Tanker used exclusively for Macau - Hong Kong route - can carry anything
400nm enough to circle all of Hong Kong (including islands) twice.

You don't need to build civilian tankers to have oil imports.
You need fleet oilers if you want to supply fleet units far from home or if you want to get oil fast (and relatively secure).
Macau-Hong Kong is about twenty nautical miles distance.

QuoteYou don't need to build civilian tankers to have oil imports.

I was thinking this might be the case. In the case of the large tanekrs, their main purpose is to get oil fast.

QuoteMacau-Hong Kong is about twenty nautical miles distance.
I know, I meant to circle all of Hong Kong including the outer islands and mainland and investigate all the nooks and crannies, one would need about 400nm.

P3D

Why would you want to deliver from HK to Macau in such a large ship, when a single thousand-ton 9kts tanker would just suffice? Nevermind that there's not much need for oil in those quantities , yet.

man your makin me feal like P3D (no insult intended P3 you just used to be the Nay sayer) whats your use for these ships?  Realy you dont need Tankers, your fleet is mostly Coal powerd atm.  

The "Human" waste would be easier to handle actualy with storyline components, talk about using it as fertalizer (still a comon practice in some oriental countries) any bodies left from the battle would be a non issue at this point (actualy they would be mostly Swiss soldiers anyway so I might be the one to deal with them) but its bene what 5 years since the atack? in a tropical enviroment (and Hong Kong is one) in 5 years all you would have left is bones.

Your health issues would be largely clean watter for drinking, Rats, Mosquitos.  Atmepting to bring in enough fresh watter for 1mil people is a Major undertaking (think about New Orleans after the Huricane)

Fresh waste has to go somewhere, or cholera and dysentery will be your main issues. You probably won't have time for malaria, or worse, yellow fever to become your main concern unless you have the first two under control.

Your issue isn't disposing of the waste necessarily, it's keeping it out of your drinking water. If you can get it to the sea, you'll likely have a stinky mess on your hands, but at least no one will be drinking it. I don't think a ship is the most efficient way to do that though. Maybe just start with a few open sewers dumping it into Victoria Harbor.

Here's a half-decent link on the modern problems of water quality, etc. in Hong Kong: http://sc.info.gov.hk/gb/www.epd.gov.hk/epd/misc/ehk07/english/env_comp/index.htm

To me, the problems of a rapidly repopulating Hong Kong will be these (in roughly this order):

1. Water quality issues including supply of clean drinking water
2. Food supply
3. Shelter
4. Waste disposal (including whatever's left of Hong Kong from before)
5. Shelter
6. Commerce

Somebody who was around tell me: did Macau suffer too when Hong Kong was destroyed? If not, I suspect the locus of the area would have just moved there or to Guangzhou.

Tanthalas

as I remember it, Macau was spared the Bombardment.  Thats just from reading the story about it though.

No, I was told that only Shanghai and Hong Kong needed rebuilding.

>:( I don't really consider the Si Fu Kong to be that big. The other tankers are not going to be built... yet.

Quote1. Water quality issues including supply of clean drinking water
2. Food supply
3. Shelter
4. Waste disposal (including whatever's left of Hong Kong from before)
5. Shelter
6. Commerce
1. Well, I'll need to solve that.
2. So far, Hong Kong is getting food from the suplus in the region Guangdong.
3. A big tent with a few buildings so far. The director the the site (Yun) ordered that construction to begin as soon as space was made for a building.
4. Yes, that's the waste I was talking about. The majority is being dumped into the water right now.
5. See 3, you mentioned it twice.
6. So far, the government is paying the inhabitants to cleanup Hong Kong. If Hong Kong gets done, it will be Shanghai next.

I would think that "Human" waste is not all that's left. I am assuming that ruins are left behind as well, making it not so simple as just burying remains. Also, if possibe, I would like Hong Kong to not be known as a "city built on bones".  ;)


On another note: Does anyone know how long it would take to cleanup a city's ruins? Right now, I'm assuming about 3-4 yrs. (Which I know would probably be too short)

Tanthalas

Would depend on the number of people thrown at the situation, how intense the cleanup is.  actualy cleanup is the easy part (little more than hauling off the remians of the buildings and dumping them somewhere) rebuilding could take years though (especialy if you have a city plan and building code to adhear to)

No need to invest too much, rebuilding Hong Kong. Cleanup is nice, but your main commercial harbor in Canton - all in the Pearl river delta.

I suggest to move the Macau naval base to Canton (your largest city) instead, more justified than having it on an small outlying island.

Well about 0.5 mil people are cleaning up. About 0.25 mil are building new buildings. So far, the building plan quite messy.

I assumed the capital was Guangzhou :P, I can't really move the naval base... or can I? I don't know.

The first NS/MK war was  more than 10 years ago.

Hong Kong and Shanghai were destroyed in responce to the NS unwillingness to pay the due rent and incredible high fine for the use of those 2 cities.

During this war the MK transported the heavy ACM industries from Macau and rebuilded those deeper inland, what made that the coastal bombardment by NS just damaged the docks and slipways on.


The MK's fleet docterine was building short ranged vessels, all coal fired (no indiginous oil) and especialy loads and loads of 250-400 tons TBs.
Later on a few attempts were done to build longer ranged vessels and the aquiring of a part of the Russian fleet in Port Arthur gave the MK a small rag tag fleet with longer legs.

Then the civil war started....
