V.L.C.C. - Try to build one .

Hey , Crackers !

   Funny you should post this . I have just recently acquired that particular model and another which is a Container ship !       T.B.

The ultiment in ULCC tankers was the SEAWISE GIANT, at 657,019 tons. So big that this ship could not navigate the English Channel, the Suez Canal, or the Panama Canal, because of her 81 foot displacement. A casualty of the Iran-Iraq War, she was refloated and became a storage unit at Qatar on the Persian Gulf. Broken up at Alang Gujarat, an Indian scrap yard in 2010.

That's a problem. But for training pilots, who come up onto bridges they never saw before and immediately take the conn, the simulators are pretty good. We provided a "mate" and a "helmsman" so they mainly have to show how they do with the essential manuvering and navigation. 

Any port, waterway, weather, traffic, tide and ship characteristic can be programmed. 

 

Yeah;

    Here's the rub though . I came off a ship that had been built in the 50s to this awesome place that in no way resembled my bridge ! Weird . And that was Before KIRK chairs too !         T.B. 

 

The ship computer simulator technology is amazing now. After I retired, I served as helmsman for a test for Pilot candidates in a simulator. It was just like a real bridge. 

Oh !

   You are so right .Three scary months .Thank goodness I had training Before They sent me there !  T.B.

Memory serves, there was a tanker driver school in Holland where they drove scale ships around.

Ouch. a 1300' ULCC at 1/350 is 44" long (1.12m) HO 1/87, that winds up about 15' (4.55m)

Hey DON !

 Remember , Inertia relates to awfully long stopping distances . Can you say 25 miles ? LOL.LOL. Now the nice part about any of the L.C.C.s and up , all can be built waterline ( i/e loaded ) and there fore a lot of the build is not difficult .

 True, scale size can be a factor so let's not do H.O. scale ( I did two for a shop in California ) Can you say Pick-up Truck delivery ? I would recommend nothing larger than 1/600.  T.B  P.S. that goes for Lakers too !

I'm speculating that the trade-off of reducing drag on the hulls of tankers versus the need to maximize cargo capacity favors the cargo capacity. 

On faster ships like containerships, the hulls are pretty streamlined.

I doubt Coriolis effect would amount to anything noticable for something going less than 20 knots, no matter how big it is.

What is neat about super ships, like many large cargo ships these days, is that because of their size and mass, the dynamics of the vehicle underway is dominated more by inertia than by hydrodynamics, so the hull lines can be very simple compared to older ships.

I have heard that on a fully loaded ship like that, that once underway, they even have to hold some rudder (depending on which hemisphere they are in) to counteract Coreolis effect.  They are basically a rectangular prism with a simple rounding of the bow, flat stern.  Modern bulk carriers on Great Lakes have same hull shapes- easy to model.

 

Then ere a are the LCC, the large crude carriers, which are roughly divisible into two groups; true LCC, and "Panamax." The latter term referring to all ships designed to fit into the maximum dimensions permissible by the Panama Canal locks (circa 880' x 105' x 40' of draft). The next "size" of tankers are the "coastal" tankers, which are often no more than 3-400' long. There's another group of tankers, the river and caanal tankers, which are a very specialized subset of tankers VLCC and ULCC are so large that they often need coastal tankers to offload, as not many of the offshore unloading stations can accomodate them (or in the quantity needing to offload).

A VLCC is a class of oil tankers. The acronym is for "very large crude carrier". I think the class is for ships over 200,000 tons. Then there is the ULCC, over 320,000 DWT. Like a floating island.

Pardon my ignorance, but what is a VLCC model ? I assume it must be made of plastic.

One advantage to VLCC models as an introduction to scratch building is the simple lines.  Most of them have negligible deck camber, and no sheer to the profile.  I would suggest carving solid hull, just a simple curve at the bow, and a bevel of bottom at stern, with a slight rounding of the bottom edges.  Even at 1:700, model would be reasonable size.  At 1:196, a popular ship scratchbuilding scale, it would be really big.  Even that much wood would not represent a lot of cost.  Laminate the hull from board stock (bread and butter method).

Some day I'll get around to upgrading my Texaco North Dakota.

Okay !

    Now , why the naysaying ? If some of you can go all out on a warship , why not give peace a chance ? I did the bow bulb with a 1/72 scale F-104 - Wingtank . Any takers ? C'mon guys why the reluctance ? I know we have some really awesome ship builders here .  T.B.    P.S. If you all prefer , it can be waterlined .

It's an interesting idea. Except I know I can use AutoCAD to map the basic hull solid in about 15 minutes (after enough research to get some particulars for dimensions). I'd probably need another hour fussing with the bow, redoing it about 6 times. From that model it would be no great difficulty to knock out body sections Transfer those to 0.020 stock and a skeleton would be easy enough to cobble up. The top hamper, the piping, the like would take me gadzillions of years to sort out. Now, if I had the unused hull of a super carrier--say, from having waterlined said ship, I'd be inclined towards cobbling up one of the "fast" stores ships, an AOE or AOR--but, that's me; others differ. Or, if I truly had too many bits of hull teasing me, I might bash them together to build up one of those inelegant Panamax ships.--container stacks being able to cover many other flaws.

Hi " G "

 The whole idea here was to help folks think about it with remains of " super-carriers " I don't think the Hornet would cut it , unless you wanted to do a post war Jumboized T-2

 

 T.B.

I don't see the connection. What does an aircraft carrier hull have in common with a VLCC?

I kind of felt that way about my Trumpeter 1/350 Hornet, but it's not at all similar, just kind of slab sided. But no big bulb nose or anything like that.

If I were to model a VLCC, which I don't have plans to do, I would go 1/700 waterline, buy a nice clear piece of 1 x 6 poplar about 24" long. Lay out the hull on it, band saw the shape and spend a few minutes sanding a little flare at the bows and a little counter under the stern. Then done.

Gee !

 It's a surprise ! You mean no one out there has a Glue Bomb or carrier hull with a lot of parts missing ? Oh well , What a waste of good plastic .  T.B.
