Wow Ibrahim, great website you created there. I don't know if this summary replicates wht you already know but since I've already compiled some data I will post it anyway.
I have a video clip somewhere of a Focke Archelis being flown off U 862 which I might be able to email you and also a photo of U-862 from a Japanese patrol boat as she sailed into Penang if that interests you?
The first U-boat to meet with Japanese forces in the Indian Ocean was U 180 in 1943 when the Indian nationalist Subhas Chandra Bose was handed over to the Japanese, but U 180 returned to Europe without reaching land.
Ironically the first German submarine to visit Singapore was in fact an Italian transport submarine in German service UIT-23 which voyaged from Sebang to Singapore sometime between July and August 1943.It was joined in August at Singapore by another former Italian boat UIT 25. The ex-Italian boats played a vital role shuttling cargo from the fighting U-boats which arrived at Penang etc to Japan.
They were harder for the Allies to intercept because their signals discipline was not as lax or predictable as the Japanese vessels. Japanese submarines were for example required to surface and report to Tokyo at midday. Unfortunately the Japanese did broadcast the expected movements of German units to Japanese controlled ports which led to several ambushes by Allied subs. UIT 24 and UIT 25 however continued a cargo shuttle from Singapore to Japan throughout the remainder of the war, 1943 - 45. U 219, U 195 and U 862 were interned by the Japanese at Selatar in 1945 when Germany surrendered.
Singapore was also a departure port for some Japanese submarines to France and arrival point for fewer which returned. Possibly some surface blockade runners may have stopped at Singapore too but these voyages tapered off through 1943.
The Germans provided 3 rotor Enigma machines to the Japanese for a joint communications cipher net, but all except 30 machines were lost in the I-29 sinking. The machines which survived were offloaded at Singapore. Their actual use is questionable. The Germans operated a radio base at Penang for U-Flotte 33 however operational orders still came from BdU Germany, not Penang.

Reason: Standardisation of the correct spelling for german U-boats with space and without hyphen: for example "U 188" - not "U-188" or "U188"
