Abstract

Hylse (2) med dobbel tetning for gjennomføring av lederør eller stigerør, til anvendelse i bunnen av skaf- i tene (1) på en flyttbar, bunnfast offshore plattform ¿ som benyttes under olje- eller gassproduksjon til havs, hvor plattformen består av et betongunderstell ! med en dekkskonstruksjon, og betongunderstellet i består av et eller flere skaft (1) med hylsene (2) ¿ anbragt i bunnen, og hvor hylsen i plattformens | flytefase har dobbel tetning mot sjø, idet hylsens nedre ende er avtagbart tettet (3) ved skaftets underside (S).Tetningen ved hylsens nedre ende før ' første gangs installasjon av plattformen utgjøres i en foretrukken utførelsesform av en skjærplate (3) eller et lokk med et eller flere svekkede partier (3 a), hvilket muliggjør at skjærplaten eller lokket kan slås ut av hylsen ved hjelp av lederøret under lederørets installasjon.Double sealing sleeve (2) for conducting pipe or riser, for use in the bottom of the shafts (1) on a movable, bottom-solid offshore platform ¿used during offshore oil or gas production, where the platform consists of a concrete substructure ! with a deck structure, and the concrete chassis in consists of one or more shafts (1) with the sleeves (2) ¿placed at the bottom, and the sleeve of the platform | The floating phase has a double seal against the sea, the lower end of the sleeve being removably sealed (3) at the underside of the shaft (S). The seal at the lower end of the sleeve prior to the first installation of the platform is constituted in a preferred embodiment of a cutting plate (3) or a lid. with one or more weakened portions (3a), allowing the cutting plate or lid to be knocked out of the sleeve by the guide tube during the guide tube installation.
