Container Ship
A Container Ship is a cargo vessel designed to carry standardised shipping containers, stacked both below deck in cell guides and lashed in tiers on deck. Its capacity is measured in TEU (twenty-foot equivalent units), and it is loaded and discharged by shore-based ship-to-shore gantry cranes, enabling very fast turnaround compared with break-bulk.
Container ships range from small feeders (a few hundred TEU) serving minor ports up to Ultra Large Container Ships exceeding 24,000 TEU on the main trades, via Panamax and post-Panamax classes. They run to fixed liner schedules on defined routes, and their standardisation is what makes intermodal transport and modern global trade possible. The relentless growth in container-ship size has driven ports to deepen, invest in bigger cranes and expand yards to keep pace.
The container ship is the machine that made globalisation — standardised boxes, fast crane turnaround and fixed liner schedules that moved manufacturing across oceans. Its size classes and the race to build bigger shape port investment worldwide. It is the single most important vessel type in modern trade.
How is container ship capacity measured?
In TEU — twenty-foot equivalent units — from a few hundred on feeders to over 24,000 on the largest ships.
What are cell guides?
Vertical guides in the holds that slot containers into place for secure, fast stacking below deck.
