A salvage firm raised the stricken naval submarine INS Sindhurakshak in Mumbai harbour on Tuesday evening.

Sources say the submarine, which exploded and sank on August 14 last year killing 18 crew members, was slowly lifted from the harbour floor where it lay for nearly 10 months and placed it on a special barge. Indian naval personnel hoisted the naval ensign on the submarine.

Images look like CGI as this kind of underwater visibility isn't available even in reefs off Maldives. Seems to show visibility showing entire sub in the distance, that's several hundred meters.

[Philip]

The pic in Shiv's post is clearly a simulation,as the shape of the sail is not that of a Kilo.Perhaps from a clip explaining how the sub would be lifted out of the water.

Our respects to the sailors on board.

Ten months after mishap, INS Sindhurakshak raised out of water

June 07, 2014

Five months after salvors were appointed, the ill-fated Russian-made Kilo-class Indian Navy Submarine Sindhurakshak has been raised out of the water.

An explosion onboard Sindhurakshak on August 14 last year had resulted in the death of 18 Navy personnel. Navy officials said the submarine may not be seaworthy, even after refits.

“The salvors have lifted the submarine and it is currently resting on a pontoon and will be soon anchored on the dry dock of the Naval Dockyard,” said a Navy official. “We doubt that (if) it may be seaworthy after all the refits as fire was caused because of explosion of many missiles and torpedos and it would have damaged the hulk and the decommissioning seems to be imminent,” the official said.

Indian arm of US-based M/S Resolve Marine won the contract to salvage the submarine in January. A 160-days deadline was set for it to complete the job.

The senior Navy official also said that once the submarine is handed over to the Navy, it will be subjected to two sets of tests. “The first test is to ascertain the cause of the accident and the other to decide the nature of the work to be undertaken to make it seaworthy,” the official said.

Navy officials also said that though a Board of Inquiry was conducted and an interim report was submitted detailing out six probable causes of the accident, another study will be conducted by the same Rear-Admiral level officer who conducted the earlier inquiry.

INS Sindhurakshak brought out of water after 10 months

[suryag]

Lots of BRFites have had this question, why wasnt there an attempt to construct a wall around the submarien and pump the water out ? From the pics looks like it is in okie shape of course we havent seen the other side but looks like not all the torpedoes or missiles went out in their tubes

[amol]

It's been a year since the tragic accident. RIP, bravehearts.

Any updates on the cause of the accident?

ramana I seem to recall a report over a month ago that ruled out sabotage and pointed at human error/mishandling. Also the sub is unsalvageable.

I did read that too. SOPS error

NEW DELHI:
Explosions on board INS Sindhurakshak in August 2013 - which caused the death of 18 sailors and the vessel to sink in Mumbai harbour - happened because critical Standard Operating Procedures, or SoPs, were violated, an internal inquiry into the incident has revealed.

Speaking on condition of anonymity, senior Navy officials aware of findings of the Board of Inquiry said, "Processes were flouted when torpedoes were being loaded on the boat".

Confirming that procedures had indeed been violated, Chief of Naval Staff Admiral Robin Dhowan told NDTV, "Perhaps in not following certain procedures things could have gone wrong that led to accidents".

Submarines are highly complicated platforms and detailed Standard Operating Procedures are there for handling them. "We have found that whenever SOPs are not followed, there is room for error and that could lead to accidents," Admiral Dhowan said.

This is the first time the Indian Navy has officially ascribed a reason to what was perhaps the worst-ever accident in the submarine arm. (Read: Safety rules violation may be behind INS Sindhurakshak accident, says Russia)

The INS Sindhurakshak, a Kilo-class submarine - carried 16 warheads, a combination of Sut Torpedoes and Klub Missiles.

On August 14, the submarine was being prepared for a sortie - a dive at sea -- when a major explosion on board led to its sinking and the death of the sailors. The explosion took place in the forward compartment where the weapons bay was located. (Read: INS Sindhurakshak submarine explodes, 18 sailors feared dead)

Forensic examination of the 14 missiles and torpedoes recovered from the damaged submarine ruled out malfunction of ordnance which could have caused the explosion.

