  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. 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.

  5. 4. Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Maria Nicte Polanco Olsen; [2018]
    Nyckelord :;

    Sammanfattning : I närvaro av fukt och lokaliserade fältförbättringar kan vattenträd utvecklas inom polymerisoleringen av HV subsea kraftkablar. Vattenträd tenderar att växa obemärligt och försämra isolationsegenskaperna med tiden. Fuktigheten i isoleringen kan effektivt reduceras genom applicering av halvledande svällningsband. LÄS MER

  7. 5. Short-circuit Contributions from Fully-rated Converter Wind Turbines : Modeling and simulation of steady-state short-circuit contributions from FRC wind turbines in offshore wind power plants

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektriska energisystem

    Författare :Joakim Ahnlund; [2014]
    Nyckelord :;

    Sammanfattning : In recent years there has been an increase in wind power plants installed out at sea. The generated power of wind turbine generators (WTGs) are collected through numerous subsea cables into a single hub, the offshore platform. Subsequently, this platform is interconnected with the onshore main grid through a further stretch of cable. LÄS MER
