Hoisting the C3 Splitter: A Spectacular Engineering Feat

The construction site of the Egyptian Propylene and Polypropylene Company in Portside holds an eerie atmosphere as work begins. The sound of hundreds of wire cables being pulled taut and rubbing against each other in the wind is the only noise to be heard. The challenge at HAND is the hoisting of a massive thousand-ton steel structure - the C3 splitter. With only a few spectators present, the experts from Italian company Fagioli have erected a towering gantry to carry out this engineering marvel.

The process of hoisting the C3 splitter requires careful planning and considerations. The gantry is erected to pull the future C3 splitter into a vertical position from the horizontal. Factors like strong winds and the weight of the load are taken into account. A specially designed gantry and the use of tag lines hold the structure in place as it is raised to a height of a hundred and thirty meters.

The construction of the C3 splitter itself was not without challenges. Originally, the plan was to assemble it in South Korea and transport it by barge to the construction site. However, the lack of a navigation Channel made this plan impossible. Instead, the splitter was transported in six individual sections, each weighing 250 tons.

The lifting process begins with the columns. The D Ethan Iser, weighing 500 tons and measuring over 50 meters long, is the first to be lifted. A gantry is assembled to perform this task. Later, the Attention turns to the C3 splitter, which weighs a staggering thousand tons. The gantry, now a hundred and thirty meters high, is precisely balanced to hold the immense weight.

The actual lifting operation is a testament to precision and calculation. The operation takes ten hours, with six men working tirelessly to ensure the cables are properly fed onto the pulleys. Hydraulic cylinders lift the cables bit by bit, holding them in place while the next section is lifted. The entire process is carefully Supervised by Giovanni and his crew to prevent any mishaps.

Despite a minor glitch due to a miscalculation, the lifting operation resumes the next day. The C3 splitter is lifted another 10 meters and shifted to the side to be lowered onto a prepared platform. The wind poses a challenge, constantly swaying the colossal structure. However, with intense concentration and careful alignment, the bolts hold the column in place.

In the end, the C3 splitter stands tall, marking a significant milestone in the construction of the PDHPP plant in Portside. The challenges faced and overcome during the hoisting process demonstrate the ingenuity and expertise of the engineering team involved. The successful completion of this spectacular feat is a testament to human innovation in the field of construction.
