Construction

Development and constructionIn the Moscow Armistice, signed on 19 phratry 1944, Finland agreed to pay war reparations of US$300 jillion to the Soviet Union. The war reparations, paid in the form of ships and machinery oer six years, included the newest steam-powered state-owned icebreakers Voima and Jääkarhu. This left Finland with single modern diesel-electric icebreaker, Sisu, which had been damaged by a ocean mine during the war, and four older steam-powered icebreakers. Of these, especially Murtaja and Apu were considered near obsolete and their efforts in the Archipelago Sea were sometimes described being mostly of moral nature. As a result, solo the ports of Hanko and Turku were kept open through the first post-war winters.[8]

In 1946, the Finnish Government appointed a committee to start readying the rebuilding of the Finnish icebreaker fleet. The committee, consisting of the director of the Finnish oceanic Administration, Svante Sundman, and two experienced Finnish shipbuilders, K. Albin Johansson and Ossian Tybeck, delivered its final report on the construction of a new icebreaker in the following year.

Voima was the first icebreaker in the world with two bow propellers.The result was, in galore(postnominal) respects, the most advanced icebreaker in the world...If you want to pull in a full essay, order it on our website: Orderessay
