Definition & Explanation
Deep-sea shipping is the ocean transport of goods and passengers across major maritime distances, primarily on intercontinental trade routes linking large commercial ports. It relies on purpose-built vessels – container ships, bulk carriers, tankers, and ro-ro ships – operating on lanes such as Asia–Europe or the transatlantic corridor. Deep-sea operations fall under international maritime law and the frameworks of the International Maritime Organization (IMO), including SOLAS for vessel safety and MARPOL for pollution prevention. Unlike short-sea shipping, which covers regional coastal routes, deep-sea shipping is the backbone of high-volume cargo movement in global trade: freight cost per tonne is low, but transit times range from weeks to over a month depending on the route.
