PN mini-submarine fleet

[syed_yusuf]

lot of proliferation of fuel cell tech has happened in civilian market ..and cars ...whether that tech can be applied to military use..? Dont know..

Efficiency of sterling is questionable in warm waters

Is fuel technology same as used by electric cars, is so can they be recharged ? Is it possible to just replace batteries and put fuel cell instead ?

I believe this is a concept proposal, and not designed or industrialized yet since there is no current customer to take the risk.

Submarine main propulsion batteries will never be replaced. This is what a Hybrid system is what you see in cars. However, the types of batteries is being evolved to increase the energy density and safety. AIP is always a third system to bring the Indiscretion rate in your favour.

What is in civilian market would need to be marinized, and then Military qualified, and then made compact enough to or a mini sub, and then rugged enough to be used and abused in the field. Maybe then.

yes..problem is that fuel cells are run by hydrogen and hydrogen is very expensive to make and even more problematic to distribute

The upsize is that its lighter than a battery thus much better range and much fesible in heavy automobiles ..

So fuel cells excellent range but expensive as you have to make hydrogen and use that to run the fuel cell ..lithium batteries very cheap as its just electricity storage

German U boats use fuel cell a 2 decades ago..now common in cars ..so technology has already proliferated enough

Turkey don't have indeginous DSRV solution and protocols yet and I agree. I'll explain below why that Turkey did not rush in this area.

Centered around the International Submarine Escape and Rescue Liaison Office (ISMERLO), an organization created in the wake of the Kursk tragedy as an international hub for information and coordination on submarine rescue, the exercises are designed to demonstrate multi-national submarine rescue co-operation and interoperability as well as share SMER related knowledge amongst worldwide partners. So this is not a restricted area, and also Pakistan is a part of these common programs. Contrary to the above, Turkey is one of the few countries in NATO, capable of deep water rescue missions. Having not yet to produce domestic DSRV solution is due to accessibility and common protocols. The development of deep-sea rescue equipment in this area is often dealt with by allied countries. Implemented by Turkey Submarine Escape and Rescue (SMER) procedures are fully NATO compatible.

TCG Alemdar( which is latest submarine rescue mother ship of TN ) is currently the one of the most modern submarine rescue mother ship in the world. These surface platform include HARDSUIT atmospheric diving suits (ADS), personnel transfer capsules (PTC), a McCann submarine rescue chamber (SRC), launch and recovery system (LARS), and a towed side-scan sonar system.

It also features transfer-under-pressure equipment, dive systems, a NATO submarine rescue system (NSRS), a US submarine rescue diving and recompression system (SRDRS) and post-modern decompression / recompression pressure chambers. A submarine ventilation system, pressurised breathing air system and HeO2 mixed gas system are also included. Two interconnected L-type SRV connectible pressure chambers are provided aboard the vessel to facilitate the housing of up to 32 survivors.

A flight deck is fitted behind the bridge structure amidships to support helicopter operations, while the aft deck features a hydraulic / telescopic crane used for deployment and recovery of rescue systems. Additionally, the MOSHIP carries one remotely-operated vehicle (ROV) and a rigid-hulled inflatable boat (RHIB), as well as two rescue boats to assist during rescue operations.

Turkey has highly specialized team ( within NATO standards ) in this field. For this reason, Turkey is continous member of major submarine rescue drills carried out under NATO. Let's examine the biggest submarine rescue exercise in recent years.

NATO Centre for Maritime Research and Experimentation (CMRE) participated for the first time in the DYNAMIC MONARCH 2017-Aksaz/Turkey exercise, bringing to the operational players a new digital underwater acoustic communications capability that may increase significantly the effectiveness of distressed submarines escape and rescue operations. (In this area many new underwater communication protocol research is being carried out in Turkey. You may find some information in previous posts of the topic.)

In total, the 2017 exercise included approximately 1,000 personnel, command and control ship TCG Gemlik, three submarines (TCG Burakreis, TCG Preveze and ESPS Tramontana), four submarine rescue ships (TCG Alemdar with Turkish and US submarine rescue chambers onboard, TCG Inebolu, ITS Anteo and SD Northern River with embarked NATO Submarine Rescue System (NSRS) operated by the United Kingdom, France and Norway), four Turkish patrol boats, four Turkish aircraft (helicopters, Maritime Patrol Aircraft and a C-130), diving teams from Canada, Italy, Poland and Turkey, Medical teams from Canada, Turkey and NSRS (France, Norway and the UK), a Submarine Parachute Assistance Group from Turkey and significant support from host nation Turkey in administration, accommodation, contracting, logistics, transportation and personnel. Nine NATO Allies participated in the exercise with equipment or personnel including Canada, France, Italy, Norway, Poland, Spain, Turkey, the United Kingdom and the United States. In addition, observers from Bangladesh, Indonesia, Japan, Pakistan, Poland, Spain, South Korea, Sweden and the United Kingdom experienced various portions of the exercise as well.

What the depth rating of the submarine rescue and transfer of the Mccan bell?

lithium batteries very cheap as its just electricity storage. So the modern fuel cell is basically really big lithium battery carried by submarine?

What the depth rating of the submarine rescue and transfer of the Mccan bell?

600 meters. Beyond that comes the hull crush depth

 

[Bilal Khan 777]

600 meters. Beyond that comes the hull crush depth

The Mccan bell is rated to 300 meters, and ROV is rated to 600 meters.

Shallow Water Attack (SWAT) Submarines are the best choice for both defense and offense purposes for Pakistan Navy. I have an eye on this thread and in due course of time will share some interesting information on the said matter (if allowed). Stay Tuned

Waiting for your interesting information.

Any update on this program? Has PN decided on their SWAT S/M?

Not Yet. Work in Progress

I believe these are only concepts, not engineering designs or under production.

First 3 are single hull concepts, last one is the export variant of the Type 041A.

Not just concepts.
