  3. 12. Turbulent ship wakes and their spatiotemporal extent

    Författare :Amanda Nylund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; shipping; ship wake; turbulence; environmental impact;

    Sammanfattning : Shipping activities occur in almost every part of the global oceans and in intensely trafficked shipping lanes there can be up to one ship passage every ten minutes. All these ships impact the marine environment in different ways through pollution or physical disturbance. LÄS MER

  4. 13. Risk-based ship security analysis – an approach based on civilian and military methods

    Författare :Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Jakob Kuttenkeuler; Försvarshögskolan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; naval ship; piracy; risk-based; risk control options; ship security analysis; Försvarssystem; Military Technology;

    Sammanfattning : The demands on maritime operations today are increasingly higher in terms of control, efficiency and cost. The margins for accidents and security incidents are therefore decreasing. In the area of ship safety the regulations, guidelines and methods have a history and culture of systematic research, development and implementation. LÄS MER

  5. 14. RoPax Ship Collision – a Methodology for Survivability Analysis

    Författare :Per Hogström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; uncertainty analysis; Crashworthiness; sheet metal failure; ship collision; damage stability;

    Sammanfattning : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. LÄS MER

  7. 15. Ultimate and Residual Strength Assessment of Ship Structures

    Författare :Artjoms Kuznecovs; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship structures; collision; corrosion; residual strength; ultimate strength; age-related degradation; nonlinear FEA; Smith method;

    Sammanfattning : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. LÄS MER
