In 1947 Ponaganset fractured into two sections while tied up at dockside in Boston:
The source of the fracture was an arc strike located at the toe of a fillet weld that joined a chock in the deck. The presence of the sharp cracks in the arc strike located in a region of high residual stress resulting from the fillet weld provided the necessary conditions for fracture initiation at tem-peratures below the NDT. As indicated by the fracture analysis diagram, the failure temperature was 15°F below the NDT temperature of the source plate. The steel was typical of the World War II production material which features relatively high carbon and low manganese contents.
( U.S. Naval Research Laboratory report 5920 )
On 2 March 1948 the vessel was reacquired by the Navy "as is where is". On 2 June 1948 title was transferred back to the Maritime Commission at the Boston Naval Shipyard on 30 June 1948. She was sold for scrap to Northern Metal Company on 7 January 1949.
