Cochin Shipyard Limited Successfully Re-fits Aircraft Carrier INS Vikramaditya
--From pib.nic.in
The Cochin Shipyard Limited dispelled doubts that CSL could repair the largest Indian aircraft carrier INS Vikramaditya, when on 5th November, 2016 the refit was completed a month ahead of schedule. This aircraft carrier was purchased from Russia and commissioned into the naval fleet in 2014.
Shri Rajesh Gopalakrishnan, General Manager (Ship Repair Division) at CSL said “Till INS Vikramaditya docked in Cochin Shipyard and water was pumped out of the dock and we had her sitting safely, there was a real concern on whether India could do it”.
INS Vikramaditya is one of the biggest ships owned by India and ever to have docked in India till date. In September, the Indian Navy, one of CSL’s biggest client, decided to dry-dock the carrier attached to its Karwar Naval Base at CSL for repairs on a contracted schedule of 70 days. It was clearly an opportunity for CSL to prove that India had the infrastructure as well as expertise for the task. This will also ensure readiness and preparedness with an indigenous capability in case of an emergency, without having to face the embarrassment of sending the ship outside the country for repairs.
To lay the concerns to rest, CSL tasked IIT Chennai to undertake a detailed dock floor strength analysis to prove that CSL dock indeed had the capacity to accommodate loads of this nature. The design of the dock blocks was done in-house thereafter by CSL to seat the Carrier in the dry-dock. Ultimately, CSL got the opportunity to demonstrate its capability to dock and repair INS Vikramaditya.
But, there was considerable planning & preparation to be done at CSL to accommodate the ship. This involved administrative, logistic and technical arrangements of a large magnitude. For one, INS Vikramaditya needed specially designed dock blocks made of plenty of hard as well as soft wood on which she could sit. (Shipyards typically go for a combination of concrete and wood to dry dock ships for repairs. But, in this case, plenty of "wholly wood" blocks were also used to address the loading concerns.) Another major cause for apprehension was whether this ship with higher draft would be able to clear the dry-dock sill without its propeller getting damaged, especially with the available water levels and tidal conditions in Kochi.
Then, there was water depth issue to tackle. The carrier needed higher water depth to enter the Kochi harbour. The entire outer channel, Ernakulam channel and harbour area, including dock mouth and berths at CSL were dredged to a depth of close to 14 Mtr.
While CSL was undertaking preparatory activities to enable the ship to dock, INS Vikramaditya had to berth at the ICTT Terminal nearby with a depth of 14.5 Mtr. This was to facilitate the ship to propel into Kochi on her own power.
The work package was contracted and scheduled for 70 days but certain operational requirements demanded significant compression of the time-frame and the ship was un-docked and taken out of the yard in 42 days.
Accolades have been pouring in for CSL from various quarters including the Indian Navy complimenting “CSL for working whole-heartedly 24X7 and for proving that not only is the dock fully suitable but also that that commitment and capability of Indians is second to none.”.
“It was all about human endeavour, team spirit, passion, nation building and Indian pride. CSL literally moved heaven and earth and burnt the midnight oil to complete the task entrusted to us by the Indian Navy and that too way ahead of schedule,” says a gleaming Madhu S Nair, the Chairman & Managing Director of Cochin Shipyard Limited.
Incidentally, all three aircraft carriers of the Indian Navy were in and around CSL for around a month during this period. First, INS Viraat, came into CSL for a short refit before its de-commissioning (which is understood is planned for early 2017). INS Vikramaditya, originally expected for refit at CSL in October 2016, was dry-docked in September 2016. It was virtually a touch and go situation for CSL as INS Vikramaditya came in close on the heels of INS Viraat. INS Viraat, was still berthed at Kochi when INS Vikramaditya came in to dry-dock at CSL. All this while, the third carrier, INS Vikrant, Indian's First Ingenuously built Aircraft Carrier was under construction at CSL, resulting in a situation where all the three aircraft carriers were in Cochin. The whole effort and its tremendous success augers well not only for India's most dynamic shipyard, the Cochin Shipyard Limited, but also for the nation as a whole.

The most interesting part of the whole article ...
I think it was strategically significant that the time frame was compressed all the more with Pakistan's bellsgrance and one aircraft carrier being decommissioned and the other under construction.
Bangladesh took delivery on Monday of its first submarines, bought from China, as it seeks to boost its naval power in the Bay of Bengal.
Bangladesh paid a reported $203 million for the two submarines, a deal that reflects the country's growing economic and defence ties with Beijing.
