This is comprehensive review and is reviewed by representative diesel manufacturers in Japan (KHI, MHI, MAN-Japan, JFE, Mitsui, etc) reviewed this article. [Pete comment the Japanese version is at http://sts.kahaku.go.jp/diversity/document/system/pdf/044.pdf [PDF, about 15MB] with an Abstract in English. It has a "Table 3.4.14 Main subject of submarine" covering the years 1960-1997 on page 35. As the document is dated March 2008 it predated public details of the Soryu-class.]

The relationship between KHI and MAN Diesel & Turbo is very healthy.

Anonymous located the following KHI Media Release “100th anniversary of technology partnership on diesel engines with MAN” dated October 24, 2011
 (originally in Japanese,) published at http://www.khi.co.jp/machinery/news/detail/111024.html and further translated by Pete:

Kawasaki Heavy Industries (KHI) commemorates the 100th anniversary of 1911, the year it entered into technical cooperation relationship with Germany's M.A.N. company (currently, MAN Diesel & Turbo) concerning diesel engines. This is the longest historical relationship among companies currently licensed with MAN Diesel & Turbo.

In 1911, when the first contract was signed, the steam engine was still in use for the propulsion of merchant ships and the diesel engine had not been introduced. KHI’s first president, Kojiro Matsukata [bio takes 30 seconds to download], signed a technical agreement with M.A.N. regarding diesels submarine use. Though the relationship was temporarily interrupted by the two world wars, we have revived the relationship each time and it continues up until the present day.

At the beginning of the contract, we intended the diesel engine for submarine use, but then extended the use to main propulsion engines for merchant ships, auxiliary power generation agencies, onshore power generation agencies, and power engines for diesel locomotives, etc.

Since 1980, we also manufacture turbochargers under the license of MAN. We provide various products of MAN Diesel & Turbo including 2 stroke diesels, 4 stroke diesels and turbo chargers.

KHI will continue to manufacture reliable, highly efficient and environmentally friendly diesel engines and turbochargers assisted by the strong relationship with MAN Diesel & Turbo.

What about submarines of Chile, Peru, Colombia and Canada?

Peter Coates said...

Well may you ask.

For the moment I can report that Canada's 4 x Upholder / Victorias haves no MAN diesels but "2 × Paxman Valenta 2,035 hp (1.517 MW) 1600 RPA SZ diesels (3.035 MW total)" [1].

Canada's Upholder / Victorias propulsion have probably proven as problematic-unreliable as Australia's Collins. I'm under the impression both cannot tolerate too much fuel tank salty ingestion leading to rust AND both cannot tolerate the full Start, Stop, Reverse requirements for submarines. Though such diesels do well for train-locomotive requirements...

So I believe both submarine propulsions are required to operate under many performance restrictions.

Dear Pete,
I‘m not aware of any current submarine with a direct drive shaft connection between the Diesel and the prop. So the requirement for the engine to run reversed is no longer required. Just change polarity on electric engine.

Thanks MHalblaub
