Abstract
This invention concerns a multiplexed electrohydraulic kind of control system consisting of ten undersea control modules, (24), arranged and installed one for each local Xmas tree (14) and satellite Xmas module (18). System links up with a stationary production system by two hydraulic umbilicals, (42), and one electric umbilical, (44), this latter through an electric distribution module, (26), while connection of jumper, (84) of undersea control module, (24), and to electric distribution module, (26) is done by a remotely controlled vehicle (R.O.V.), (30).
