- Conventional. A single sequence that covers the entire East Coast through main ports of call. The drawback of this configuration is a longer service time.
- Direct. The East Coast can be serviced by three (or more) different direct services, each focusing on a specific sub range such as the North Atlantic, Central Atlantic or South Atlantic / Gulf Coast. This regional service specialization is slightly more time effective than the conventional service and also has the advantage to offer a wider level of port coverage. These services can also be arranged in terms of containership capacity, with for instance 8,000 TEU ships calling East Coast ports having the capacity to handle them.
- Transshipment. Similar to the previous configuration, but with the insertion of a transshipment hub (or more), most likely within the "Caribbean transshipment triangle" where deviation from major shipping lanes is reduced. The regional services become feeder loops with smaller ships but higher frequencies.
- Circum-equatorial. Involves an additional hierarchy in the network structure with a global maritime shipping system with a circum-equatorial "conveyor belt" serviced by high capacity containerships (8,000 to 12,000 TEU; new Panamax). In this case the Caribbean transshipment hub acts as an interface between several major systems of circulation, namely the Asia-Caribbean-Mediterranean circum-equatorial route and north-south connectors to South America.
