17. Analysis of the Fatigue Characteristics of Mooring Lines and Power Cables for Floating Wave Energy Converters
Sammanfattning : To reduce greenhouse gas emissions and expand the energy mix, there is a pressing need for the exploitation of renewable sources of energy, such as biomass, hydropower, solar power, waves, and wind. This thesis focuses on ocean wave energy and its applications. LÄS MER
18. Influence of deformation and environmental degradation of Inconel 792
Sammanfattning : Industrial gas turbines are often used as a mechanical drive for pumps and compressors or in power generation as an electric power supply. The gas turbine has for many years been a popular engine due to its flexibility with respect to different types of fuel and due to a design, that enables a high power-to-weight ratio. LÄS MER
19. Development of voyage optimization algorithms for sustainable shipping and their impact to ship design
Sammanfattning : The environmental impacts from shipping and the societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry to improve its energy efficiency and enhance ship safety. Voyage optimization is such an effective measure that has been widely adopted in today’s shipping market. LÄS MER
20. Numerical prediction of propeller induced hull pressure pulses and noise
Sammanfattning : An operating marine propeller is one of the major sources inducing hull pressure pulses, onboard noise and vibration as well as underwater radiated noise. There are rising concerns of environmental impacts and comfort and welfare of passengers and crews due to these negative effects. LÄS MER
