Container Ship Accident

Cargo too large to carry in containers can be handled using flat racks, open top containers and platforms. There are also container ships called roll-on/roll-off (RORO), which utilize shore-based ramp systems for loading and unloading. ROROs are usually associated with shorter trade routes, as they are unable to carry the volume of crane-based container vessels. However, due to their flexibility and high speed, ROROs are frequently used in today's container markets.
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.
