Afterwards the vessel was largely employed on the Atlantic Coast of the United States to France route until mid-1921 when she was laid up and eventually broken up for scrap in 1936.

After embarking a cargo of 82,266 barrels of wheat flour, West Compo left Portland on February 9 also carrying on board federal inspectors.

[2] Following decommissioning from the Navy service, USSB allocated West Compo to Strachan Shipping Company to operate on their Southeast United States to France and Low Countries routes.

[16] On her last return trip from Stettin and Brest she became disabled soon after leaving the French port on 11 April 1921 and had to be put back with a help of the USSB tug for quick repairs.

West Compo arrived at Savannah on May 4 where she was returned by Strachan Shipping to the USSB due to overabundance of tonnage and scarcity of cargo.

[17] The freighter was first towed to Charleston in early December 1922 where she remained for the next eight month before finally arriving in Newport News on 15 August 1923 to become part of the USSB reserve fleet.

[20][21] In early September 1932 the Shipping Board decided to scrap 124 World War I era vessels in its possession, including West Compo, to alleviate significant tonnage overabundance.

[22] In October 1932 it was announced the whole lot of these vessels was sold to the Boston Iron and Metal Company of Baltimore for $1.51/ton of recoverable of material which was believed at the time to be over 350,000 tons.
