  1. 1. Development of a flexible turntable for storage of subsea cable : A Systems Engineering approach

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Andersson Isac; [2022]
    Nyckelord :Subsea cable; turntable; carousel; flexible solution; resource saving solution; Systems Engineering;

    Sammanfattning : Infrastructure for electricity and telecommunication, such as subsea cables, are critical in modern society. Future estimates also indicate an increased demand. Subsea cables enable the use of offshore wind power farms, transnational energy distribution and global data transfer. LÄS MER

  3. 2. Global buckling of subsea pipelines with DEH cable

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anders Meurk; [2022]
    Nyckelord :Solid Mechanics; Global Buckling; Subsea Pipelines; DEH cable; Hållfasthetslära; Global Buckling; Undervattensrörledningar; DEH kabel;

    Sammanfattning : Hydrates, wax, and other fluids forms in cold subsea pipelines which restrict flow of petroleum products during operation. This thesis analyses the global buckling behaviour of subsea pipelines with Direct Electric Heating cables (DEH) through a combination of analytical and FEM simulations. LÄS MER

  4. 3. Soft Energization and Blackout Recovery of Offshore Wind Farm Export System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Sammanfattning : Power generation of the future will be dominated by renewable energy sources. This is a positive trend as society aims to improve sustainability, energy security, and reduce CO2 emissions. This progress however bears challenges for the power systems of the future. LÄS MER

  5. 4. CABLES DECOMMISSIONING IN OFFSHORE WIND FARMS: ENVIRONMENTAL AND ECONOMICAL PERSPECTIVE

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Omer Al-Sallami; [2021]
    Nyckelord :Offshore wind energy; subsea cables; decommissioning;

    Sammanfattning : Addressing the decommissioning issues is vital to ensure a sustainable and effective process of such an essential part of the project life cycle. While there is a set of good practices and regulations that govern most of the decommissioning activities, the cable decommissioning issue is still in a big debate and often left abandoned at the seabed due to environmental concerns, as justified by most developers.

  7. 5. Modelling the Energy Transition on the Western Isles, Scotland : Scenario analysis to compare future pathways on the island of Lewis and Harris

    Master-uppsats, KTH/Energiteknik

    Författare :Alisdair James Price; [2021]
    Nyckelord :;

    Sammanfattning : Renewable energy potential at a local level is important if communities are to play a role in the wider global energy transition. The following thesis studies the ongoing transition on the island of Lewis and Harris, part of the Western Isles, Scotland. A PLEXOS energy model is constructed, focusing on the island’s electricity system. LÄS MER
