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.One method concerns the joining of the superstructure to a floating offshore structure, e.g. a Save hull, joining the components of a Save hull (10) and a combination or variants of these procedures. In general, the installation is carried out as follows: At the point where merging is to take place, the Spar hull component (10) is raised, equipped with controls and devices necessary to perform a controlled immersion of the Spar hull component (10) and it is submerged. to a predetermined depth below the water surface so that a zero-water plane area appears. The second component (26) to be joined with the top of the Spar hull (10) is caused to float over the submerged Spar hull component (10). The draft of the submerged Spar hull component (10) is reduced until the two components (10,26) come into full operation.
