History
Pipavav Shipyard was established as a wholly owned subsidiary of SKIL Infrastructure in 1997 at Pipavav, Gujarat. In 2005, with funding from major Indian financial institutions, the company was spun off and registered as Pipavav Shipyard Limited. Pipavav Shipyard Limited raised additional financing from a number of private equity investors in 2007. The company went public in 2009 with listings on the BSE and the NSE.

Pipavav Shipyard is the first corporate shipyard to be granted clearance to build warships and other vessels for the Indian Navy, though the initial licence limits this to up to 5 ships per year.

On March 26, 2015, the Company successfully implemented debt restructuring by raising additional debt of INR 5,500 crore resulting in total debt line in excess of INR 12,000 crore (about US$2 billion). The Company has a market capitalisation ranging between US$700 – 900 million and total enterprise value of USD 2.7 to 2.9 billion.

17.66 per cent of Pipavav was acquired by Reliance Infrastructure Limited on 5 March 2015 in a US$130 mln deal. Subsequently, Reliance Infrastructure launched an open offer to acquire additional shares to control 25.1 per cent of the Company. The open offer has been completed and Reliance Infrastructure now holds 36.5% equity in Pipavav and Anil Ambani has been appointed as the Chairman. The company was renamed to Reliance Defence and Engineering on 3 March 2016 and again renamed to Reliance Naval and Engineering Limited on 6 September 2017.

Facilities
Pipavav Shipyard is spread over . It has access to over 720 meters of exclusive waterfront. This is the largest shipyard in India.

Its dry dock is 640m length and 65m breadth, It can accommodate ships up to 400,000 tonnes DWT. Two cranes with a span of 140 meters & height of 85 meters together capable of handling up to 1200 Ton block and two Level Luffing cranes are erected to service this dry dock. To facilitate afloat fit-out and commissioning of ships, including afloat repairs, a 300–meter long quay, with the capacity for berthing on both sides, adequate draft and serviced by a Level Luffing crane. The entrance of the dry dock also has a 100-meter extension track for the Goliath cranes for unloading heavy machinery and equipment weighing up to 1200 Tons directly from ships and heavy lift barges.

Approximately 4.5 kilometres away from the dry-dock, and located on 95 hectares of land in a Special Economic Zone approved by the Government of India, a block-making facility has been set up for fabrication of hull blocks. By having located the workshops and fabrication facilities in a SEZ away from the dockyard site, it is able to reserve the maximum area of water frontage available at the shipyard site for ship assembly, offshore fabrication and ship repair activities whilst carrying out its fabrication and other similar activities through a SEZ unit. The blocks manufactured at this site are pre-outfitted to the maximum extent. This is done in the ideal working conditions offered by covered fabrication shops. When ready, the blocks are moved to the dock-side for pre-erection of mega/giga-blocks followed by lowering them on the dock floor for final assembly and vessel launching.
