Abstract
Det er beskrevet en fremgangsmåte for å kontrollere fenomenet med voldsom støtvis strømning l undersjøiske ledninger ved flerfasestrøm, så som de som overfører petroleum fra et undersjøisk brønnhode til overflaten, Innbefattende Installa- sjon av minst en sekundær ledning (3), en sekundær stigeled- ning som starter ved produksjonslednlngen (1) med nedover- vendt geometri og slutter l den vertikale ledningen (2) som overfører fluider til produksjonsenheten, hvilken sekundær ledning (3) oppsamler gass som utskilles ved toppen av produksjonslednlngen (1) ved nedovervendt geometri ved et punkt B anordnet l en avstand "L" fra forbindelsen C mellom produksjonslednlngen (1) og den vertikale ledningen (2) og transporterer gassen til et punkt A, anordnet l den vertikale ledningen (2) og en avstand "H" fra nevnte forbindelse C, hvor trykkdlfferenslalet mellom punktene A og B sikrer gasstrøm mellom disse punktene med muligheter for å Installe- re en kontrollventll (4) l den sekundære ytterligere ledningen (3) for å kontrollere gasstrømmen, hvor driften av kontrollventllen reguleres med en primær kontrollanordnlng (15) som måler noen fysiske størrelser som er betydelig for kontroll av den voldsomme støtvise strømningen, så som trykk eller tetthet, og som virker på kontrollventilen for å sikre en stabil gasstrøm.
