Abstract

Stabiliseringssystem (10) for stabilisering av en undersjøisk rørledning (11) på en havbunn (13) under vannflaten. Havbunnen (13) heller ved at den i nnbefatter et hellende eller skrånende avsnitt (15) mellom et øvre avsnitt (16) og et nedre avsnitt (17). Stabiliseringssystemet (10) innbefatter et øvre forankringsmiddel (21) for forankring av rørledningen (11) til det øvre havbunnsavsnittet (16) ved den øvre enden av det hellende avsnittet (15), mens det andre forankringsmidlet er et nedre forankringsmiddel (22) for forankring av rørledningen (11) til det nedre havbunnsavsnittet (17) ved bunnenden til det hellende havbunnsavsnittet (15). Det er anordnet oppdriftsmidler (23) langs rørledningsavsnittet (11a) mellom de to forankringsmidlene (21, 22). Den oppdriften som tilveiebringes ved hjelp av oppdriftsmidlene (23), er tilstrekkelig til å holde røravsnittet (11a) over og fri for kontakt med det hellende havbunnsavsnittet (15).
