Marine Inspection Detachment Baton Rouge was established in late 1966. In the early 1980's, the detachment was upgraded to Marine Safety Detachment (MSD) as a detachment of Marine Safety Office New Orleans. The Crew gradually increased from 2 personnel to 32 active, 1 civilian Port Security Specialist, 28 reserve and 52 Auxiliarist from U.S. Coast Guard Auxiliary Flotilla 4-10. The creation of MSD Baton Rouge drastically reduced the response time to the rapidly growing ports of Greater Baton Rouge. MSD Baton Rouge was upgraded to a Marine Safety Unit in February 2001 with its own Commanding Officer and Executive Officer.
This devoted group of professionals protects one of the busiest and most dynamic port areas in the United States. Marine Safety Unit Baton Rouge's primary responsibilities include vessel inspections, foreign and US vessel boardings, facility inspections, pollution response and port security. Our area of responsibility includes the navigable waterways of Mississippi River from the Sunshine Bridge Crossing (Mississippi River mile marker 167) to above the Old River Lock Structure at mile marker 303. This also includes the Atchafalaya River, Morganza Spillway, Intracoastal Waterway and Port Allen Route, Lake Maurepas, Bayou Sorrel, Bayou Pigeon, Red River, Grand River and Bayou Choctaw.
In an average year, MSU Baton Rouge conducts approximately 1000 vessel inspections, conducts approximately 75 foreign vessel examinations, conducts over 175 inspections on 75 bulk liquid and dry bulk facilities, investigates approximately 200 pollution incidents and investigates over 200 marine casualties.
