  1. 1. 1900-talets fartygsarkitektur i Sverige

    Författare :Hans Åkerlind; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Art history; ship; ship-building; ship architecture; Konstvetenskap; Art; Konstvetenskap; konstvetenskap; History Of Art;

    Sammanfattning : The dissertation is divided into four separated parts.Part 1 is a summary of the three following parts, supplemented with components from a more general point of view.Part 2 deals with the shaping of sea-going vessels, delivered between 1935 and 1995. All of them with some form of connection to Sweden. LÄS MER

  3. 2. Ship Behaviour and Ship Bridge Allision Analysis

    Författare :Axel Hörteborn; SSPA Sweden AB; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship domain; ship simulations; AIS data; failure statistics; risk modelling;

    Sammanfattning : The demand for maritime transport has increased with the growing demand for worldwide trade. This has led to a major increase in maritime traffic and ship sizes over the last decades, which raises the probability of accidents. LÄS MER

  4. 3. Rigid Body Ship Dynamics

    Författare :Martin Alexandersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse dynamics; Extended Kalman filter; Ship digital twin; Ship manoeuvring; RTS smoother; Multicollinearity; System identification;

    Sammanfattning : It is common today that operational data is recorded onboard ships within the Internet of Ships (IoS) paradigm. This enables the possibility to build ship digital twins as digital copies of the real ships. Predicting the ship’s motions with ship dynamics could be an important sub-component of these ship digital twins. LÄS MER

  5. 4. Risk-based ship security analysis : a decision-support approach

    Författare :Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Rolf Skjong; Försvarshögskolan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; naval ship; piracy; risk-based; risk control options; ship security analysis; survivability; uncertainty analysis; militära fartyg; sjöröveri; riskanalys; sjöfartsskydd; överlevnadsförmåga; Försvarssystem; Military Technology;

    Sammanfattning : The protection of shipping does not come without hazards and threats for military forces, individual civilian ship operators and crews. With particular focus on security threats, this thesis is about how to prepare for such operations without introducing unnecessary risks, i.e., supporting conscious risk-taking related to ship security.

  7. 5. Efficient Full-Scale CFD for Ship Hydrodynamics

    Författare :Michal Orych; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CFD; Self-propulsion; Ship; Verification; Uncertainty; Full-scale; Validation; Seakeeping; Energy-Saving Device; Roughness; RANS;

    Sammanfattning : An efficient numerical approach for ship hydrodynamics, involving a hybrid free-surface potential flow/RANS method, is explored. The work focuses on estimating the delivered power of ships in calm water and in waves, highlighting the benefits of full-scale simulations, particularly for ships with Energy Saving Devices. LÄS MER
