11. Numerical Investigation of Ship Responses in Calm Water and Regular Head Waves
Sammanfattning : In order to design fuel efficient ships and install right machinery onboard, ship designers need to know the interaction effects between hull, propeller and appendages in realistic operating conditions. Neglecting the interaction effects may result in under/over-prediction of the required power. LÄS MER
12. 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
13. Characterising turbulent ship wakes from an environmental impact perspective
Sammanfattning : The world’s oceans, especially coastal areas, are intensively trafficked by ships. All these ships exert pressure on the marine environment, through emission to the atmosphere, discharges of pollutants to the water, and physical disturbance through energy input. Of these impacts, energy pollution from shipping has received the least attention. LÄS MER
