It is also likely that Andrews and Foreign Minister Bishop will meet Minister Nakatani and Foreign Minister Kishida in Tokyo at the annual 2+2 talks. <br /><br />Ministers Andrews and Bishop may also be attending a 2+2 meeting in Seoul with their South Korean counterparts - maybe right now in early June.<br /><br />Regards<br /><br />PetePetehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-11642159936834469602015-05-31T15:51:55.836+10:002015-05-31T15:51:55.836+10:00Hi S [at May 30, 2015 at 7:03 PM]

I now assume seafloor sensor arrays may also include radiation sensors (and submarine induced water motion sensors) in addition to all the other sensor types. <br /><br />What were you referring to regarding "German licenser"?<br /><br />Regards<br /><br />PetePetehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-9816121822940080682015-05-29T22:56:20.631+10:002015-05-29T22:56:20.631+10:00

Ministry of Defence (MOD) defined that this equipment detected radiation inside and outside of ship and alarms. MOD purchased it from company X according to MOD Business Review in FY2012. X sells monitoring system for environmental radiation measurements etc. But I don’t German licenser.<br /><br />Regards<br />S<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-71207987621917888902015-05-29T13:16:48.493+10:002015-05-29T13:16:48.493+10:00Hi S

Japan's legal ability and willingness to transfer the intellectual property of parts of the submarine is and will be a key issue in the future submarine selection.<br /><br />It is possible Germany and/or France will claim that "1.1...Electric motor, Diesel generator" originally derived from German and/or French property-inventions. This is even if the Soryu diesel is listed as "Kawasaki 12V 25/25 SB-type diesel engines" ( http://en.wikipedia.org/wiki/S%C5%8Dry%C5%AB-class_submarine )<br /><br />Re "2.1 ...Information processing subsystem" and <br />Re "2.2 Imported from USA: Harpoon missile fire control system" <br />Australia, since 2009, has also expressed interest in Tomahawk cruise missiles - fired from torpedo tubes or VLS. "Tomahawk missile fire control system" might be a future inclusion for a "SoryuAU". <br />Information processing subsystem and Fire control sytems can be seen as subsets of the broader Combat System which will, of course, heavily draw the US into technology transfer of any Soryu to Australia ("SoryuAU").<br /><br />Re "2.4...Radiation detector" could perhaps(?) include heat radiation and/or nuclear submarine radiation detection. Here is an interesting reference http://www.ultra-electronics.com/capabilities/maritime-battlespace/manned-naval-vessel-systems.aspx#Radiation-detection-and-monitoring-for-ships-and-submarines .<br /><br />I'll turn parts of this thread into separate articles on Lithium Sulphur Batteries and Soryu Intellectual Property.<br /><br />Regards<br /><br />PetePetehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-17862013058001908382015-05-29T05:12:29.269+10:002015-05-29T05:12:29.269+10:00Hi Pete

However I agree advances in LIBs and Lithium Sulphur batteries (LSBs) may make it advantageous for Australia's future subs to upgrade their batteries - maybe every 10-15 years. This may perhaps be done during "deep maintenance" when the hull is cut anyway - to replace major engine components.<br /><br />Also probably no-one knows how many years future LIBs and (and as you say) LSBs for submarine will last. Here's the Yuasa LIB for submarine site http://www.gsyuasa-lp.com/gylp-specialty-markets<br /><br />Another site with a great diagram comparing LIB vs LSB is http://www.oxisenergy.com/technology/ which explains:<br /><br />"Sulfur represents a natural cathode partner for metallic Li and, in contrast with conventional lithium-ion cells, the chemicals processes include dissolution from the anode surface during discharge and reverse lithium plating to the anode while charging. As a consequence, Lithium-Sulfur allows for a theoretical specific energy in excess of 2700Wh/kg, which is nearly 5 times higher than that of Li-ion.<br />OXIS’s next generation lithium technology platform offers the highest energy density among lithium chemistry:<br />300 Wh/kg achieved at cell level in 2014<br />400 Wh/kg forecast in 2016<br />OXIS patented chemistry provides inherent safety allowing it to meet international standards concerning shock, crush, thermal stability and short circuit...Thanks to its two key mechanisms, a ceramic lithium sulfide passivation layer and a non-flammable electrolyte, our cells can withstand extreme abuse situations such as bullet and nail penetrations with no adverse reaction."<br /><br />Regards<br /><br />PetePetehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-84124680369671333002015-05-26T22:22:35.343+10:002015-05-26T22:22:35.343+10:00Hi Pete

But as a third person, I think that 30 years’ operation is too long in a current situation. Batteries system of conventional submarine has not been changes for decades. We have used lead acid batteries. But now, the situation surrounding submarine batterie system is rapidly changing. German 212A and 214 have realized fuel cell system, and Japan has decided to adopt LIBs for next Soryu. Now, many researchers and organizations are interested to develop lithium sulfur batteries as next generation lithium based rechageable batteries which show much superior performance to LIBs and are close to market. In fact, GS Yuasa Corporation who is LIBs supplier for next Suryu announced last year that they were going to deliver the batteries sample by 2020. Current lithium sulfur batteries have some issues such as short life or safety, but they are very prominent for future submarine application. LIBs may become out of date within 30years.<br /><br />Regards<br />S<br /><br />Anonymousnoreply@blogger.com
