2. 11. Retrieval of Ocean Surface Currents and Winds Using Satellite SAR backscatter and Doppler frequency shift

   Author : Anis Elyouncha; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Doppler centroid analysis; Bayesian inversion; ocean surface winds; Ocean surface currents; synthetic aperture radar; along-track InSAR;

   Abstract : Ocean surface winds and currents play an important role for weather, climate, marine life, ship navigation, oil spill drift and search and rescue. In-situ observations of the ocean are sparse and costly. Satellites provide a useful complement to these observations. READ MORE

4. 12. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction

   Author : Kadir Burak Korkmaz; Chalmers tekniska högskola; []
   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; numerical friction line; form factor; CFD; measurement uncertainty; power prediction; EFD; verification and validation; Combined CFD EFD Methods;

   Abstract : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.

5. 13. Management of ship-generated waste - illustrated from the Baltic Sea perspective

   Author : Magda Wilewska-Bien; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; shipping; fly ash; Baltic Sea; food waste; nutrients; leaching;

   Abstract : Globally around one-third of food produced for human consumption is wasted or lost. Although the food waste issues on land are being widely discussed, the food waste generated on ships seems not to receive similar attention. READ MORE

6. 14. Energy Performance and Manoeuvring Modelling of Inland Waterway Vessels

   Author : Chengqian Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; confinement effect; inland waterways; manoeuvring prediction; autonomous vessels; ship hydrodynamics; energy efficiency;

   Abstract : Inland waterway transport has significant potential to reduce greenhouse emissions and road congestion safely and sustainably. To construct competitive, intelligent waterborne transport networks, the use of advanced vessels with clean energy and a high degree of automation or autonomy is an ideal solution for next-generation transport.

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

   Author : Artjoms Kuznecovs; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE
