Abstract
Den foreliggende oppfinnelse vedrører utstyr installert i en mellomregion mellom en flytende produksjonsenhet ved sjøoverflaten og brønnhodet til et oljereservoar på sjøbunnen. Utstyret, kjent som en underoverflatebøye, er konstruert for å understøtte stive og fleksible produksjonsrør benyttet for transport av reservoarfluider fra oljebrønnen og/eller fluider benyttet i støttesystemer for oljereservoaret. Fire sylindriske legemer (1), (2), (3) og (4), sammenkoplet i sine ytterender, danner legemet til underoverflatebøyen. I hver av vertikalitetene til underoverflatebøyen er komponenter til et fortøyings- og dynamisk stabiliseringssystem (13) stivt forbundet. Dette fortøyings- og dynamiske stabiliseringssystemet (13) er konfigurert for å regulere posisjoneringen av underoverflatebøyen, trekket til installasjonskjettinger (15) og forankringstau (21), og dermed fremme en stabilisering av hele sammenstillingen mot storamplituderotasjoner eller vinkelendringer, selv etter at stive rør (10) og fleksible rør (11) er koplet til legemet til underoverflatebøyen. I tillegg er det også fremlagt en fremgangsmåte for å installere underoverflatebøyen.The present invention relates to equipment installed in an intermediate region between a floating production unit at the sea surface and the wellhead of an oil reservoir on the seabed. The equipment, known as a sub-surface buoy, is designed to support rigid and flexible production tubes used for transporting reservoir fluids from the oil well and / or fluids used in oil reservoir support systems. Four cylindrical bodies (1), (2), (3) and (4), interconnected at their outer ends, form the body of the sub-surface buoy. In each of the verticals of the sub-surface buoy, components of a mooring and dynamic stabilization system (13) are rigidly connected. This mooring and dynamic stabilization system (13) is configured to control the positioning of the sub-surface buoy, the tension of installation chains (15) and anchoring rope (21), thus promoting stabilization of the entire assembly against large amplitude rotations or angular changes, even after rigid tubes (10). ) and flexible tubes (11) are connected to the body of the sub-surface buoy. In addition, a method of installing the sub-surface buoy is also provided.
