Final answer:
The movement priority of personnel and cargo in the global shipping network is influenced by market demands and environmental regulations, with bulk carriers and container ships having distinctive operational behaviors.
Step-by-step explanation:
The movement priority of personnel and cargo is subject to various factors within the global trade network. Cargo ships operate within a complex network of routes that are driven by market demands and environmental conditions. For instance, bulk carriers typically travel between two ports, either fully loaded with cargo or in ballast, and their destination changes according to the market dynamics.
Container ships, however, have more regular routes with frequent stops to load and unload. They also utilize internal ballast water (BW) transfers to maintain stability without the need for discharging, following management regulations that aim to prevent the spread of invasive species.
Additionally, container ships have adapted by sourcing BW from the open ocean instead of coastal waters, reducing the requirement to conduct ballast water exchange (BWE). These movements are part of the global shipping network, which is a crucial component in the globalization of the economy, facilitating trade across the world.
