Abstract

Et offshore overvåkningssystem for en elektrisk kraftkabel koplet mellom et fast punkt og bevegelig punkt, eller for en elektrisk kraftkabel som kopler sammen to bevegelige punkter. Systemet omfatter minst en optisk fiber som virker som en kontinuerlig distribuert deformasjonsmålesensor festet til eller arrangert i nevnte kraftkabel, en innretning arrangert for å sende optiske signaler og en innretning arrangert for å motta optiske signaler for å bestemme den tidsvariable bøying av nevnte kraftkabel.
