1947:

The Coast Guard announced the disestablishment of all US Coast Guard Merchant Marine Details in foreign ports.  During World War II, a total of 36 foreign Merchant Marine Details had been activated for the purpose of performing "on-the-spot" services in connection with the preventive aspects of safety of life and property of the US Merchant Marine.  These functions reverted to continental US ports in which there were located US Marine Inspection Offices.
