bottom. On 23 June, after six months with her port side beneath the surface, Oglala was floated. The salvage crew was unable to bring her to the draft depth required by the keel blocks in the dry dock, however, and the ship was unsteady. Work began to increase draft and improve her stability but during the night of 25–26 June 1942, the pumps being used to keep her afloat were overwhelmed by an influx of water and she settled to the bottom again. An investigation revealed that the fuel line for the main gasoline powered pump had become clogged overnight, and the electrical back-up pump was not effective because the water level did not rise high enough. While attempting to refloat her again on 29 June, a failure to the cofferdam in aft section caused her once more to settle down. It was determined that, for a second time, the field crew had not built the cofferdam to the proper specifications. After repairs to that, she was floated for a third time on 1 July. A spillage of gasoline on the same day while refuelling caused a fire that was extinguished in 30 minutes, before it could cause any serious damage. When Oglala was finally towed to the dry dock, the bow was the only part of her above the waterline. Once she was settled into the keel blocks, the refitting work began. Conversion to internal combustion engine repair ship On 23 December 1942, Oglala was sea worthy. She sailed via Mare Island for the shipyard at Terminal Island Naval Dry Docks and was moved into the shipyard itself on 1 March 1943. Reconstruction plans finalized at Mare Island meant that her days as a minelayer came to a close. Her refitting included a complete conversion into an engine repair ship. On 15 June 1943, Oglala was reclassified to an internal combustion engine repair ship ARG-1. While she was undergoing conversion, Oglala remained assigned to Mine Squadron (MinRon) 1 in the Service Squadron (ServRon) within the Pacific Fleet. In November, she received word that her assignment would be shifted to the Seventh Fleet when she completed converting. Due to construction delays, Oglalas conversion missed the initial completion date of 1 February 1944. She had been scheduled to begin dock trials on 17 February, but the lack of progress by the construction crews caused them to be cancelled. On 28 February,
