L’incendie du sous-marin indien INS Sindhuratna a commencé sur le pont des postes d’équipage

L’incendie — et la fumée qu’il a dégagé — qui a touché le sous-marin indien INS Sindhuratna s’est déclaré sur le pont des postes d’équipage, et non dans les locaux batteries du sous-marin, a déclaré mardi le ministère de la défense.


C’est la conclusion d’une enquête préliminaire sur l’incendie tirée par une commission d’enquête dirigée par un vice-amiral.


Après le retour du sous-marin dans le port de Mumbai, une autre équipe spécialisée de l’état-major local a aussi menée une enquête.


Deux officiers, le Lt. Commander Kapish Muwal et le Lt. Commander Manoranjan autres sous-mariniers ont été blessés. A la suite de l’incendie, le chef d’état-major de la marine, l’amiral D K Joshi, a démissioné.


« Suite à l’inspection préliminaire du 3è compartiment, le lieu probable où s’est déclaré l’incendie est sur le pont des postes d’équipage, un pont au-dessus du local batterie. Certains câbles électriques présentent des brûlures ou sont endommagés dans cette zone, » explique le ministère.


Cependant, la cause de l’incendie, et son point de départ, doivent être déterminés de façon précise par la commission d’enquête.


Les sous-marins de la classe Kilo (Sindhughosh pour la marine indienne) sont équipés de 240 éléments de batteries, également répartis entre 2 locaux, avant et arrière. Les batteries actuellement installées sur l’INS Sindhuratna ont subis environ 113 cycles [1] à ce jour sur un maximum de 200.


Une inspection préliminaire des locaux batterie, et des batteries qui s’y trouvent, n’a révélé ni dommage, ni signe montrant que l’incendie aurait pu y démarrer.

Problem batteries likely cause of fatal Indian navy fire: reports


Feb 28, 2014 Spacewar.com (AFP)


Mumbai - Malfunctioning and ageing batteries were the likely cause of fire on an Indian submarine that left two dead this week, reports said Friday, amid warnings that the navy is "on the verge of breakdown".


Wednesday's accident on board the Russian-built INS Sindhuratna, the latest in a string of naval mishaps, left seven crew members injured, while two bodies were found after the stricken submarine docked in Mumbai on Thursday.


While the vessel had undergone a refit earlier this year, the batteries that powered it underwater had not been replaced because of contracting delays, The Hindu daily said, citing "highly placed navy sources".


The newspaper said hydrogen leaking from the batteries was thought to have caused the explosion.


Admiral D.K. Joshi, the chief of naval staff, announced Wednesday night he was standing down to take "moral responsibility" for the recent run of recent naval accidents.


The most deadly of these happened last August, when 18 sailors were killed as the fully-armed submarine INS Sindhurakshak exploded in flames and sank in a military shipyard in Mumbai.


"India's military is, literally, on the verge of breakdown," said an editorial in The Hindu, adding that "acquisitions of desperately needed armour and artillery systems have been endlessly delayed".


The Times of India, which also reported a likely battery malfunction, said in an editorial that "poor maintenance of submarines and warships is crippling India's navy".


It said 12 mishaps involving submarines and warships over the last seven months "may also severely impair India's ambitions of becoming a strategic blue-water power able to operate far beyond its extensive coastline".


Various other naval accidents have been reported in recent months including a submarine running aground in Mumbai's harbour, fires on a minesweeping vessel and an aircraft carrier, and a collision between a frigate and a fishing boat.


INS Sindhuratna is a kilo-class submarine which normally operates with a crew of 53 and can sail on its own for 45 days, the navy's website says.


It had been undergoing trials off the Mumbai coast as part of a clearance process for full operations when the incident occurred.

Two officers confirmed dead in Indian submarine fire


Feb 28, 2013 - (UPI)


New Delhi  - A fire aboard the Indian submarine Sindhuratna off the coast of Mumbai killed two naval officers, officials confirmed.


The victims were identified as Lt. Cmdr. Kapish Munwal and Lt. Manoranjan Kumar.


The Russian-made Kilo-class submarine was on a routine training and inspection voyage when the fire broke out early Wednesday, engulfing the sailors' quarters in smoke, officials said.


Seven sailors were airlifted to the naval Ashwini Hospital in Mumbai, suffering from smoke inhalation.


The bodies of Munwal and Kumar were found by an inspection crew, which boarded the Sindhuratna after it was towed into Mumbai harbor Thursday, the Economic Times reported.


"The two officers who were earlier declared missing have been located in the [accommodation] compartment and after examination by medical officers both the officers were declared dead," a brief message from the navy said.


Navy Chief Adm. D. K. Joshi resigned Thursday, saying he had moral responsibility for the Sindhuratna accident.


"A high-level inquiry headed by a rear admiral has been constituted to establish the cause [of all submarine incidents] and to recommend steps for continuing safe operations of submarines," a statement by the Western Naval Command said.


A source told the Times of India the Sindhuratna fire may have been triggered by a short-circuit in a battery compartment.


The Economic times reported the Sindhuratna accident was the 10th involving naval warships -- and the third submarine incident -- in the past seven months.


India has 10 Kilo-class submarines constructed in Russia's shipyards from 1985-2000, officials said last year.


Many of the submarines, including the Sindhuratna and the ill-fated 2,300-ton Sindhurakshak, underwent major refits since 1997 by the Zvezdochka shipyard in Severodvinsk near Archangel on Russia's western Arctic Ocean coast.


In August 2013, explosions ripped through the Sindhurakshak's torpedo compartment while it was berthed at the Mumbai Naval Dockyard, the vessel sank and 15 sailors and three officers were killed.
