Abstract

Oppfinnelsen vedrører en fremgangsmåte for montering og demontering av en installasjon som befinner seg på havbunnen, f.eks. en rørledning (1) liggende på havbunnen (2), hvor komponenter, f.eks. rørflenser (5,6) er innbyrdes festet ved hjelp av mutter- og boltforbindel-ser (7), og mutter- og boltforbindelsene (7) løsnes og/eller festes ved hjelp av en skrunøkkel (30). Mutter- og boltforbindelsene (7) blir her løsnet av dykkere som bruker en skrunøkkel (30). Dette er tungt og vanskelig arbeide. Det er umulig for dykkere å operere på betydelige dyp. Kompliserte og meget kostbare rørledningsforbindelser anvendes derfor som kan løsnes og festes uten dykkere. Oppfinnelsen har som formål å redusere de nevnte ulemper ved den kjente fremgangsmåte. For dette formål anvendes minst én skrunøkkel (30), der en inngrepskopp (32) for inngrep med en mutter (35) og/eller et bolthode i aksial retning av en mutter- og boltforbindelse for manipu-lering, er forskyvbar i forhold til en koppbærer mot en fjærvirkning.
