The General Ports Company has officially commenced the floating, withdrawal, and installation of parts for the submerged tunnel. This operation is strategically divided into three phases to enhance precision and minimize errors in the process.
Project Manager Haider Salem provided insights on the complexity of these engineering tasks. He emphasized that the floating, withdrawal, and installation of the submerged tunnel components demand a meticulous approach, which is why the project has been segmented into three distinct phases. According to Salem, a specialized Dutch firm has been contracted to execute this work.
Salem elaborated that the first stage of flotation involves emptying the balance tanks of the ten components, facilitating their buoyancy. This is followed by a withdrawal phase that employs specialized systems designed to equalize weights and avert any abrupt movements. After the tanks are emptied, each component is transported to a temporary staging area, where all necessary logistical preparations for final installation are undertaken. These preparations include ensuring access to the shaft and defining the geographical coordinates for each piece’s designated location, alongside utilizing hydraulic arms and GBS systems. Ultimately, the process concludes with the immersion of each component in its specified position, linking it to the overall tunnel structure.
Ali Hamid, a representative of the Italian consulting firm, confirmed that the operations for burial, withdrawal, and installation were initiated following the successful examination of the concrete components within the manufacturing basin. Each concrete segment contains four balance tanks filled with water, which will be gradually emptied. This meticulous process will subsequently facilitate the withdrawal phase using specialized Winjat cables, ultimately aligning all ten components in their allocated area within the channel.
