Maersk Triple-E Ship at night

Forty-thousand alarm clocks buzzed as one, waking an equal number of workers for work at Daewoo Shipbuilding & Marine Engineering (DSME), the world’s second-largest shipyard, just before dawn on Geoje Island, along South Korea’s southwest coast. As the sun rose, they marched out for another day’s labor at the company’s immense dry docks, dominated by the soaring arc of a Brobdingnagian hull. Giant barge mounted cranes float past the docks, where they had laid each mega-block section, enormous, pre-fabricated ship segments onto a blacktop larger than a Walmart parking lot.

The enormous ship, due for launch on June 28, is the world’s biggest. A behemoth even in a world of behemoths, and the first sibling in a new fleet of 19 sisterships. The vessel will have the ability to carry 18,000 twenty foot shipping containers and will weigh-in at 165,000 metric tons, the equivalent mass of all the gold ever mined.

Sheer size is her most distinguishing feature. At 400 meters, the M/V Maersk Mc-Kinney Møller, as she’ll be called, is significantly longer than any aircraft carrier or even the Titanic, and only slightly shorter than the Empire State Building is high. Standing on her bridge is like peering over the rim of the Grand Canyon. From her highest deck, shipyard workers resemble overgrown ants and officers needing to walk the bridge’s width, wing-to-wing, will wish they had packed roller skates.

Why so large?

The M/V Maersk Mc-Kinney Møller, first vessel of the A.P. Moller-Maersk Group’s new Triple-E class container ships, leverages unprecedented economies of scale and energy efficiency, as well as a new generation of environmental safeguards. Its sheer size helps maximize each of these factors while reducing the cost and environmental impact of shipping each container.

Costing just under $200 million to build, the ship is powered by two engines, each one diminutive compared to the single 109,000-horsepower diesel of the Emma Maersk, the largest container ship in the world when it was launched in 2006. And the new ship’s cost, high as it seems, is only one-fifth the price of the Floating Production Storage Offloading (FPSO) vessels the offshore oil and gas industry uses to store and process oil, or less than 7% the cost of one Prelude Class FLNG.

Colossal Scale, Pinpoint Precision

Despite its size, the M/V Maersk Mc-Kinney Møller was built with pinpoint precision. “Construction of the ship was a massive international effort,” said Peter Bertelsen, Lead Hull Superintendant for Maersk. “But it’s not rocket science, just a big puzzle, a 3-D puzzle.” Each of the ship’s 31 pre-fabricated mega-sections were lifted by a giant scissor lift crane then dropped into the dry dock and neatly aligned to within four millimeters of the adjacent block.

About 250 people work on each ship during the final stages of construction, according to Bertelsen and Y.S. Lee, his DSME counterpart, with few tasks automated. “The steel is cut by giant, computer-operated lasers, but the rest is done by human hands,” said Lee. “Each section is moved into place using hand signals and radios and the sections are welded together by dozens of individual welders.”

Acquiring the colossal sections, however, required the efforts of thousands of laborers who ordered, built and moved the millions of individual parts within each monster slice. DSME’s facility in Shandong, China- one of three shipyards building the M/V Maersk’s megablocks- constructed 40 percent of the sections, which heavy lift ships then transported to Goeje Island.

At Goeje, operators of the yard’s giant cranes and transporters secure each section into place.

The M/V Maersk Mc-Kinney Møller, despite its record-busting bulk, is fitted with standard equipment. The lifeboats (made in China) are small and the bridge systems, while modern, are less impressive than those found aboard the latest Offshore Supply Vessels.  The captain will occupy a comfortable suite adjoining the bridge that consists of a cabin, a day room and an office. But each room — cozy, not spacious — is no larger than a single crew cabin.

The vessel’s top speed is 23 knots, a bit slower than the design speed of older, smaller container ships which did not contend with the issue of an over-built containership industry, or extremely expensive fuel.

