Jawaharlal Nehru Port


Jawaharlal Nehru Port, underwater drilling and blasting, India | Client: Jawaharlal Nehru Port

Terramare is participating with underwater drilling and blasting in a fairway project in which the fairway of the Ports of Mumbai and Jawaharlal Nehru, located on the west coast of India, is being extended.








Project’s significance
India’s largest container port, Jawaharlal Nehru Port, is extending and deepening the fairway to accommodate larger cargo vessels. Overall, the project involves deepening and extending the fairway along a section of approximately 35 kilometres.

Project’s implementation
The fairway project is being implemented by a consortium consisting of Boskalis Smit India and Jan De Nul Dredging India. Terramare implemented underwater drilling and blasting at the location as a subcontractor. The underwater drilling and blasting project employed 25 professionals from Finland, the UK and Portugal.

Terramare’s underwater drilling and blasting work included the removal of 33,000 cubic metres of rock waste from an area of approximately 33,000 square metres. The site is located off Jawaharlal Nehru. The fairway area extended by the drilling and blasting was deepened to -14.7 metres. Terramare’s drilling towers, which had been installed on to a barge leased from a local company, were used in the drilling and blasting.

The project’s subcontracting agreement is significant for Terramare, because it represents an opening to the global business of underwater drilling and blasting.

Work stages
The contract included the refurbishment and shipping of six drilling towers, installation of the drilling towers on a barge, and underwater blasting and drilling.
