[edit] North Atlantic route

How long does it take for a container ship to go form the USA (take New York) accros the Atlantic to Europe (for example to London) ? --Laurenttas 13 November 2004

New York-Newark to Southampton or Felixstowe/UK route was 6 days to cross the atlantic. --217.9.49.2 21 June 2005

[edit] helding the stack

Does anyone know how the stacked containers are held to the ship above the deckline? I know there are little twist-lock things for stacking on railroad cars, but it can't be the same mechanism, it'd be much too tedious. --Benandorsqueaks 18:13, 8 January 2006 (UTC)

Above deck containers are secured with twistlocks at each of the four corners. For vessels, these are now required to be either of the semi-automatic variety or are the newer fully-automatic twistlocks. The semi-automatic twistlocks ratchet to release when a short wire is pulled by a longshoreman with a pole from the deck. The newer fully-automatic twistlocks are designed to ratchet automatically when the gantry crane lifts the container. Additionally the lower few tiers of containers are normally lashed to the deck with rods and turnbuckles for additional securing during transit. --68.208.147.168 16 February 2006

[edit] Hatch

What are the different types of hatchcovers being used in containerships in breakbulks there is a bontoon hatch --61.17.27.53 15 July 2006

"bontoon hatch" is wrong terminology. The hatch is the opening into the ship's hold which is created by the removal of the hatch cover. On breakbulk ships this cover is made of steel and it has a hollow core. This type of hatch cover is called a "pontoon". Container ships have a much heavier and more substantially built hatch cover. The hatch cover of a container ship may weigh 40 long tons.--69.143.150.67 04:06, 27 July 2006 (UTC)

[edit] decimal / thousands

Someone is using the . for both a decimal point and a thousands separator. I will fix it now.—Preceding unsigned comment added by 71.102.186.234 (talk • contribs) 27 September 2006

[edit] Container_ship#Largest_ships

This table has many defects:

• no references
• too long
• many sisterships could be summed in one class
• inline presentation

I should at least move it to a separate article, if not removing it for being an eternal source of inaccuracies. --Marc Lacoste 22:09, 10 October 2006 (UTC)

I would second this comment. In addition, what is/are the 'GT' tabulated in the column bearing this title (I think I know, but this abbreviation occurs nowhere else in the text)? What is their relevance? Similarly, the expression 'DWT' is used in the text but not defined. Shouldn't there be a link to Wikipedia article on Tonnage here? --Paulredfern1 12:13, 18 December 2006 (UTC)

I propose to replace the table by the table of the German Wikipedia, but also in the table of German Wikipedia the column BRZ should be removed. The reason is, that the interesting number for a container ship is the TDW. This number defines how many filled container with normal weight can be loaded.

Example: The Eamma Maersk carries 11000 container with 14t each. The sum is 154000t. The TDW is 157000. There 3000t for fuel and so on.

The values GT and BRZ are volume values. They are not important and very often there is a confusion also in the source documents - and than the values are wrong --Roland Schmid 22:01, 20 December 2006 (UTC)

For most I agree with you Roland. From commercial (charterers) aspect the amount of homogeneously loaded 14tons (8'6" high 20ft long) containers that the vessel can carry is the most important value/particular. For this count the vertical centre of gravity is normally taken at 45% of the containers height as well. Since this value is a selling argument it is often given in the descriptions of the vessel. I feel these values should be mentioned in any table about container vessels. For the same reason I do not agree with the notes that are listed underneath the table. So it is probably best to delete the table anyway and only mentione the largest container vessel sailing today.beapeet 10:28, 25 December 2006 (UTC)

The list was made with the information provided here. http://www.containership-info.net.tc --Pcpirate16 April 28 2007

[edit] mpg

what is the mpg [or km/litre].. or, gallons per mile even, of these things (typical, obviously)

[edit] Contradiction?

This page: "The first container ship was the Ideal-X, a converted T-2 tanker, owned by Malcom McLean, which carried 58 metal containers between Newark, New Jersey and Houston, Texas on its first voyage, in April 1956."

Another Wikipedia page - http://en.wikipedia.org/wiki/Containerization: "The first vessels purpose-built to carry containers began operation in Denmark in 1951. Ships began carrying containers between Seattle and Alaska in 1951."

[edit] Costs

Does anyone have any information about indusrty building/shipping costs and the cost effectiveness of container ship versus other kinds of shipping? 140.180.166.176 00:01, 27 March 2007 (UTC)
