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.An offshore platform (10) is described for the temporary use of a digging rig (34) for deepwater well operations, with a bottomed substructure bottom (12) supporting a surface tower (28) extending above the water surface (30). and a subsea rig support transition (110) that supports the jack-up rig (34) for well operations. At least one of the selective buoyancy tanks (112) for the rig support is connected to the transition of the rig support where a part of the temporary load on the chassis bottom which supports the jack-up rig for drilling can be relieved.
