  1. 1. Monitoring marine alien and invasive species. A comparison between the traditional method (eRAS) and DNA-based identification of species.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Josefin Holm; [2023-08-22]
    Nyckelord :;

    Sammanfattning : There is a major concern with the uncontrolled spreading of alien and invasive species, caused by an increase in travelling by boat globally. These are dispersed via ballast water, by fouling on ships and in fishing gear. LÄS MER

  3. 2. Techniques for characterization and quantification analysis of foulant deposition in Alfa Laval’s high-speed separators : A literature study

    Kandidat-uppsats,

    Författare :Mwansa Benaya; Henrik Dahlén; Emil Axelsson; Cassandra Liljekvist; Maja Nordell; [2022]
    Nyckelord :Dairy foulant; Marine foulant; Characterization; Quantification; Stainless steel; surface; analysis;

    Sammanfattning : Alfa Laval is a global company that provides solutions, products, and services for industry, such as high-speed separators for marine and food-application. Foulant deposition on the stainless-steel surfaces of Alfa Laval’s high-speed separators has shown to result in lowering of the separation efficiency. LÄS MER

  4. 3. Floating Terminal: Technical Lifetime of 60 Years

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Henrik Lindholm; [2021]
    Nyckelord :Corrosion; Fouling; Fatigue; Korrosion; Beväxning; Utmattning;

    Sammanfattning : Offshore solutions for container infrastructure such as Sea Technologies' floating container terminal can bring both environmental benefits and transport efficiencies for shipping.Large investment costs and requirements for long-term operational reliability for such structures entail the need for long technical service life.

  5. 4. Isolation and genomic characterization of three PHA degrading bacteria from the marine environment

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Giulia Elli; [2019]
    Nyckelord :PHA; degradation of PHA; marine bacteria; sulphate reducing bacteria; SRB; SRM; biotechnology; bioteknik; Technology and Engineering;

    Sammanfattning : The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. LÄS MER

  7. 5. Super Duplex Stainless Steel Surfaces and their Effects on Marine Biofouling

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Adrian Falk; [2017]
    Nyckelord :Marin tillväxt; superduplex; bottenfärg; havstulpaner;

    Sammanfattning : Some of the world’s most ancient, but still viable, organisms have since the beginning of maritime caused problems for the industry. The problems affect both the longlivety and efficiency of ships which is caused by the mere presence of organisms attached to the ship hulls. LÄS MER
