One wonders how many in a row this world's largest shipping company (as well) based in Denmark has had this record of having the world's largest ship - I wonder also if not a newer A.P. Møller Maersk ship has overtaken this record nowadays already from EMMA MAERSK (I might be very wrong...)
The famous shipowner at a very high age died last year, also famous as a sponsor of the great new Opera house of Copenhagen.
A very pitoresque detail on this company's all ships are, when they are registred under Danish flag, many of these incredible giants are registred with very different homeports painted in their stern, wonderfully named with sometimes the smallest fishing boat villages under the ship's names, which these ships not by far could reach even at distance... but a very fine gesture of this company and just not simply register all their ships in 'København'(Copenhagen).
The Emma Maersk was the largest container ship when she was completed in 2006. She is 397m long; 170,794 Gross Tons and 156,907 Tons Deadweight.
The Maersk Mc-Kinney Moller became the largest container ship in 2013. She is 400m long; 194,849 GT and 194,153 DWT
The tanker Seawise Giant was delivered in 1979 and scrapped in 2010. She was 458m long; 260,941 GT and 564,763 DWT
The ore carrier Vale Brazil was delivered in 2011. She is 362m long; 198,980 GT and 402,357 DWT
The cruise ship Allure of the Seas was deliverd in 2010. She is 362m long; 225,282 GT and 19,750 DWT
I have changed the photo title and moved it to the Container Ship Gallery
With gross tonnage being a volumetric measure of a ship's enclosed space and therefore a true indicator of a ships size, Maersk McKinney Moller is actually only the third biggest in terms of actual size of the ones mentioned above. There's an awful lot of old marketing (and ignorant) bull**** bandied around about ship sizes, particularly about a ship "weighing" its gross tonnage. BTW: Emma Maersk has a deadweight (ie carrying capacity) of 156,907 TONNES (of 1,000 kilogrammes WEIGHT)
Net tonnage is also a volumetric measure but only of the cargo-carrying areas. Deadweight all-told (DWAT) is the WEIGHT of stores, fuel and cargo that will put the vessel down to its marks. Cargo deadweight is the DWAT minus stores, fuel, etc, leaving you with the weight of cargo that can be carried with the vessel down to her marks. Deadweight is nowadays measured in metric tonnes ( 1 tonne = 1,000 kilogrammes). Net and gross tonnage are calculated by measuring a ship's internal volume and applying mathematical formulae.
The only objective ship measure is the displacement - the ship's weight. The light ship displacement is the ship without cargo, crew, fuel. The full displacement is the ship at maximum draught with fully loaded and full fuelled. The difference between Light ship and maximum Displacement is the deadweight. (D/zero/ + Deadweight = Maximum displacement). Since 1975 these weights are Always to be told in metric tonnes according to an international agreement. Also all Lloyd's Register books are since 1975/76 mentioned in metric tonnes on the deadweight measures. Displacement is not disclosed (as it is a technical know-how and holy secret to disguise to most shipbuilders) in most registers, except for some few Register Societies, like Russian RS which openly present the displacement officially.
Gross and Net tonnage are confusing figures - the older measures GRT and NRT (London Convention of 1947) was measured as 1 register tonne is 100 Cubic feet or 2,83 cubic metres. The NRT is used for tax and port fees what sum to be paid for the ship. The new measurement in GT and NT (Oslo Convention of 1969, fully in charge from 1994/95 on all merchant ships) has, strangely, no measure and is measured under most complicated cir***stances - and to my mind this is nowadays not a very good objective comparasion measure at all.
So if one knows the ships full loaded displacement - this is the most true and best measure to compare ships. All naval ships are measured in displacement (weight) tonnes - but the merchant ships with the confusing GT and NT - just compare with the new OASIS class built in Finland for RCCL - ships which has larger NT than the total GT-Gross Tonnage!! What a mess!
