Oy Lehtoniemi Ab was a Finnish engineering and shipbuilding company, which operated in 1902–1930. The yard was located in Lehtoniemi, Joroinen in Mikkeli Province at lake Saimaa. The company was founded by Carolus Wrede to continue operations of the previously bankrupted Tehtaat Lehtoniemi & Taipale Fabriker. He restarted the business under the same name. Wrede invested on facilities and the business became flourishing again. The company form became limited liability company Oy Lehtoniemi Ab in 1917 and the ownership base was extended. The portfolio consisted ships, steam boilers, steam engines and pumps. A large part of the customers were from Imperial Russia and later Soviet Union. Oy Lehtoniemi Ab was discontinued in 1930 and itse premises were sold to A. Ahlström Oy. The facility was closed down in 1951. Background Start of shipbuilding in Lehtoniemi dates back to late 1880s, when engineer Torsten Forstén bought a piece of land and started building ships together with his business partner Albert Krank. Krank had already started his business in 1886 in a leased area next to Taipale channel. The company name became Tehtaat Lehtoniemi & Taipale Fabriker. The first ship, called Salmi, was completed in 1889; in the following year two other ships, Suvas and Kalla, were built for the same customer. The quality was high and the order intake raised. Forstén left the company in 1892, after which Krank led the business alone; he was an innovative and enthusiastic engineer, who got many patents. Large part of the production went to Russia. In 1896 the company built a paddle steamer for a Moscow-based customer, and icebreaker Jermak, which went to Vladivostok; both ships were delivered in parts and assembled in Russia; they were too large to fit into the Saimaa Canal. The company built also its own fleet, which comprised about ten vessels. The ships transported freight and tugged barges and logs. The company bankrupted in 1901 due to economical recession and Krank died in the following year. Re-establishment The premises were bought by Freiherr Carolus Wrede on 15 September 1902. He restarted the operations under the same name, Tehtaat Lehtoniemi & Taipale Fabriker. Wrede appointed engineer Harald Staffans as Technical Manager and invested on the facility modernising the plant. Subsequently, the yard experienced a new upswing. In 1910 a new roller slipway with a winch was completed. A large state-of-art equipped workshop for boilers followed in 1914. The timber used
