Towed by, Barite departed San Francisco on 25 September 1944 and entered Pearl Harbor on the morning of 2 October. Clearing that port four days later, again astern of Iroquois, the barge proceeded to Eniwetok. Thence, under tow by the auxiliary ocean tug ATA-124, with as "retriever" and YMS-276 as escort, Barite reached Ulithi, in the Caroline Islands, on 13 January 1945 and joined the armada of 225 ships present at that advanced base.
Barite served at Ulithi as a floating lubricating oil facility into the spring of 1945, when the advent of the typhoon season made it imperative to shift Service Squadron (ServRon) 10's base to locales other than the Western Caroline Islands. Towed thence to Saipan on 15 May, she operated at that island, in the same capacity, as a unit of Service Division 101, a part of ServRon 10. Towed from Saipan on 30 June 1945, Barite was moved to Leyte, where she served through V-J Day.
Reassigned from Service Division 101 directly to the parent command, ServRon 10, on 28 August 1945, Barite remained in Philippine waters for the remainder of her naval service.
Barite was taken out of service and delivered to the War Shipping Administration at Subic Bay on 5 August 1946, and her name was struck from the Naval Vessel Register on 15 August 1946. Subsequently sold to the China-based Asia Development Corporation, the ship was delivered to her purchaser on 23 April 1948. Lloyd's Register of Shipping carried the former Barite through the 1950-1951 editions, after which time she disappeared from the scene.
