Bringing cargo-loading operations to completion on 13 May, Renate embarked 197 enlisted passengers — sailors, marines, and soldiers — and two naval officers for transportation the following day, and sailed for the Marshall Islands.

Steaming independently, her men standing daily dawn and dusk alerts, the attack cargo ship crossed the 180th meridian on 18 May, and ultimately reached Eniwetok on the 22nd.

The boats would be used in charting positions and depths accurately, while the ship's helicopter would transport surveyors and their equipment to points ashore and perform aerial photographic missions.

During 1949, 1950, and 1951, Maury made three 8-month cruises to the Persian Gulf, constructing charts of those waters, accompanied by the tugs Allegheny and Stallion.

Through 1957 she served in the Western Atlantic, surveying as far north as Newfoundland in the summer months and working to the south, as far as the West Indies, during the winter.

In July her North Atlantic resurvey missions were extended and she crossed the ocean to chart the waters in and around the Shetland and Faroe Islands.

Throughout this period, while fulfilling her primary assignment of correcting navigational charts, she added to meteorological knowledge by studying the North Atlantic's weather patterns, particularly with regard to hurricanes.

Working in concert, Maury concentrated on hydrographic survey, while Serrano gathered information on the physical and chemical makeup of the waters and ocean floor.

Into 1969 her efforts added significantly to knowledge of the characteristics of the coastal area in which U.S. naval forces conducted riverine warfare and amphibious operations.

She reached San Francisco on 8 December 1969, off-loading fuel, ammunition, and vehicles before shifting to the Naval Inactive Ship Maintenance Facility, Mare Island, Vallejo, California (USA), later the same day.

Taken to MARAD's Suisun Bay, California, berthing area, she remained there until sold to the National Steel and Metal Co., of Terminal Island, Calif., on 10 August 1973 to be broken up for scrap.
