Marine Safety Detachment Sturgeon Bay

Marine Safety Detachment (MSD) Sturgeon Bay is a multi-mission unit responsible for executing the Coast Guard's Port Safety and Security, Marine Environmental Protection, and Commercial Vessel Safety missions under the Department of Homeland Security.

MSD Sturgeon Bay's devoted group of professional active duty personnel protect the busiest and most dynamic port in Wisconsin. They perform a variety of tasks each day, ranging from conducting port security patrols, processing vessel arrivals, inspecting U.S. and foreign commercial vessels, and conducting waterfront facility exams for compliance with federal regulations.

The MSD's area of responsibility includes 21 facilities that are subject to the Maritime Transportation and Security Act (MTSA) of 2002, including several oil transfer facilities. In an average year, the MSD AOR receives 150 foreign vessel arrivals, of which 80 come from ports in Europe and South America with the remainder coming from Canadian ports. Our AOR for maritime inspection extends 35 nautical miles offshore and includes all navigable waters of western Lake Michigan from Kenosha, WI to Thompson, MI (just west of Manistique, MI), covering over 300 miles of coastline.
