Upwards to 350,000 tons
It says "will be able to construct tankers with a displacement of up to 350 thousand tons, LNG carriers up to 250,000 cubic meters" that doesnt really makes any sense, i belive they confused here Gross tonnage/DWT and displacement, i do not really have alot of faith in journalists in general. There are no such ships that have 350.000t displacement, Gerald Ford-class aircraft carriers are somewhat around 100.000t of displacement, TI-class supertanker around 70.000t. What they mean is that 350.000t shall be max Deadweight tonnage of ships, at least that is the only thing that makes sense since even if they ment Gross tonnage those would be again some of the biggest ships ever made.
"Freighters, such as oil tankers and bulk carriers, are often measured by deadweight, measured in imperial tons or tonnes. Deadweight is the weight of freight, fuel, stores and anything else the ship can carry, right down to her cat. Oil tankers of around 500,000 tons deadweight have been built. This appears to be about the practical limit. Few ports can accommodate such ships, which may draw as much as 25 metres of water. The deadweight of a modern cruise ship is quite small, as she carries no freight and only limited fuel. Cruise ship deadweights of less than 10,000 tons are quite common." Source: pomorci.com
"The Zvezda yard will be a centerpiece in Russian industrial developments in the region. Here, few kilometers from the borders to North Korea and China, a key part of Russia’s future oil and gas industry is likely to be shaped. The new top-modern yard will be able produce the full range of oil and gas-related installations, among them up to 350.000 dwt tankers." - Source: barentsobserver.com
When i said they need dry docks that can be used to build 100.000t ships i was refering to displacement, not in DWT, carriers have immense DWT and even tho Zvezda looks promising it does not mean it will be big enough to build carriers, not that i wish it not to be capable of it, uncontrary i am looking forward to see Russian carriers being materialised, however Samsung heavy industries have for an example Dock No. 3 which is 640 meters long, 97.5 m wide, almost double compared to what Zvezda will have. While so big dry dock is not needed for carrier to be built itself, it depends alot on how much weight they can move around, cranes, profile cutters etc.
US is building their carriers in Newport News Shipbuilding company and they have couple of docks one of wich is Dock 12 that is 660m long and 76 wide and 510m long outfiting berth, Hyundai has 672m long one, Dalian Shipbuilding Industry in China 550m one, Qingdao Beihai Heavy Industries 480m one, Pipavav Shipyard in India is 640m long and can take ships up to 400.000DWT etc, etc. What i am trying to say is that improvements are good, Zvezda is getting better facilities but i am not sure if its really equipment suitable for carrier building.
I am an engineer, i like numbers and i like facts, and random saying "we can built 350.000t displacement ships" by journalist who doesnt know difference between weight and mass is of very low value to me. Also if you do not like other people expressing their doubts, opinions and ideas you should quit forums.
