OCEMA is an association of major U.S. and foreign flag international ocean common carriers. OCEMA provides a forum for its members to discuss, evaluate and reach agreement with respect to matters pertaining to the interchange, transportation, use and operation of carrier equipment in the U.S. Included in its scope are equipment-related operational, safety, and regulatory activities such as participation in industry forums, educational sessions, regulatory proceedings and legislative matters.

OCEMA members operate worldwide and serve all major U.S. ports and inland locations, moving cargoes primarily in containers. As a regular part of intermodal transportation services provided to U.S. manufacturers, importers, retailers and others, OCEMA members interchange cargo to be carried to and from U.S. inland locations via motor carriers and railroads. An essential element of these inland operations involves the movement of containers on intermodal chassis and rail cars.

OCEMA's activities are authorized under the U.S. Shipping Act, as amended. The OCEMA Basic Agreement is filed with the Federal Maritime Commission.


  • OCEMA members have included both U.S. and foreign flagged carriers.
  • All 10 OCEMA members are ranked among the top 40 of Alphaliner's top 50 U.S. Global Container Fleet operators.
  • OCEMA members control 80% of the total market share as reported by Alphaliner's top 50 U.S. Global Container Fleet operators.


The intermodal system depends upon a relatively simple piece of equipment to move a container between an intermodal terminal (rail or ocean) and an origin or destination.
