The SS Oslo was a British passenger steamship constructed in 1906 by Earle's Shipbuilding & Engineering Co. in Hull, United Kingdom. Built with yard number 515, she was launched on April 9, 1906, and completed by May 19 of the same year. The vessel measured 88.4 meters (290 feet) in length, with a beam of 11.9 meters (39 feet 1 inch) and a depth of 7.7 meters (25 feet 3 inches). Her steel hull featured a forecastle that extended 10.9 meters (35 feet 9 inches) and was equipped with a single funnel and two masts. The ship's construction included two decks, water ballast tanks, and was fitted with electric lighting, highlighting her modern amenities for the period. Propelled by a triple expansion steam engine with three cylinders measuring 0.55, 0.9, and 1.52 meters in diameter, the SS Oslo achieved a maximum speed of approximately 13½ miles per hour (around 13 knots) during sea trials on May 12, 1906. The engine, rated at 233 nominal horsepower, was produced by the same company responsible for her hull. Her propulsion system drove a single screw propeller. The vessel's passenger accommodations included capacity for 95 first-class, 32 second-class, and 90 third-class passengers, with provisions for around 410 additional steerage passengers in temporary berths, reflecting her role as a passenger liner for Norwegian routes. Initially built for the Christiania route (now Oslo), she also served on other routes, including Trondheim to Hull, from 1911 onward. Her last voyage from Christiania was on March 20, 1915. Notably, SS Oslo survived an attack in October 1915 by managing to outrun her attacker. However, her service ended tragically when she was torpedoed and sunk by the German submarine SM U-87 on August 21, 1917, while en route from Trondheim to Liverpool with passengers and copper ore cargo. The attack occurred in the North Sea, 15 nautical miles east by north of the Out Skerries, Shetland Islands, and resulted in her sinking to a depth of over 88 meters. Her wartime service and sinking mark her as a vessel involved in the maritime conflicts of World War I, illustrating the dangerous environment faced by passenger ships during this era.
