In January 2018 Elm went into drydock at the Coast Guard Yard in Baltimore for a mid-life major overhaul. She left the yard on June 13, 2019. On July 15, 2019 Elm reached her new homeport, Astoria, Oregon, replacing Fir, which sailed for Baltimore for her own mid-life overhaul in June 2018. Fir's crew, already familiar with the operating area, took over Elm.