Armed forces spokeswoman Taposhi Rabeya said they would become part of the country's naval fleet at the beginning of next year.“This is the first ever addition of submarines in Bangladesh defence force,” she told AFP.Bangladesh has been expanding its defence capabilities in recent years, building a new airbase close to neighbouring Myanmar, opening several new military cantonments across the country and adding new frigates to its naval fleet.In 2013 the government of Prime Minister Sheikh Hasina signed a billion-dollar deal with Russia to buy fighter training jets, helicopters and anti-tank missiles.Hasina announced the plan to purchase two submarines the same year as part of her government's move to build a modern navy to defend the resource-rich Bay of Bengal.A UN tribunal has settled Bangladesh's long-standing maritime border disputes with neighbours Myanmar and India, paving the way for Dhaka to invite bids from multinational firms to explore for oil in the Bay.angladesh officials say that has ensured the country's sovereignty over 111,631 square kilometres of sea, an area nearly equal to its landmass.
The economics doesn't add up - China must have lost at least $200-300m total on those two subs, even if these were Foxtrot-era submarines. How much does each Kilo cost us from Russia?
November 14, 2016 in the Chinese shipyard Dalian Liaonan Shipyard in Lushun (formerly Port Arthur, is now included in the Dalian) took place the ceremony of transfer of Bangladesh Navy two diesel-electric submarine boats 035G project (Western designation Ming class). The ceremony was attended by the Chief of Staff (Commander) of Bangladesh Navy Admiral Mohammad Nizamuddin Ahmed. Past on the Dalian Liaonan Shipyard pre-sale repair submarines received Bangladeshi name Nabojatra and Joyjatra (the name translates roughly as "New Way" and "Victory Road"; the old rooms at the PLA Navy has not yet reported), were the first submarines Bangladeshi Navy, and should make independent transition in Bangladesh in early 2017. Handover ceremony of Bangladesh Navy acquired two of the presence of the PLA Navy diesel-electric submarine boats 035G project, received the names of Bangladeshi Nabojatra and Joyjatra. Lushun (PRC), 14/11/2016 (c) Bangladesh Navy
The purchase agreement in China two diesel-electric submarines of Project 035G from the PLA Navy was signed the Government of Bangladesh in December 2013. The cost of the agreement is 16 billion so (about $ 203.5 million), the amount allocated by the Ministry of Finance of Bangladesh in the budgets of five years - from 2013/2014 for the 2017/2018 financial years. Initially, for the receipt of submarines called the 2018-2019 year, but then the program in consultation with the Chinese side has been accelerated.
The staff of the Bangladeshi podzhvodnyh boats have passed the appropriate training course in China. On Kutabdiya island south of Chittagong with the assistance of the Chinese built the appropriate infrastructure for the deployment of both submarines.
Thus, Bangladesh joined the "club" of states possessing submarine fleet. The acquisition of "several" submarine has been identified in the approved 2010 20-year plan of development of Bangladesh Armed Forces "Force Goal 2030". Negotiations on the purchase of submarines were Bangladesh with several countries, including the very active - with the Russian side, and of "Rosoboronexport" offers Dhaka construction of two new submarines of Project 636, or the purchase of two submarines of Project 877 of the presence of the Russian Northern Fleet. However, in 2012 there were numerous reports that the government of Bangladesh is leaning to acquire submarines to China, and at one time circulated information that China offers Bangladesh to buy two submarines of Project 636 Russian-built from the PLA Navy. The apparent political and technical the dubiousness of such an option, apparently, and ultimately resulted in a decision to buy a "pure" Chinese boats 035G project.
Submarine Project 035 (the Ming) are the first boats of Chinese development and constructively represent a further development of the Soviet submarines of Project 633 (Chinese project 033). Total from 1971 to 2003 for the PLA Navy was built 21 submarine project 035. Of these, 12 boats belonged to the main production series 035G, build from 1989 to 1999. Currently, as part of the PLA Navy in the class remain Ming is believed to be nine or ten 035G submarine project boats and four boats of the last modification of the project 035V. Two boats 035G projects now transferred Bangladesh, they were removed from the PLA Navy in the spring of 2014.
They would probably train their submariners on the Ming class and would go for better sub from china , its a small good beginning for Bangladesh Navy to start their own submarine service , akin to IN buying the foxtrot in 70's
Not really. The F class was not outdated in the 70's or early 80's. They were build until 83. The romeos are a gen older than foxtrots and are only good for training.

Doesnt really matter the IN has been using Foxtrot till mid 2000 in exercise even Intl against Singapore Navy where it managed to get better off.
Submarine are dangerous weapon once you know its there you have to dedicate significant asset to find it no matter the generation specially if the crew is well trained
Induction of DRDO developed Naval Systems into Indian Navy – A Curtain Raiser
Four Naval Systems developed by DRDO will be handed over to the Indian Navy by the Defence Minister Shri Manohar Parrikar at a function, here tomorrow. Chief of the Naval Staff Admiral Sunil Lanba will formally take over the systems from the Defence Minister which include ABHAY – Compact Hull Mounted SONAR for Shallow Water Crafts, HUMSA UG – Upgrade for the HUMSA SONAR System, NACS – Near-field Acoustic Characterisation System, and AIDSS – Advanced Indigenous Distress SONAR System for submarines. Secretary, Department of Defence R&D and Chairman DRDO Dr S Christopher will be present on the occasion.
