The arrival of this large pipeline, measuring 2.5 meters in diameter and 10 centimeters in thickness, represents a crucial step forward for the project of the new brine discharge and water intake system for the municipal desalination plant. This project is being developed by a joint venture of several companies in the sector.
The transportation of the pipeline, divided into three large sections, was a complex and pioneering operation in Spain. It was towed by the vessel Chelly-N from Norway, crossing the North Sea, the English Channel, and the Atlantic, until it reached the Mediterranean via the Strait of Gibraltar.
“"Its transport was in itself a singular operation."
This infrastructure will connect the new water intake system with the desalination plant, replacing an older, smaller diameter intake. The new pipeline, which will be installed at a depth of -30 meters, is expected to increase capacity and ensure optimal flow, as well as offer greater durability and corrosion resistance.
The offshore installation process is one of the most delicate phases of the project, involving initial ballasting of the pipes, their towing by a pontoon, and controlled anchoring with the help of divers to fit them into a previously dredged trench. This operation involves specialized vessels and a team of about twenty people.
“"It allows for increased capacity and ensures optimal flow, in addition to offering greater durability and corrosion resistance."
Currently, efforts are focused on the construction of the connection chamber, a large structure where the new pipelines will converge with the existing ones. This progress will provide the desalination plant with its own, more efficient, and sustainable system, strengthening the water supply for both human consumption and irrigation in the area.
