Beneath the turquoise waters of southern Maldives lies a massive "underwater Great Wall"—a coral reef system stretching thousands of kilometers, formed over hundreds of millions of years. As developers sought to transform this mysterious marine area into a resort paradise, these ancient reefs became the most stubborn obstacle.
HIDCSD7530 Model Cutter Suction Dredger Coral Reefs Mining in Maldives
The Challenge: Only 20% Progress in Two Years
The Maldives' state-owned infrastructure company, MTCC, had previously leased dredgers from other countries. However, due to insufficient cutter head power and incompatible teeth, the project made little headway—only 20% was completed in two years.
HIDCSD750 Designed for Hard Soil Mining in Maldives
In June 2022, MTCC visited China to inspect six dredger manufacturers. Ultimately, they chose the solution proposed by Shandong Hao Hai Dredging Equipment Co., Ltd., due to its technological advantages. HID’s custom-built dredger, equipped with a 6200-horsepower engine and a 2.6-meter diameter cutter head—the "Chinese Heart"—turned an impossible mission into reality.

In December 2024, the President of the Maldives visited the project site and praised HID’s solution for "perfectly solving the entire chain of transportation, excavation, and environmental challenges." Today, the envisioned resort island is beginning to take shape, and HID dredger has become a textbook case in global dredging engineering.
