Subsea control and communication system

Abstract

A subsea control system for transmitting and receiving subsea related data to and from a surface control system includes a connecting Subsea Electronic Module (SEM) 208 in connection with a high-speed communications conduit. The connecting SEM receives and transmits the subsea related data to and from the surface control system via the high-speed communications conduit. A plurality of processing SEMs 210 for which each is connected to the connecting SEM to receive and transmit the subsea related data. A portion of the connection between each processing SEM and the connecting SEM includes a high-speed connection, wherein the receiving and transmitting of subsea related data between the connecting SEM and the processing SEMs on the high-speed connection is in compliance with the IEEE 802.3cg standard as of the 27th of July 2023.
