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.A system for communication between a surface equipment and an underwater production control system, which includes a communication unit near the water surface. This unit near the water surface has at least one communication interface. A communication unit is functionally assigned to a wellhead or an underwater structure. The communication unit near the seabed has at least one communication interface. A communication channel extends between the communication unit on the surface and the communication unit near the seabed. A multiplexer is functionally connected to the communication interface for each of the units, namely the unit on the surface and the unit at the seabed. At least two spacer units are operatively connected to the seabed multiplexer. The spacer units comprise at least one of: a sensor and a control. At least two corresponding devices are connected to the surface multiplexer. The two corresponding units comprise at least one of: a signal acquisition unit and a control signal generation unit.
