Container Ship Accident

Economies of scale have dictated an upward trend in sizes of container ships in order to reduce costs. One limit on ship size is the "Suezmax" standard, or the largest theoretical ship capable of passing through the Suez Canal, which measures 14,000 TEU. Such a vessel would displace 137,000 metric tons deadweight (DWT), be 400 meters long, more than 50 meters wide, have a draft of nearly 15 metres, and use more than 85 MW (113,987 hp) to achieve 25.5 knots, specifications met by the Emma Mærsk.
Beyond Suezmax lies the "Malaccamax" (for Straits of Malacca) ship of 18,000 TEU, displacing 300,000 DWT, 470 meters long, 60 meters wide, 16 meters of draft, and using more than 100 MW (134,102 hp) for 25.5 knots. This is most likely the limit before a major restructuring of world container trade routes. The biggest constraint of this design, the absence of a capable single engine, has been overcome by the MAN B&W K108ME-C.
The ultimate problem was the absence of a manufacturer capable of producing the propeller needed for transmitting this power, which would be about 10 metres in diameter, and weigh 130 tonnes. One has since been built for the Emma Mærsk by Mecklenburger Metallguss GmbH in Waren, Germany. Other constraints, such as time in port and flexibility of service routes are similar to the constraints that eventually limited the growth in size of supertankers.
