Vizhinjam Breakwater: The Granite Giant

The Vizhinjam breakwater is one of India’s most ambitious coastal engineering projects. Designed to protect the harbor and nearby fishing communities, it combines strength, innovation, and efficiency.

Vizhinjam breakwater is engineered to withstand waves for over a hundred years. This massive structure, built from sturdy granite, also offers a stunning aerial view. It currently stretches 2,960 meters, with an additional 920 meters to be completed by 2028—bringing the total length to 3,880 meters. The length of the berth will also be extended.

During the monsoon season, it becomes difficult for boats to enter the fishing harbor through the harbor mouth due to strong waves. Many accidents, including boat capsizes, have occurred in the past. The breakwater is constructed close to the coast to protect fishing vessels from tides, currents, waves, and storm surges.

The breakwater has a depth of 18 to 20 meters, making it the deepest in the country. Its height is 28 meters—equivalent to a nine-storied building. The construction cost is ₹1,387 crore, fully funded by the state government. It is designed to withstand waves up to 8–9 meters in height.

Construction requires 68 lakh metric tons of granite, equivalent to approximately 2,25,000 truckloads. Of this, 60% of the granite is sourced from quarries in Kerala, while the remaining 40% comes from Tamil Nadu.

The first phase of commissioning is scheduled for May 2. The second to fourth phases will follow thereafter.

The Vizhinjam breakwater not only reinforces the coastline but also symbolizes Kerala’s commitment to maritime safety and infrastructure development. As its construction progresses, Vizhinjam is set to emerge as a key port on the global maritime map.
