MULTIPART SERIES - PART 1
- Mazagon Dock Limited, Mumbai, an ISO 9001 : 2008 Company is one of the leading shipbuilding and offshore fabrication yards in India.
- The Yard was established in the 18th century, and over the 200 odd eventful years, has earned a reputation for quality work and established a tradition of skilled and resourceful service to the shipping world in general and the Indian Navy, Coast Guard & ONGC in particular.
- In its varied history, MDL passed through various ownerships like the P&O lines and the British India Steam Navigation Company. It was incorporated as a Public Limited Company in 1934.
- After its takeover by the Government in 1960, Mazagon Dock grew rapidly to become the premier war-shipbuilding yard in India, producing sophisticated warships for the Navy and offshore structures for the ONGC.
- It has grown from a single unit, small ship repair company, into a multi-unit and multi-product company, with significant rise in production, use of modern technology and sophistication of products.
- The company’s current portfolio of designs spans a wide range of products for both domestic and overseas clients.
- The activities at the yard are shipbuilding, submarine building, and fabrication of offshore structures. It has manufacturing facilities situated at Mumbai and Nhava.
- The yard has the capability to build warships, submarines, and merchant ships up to 30,000 Dead Weight Tons(DWT).
- It can also fabricate well head platforms, process and production platforms and jack-up rigs for oil exploration.
MDL has constructed a variety of ships both for the defence and the commercial sector.
“INS NILGIRI".
- The first modern warship to be built by the company was the Leander Class frigate “INS NILGIRI".
- Its design was obtained from the British Admiralty and the frigate itself was built in collaboration with M/s. Vickers Ltd. and M/s. Yarrow (Shipbuilders) Ltd. of U.K.
- The NILGIRI was launched in October, 1968 and commissioned in 1972.
- During the next nine years Mazagon Dock built and delivered five more frigates in this class for the Indian Navy.
- Indian Naval Ships Nilgiri, Himgiri, Udaygiri, Dunagiri, Taragiri and Vindhyagiri formed the main thrust package of the Navy in the seventies and eighties.
- As the construction of the Leander series was nearing completion, the Navy evolved a design for a new generation frigate.
- Mazagon Dock was responsible for making all production drawings in respect of the new frigate.
- Unlike the Leanders, the new frigate was Indian in concept, design and execution.
- The ship was larger than the Leander frigate with about 25% more displacement, and could embark two large helicopters.
- This new class was christened as the "GODAVARI Class", and the first ship of the series “INS GODAVARI” was launched in May 1980 and commissioned in December 1983.
- INS GANGA and INS GOMATI followed in 1985 and 1988.
- Further construction of this class of warships was entrusted to GRSE, Kolkatta, with lead yard services being provided by MDL.
Destroyer class Project-15 Delhi Class
- Construction of the destroyer class Project-15 ships powered by gas turbines was undertaken.
- These 6,700-ton mammoth destroyer class of warships were the largest ships built in this part of the world.
- The first of the class, `INS DELHI' was launched in February 1991 and commissioned in November 1997;
- the second “INS MYSORE” was commissioned in 1999.
- The third and last ship in the series "INS MUMBAI" joined the Navy in January 2001.

- The Kolkata-class (Project 15A) are a class of stealth guided-missile destroyers constructed for the Indian Navy.

- The destroyers are a follow-on of the Project 15 Delhi-class destroyers
Offshore Patrol Vessels
- Besides warships for the Navy, Mazagon Dock has also constructed a series of Offshore Patrol Vessels for the Coast Guard.
- These vessels are specialised ships for patrolling, policing, search and rescue operations in the Exclusive Economic Zone of the country.
- They are also provided with capabilities for pollution control and fire fighting and carry a helicopter on board.
- The design of these vessels was entirely evolved at Mazagon Dock.
- Seven Coast Guard Ships, INS VIKRAM, INS VIJAYA, INS VEERA, INS VARUNA, INS VAJRA, INS VIVEK and INS VIGRAHA, which today form the mainstay of the Coast Guard fleet, were built and delivered to the Indian Coast Guard between December 1983 and March 1990.
- Follow on vessels of this class have since been built at the Goa Shipyard under lead yard services from MDL.
- Mazagon Dock has also completed the construction of two series of Offshore Supply Vessels, comprising seven ships, for the ONGC.
