Abstract

Et system for kommunikasjon mellom et overflateutstyr og et undervanns produksjonskontrollsystem, som innbefatter en kommunikasjonsenhet nær vannoverflaten. Denne enhet nær vannoverflaten har minst ett kommunikasjonsgrensesnitt. En kommunikasjonsenhet er funksjonsmessig tilordnet et brønnhode eller en undervannskonstruksjon. Kommunikasjonsenheten nær sjøbunnen har minst ett kommunikasjonsgrensesnitt. En kommunikasjonskanal strekker seg mellom kommunikasjonsenheten på overflaten og kommunikasjonsenheten nær sjøbunnen. En multiplekser er funksjonsmessig koplet til kommunikasjonsgrensesnittet for hver av enhetene, nemlig enheten på overflaten og enheten ved sjøbunnen. Minst to avstandsanordnede enheter er funksjonsmessig koplet til sjøbunnmultiplekseren. De avstandsanordnede enheter omfatter minst én av: en sensor og en kontroll. Minst to tilsvarende enheter er koplet til overflatemultiplekseren. De to tilsvarende enheter omfatter minst én av: en signalinnsamlingsenhet og en enhet for generering av kontrollsignaler.
