Dynamic response of a floating offshore wind turbine
(Masteroppgave/UIS-TN-IKM/2010;, Master thesis, 2010)The ever increasing demand for renewable energy, combined with limited areas suitable for large wind farms, has put focus on the development of floating wind turbines. In this thesis the dynamic response of a floating ... -
Conception and development of method / apparatus for close-visual inspection of subsea structures in underwater poor visibility condition
(Masteroppgave/UIS-TN-IKM/2010;, Master thesis, 2010)Attempt has been made to demonstrate that in unclear water to zero underwater visibility conditions, where ordinarily, underwater divers would be unable to observe objects, it is easily possible to perform inspections ... -
Presentasjon av risikoanalyse – et tilnærmingsproblem
(Masteroppgave/UIS-TN-IKM/2010;, Master thesis, 2010)En av hovedoppgavene til risikoanalysen er å støtte beslutningstaking. Den største utfordringen er kanskje å støtte beslutningstaking ved å skaffe til rette relevant informasjon. Usikkerhet er fokuset i oppgaven, men den ... -
ANNMD - Artificial Neural Network Model Developer
(Working paper UiS, Research report, 2010-06)This booklet presents software for Artificial Neural Network (ANN) modeling called Artificial Neural Network Model Developer (ANNMD). ANNMD is generic software for a system modeling with ANNs. Its development is based on ... -
Pipelines for development at deep water fields
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)Oil and gas fields are today being developed at water depths characterized as ultra-deep waters, in this report limited to 3500 meters. Pipelines, which are major components of these developments, will experience challenges ... -
Repair methods for damaged pipeline beyond diving depth
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)Mechanical damage of a subsea pipeline is found as one of the most severe concern in management of pipeline integrity. The need to reach and bring the hydrocarbons from the fields located in deep and ultra-deep waters, ... -
Positioning of gas detectors at offshore installations
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)The safety level at offshore installations is considerably influenced by in which degree undesired gas releases are detected. The primary functions of a gas detection system are to detect the presence of gas and inform ... -
Lifting/Installation analysis of spool - Comparison between brace and spreader solution from a structural, operational and economical point of view
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)As large sections of production pipe are lifted and installed, forces act on the structure. If initial analyses of the structural integrity show that the pipe will fail, support elements have to be introduced. The two most ... -
