  • Built to Break the Larger Classes of Container Project Manager at Arctech

The idea is for the ship to be able to make headway in ice up to 60 centimetres thick, while carving a channel 50 metres wide – enough for large container ships to follow. The asymmetric hull has a major drawback, though. Modelling shows that it will pitch and roll irregularly at sea, and “Rotating thrusters allow the asymmetric ship to swing round and attack the ice at an angle” pilots will have to learn how to sail the vessel to compensate. “There are lots of different operational modes for the ship, –Well, steer me sideways– all of which had to be addressed when working out how to use able to punch channels about the power from each of the three 25 metres wide – too narrow for thrusters,” says Mika Willberg, Built to break the larger classes of container project manager at Arctech. ships.

  • Reform, Foreign Technology, and Leadership in the Russian Imperial and Soviet Navies, 1881–1941
    REFORM, FOREIGN TECHNOLOGY, AND LEADERSHIP IN THE RUSSIAN IMPERIAL AND SOVIET NAVIES, 1881–1941 by TONY EUGENE DEMCHAK B.A., University of Dayton, 2005 M.A., University of Illinois, 2007 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Department of History College of Arts and Sciences KANSAS STATE UNIVERSITY Manhattan, Kansas 2016 Abstract This dissertation examines the shifting patterns of naval reform and the implementation of foreign technology in the Russian Empire and Soviet Union from Alexander III’s ascension to the Imperial throne in 1881 up to the outset of Operation Barbarossa in 1941. During this period, neither the Russian Imperial Fleet nor the Red Navy had a coherent, overall strategic plan. Instead, the expansion and modernization of the fleet was left largely to the whims of the ruler or his chosen representative. The Russian Imperial period, prior to the Russo-Japanese War, was characterized by the overbearing influence of General Admiral Grand Duke Alexei Alexandrovich, who haphazardly directed acquisition efforts and systematically opposed efforts to deal with the potential threat that Japan posed. The Russo-Japanese War and subsequent downfall of the Grand Duke forced Emperor Nicholas II to assert his own opinions, which vacillated between a coastal defense navy and a powerful battleship-centered navy superior to the one at the bottom of the Pacific Ocean. In the Soviet era, the dominant trend was benign neglect, as the Red Navy enjoyed relative autonomy for most of the 1920s, even as the Kronstadt Rebellion of 1921 ended the Red Navy’s independence from the Red Army.

  • Transas Group Installed State-Of-The-Art Equipment on the Unique Baltika Icebreaker
    Transas Group installed state-of-the-art equipment on the unique Baltika icebreaker April 23, 2014 –Finland. The world's first oblique icebreaker equipped with Transas navigation and communication equipment has successfully completed sea trials. Baltika icebreaker, built at the Russian-Finnish Arctech Helsinki Shipyard Oy is an asymmetric- hull icebreaker intended for oil spill response and rescue operations. It is capable to operate in one-meter thick ice and opening an up to 50 meters wide channel in ice. Within the project, Transas has supplied and commissioned an integrated navigation system, a set of Nav/Com and CCTV equipment, as well as VHF equipment for helicopter take-off and landing support. All equipment is operable at Arctic latitudes at a temperature of -400С. In addition, Transas has installed state-of-the-art satellite communication systems meeting high technical requirements set for the multifunctional vessels of this class. Dmitry Lagoutin, managing director of Transas Navigator Ltd (part of the Transas Group) comments: "Transas continues its strategic cooperation with European shipbuilders. The Baltika icebreaker is our third major project with the Arctech Helsinki Shipyard, following two other successful newbuilds - Arctic supply vessels Vitus Bering and Alexei Chirikov, delivered to JSC Sovcomflot. The Baltika icebreaker is the first vessel with a non-standard hull shape where Transas has installed ECDIS with a track control system". The icebreaker was built for the State marine emergency salvage, rescue and pollution prevention coordination service of the Russian Federation (SMPCSA). The unique vessel's design was developed by the Aker Arctic Technology (Finland), the hull was built by the JSC Shipyard «Yantar», and final assembly was carried out at the Finnish Arctech Helsinki Shipyard Oy.

  • The Russian Maritime Industry and Finland Hanna Mäkinen
    Hanna Mäkinen The Russian maritime industry and Finland Electronic Publications of Pan-European Institute 2/2015 ISSN 1795 - 5076 The Russian maritime industry and Finland Hanna Mäkinen 2/2015 Electronic Publications of Pan-European Institute http://www.utu.fi/pei Hanna Mäkinen PEI Electronic Publications 2/2015 www.utu.fi/pei Executive summary 1) Due to historical reasons, the civil shipbuilding industry is weakly developed in Russia and is currently not competitive in commercial sense. The Russian shipyards are in a rapid need of modernisation and the shipbuilding industry suffers from low productivity and technological inferiority compared to other shipbuilding nations. In order to improve the industry’s competitiveness, international cooperation is needed. 2) The Russian maritime industry has recently received increased political attention and funding. Particularly the growing interest in the Arctic hydrocarbon fields and sea routes as well as the continuous importance of energy exports for the Russian economy have boosted the development of the shipbuilding sector. In addition, as Russia has engaged into rearmament, the demands of the Russian navy significantly direct the development of the Russian maritime industry. 3) The current unstable political and economic situation, particularly the ruble’s decline against the euro, the plunge in world oil prices and the economic sanctions imposed on Russia, have complicated the implementation of maritime and offshore industry projects in Russia. The sanctions have a negative impact on the Russian shipbuilding and offshore industries as they complicate companies’ possibilities to attract foreign financing and prohibit exports of products and services and technology transfer to Russia if they are related to defence and oil industries.

Although sea ice. The oblique mode, which had Baltika was designed to operate primarily in the Gulf of Finland, never been tested before in real life, also she was taken to the Gulf of Ob, where the ice conditions are worked extremely well and the vessel more challenging than in the Baltic Sea, for ice trials. fulfilled all the design requirements. Baltika's maiden voyage began at her home port, St. Petersburg, on 6 March 2015. While on her way to Murmansk off the coast of Norway, the vessel encountered rough seas and winds up to 30 m/s. The seakeeping characteristics of the oblique icebreaker were good, and the owner was convinced thatBaltika is able to take part in rescue operations even in harsh weather. Ice trials "We departed for the ice trials from Murmansk on 20 March 2015 and sailed around the northern tip of Novaya Zemlya to the Gulf of Ob and close to the Sabetta terminal area," project manager Mika Hovilainen says. "Our purpose was firstly to demonstrate the vessel's abilities Ice trials were conducted in the Gulf of Ob during the worst winter conditions. The during the worst part of the year, and voyage took three weeks in total. secondly to perform official ice trials."

  • 50 Years of Ice Model Testing Creating a Testing Platform for Inventive Designs
    Aker Arctic A Success Story 50 of Finnish Technology years of ice model testing The Ice Technology Partner 50 years of ice model testing Creating a Testing Platform for Inventive Designs Year 2019 marks 50 years since the first ice model testing project in Finland which revolutionized the design process of ice-going vessels. The first ice model testing series have proven to be essential to the design process of ice going vessels and the operation in the first provisional facility was continued. The following model testing facilities were dedicated to ice model testing which is crucial design tool in ice technology. Many development projects which initially sounded unrealistic would not have been possible without ice model testing. For example, the DAS™ concept, the Oblique icebreaker, or the Arctic LNG carriers could not have been realized without extensive In the 1990s there arose a need for an verification of the ideas' feasibility icebreaker which would create a wide through model tests.
