2. 1. Analysis of the Fatigue Characteristics of Mooring Lines and Power Cables for Floating Wave Energy Converters

   Author : Shun-Han Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mooring line; power cable; fatigue; coupled analysis; power absorption; experiment; wave energy converter; heaving point absorber; computational modelling; marine biofouling effect on fatigue;

   Abstract : 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. READ MORE

4. 2. Wave energy conversion and the marine environment : Colonization patterns and habitat dynamics

   Author : Olivia Langhamer; Anders Berglund; Jan Sundberg; Andrew Gill; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial reefs; benthos; biodiversity; biofouling; colonization; environmental impact; fish; shellfish; Mytilus edulis; renewable energy; wave power; Biology; Biologi; Animal Ecology; Zooekologi;

   Abstract : A wave energy park has been established on the Swedish west coast outside Lysekil and pioneer work about its interactions with the marine environment has been conducted. So far, little is known about the effects of offshore energy installations on the marine environment, and this thesis assists in minimizing environmental risks as well as in enhancing potential positive effects on the marine environment.

5. 3. The Enemy Below - Adhesion and Friction of Ship Hull Fouling

   Author : Dinis Oliveira; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship resistance; in-water hull cleaning; roughness; biofouling; hull grooming; frictional resistance; adhesion strength; turbulent boundary layer; hull form factor;

   Abstract : Below the waterline, commercial ships are good targets for marine organisms to attach and proliferate, a problem commonly known as biofouling. A fouled hull means higher hydrodynamic resistance, which can result in significant fuel penalties. READ MORE

6. 4. Barnacle Bioadhesive Bonding Formation, Strength and Control

   Author : Mattias Berglin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barnacle adhesive plaque; poly dimethylsiloxane ; fouling release coatings; bioadhesion; marine biofouling;

   Abstract : The current technology for keeping ship hulls free of marine biofouling requires the use of toxic compounds such as copper, organic biocides and tributyl tin (TBT). The compounds that are released have been shown to have negative effects on non-target organisms, and a worldwide ban of TBT is currently being introduced. READ MORE

7. 5. New Perspectives in Multi-trophic Aquaculture

   Author : Matthew Hargrave; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquaculture; kelp; seaweed; IMTA; mussel; bioremediation; Saccharina latissima; Mytilus edulis; extractive aquaculture; biofouling; epiphytes;

   Abstract : Aquaculture, the farming of marine and aquatic organisms, is currently the fastest growing food production sector globally. As capture fisheries have stagnated and the fishing down of marine food webs has been seen to be unsustainable, aquaculture is filling the deficit in providing food to a growing world population.
