Traditionally, Naval ships have been designed and built as per the Navy’s own design standards. However, over the past two decades, advances in the commercial field have occurred, such as lightweight, high speed ships, with modern highly responsive propulsion plants etc., which have led to classification societies becoming capable of dealing with technology being deployed in naval ships. Some leading classification societies, in collaboration with their national navies have developed special Rules for naval ships which incorporate the best of commercial and naval practises and the usage of such Rules has grown with time. Perceiving the substantial advantages to be gained in adopting specially developed Naval Rules, for building of Naval ships, the Indian Navy and IRS joined hands to develop Naval Rules in 2006.A conservative approach was followed, and in the first instance, Rules were drawn up for “non-combatant” vessels and not for major warships. These Rules were first published in 2007 and were revised in 2010, in the light of experience gained in their usage. Following the release of Rules for non-combatant vessels, the development of IRS Naval Rules for “combatant” vessels was taken up. These Rules have greater focus on the military aspects of ship design.
This development marks a significant milestone in IRS’ history and is yet another contribution to make the nation, and more specifically so, the Defence manufacturing sector, self-reliant. The Make-in-India initiative has been the raison d’etre of IRS’ existence which was established in 1975 with the active support of Ministry of Shipping to promote national maritime interests and serve as a nucleus for R&D in the shipbuilding and allied sectors.