Invisible Achievements

The M/V Maersk’s principal achievements lie in benefits invisible to all but accountants, naval architects and environmental experts, but the cumulative results are outstanding. Triple-E vessels will travel 184 kilometres using 1 kWh of energy per ton of cargo, whereas a jumbo jet travels half a kilometre using the same amount of energy per ton.

The savings are the result of a unique hull design, an energy-efficient engine, a waste heat recovery system, which uses exhaust gas to produce extra energy to help propel the ship, and a vast economy of scale. Combined, these factors denote that the Triple-E will emit 20 percent less CO2 (per container moved) compared to the Emma Maersk and 50% less than the industry average on the Asia-Europe trade lane.

World Record Size

With a sailing draft of 14.5 meters (48′) she is too deep for most American ports and according to Maersk, the vessel will be calling on just 13 ports, all located in Asia and Northern Europe. The vessel is also too large for even the expanded Panama Canal, but is well within the maximum 20 meter draft and 77.5 meter beam requirements for vessels sailing through the Suez Canal.

The ship is certainly impressive but is not the largest ship ever built, that honor goes to the Knock Nevis, a 458 meter ULCC supertanker scrapped in 2010. She is expected to be listed in the next year’s Guinness Book of World Records, though she will not hold the world’s biggest ship distinction for long. At 400 meters she is 88 meters shorter in length than the Shell Prelude FLNG already under construction across the island at Samsung Heavy Industries, and she displaces close to half the water of the impressive dual-hulled heavy-lift pipelay vesseel, sip Pieter Schelte which was recently launched at DSME.

Regardless of competition, new and old, the M/V Mærsk McKinney-Møller is a thoroughly impressive vessel that will dwarf most other ships including America’s largest aircraft carriers.

    Great article guys! In depth, well written.. Why don’t you guys write more like this one?

  • Total

    An aircraft carrier can only go 33 knots, so the Maersk’s top speed is about 2/3rds of that, not half.

    • Bob

      That jumped out at me, too, though it’d be fun/insanely scary if a CVN could make 46 kts…

      • Brendan

        actually a CVN can make speed of over 35 knts. The speed is actually classified.

    The article on Waste Heat Recovery that accompanies this article is very poor. There was no place to comment for the article, which comes from a different website, but it seemed clear that the article was written by someone who had press releases but little experience on ships. I spent my working life on Containerships and they all had waste heat recovery as described in the article, yet the article maintained that no ships had used it before, or that it was new. The article talked about Steam being generated by waste heat (very old school) and then being used to power a gas fired boiler. Really? If it was gas fired, and making steam that way, how did they use steam to fire it, or how would you. This area is very important to the future of the industry, and could have been quite informative, but sadly was not at all well written. Also, on these articles about new ships, please include more details about the actual equipment installed, not generalities such as wow this engine sure is big.

  • Pekka Joki

    Mr. Bruce Sherman’s comments are right. There are so many important things to mention than the size of the vessel.

  • Ronald A Palmer

    A very well written and informative article. It may be that the growing size of these ships will be eventually curtailed by the limited number of ports with sufficient depth of water. A pleasing factor that is noted is the Masters accommodation being on the bridge deck with a nice suit of rooms. Obviously the Chief Engineer is well below the top deck where the pig iron polishers should be kept. Many of the relatively modern ships have the Chief Engineer sharing the same deck as the Master. This brings an unsatisfactory aroma of lube oil, grease etc. Keep those pig iron polishers well below decks where they belong.

      Ronald A Palmer, The memories of being manhandled by those pig iron polishers must be haunting still…..i suggest seeing a therapist and keep yourself away from this Profession.

  • wtb33

    Ronald A. Palmer,
    If you knew half the hardships that marine engineers go through, you wouldn’t have said that. Do some research and maybe even spend some time down in the engine room. Then and only then are you qualified to post a comment on here.

  • hassan

    this ship will also drop in to the water like titanic i promise if it dont drop so i will drop it in to the water i promise if you can stop me so stop hahahaha
