1. 1. Analysis of Fatigue Characteristics in Mooring Lines and Low Voltage Cables for Wave Energy Converters

   Författare :Shun-Han Yang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave energy converter; de-coupled analysis; power cable; fatigue; dynamic cable; heaving point absorber; mooring line; coupled analysis; power absorption; marine biofouling effect on absorbed power; low voltage cable; catenary mooring chain; marine biofouling effect on fatigue;

   Sammanfattning : To reduce both carbon emission and fossil fuel consumption, there is a pressing need for the exploitation of renewable sources of energy such as biomass, hydropower, solar power, waves, and wind. This thesis addresses the application of wave energy, which has a large potential to contribute to the world’s renewable emission-free energy supply. LÄS MER

3. 2. POSITION MOORING OF WAVE ENERGY CONVERTERS - An engineering study into the mooring of structures in a highly exposed shallow ocean regime, within the context of the economics of renewable energy conversion

   Författare :John Fitzgerald; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; energy; catenary; articulated tower; ocean; Mooring; wave; anchor; energy;

   Sammanfattning : The principles of systems engineering are applied in order to establish the requirements formooring wave energy conversion devices. These requirements capture both the function ofmaintaining position in energetic wave climates as well as the need to enable an economiclifecycle for the development of a viable wave energy conversion industry.

5. 4. Dynamic Characteristics of Floating Breakwaters

   Författare :Aurora Xiaomeng Lei; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; floating breakwaters; couplings joints ; dynamic cables; dynamic response; line tension; wave attenuation; wave reflection;

   Sammanfattning : The dynamic behaviour of interconnected floating breakwaters has been studied theoretically and experimentally. For this type of shore-protection system, problems that must be dealt with include wave loads on the breakwaters caused by the interaction between the bodies and the waves, motions of the moored breakwaters caused by the waves, changed wave fields in front of and behind the breakwaters, and forces on the mooring cables and in interconnections between breakwater units.

7. 5. Time-domain modeling of a wave power farm

   Författare :Charitini Stavropoulou; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : In this work, we model a point absorber wave energy converter (WEC) very similar to the device that originated and was developed at Uppsala University in Sweden. The device is simulated both as a one- and a two-body model. LÄS MER
