1. Improving Ship Energy Efficiency through a Systems Perspective
Sammanfattning : The last years have been particularly challenging for the shipping industry. Fuel prices have increased to levels only seen during the oil crisis in the 70's, and environmental regulations have grown much stricter than in the past. Climate change, at a global level, is going to become a major threat to society. LÄS MER
2. The social organization of energy efficiency in shipping: a practice-based study
Sammanfattning : The central research question explored in this study is how energy efficiency is organized onboard large merchant ships. The dominant techno-economical approach within energy research and policy, in general, and shipping research and policy, in particular, is reviewed and criticized as being too limited for understanding the challenges and opportunities related to the organization and management of energy efficiency in shipping companies.

3. A Generic Model for Simulation of the Energy Performance of Ships - from Early Design to Operational Conditions
Sammanfattning : Forecasts show a doubling of the world’s transportation needs until 2050. Shipping today accounts for 90% of all freight transport. Simultaneously, shipping must become cleaner and more energy-efficient to meet the target to more than halve 2005 greenhouse gas emissions by 2050. LÄS MER
4. Simulation model of a ship’s energy performance and transportation costs
Sammanfattning : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.

5. Voyage optimization algorithms for ship safety and energy-efficiency
Sammanfattning : Currently, over 90% of the world’s trade is transported by sea. The environmental impacts from shipping and societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry for more energy efficiency and enhanced safety. LÄS MER
