Feeder Operator
A Feeder Operator runs short-sea shipping services that connect smaller regional ports to the major hub ports where deep-sea container vessels call. The economic logic: a 24,000-TEU mega-vessel cannot economically call at small ports, so cargo is consolidated at major hubs (Singapore, Rotterdam, Jebel Ali) and "fed" by smaller feeder vessels to/from regional ports.
Feeder operators may own their own vessels or charter them; they hold "slot" agreements with deep-sea principals for the feeder leg. Operationally, feeder lines manage slot allocations from deep-sea principals, intra-regional sailing schedules, container booking, manifesting, port-to-port coordination, EDI reconciliation, and revenue accounting per slot.
A 24,000-TEU mega-vessel cannot economically call at small ports, so feeders shuttle boxes between regional ports and the big hubs. This hub-and-spoke model is what lets the largest ships stay full and fast while still reaching smaller markets — the feeder leg is the spoke.

Why are feeder services needed?
Because the largest container ships only call at a handful of deep-water hub ports. Feeders connect the many smaller regional ports to those hubs so cargo can reach the mainline network.
What is a hub port?
A major transhipment port (such as Singapore, Rotterdam or Jebel Ali) where deep-sea vessels call and cargo is consolidated and redistributed by feeders to regional ports.
