INS Sindurakshak: Indian Navy mulls over roping in Singapore firm for salva

[surya kiran]

The initial action will be to divide and seal the remaining undamaged portion(s) of the submarine into watertight compartments. Then these W/T compartments will be progressively de-watered, i.e. the water in them will be pumped out; thus restoring some amount of buoyancy and allowing the hull to re-float. Then this part of the sub will be supported by surface salvage ships/tugs and even by a floating crane if required. The hull then can be floated out of its present location to a another one; where the next stage will be undertaken.
Depending on the nature and extent of the damage; a call will be taken on whether to undertake repairs or dispose off the hull. If repairs are to be undertaken; then the hull will be taken to a Dry-Dock where the work will take place.
One very important thing that needs to be ascertained and confirmed: viz. is there any unexploded ordnance remaining inside the hull. If there is; then it needs to be rendered safe or safely disposed off. That is critical. Nobody will look forward to subsequent explosions while salvage operations are underway.

That in short, is how the next part of the salvage and recovery operations will go.

So, we can hope to get it operational, if the hull is recoverable? So, it may take a month to recover it and maybe a year to repair it. That is best case scenario?

Btw, I have a doubt, will the MoD now call for tenders to get the sub up or will they expedite the process and get an expert in immediately?

Could somebody explain the process for salvage? @Capt.Popeye @Penguin

Sub has been damaged beyond repair ....Unlikely to be viable for any repairs....
Current process to recover sub from Dockyard has three motives--To recover bodies of sailors for last rites ( that's least what we can do for families of deceased ) , to recover sub for " Post mortem " of accident ...and to clear berth space from Dockyard....you just can't keep that sub there ...

Given the extent of damage to Sub ---I have grave doubts about her viability ...It will be easier to build new sub than repair this one.

The Indian Naval Chief just said a couple of days back that they have all the resources to salvage the sub.

Now why the U-turn?

where did he say that??all I can remember is that they're trying to remove the water from sub to make the boat buoyant...

As per Admiral D K Joshi, Chief of Naval Staff (CNS) press address made at 4 pm in Mumbai, the naval divers had managed to open main hatch on the conning tower of the vessel. Though the submarine is merely three meters below the surface, the explosion and the ensuing fire had fused together the hatch on the conning tower which is the only point of access into the submarine. It took several hours for the divers to pry open the hatch and gain access. Admiral Joshi said that the divers would first create three or two water tight compartments. This would be followed by de-watering (removal of water) to make the boat buoyant and bring it to the surface.

but even if he said that,the situation changed as Navy couldn't risk the salvage operation when they couldn't still get the total pictures and as the sub is inside the harbor,we couldn't risk while there is live torpedos and missiles in there..so,Navy wants to play safe by using professional expertise..

The reporter asked him if the navy would request US help...the chief replied that the US unmanned recovery sub vehicle is used in deep sea, right now depth is 3 meters and we can do it ourselves, we are well capable, we have pumping and hoisting equipment.

well,Indian Navy is still doing that as per news report..its the salvage operation,i.e cutting the sub and other operations that IN is awarding to Singapore firm..and its not the first time..IN did same thing in the past too...what Chief said(I guess) is that IN will float the sub(without URS) and then start salvage operation..also,this company's Indian Subsidiary firm don't have required equipment..so,it'll take time..the stupid jurno interpreted it wrong..while IN didn't have the capability to perform salvage 1 years ago,how come they're an expert in that field???read this....

Sources also say that the Navy generally contracts two Singapore firms for such operations, like the previous two incidents in the past three years. But the Indian subsidiary of one of these firms has no required equipment.

The rescue workers are pumping out water from the submarine, hoping to make it refloat. While sources in the Navy hope the pumping out of the water is completed in the next 24 to 48 hours, the entire salvage operation could even take up to a month.
The salvage operation is turning out to be tricky and dangerous. Heavy duty pumps are being used to pump out the water from the submarine. The heat of the explosion has melted parts of the internal hull and access to the compartments has reduced as the submarine hatches have deformed.

INS Sindhurakshak fire: Navy lacks salvage expertise, say sources

most of the navy isn't armed with such capabilities and expertise..also,in this time,the situation is extra tricky..

The most critical factor is the Damage to the Hull and Machinery and Eqpt. Which means the nature and extent of the damage has to be known first. With the Sub bottomed, that may not be really easy to determine correctly.

Then will come the cost of the repairs as well as the Residual Life of whatever is intact. There is a term used in the Navy (as well as in the other forces) which is "Beyond Economic Repair (BER)". If the Hull is found to be BER; then it stands to reason that it will be written off and scrapped.

India with so many submarines needs to buy a salvage ship like this.

China’s Largest Deep-Sea Salvage Vessel Delivered


Shenqianhao, China’s first ship that carries a saturation diving system allowing divers to work at depths of up to 300 meters, is the nation’s most advanced submersible-support vessel, capable of completing submarine rescue and lifting missions as well as other underwater projects, according to a statement from the rescue and salvage bureau under the Ministry of Transport.

The ship was built by Wuchang Shipbuilding Industry and will be managed by Shanghai Salvage Co, which is affiliated with the bureau.

The vessel is equipped with a deep-water saturation diving system, which allows 12 divers to work in turns at a depth of 300 meters — 100 meters deeper than in the past, said Shen Hao, director of Shanghai Salvage Co. The system allows divers to live in an enclosed pressurized environment before they enter the water.

well,if you are interested,we can sent you to do that..atleast,one troll will be less in this forum..you want to blow a torpedo and missile filled submarine which is in the dock to blow up???I mean,HELL....you should be at asylum right now...coz next thing you'll want is to "Salvage" Gas Cylinder with Gas cutter...

I mean guys, let them handle what they are capable of...Let themselves to scratch their itchy back ...

Apparently he was lying through his teeth. He must be not far from being fired for the utter incompetence IN has displayed.

They are more interested in drinking alcohol and their wife swapping parties than serving the country and doing their duties. Indian Navy has got to be the most incompetent branch of the armed forces.
