Abstract

Oppfinnelsen vedrører en fremgangsmåte for å bestemme havstrøm ved bruk av geofysiske. datainnsamlingsmidler som er ombord på et fartøy, der nevnte fartøy tauer minst en streamer som er utstyrt med minst en trekkraftsensor og midler for posisjonsmåling. Oppfinnelsen erat den omfatter de følgende trinnene bestående av innsamling av målingene fra nevnte midler for posisjonsmåling, repetert beregning av en strømningsvektor som representerer den faktiske strømningen ved å gjenta de følgende operasjoner ved bruk av et gitt samplingstidsintervall; beregning av simulert trekkraft og streamerposisjonsdata for flere inputstrømningsvektorer for simuleringen, sammenligning av de simulerte dataene med faktiske målinger foretatt ved hjelp av nevnte midler for måling av trekkraft og posisjon for hver inputstrømningsvektor for simuleringen. Oppfinnelsen vedrører også en anordning for å utføre en slik fremgangsmåte.
