The San Fraterno- class was a group of ten oil tankers . They were the largest oil tankers in the world when they went into service right before the outbreak of the First World War .
Five of the ships were in the late 1920s to whaling - factory vessels rebuilt.
history
background
The Royal Navy was in the midst of converting its ships from coal to oil in 1911/12. Weetman Pearson , who later became Lord Cowdray and owner of the British Pearson Group with a strong business interest in Central America, especially in the Mexican region (Aguila (Mexican Eagle) Oil Company), received an order from the Admiralty to set up the necessary production infrastructure and a long-term supply contract large amounts of fuel oil. To this end, Pearson founded a London subsidiary, the Eagle Oil Transport Company, and ordered six ships, each with a 9,000 ton deadweight, the San Dunstano class and ten ships with a 16,000 ton deadweight, the San Fraterno class.
Resumes
The ships had remarkably different lives. Seven ships were torpedoed during the First World War, five of them sunk. Three of the torpedoed ships were brought in or lifted after the war and later converted into whale boilers. The type ship San Fraterno was also among those torpedoed, but it only sank years later, in 1927 at Carlos Island. From 1919 the remaining ships under Shell paints were employed in the crude oil and product trade. Half of the class, the San Gregorio , the San Jeronimo , the San Lorenzo , the San Nazario and the San Patricio were converted into whaling mother ships in the late 1920s . During the Second World War , two of them, the Thorshammer and the Southern Empress, escaped a pirate voyage by the German auxiliary cruiser Pinguin in January 1941 . Several other ships of the class were lost in World War II, but three survived after 1945. Two of them were demolished in the 1950s, including the San Melito , the only ship that remained with Eagle Oil throughout its service life . The last ship that started its voyage to the scrapping yard was the Norwegian whale-boiling Thorshammer , the former San Nazario . It reached the CN Santa Maria demolition plant in La Spezia on September 6, 1962.
technology
When they were built, the ships were the largest tankers in the world. They had 24 cargo tanks, which were divided with longitudinal and transverse bulkheads. The tanks could be heated with heating coils so that viscous oils could also be transported. The pump output was 1200 tons per hour. The boilers of the ships with steam engine propulsion were notably fired with coal, despite the oil cargo. The speed of the San Fraterno tankers was around ten knots.
