Wanted: Information on Floating Dry Docks

[Skyland]

Still investigating japanese floating docks :

3 are listed in 1929 in "Port Directory of the Principal Foreign Ports" published by US ONI.
Mitsubishi Zosen Kaisha (Nagasaki ?) :
Floating Dock No1 is 7,000 t
No2 is 12,000 t
No3 is 16,000 t (may be same as the Tsingtao one ?)

Also one 1,600 t "Governmental floating dock" is listed in 1930 for Tsushima island.

Maybe this could help http://astilleros1939.blogspot.pt/2009/ ... de_28.html


"Dique flotante" are the words you should search if you don't know Spanish.

Thank you for the link.

USS Dewey Drydock YFD-1 had a displacement of 18,500 tons
but its lift capacity was 55,000 tons
she was 501 feet long and 100 feet wide
but her draft was only 6 feet 6 inches (when empty)
a ship longer than the dry dock could be lifted - the ends were open

It could lift an entire battleship - and regularly did
the ratio between displacement and lift is probably indicated by those figures

There was a shipyard at Cebu - very small - one of only two in the Philippines (the other being at Cavite).

There is a significant dating from the mid 19th century for ocean going steel ships at Wuhan in China

Is there a built-in drydock in Hong Kong in AE ? Not in witp as far as i remember but i don't have the game on my office PC to check for AE.

Hong Kong has a rather large Repair Shipyard, Shanghai has a rather large Repair Shipyard, Singapore has a rather large Repair Shipyard, Soerabaja has a moderate sized Repair Shipyard. If a base has a Naval Shipyard, Merchant Shipyard, Repair Shipyard, they all have drydocks up the wazoo, whatever name you want to call them by. When the Japanese capture them, they all become Repair Shipyards. This is the nature of the game abstraction.

We are introducing Floating Drydocks to certain of those places that are not designated as having "shipyards" in the game, so as to model certain repair capabilities, that would not otherwise be captured, without requiring the addition of "shipyards".

If those places had "shipyards", no matter how small, a gamey player could eventually build them up to unacceptable sizes: thus Floating Drydocks. They can be sunk, they can be scuttled, they have no impact on the "shipyard" model.

Just think of them as nice little garnishes, to far away places, that will be eaten along with the main course.

The situation OTL

The two Admiralty Floating Docks (AFD) at Singapore were AFD 9 and AFD 10.

AFD 9 50,000 tons lift, 855 x 126.5 x 40 feet (length, breadth, max draft of ship). Built in 1928 in seven sections to be bolted together. It was towed out to Singapore in two parts (the article states that this was because “Its strength was insufficient to withstand ocean towage in waves in one piece.”). Each part required four tugs, and average speed was 3.3 knots.

AFD10 5,000 tons lift, 391, 63 x 17 feet (length, breadth, max draft of ship). Built in Netherlands 1924, Purchased by Admiralty from the Dutch East Indies in November 1939 and moved to Singapore.

Replacing AFD 9

According to the article “ … it was thought that repeats of AFD 9 could be built quickly in India of local steel, but with machinery and equipment from the US.” OTL AFD 23 was built at Braithwaite, Burn and Jessop in Bombay (dimensions and lift as per AFD 9), completed in March 1944, arrived Trincomalee April 1944.

By WWII there were apparently three small floating drydocks in IJN numbered 101, 102 and 103
these being different from numbers 1, 2 and 3 which were larger

All six were called, translating literally, "mobile repairs sections"
