    • Pipeline Liquid Control using Nonlinear MPC and OLGA: Optimal Utilization of Available Liquid Buffer Volume during Pipeline Transients 

      Torpe, Håvard (Master thesis, 2007)
      Pipelines with multiphase flow will exhibit large and highly nonlinear liquid rates during transients caused by changes in production rate. This requires either a large separator (slug catcher) downstream, capable of ...
    • Estimering av TNS-parametre og -ytelse 

      Skorpen, Roger (Master thesis, 2007)
      Undervannsbåter er avhengige av et treghetsnavigasjonssystem (TNS) for å kunne beregne egen posisjon når de er neddykket. Denne oppgaven vil se nærmere på et skrogfast TNS som er i bruk på de norske undervannsbåtene av ...
    • Optimalisering av LNG-verdikjeden 

      Dahl, Kristoffer (Master thesis, 2007)
      Hovedmålet i hovedoppgaven er å utvikle en effektiv metode for å optimalisere driften av Statoils LNG anlegg ved uforutsette hendelser som forsinket skipsankomst og problemer med en produksjonsbrønn.
