Abstract

En offshoreplattform (10) er beskre-vet for midlertidig bruk av en oppjek-kingsrigg (34) for brønnoperasjoner på dypt vann, med en bunnfundert understells-bunn (12) som støtter et overflatetårn ( 28 ) som strekker seg over vannflaten (30) og en undersjøisk riggstøtteovergang (110) som støtter oppjekkingsriggen (34) for brønnoperasjoner. Minst én av de selektive oppdriftstanker (112) for riggstøtten er forbundet til riggstøttens overgang hvor en del av den midlertidige belastning på understellsbunnen som støtter oppjekkingsriggen for boring, kan avlastes.
