1. 16. Ergonomics: An uncharted route to improved overall systems performance in shipping

   Författare :Cecilia Österman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ergonomics; human factors; quality; safety.; productivity; shipping; efficiency;

   Sammanfattning : Continuously, improved design of hull, propulsion and cargo handling systems has increased speed, capacity and reliability of sea transports. Simultaneously, efforts have been made to perfect crew size and composition in order to optimize operations costs. LÄS MER

3. 17. Reducing ships' fuel consumption and emissions by learning from data

   Författare :Fredrik Ahlgren; Marcus Thern; Maria E. Mondejar; Cecilia Österman; Ann-Charlotte Larsson; Erik Dahlquist; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shipping; energy efficiency; orc; machine learning; emissions; Sjöfartsvetenskap; Maritime Science;

   Sammanfattning : In the context of reducing both greenhouse gases and hazardous emissions, the shipping sector faces a major challenge as it is currently responsible for 11% of the transport sector’s anthropogenic greenhouse gas emissions. Even as emissions reductions are needed, the demand for the transport sector rises exponentially every year. LÄS MER

4. 18. Saving energy at sea: seafarers’ adoption, appropriation and enactment of technologies supporting energy efficiency

   Författare :Martin Viktorelius; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy performance monitoring; shipping; seafarer.; workplace studies; ethnography; energy efficiency; maritime human factors; digitalization; practice-based; automation; sociomaterial;

   Sammanfattning : The shipping industry is currently facing a major challenge related to environmental sustainability and energy efficiency. New regulations and ambitious international goals that aim at mitigating carbon-based emissions with 50 %, demands on profitability, along with a growing awareness about the climate change, has prompted the maritime sector to increasingly focus on how to improve energy efficiency and reduce fuel consumption in ship operations.

5. 19. Controlling the Roll Responses of Volume Carriers

   Författare :Carl-Johan Söder; Anders Rosén; Jan De Kat; KTH; []
   Nyckelord :PCTC; parametric roll; roll response; roll damping; rudder control; aerodynamic roll damping; roll mitigation; racking; Ikeda’s method; CFD; model tests; Full-scale tests; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : Modern volume carriers such as container vessels, cruise ships and Pure Car and Truck Carriers (PCTC’s) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this doctoral thesis aims at enhancing the predictability and control of these critical roll responses. LÄS MER

7. 20. A Life on the Ocean Wave - Exploring the interaction between the crew and their adaption to the development of the work situation on board Swedish merchant ships

   Författare :Monica Lundh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine room; evacuation; work environment; Keywords: Automation; role conflict; ships; stress; engine officers;

   Sammanfattning : ABSTRACTWorking on board merchant ships implies being a part of an isolated context in a multi-cultural arena and spending a lot of time away from family and friends. The shipping industry has during the latest decades undergone major changes due to technical development, automation and increased requirements for profitability and competitiveness. LÄS MER
