Abstract

Det omtales et system for å beskytte rørledninger nedstrøms til et brønnhode, som omfatter et innløp koplet til brønnhodet og et utløp koplet til nedstrømsrørledningen. To sett av seriekoplede overflatesikkerhetsventiler er i et parallelt fluidstrømnings-5 forhold til hverandre, og i fluidkommunikasjon med innløpet. To luftekontrollventiler, som er i fluidkommunikasjon med hverandre, hver av de to seriekoplede sikkerhetsventilene og innløpet og utløpet til systemet, er mellomliggende koplet til sikkerhetsventilene. Hver luftekontrollventil er i fluidkommunikasjon med en lufteledning for lufting av prosesstrykk mellom overflatesikkerhetsventilene gjennom utløpskontroll-10 ventilen basert på en signalgenererende sikkerhetslogikkinnretning som har forhåndsprogrammert sikkerhet og operative protokoller og trykkregistrerende sendere tilkoplet oppstrøms til utløpskontrollventilen. Uavhengige, tette avstengningstester til hvert seriekoplede overflatesikkerhetsventilsett lukker alle ventiler ved elektriske eller hydrauliske feil.
