Welding Shipyards was founded by American shipping businessman, Daniel K. Ludwig (1897–1992) in 1940 at Norfolk, Virginia on the Sewell's Point peninsula. Welding Shipyards build T3 tanker ships for World War II under the Emergency Shipbuilding Program. Welding Shipyards had one construction berth with 600 workers. The shipyard built what Ludwig was known for Oil tankers. Welding Shipyards built five type T3-S-BF1 tankers, the largest at the time.^[1] Ludwig' Welding Shipyards used what is called block construction. To shorten keel to ship launching time due losses to German U-boats, block construction was used. Ships blocks were built as the keel was being laid and then the prefabricated parts were then put in place and welded. With this construction time was reduced dramatically. Welding Shipyards and Ludwig had an important role in this new type of construction.^[2]^[3] All of the tanker ships were operated by Ludwig's shipping company that he founded, the National Bulk Carriers in 1936 in New York. National Bulk Carriers owned and operated oil tanker ships and bulk carriers. Some of the ships were among the largest in the world at that time. In 1953 Ludwig moved the shipyard operated to the Kure shipyard in Japan. Ludwig leased the Japanese navy Kure yard for 10 years (1950 to 1960). The Welding Shipyards site today is part of the Naval Station Norfolk.^[4]^[5] In 1940 and early 1941, Welding Shipyards converted older World War I surplus cargo ships into oil tankers.

Notable incident

USS Pan Pennsylvania, a Type T3-S-BF1 tanker, on 16 April 1944 was sunk off Nantucket by a torpedo from U-boat U-550 commanded by Klaus Hänert. Pan-Pennsylvania was steaming from New York Harbor on the afternoon of 15 April 1944 as part of convoy CU-21, going to England with 140,000 barrels (22,000 m³) of 80-octane aviation fuel.
