2. 1. Dynamic Characteristics of Floating Breakwaters

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

   Abstract : 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.

4. 2. Dynamic Rating with Applications to Renewable Energy

   Author : Kateryna Morozovska; Patrik Hilber; Tor Laneryd; Hans Ezz Edin; Adamantios Marinakis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic rating; dynamic line rating; dynamic transformer rating; power transformers; power system optimization; wind farm planning; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Dynamic rating (DR) of power components is a method for assessing real-time capacity of large scale power transmission and distribution devices (commonly: transmission lines, power transformers, underground cables) and using this knowledge for adjusting loading limits of these components. Dynamic rating of power lines or dynamic line rating (DLR) is a pioneering technology in the area of dynamic rating.

5. 3. Non-Linear Vibration and Dynamic Fracture Mechanics of Bridge Cables

   Author : Armando Leon; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cable Vibrations; Non-Linear Vibration; Dynamic Fracture Mechanics; Cable-Stayed Bridges; Dynamic Stress Intensity Factor;

   Abstract : In the present work, the non-linear vibrations and the corresponding dynamic fracture mechanics of cables of cable-stayed bridges are studied. The cables are among the most critical components in cable-stayed bridges and there are different damage sources such as corrosion, vibration, fatigue and fretting fatigue that can significantly affect them, thereby reducing the cable’s service life and even producing their failure.

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

   Author : Shun-Han Yang; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE
