  1. 1. Ship Behaviour and Ship Bridge Allision Analysis

    Author : Axel Hörteborn; SSPA Sweden AB; []
    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; ship domain; ship simulations; AIS data; failure statistics; risk modelling;

    Abstract : 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. READ MORE

  2. 2. Rigid Body Ship Dynamics

    Author : Martin Alexandersson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Rolf Skjong; Försvarshögskolan; []
    Keywords : 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;

    Abstract : 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.

  4. 4. Efficient Full-Scale CFD for Ship Hydrodynamics

    Author : Michal Orych; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

  5. 5. Ship and Society : Maritime Ideology in Late Iron Age Sweden

    Author : Gunilla Larsson; Ola Kyhlberg; Mats G. Larsson; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Archaeology; Ships; Seafaring; Society; Late Iron Age; shipbuilding methods; symbols; sacrifices; boat burials; ideology; leiðangr; long distance journeys; river routes.; Arkeologi; Archaeology; Arkeologi;

    Abstract : This thesis analyses the relation between ship and society against a background of ideological and technological changes in Late Iron Age Sweden. It discusses the factors behind the development of ‘a maritime society’, why ships and seafaring came to play an important role that was also reflected in the use of the ship as a symbol and a metaphor in a military context, as well as in religion, administration, jurisdiction and social life.
