  2. 1. Sustainable Kelp Aquaculture in Sweden

    Author : Wouter Visch; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biofouling; cryopreservation; ecosystem services; environmental impact; extractive aquaculture; gametophytes; kelp; population diversity; Saccharina latissima; seaweed cultivation; selective breeding; site selection;

    Abstract : Seaweed aquaculture is gaining more interest worldwide, including Europe. However, despite its long coast seaweed farming is still very minor in Sweden. 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. Roughest hour – approaches to ship hull fouling management

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

    Abstract : Submerged surfaces at sea are colonized by a high diversity of sessile (i.e. attached) life forms. As the merchant fleet capacity increases, responding to growth in demand for seaborne transport, so does the hull wetted surface area that is prone to colonization by these sessile organisms, i.

  7. 5. Enabling a Robot for Underwater Surface Cleaning

    Author : Houssam Albitar; Amy Loutfi; Anani Ananiev; Mikael Ekström; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; underwater robot; underwater cleaning; biofouling; adhesion; locomotion; stability; Reglerteknik; Automatic Control;

    Abstract : Biofouling build-up on submerged structures such as ships, petroleum and gas storage tanks, electric power plants, bridges, oil rigs etc. is a major problem that affects the surface material of the structure, the eventual hydrodynamic quality of the surface and in some cases the efficacy of cooling systems.
