In the vast waters of the Maldives, the waters around the island and reef construction site are clear. Behind the busy construction is an upgrade action in pursuit of quality and environmental protection. In this construction, the Maldives Slavs Phase II dredging, backfilling and coastal protection project, which was undertaken by China Harbour Engineering Company Ltd. as the general contractor and implemented by the CCCC Guangzhou Dredging Co., Ltd., had a total filling volume of 5.12 million cubic meters. After completion, the project will help build the "Industrial Island" in Maldives and further improve the strategic structural development system of "main island + airport island + industrial island" in the Greater Male Economic Zone.
During the implementation of the project, the complex geographical environment of the Maldives waters, the existence of seabed reefs, ocean currents and climate change posed severe challenges to the construction equipment. Traditional hoses are often unable to withstand long-term high-intensity use. The CDSR armored hose, with its internally embedded wear-resistant steel ring design, performs well when transporting high-hardness materials. It not only effectively resists particle wear, but also significantly extends its service life. This design saves a lot of time and cost in maintenance and replacement, ensuring the efficiency of construction.
During the critical stage of filling operations, the CDSR dredging hose not only improves the operating efficiency of the dredger, but also reduces the impact of material spillage on the marine environment by optimizing the conveying structure. As the core dredger of this project, "Junyang 1" achieves efficient and low-emission operations by loading CDSR dredging hoses. Since the first batch of sand was blown out in September 2023, "Junyang 1" has successfully filled 12 islands in the past year, setting a record of sand extraction depth of more than 60 meters and repeatedly breaking construction efficiency records. Its overflow control and mud and sand loading efficiency have been greatly optimized, which not only reduces the disturbance to the marine environment but also improves resource utilization. This series of successful practices not only demonstrated the huge potential of CDSR dredging hoses in modern dredging projects, but also provided valuable experience and reference for the development of global marine engineering technology. In the future, with the application of more advanced technologies and the in-depth implementation of environmental protection concepts, we have reason to believe that similar efficient and environmentally friendly dredging operations will be more widely promoted and applied around the world.
