Work has begun on the Rs 1,600-crore breakwater project associated with the Vizhinjam International Deepwater Multipurpose Seaport.

Concessionaire Adani Vizhinjam Port has designated the Grand Four Group for construction of the breakwater, which is designed to tame the waves rolling towards the port area.

Hard rocks will be deposited along a distance of 3.5 km to a width of 10 metres and a depth initially of 23.5 metres for the purpose.

The rocks are being sourced from seven quarries now, according to Sudhakar Ravu, project site manager. Strict safety measures are ensured during all stages of construction, said Noushad Khan, Managing Director, Grand Four Group.

In the subsequent phases of construction, the depth of the breakwater will increase up to to 75 metres. The project will be completed in 700 days, according to Khan.
