    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Simon Lindroth [formerly Tyrberg]; Uppsala universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Measurement systems; Marine technology; Energy conversion; Renewable energy; Energy absorption; Wave resource; Oceanic engineering; Linear generators; Point absorbers; Sea trials; Camera systems; Accelerometers; Offshore experiments; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

  2. 2. Energy from Ocean Waves Full Scale Experimental Verification of a Wave Energy Converter

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Rafael Waters; Uppsala universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; wave energy converter; sea trials; ocean energy; linear generator; point absorber; search coil; wave climate; utilization; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Abstract : A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. READ MORE

  3. 3. Terrain navigation for underwater vehicles

    University dissertation from Stockholm : KTH

    Author : Ingemar Nygren; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : In this thesis a terrain positioning method for underwater vehicles called the correlation method is presented. Using the method the vehicle can determine its absolute position with the help of a sonar and a map of the bottom topography. READ MORE

  4. 4. On the Hydrodynamics of a Monohull Ship in Following and Stern Quartering Seas

    University dissertation from Stockholm : KTH

    Author : Olov Lundbäck; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The demand for high-speed ships has been increasing by the years and high speed monohull ships are in common use for a wide variety of applications from fast general purpose workboats, pilot boats and patrol crafts to large naval vessels and fast ferries. It has been noted that a large number of high-speed monohull ships suffer relatively high risk for seakeeping problems in following seas, such as surf riding, broaching-to and reduced manoeuvrability in following and quartering seas.

  5. 5. Wave Energy Converters An experimental approach to onshore testing, deployments and offshore monitoring

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Liselotte Ulvgård; Uppsala universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; ocean energy; linear generator; measurements; sensors; point absorber; offshore; PTO; force; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The wave energy converter (WEC) concept developed at Uppsala University consists of a point absorbing buoy, directly connected to a permanent magnet linear generator. Since 2006, over a dozen full scale WECs have been deployed at the Lysekil Research Site, on the west coast of Sweden. READ MORE
