There, the cargo ship received a load of lumber from the Weyerhauser Co. before sailing west to Hawaii, arriving in Pearl Harbor on 1 March.

After unloading her cargo—Manus was a support base for the ongoing operations in the Philippines and the Ryukyus -- Beltrami sailed to Ulithi, Caroline Islands, on the 25th, anchoring there four days later.

[3] Beltrami sailed to the Philippines late in August and spent nine weeks operating in the Leyte area, providing passenger and cargo service to the forces ashore.

[3] While at that base, the ship received orders to prepare for Operation Nanook—a project to set up a system of weather stations in the Arctic regions of the Western Hemisphere.

She first made brief stops at Baltimore, Maryland, and Philadelphia, Pennsylvania, in mid-April, both to obtain cold weather gear and to receive equipment modifications for extended sub-zero operations.

Beltrami then sailed to New York, embarking LCVPs and picket boats in early May, before moving on to Boston, Massachusetts, to load a detachment of US Marines.

[3] On 25 July, after passing through the Labrador Sea and the Davis Strait, Beltrami rendezvoused with the icebreaker Northwind in Lancaster Sound, well above the Arctic Circle.

Her crew unloaded the cargo and heavy equipment needed to construct a weather station and an emergency airstrip, before the ship returned to Dundas Harbor on 20 August and reembarked the marines after their three-week field expedition.

Made obsolete by larger and faster cargo ships, Beltrami sailed from Norfolk to Charleston, South Carolina, in late July 1955, arriving at the navy yard there on the 29th.
