SS Aberdeen (1881)

SS Aberdeen was a British cargo liner completed in 1882. She was designed for service from London to Australia, and was the first ship to be successfully powered by a triple expansionsteam engine. The triple expansion engine very quickly became the standard choice for the entire industry, with its predecessor, the two cylindered compound engine virtually ceasing to be built by 1885. The fuel economy achieved meant that steam propulsion was able to outcompete sail on all major commercial routes.

Aberdeen was sold in 1906 to the Ottoman government and renamed Halep. She served as a Turkish troopship in World War I before being sunk by a British submarine in 1915.
