Abstract

En fremgangsmåte angår sammenføring av overbygningen på en flytende offshore konstruksjon som f.eks. et Spar skrog, sammenføyning av komponentene for et Spar skrog (10) og en kombinasjon eller varianter av disse prosedyrer. Generelt sett utføres installasjonen som følger: På stedet der sammenføring skal finne sted, blir Spar skrog- komponenten (10) reist opp, utstyrt med styringer og anordninger som er nødvendig for å utføre en styrt nedsenkning av Spar skrogkomponenten (10) og den blir nedsenket til en på forhånd bestemt dybde under vannflaten slik at det fremkommer et nullvannplan- område. Den andre komponent (26) som skal føres sammen med toppen av Spar skroget (10) bringes til å flyte over den neddykkede Spar skrogkomponent (10). Dypgåendet for den neddykkede Spar skrogkomponent (10) reduseres inntil de to komponenter (10,26) kommer i fullt anlegg.