The systems have been designed and developed by NPOL, a Kochi based premier laboratory of DRDO which has outstanding contributions and achievements in the design of SONAR systems for the Indian Navy to its credit. ABHAY is an advanced Active-cum-Passive integrated SONAR system designed and developed for the smaller platforms such as shallow water crafts and coastal surveillance/patrol vessels. Designed using the latest technology in hardware architecture and advanced signal processing algorithms, the SONAR is capable of detecting, localizing, classifying and tracking sub-surface and surface targets in both its active and passive modes of operation.
The prototype of this compact SONAR ABHAY installed onboard a nominated Naval platform has successfully completed all user evaluation trials to demonstrate the features as per the Naval Staff Qualification Requirements. Indian Navy has proposed to induct this SONAR on three of the ABHAY class ships. Intensifying the command over the high seas is the HUMSA-UG that is designed for upgrading the existing HUMSA SONAR system of the Indian Naval platforms. The hardware architecture is based on the state-of-the-art open architecture processor technologies that will enable smooth upgrade of the system capabilities. This system is proposed to be installed on seven ships of three different classes of ships.
NACS determines the in-situ performance of the SONAR systems which are used to find the frequency-dependent 3-D transmission and reception characteristics of the SONAR. It is also used to measure the magnitude and phase characteristics of the SONAR transmission and reception electronics and the transducers. The NACS has been integrated with the HUMSA-NG SONAR array and proved onboard Naval platforms and this will be fitted on all frontline ships.
NPOL has also developed AIDSS, a distress SONAR that is an Emergency Sound Signaling Device which is used to indicate that a submarine is in distress and enable quick rescue and salvage. It is a life-saving alarm system designed to transmit SONAR signals of a pre-designated frequency and pulse shape in an emergency situation from a submarine for long period, so as to attract the attention of Passive SONARS of Ships or Submarines in the vicinity and all types of standard rescue vessels in operation. It is also provided with a transponder capability. With the induction of these four systems, the underwater surveillance capability of the Indian Navy will get a boost, besides providing a fillip to the quest for self-reliance in this critical area of technology.
Can this Abay be used on the WJ-FAC's? These boats are only 300 tonne but would be a good force multiplier. Wonder if WJ-FACs can carry 324 mm light torpedos.
One significant component of one of the systems have the fingerprints (and a bit of sweat and blood too) of yours truly. That was under open tender. We also recently won a 'single tender', which I can't talk about here . The fiction may at last come true to some extent

Thank you for your service!
Innovation and R&D are not easy, and the operationalization of your effort is the greatest recognition of your blood, toil, tears and sweat.

Dubbing it as ‘blatant lies’, the Navy on Friday denied the Pakistani Navy claim that it had prevented an Indian submarine from entering its territorial water.
“Indian Navy categorically denies the statement of Pakistani Navy as blatant lies,” Navy spokesperson Captain D K Sharma said.
He added that the Indian Navy did not have any under water movement in the said waters as claimed by the Pakistani Navy.
A statement issued by Pakistani Navy had claimed it has proved its vigilance and operational competence by detecting and blocking an Indian submarine from entering Pakistani waters.
‘The unsuspecting submarine was detected and localized south of Pakistani coast on November 16. Thereafter, despite submarine’s desperate efforts to escape detection, it was continuously tracked by Pakistan Navy Fleet units and pushed well clear of our waters,’ the statement had said.
‘Pakistan Navy fleet units detected the presence of Indian submarines in the southern parts of Pakistani waters...and restricted their activity,’ the statement said.
The spokesman claimed that Pakistan Navy had been successful in thwarting the efforts of the Indian submarines to keep their presence camouflaged.
“The Navy had constantly pursued the submarines and pushed them back,” he said.
“The Pakistan Navy is fully prepared to defend its borders and capable of responding to any aggression befittingly,” he added.
Commodore Tasneem Ahmed (retd), a Pakistani defence analyst, said Indian submarines would have been detected by air reconnaissance.
The Indian submarines might have been on an ‘intelligence gathering’ mission when detected by Pakistan Navy, Pakistani naval experts were quoted as saying by media reports.
the arrangement , gaps and white colour of the masts to me makes it one of the older 688 los angeles SSNs.
does not match the kilo, akula, u209 or scorpene to me. the 688 which operate in the arctic region have masts painted white sometimes with black spots on them.
Gurus ignorant pooch, I saw videos multiple times to my untrained eyes it is black and white video or some Video feed from aircraft radar which is again b/w so how come you can claim it is white and not other color. Also it could be that I should start wearing glasses I totally can assume that.
But it would be helpfulif we can do analysis on wake identification or mast identification on how it is done
According to them they 'detected' it 45 miles from their coast and not in their territorial waters. Then they 'forced' it 65 miles from their coast. How do you force a sub to do that? They pushed it?
. The fiction may at last come true to some extent
