In Saudi Arabia, the world’s largest Propane Dehydration plant (PDH) is taking shape, and Mammoet has played a crucial role in ensuring a smooth and safe installation of its critical components. As Saudi Arabia aims to diversify its economy, the petrochemical sector is poised for substantial growth, with several new facilities under construction.
One of the most significant projects is the Propane Dehydration plant being built by Samsung Engineering for Advanced Polyolefins Company (APOC) in Jubail Industrial City. This massive facility is set to become the world’s largest PDH plant, boosting Saudi Arabia’s propylene output by over 60%, producing more than 840,000 metric tonnes of propylene annually.
The challenges of such a project are enormous, requiring precise coordination of prefabricated components and overcoming unexpected obstacles. Mammoet proposed a comprehensive solution to streamline operations, managing everything from factory-to-foundation logistics to marine and land transport and heavy lifting.
Transporting 15 enormous pipe rack modules, weighing up to 1,900 tonnes and measuring up to 46 meters long and 33 meters high, from the UAE to Saudi Arabia was a complex task. Mammoet organized multiple voyages and optimized operations to minimize congestion.
The transportation process within Saudi Arabia involved intricate route planning, road network modifications, and permitting processes to safely deliver components, including the central process tower.
Among the 125 heavy lift operations, erecting the 129-meter-tall, 1,600-tonne product splitter was the most challenging. Mammoet used specialized equipment and a freestanding tower gantry lifting system to complete the task efficiently.
Despite unexpected challenges, such as delays in module fabrication and bridge maintenance along the transport route, Mammoet’s team demonstrated adaptability and problem-solving skills. The project is on track for completion and commissioning by 2024.