"Of the 16 warheads, two had exploded. The rest disintegrated, but didn't explode. This indicates that the warheads were stable and processes were violated during loading," said an official.

Admiral Dhowan said the incident has spurred the Navy to put in place strict remedial measures -- for instance, "rigid safety audits and examination by operational commands prior to sorties".

The Navy has also tested all other torpedoes and tube-launched missiles in other submarines of the same specification and found them to be "stable".

INS Sindhurakshak, the 9th of the 10 Kilo Class diesel-electric powered submarines, was commissioned in December 1997. It went through a mid-life upgrade between June 2010 and May 2013, which cost $80 million.

So most likely ESD when the weapons were being loaded set them off. what exactly was the SOP tha was not followed?
Usually there are plastic pads in the tubes. So most likely the weapon was loaded without the grounding straps and ESD built up.

[Austin]

Can ESD cause a weapons to explode ? And likely when loading they are without their fuse ?
Weapons today should be very stable against ESD influence

[ramana]

So all the worthies who screamed sabotage ready to eat crow?

[srin]

At the time of the explosion, there were a few questions about Hydrogen accumulation due to battery charging might have contributed. It is possible that the SOP deviation might have been related to the non-venting of hydrogen.

There was a Parrikar reply in Lok Sabha about Sindhurakahak explosion was due to torpedoes loading fire. Cant seem to find it.

Ramana it is on the main page of web site.

Sindhurakshak accident cannot be blamed on anyone: Govt

Defence Minister Manohar Parrikar, in a written reply to a question, told Rajya Sabha that the accident cannot be blamed on anyone since none of the officers or sailors present inside the submarines survived.

Board of Inquiry (BoI) has concluded that the incident onboard INS Sindhurakshak in the night of 13/14 August 2013 was an accident probably induced during the process of arming of the torpedoes.

"Since none of the officers and sailors present inside the submarine survived, it has not been possible to attribute any blame to any individual for failure or negligence, if any ,he said.

Sindhurakshak accident cannot be blamed on anyone: Govt

Last Updated: Tuesday, May 5, 2015 - 19:25

New Delhi: The government on Tuesday said the explosion onboard submarine INS Sindhurakshak in 2013 that led to the death of 18 personnel was "probably induced" during the process of arming of the torpedoes and cannot be blamed on anyone.

Defence Minister Manohar Parrikar, in a written reply to a question, told Rajya Sabha that the accident cannot be blamed on anyone since none of the officers or sailors present inside the submarines survived.

However, he said that disciplinary action against two officers in the chain of command has been initiated for individual lapses.

"Board of Inquiry (BoI) has concluded that the incident onboard INS Sindhurakshak in the night of 13/14 August 2013 was an accident probably induced during the process of arming of the torpedoes.

"Since none of the officers and sailors present inside the submarine survived, it has not been possible to attribute any blame to any individual for failure or negligence, if any," he said.

He said that lessons learnt from the reports of BoI are implemented appropriately.

Corrective steps have been taken by Naval Headquarters with extensive checks on weapon-related safety systems and audit of Standard Operating Procedures on all operational naval units, he said.

"Safety procedures and professional checks have been re-emphasised. Incidents Study and Analysis Cells have been instituted at professional schools wherein lessons learnt are incorporated into professional training. Safety Audits of various units are being regularly conducted," he said.

The INS Sindhurakshak accident is regarded as the worst submarine disaster for the Indian Navy and had led to the resignation of then Navy chief Admiral D K Joshi.

The Minister also gave details of accidents or incidents involving the Navy since 2014.

According to his figures, there were 12 accidents or incidents involving Navy vessels since January 2014.

At last some closure to the INS SindhuRakshak accident.

Most probable cause: Arming the torpedoes.
I.e. installing the fuze in the torpedo.

Note it wasn't the loading of the weapons in the tubes.

Since its a likely cause and not the cause a series of procedure updates and training has been operationalized.

Anyway in Accident theory assigning operator error is the easy way out and hall mark of poor investigation.

The BOI shows the professionalism of the Indian Navy.

The chain of command reprimands also show that they assign blame ot higher command and not the sailor working at the sharp edge of the system.

KUDOS to the IN from top Admiral to the lowest rung.


With this I would like to close the thread with respects to the dead.
