The project involved the reinforcement and repair of the main breakwater of the port through the placement of 3,200 precast concrete armour units, each weighing 60 tons. These units were installed to enhance structural resilience and provide long-term protection against wave action.
The project entails the construction of one of the world’s largest breakwaters, with a total length of 7,780 meters and an aggregate placement volume exceeding 20,000,000 tons. This massive volume is distributed across a carefully engineered multi-layer system, beginning with a core layer of materials graded 0–300 kg. Two successive underwater toe layers follow, comprising materials graded 300–1,000 kg and 1,000–3,000 kg, respectively. A crushed stone filter layer has also been integrated to ensure proper internal drainage and structural stability. As part of the final armour layer, we are also responsible for the placement of concrete Xbloc units, designed to provide long-term hydraulic protection and resilience against extreme wave action. The breakwater forms a key element in the ongoing expansion of a major military facility.
The project encompassed seabed dredging to prepare the site for the 130m. submerged breakwater construction. Subsequently, the core layer was constructed to form the main structural foundation, followed by the placement of an underlayer and an armour layer to provide stability and protection against marine forces. These works ensured the durability and effectiveness of the submerged breakwater in coastal protection.
