipment, including 180 axle lines of SPMTs, 60 conventional axles, and eight prime movers. To negotiate the 26km route from the quayside and the laydown facility to the project site, Mammoet simulated the route multiple times to determine where and how the road network would need to be modified and strengthened to support the modules’ weight.
Among the 125 individual heavy lift operations, the most difficult to erect was the 1600-tonne, 129m tall, 10m wide product splitter. To facilitate this lift, Mammoet deployed its up-to-4000-tonne custom gantry lifting system and 1250-tonne capacity CC6800 that was configured with 850 tonnes of counterweight. Throughout the lift, the CC6800 handled the tail over the splitter to keep it clear of the ground during the lift, while the 130m-tall gantry system hoisted the product splitter from the top.
The Propane Dehydration plant in Saudi Arabia will become operational in 2024, and is set to become operational by the start of 2024. The plant is being built by Samsung Engineering for Advanced Polyolefins Company in Jubail Industrial City and will produce more than 840,000 metric tonnes of propylene each year, increasing Saudi Arabia’s output by more than 60 per cent.
