L&T launches Navy’s Floating Dock

Larsen & Toubro has launched a Floating Dock (FDN-2) designed and built for the Indian Navy at the company’s greenfield shipyard at Kattupalli, near Chennai. The Floating Dock was formally lowered into the waters of the Bay of Bengal. L&T was mandated by the Ministry of Defence to design and build the FDN-2 for an order value of Rs. 468 Crores. The Floating Dock will be delivered at Port Blair well within contracted schedule, reaffirming L&T’s capabilities to execute and deliver Defence projects on time using Indian design, indigenous technologies and construction skills. 

On completion of its launch at Kattupalli, FDN-2 would be put through a series of harbour trials before delivery to the Navy. Once operationalised, it would enhance the technical repair infrastructure of the Navy for ships based at the Andaman & Nicobar Islands as well as for visiting Naval ships. The Floating Dock is 185 meter long and 40 meter wide, and is designed for docking Indian Naval ships and submarines of up to 8000 T displacement with draughts of up to 7 meter, during both day and night. Simultaneous docking of multiple ships, and off-center docking options are also feasible. The entire design and construction process has been progressively certified by Lloyds Register of Shipping Society and overseen by the Navy’s resident team at Kattupalli. The dock, which conforms to internationally accepted norms, incorporates a fully automated ballast control system, inducting state-of-the-art technology in its equipment.

“The main challenge faced on this project, as it would characteristically be in any first ship of a class, pertained to managing design and production activities concurrently,” elaborated Vice Admiral B. Kannan. “We have achieved a high level on this through Digital Shipbuilding technologies as well as through a focused approach of ‘getting it right first time’ duly reinforced by the rich work ethics of L&T.”

The Floating Dock has been designed as a versatile dock that can be installed either along a jetty or moored in calm waters enabling round-the-year operation. It is provided with a hauling-in system to handle a ship’s docking and undocking operations. It can also support ships berthed along its side and meet their logistics requirements.   

L&T has also been mandated by the Coast Guard to design and build seven Offshore Patrol Vessels (OPVs). Two of these OPVs are to be launched in the second half of this financial year, on schedule. In addition, L&T is also undertaking repairs and refits of Naval and Coast Guard ships regularly and delivered six refit ships (including the largest Logistics Tanker ship INS Jyoti) from its shipyard at Kattupalli, which now is focusing only on Defence orders.
