Their operation can be more cost-effective in well-equipped ports where loading and unloading infrastructure is readily available.
3. Coastal Trade Liners
Designed primarily for shorter sea journeys, coastal trade liners operate along coastlines and between neighboring countries. These vessels are typically smaller, allowing them to navigate through shallower waters and access smaller ports that are inaccessible to larger ships. They play a crucial role in domestic and regional trade, transporting goods efficiently along coastal routes.
4. Sea-River Vessels
Uniquely designed to navigate both in the open sea and on inland waterways, sea-river vessels are versatile ships that can reach ports located far inland. Their design takes into account the limitations of river depths and bridge heights, making them invaluable for transporting goods to areas that would otherwise require additional land transportation.
Larger MPVs are capable of carrying a diverse range of cargoes on a single voyage, offering a significant advantage in terms of flexibility and cargo consolidation. This capability allows shippers to maximize efficiency and reduce costs by combining different types of cargo for the same destination. In contrast, smaller MPVs, although they may not offer the same level of cargo versatility, are indispensable for reaching smaller harbors with limited draught access. Their ability to operate in such conditions ensures that goods can be delivered closer to their final destination, enhancing the overall efficiency of the supply chain.
