[1] Following outfitting there and shakedown training in nearby waters and off the Virginia capes, the coastal minesweeper arrived at Portland, Maine on 26 September and reported to the commanding officer of Mine Division 26 for duty in the inshore patrol.

For almost one year — but for a month of availability at the Boston Navy Yard from 18 March to 17 April 1942 — she performed her duties of streaming and sweeping for mines.

[1] In mid-August 1942, orders arrived directing Accentor to proceed via Boston to Annapolis, Maryland for minesweeping tests in the Chesapeake Bay.

[1] After World War II ended and most postwar minesweeping tasks had been completed, Accentor was placed out of service on 14 June 1946 and, a week later, declared surplus to the Navy needs.

Struck from the Navy list on 3 July 1946, she was transferred early in October 1946 to the Maritime Commission for disposal and sold to Higgins, Inc., of New Orleans, Louisiana.
