Abstract: The present invention relates to an electrical power transmission system (100) which utilizes HVDC technology to supply power over long distance to an underwater system (130) such as a modular seabed processing system (300). The system (100) comprises a host station (110), a remote power conversion facility (120) and an Integrated Service Umbilical (150) which is connected to the underwater system (130). The host station (110) transmits DC power through a submarine power cable (140) to the remote power conversion facility (120) which is more than 100 km from the host station (110). Thereon, the remote power conversion facility (120) which includes a DC to AC inverter (123), a transformer (122) and a local control station (121), converts the DC power to the required AC power for the underwater system (130). The operation of the transmission of power to the underwater system (130) is monitored and controlled through a master local control station (111) at the host station (110) and/or a local control station (121) on the remote power conversion facility (120). Advantageously, electrical power may be supplied to an underwater system (130) which is more than 100 km from a power source. In addition, the underwater system (130) and the power transmitted can be remotely monitored and controlled.

Abstract: A control system of modular seabed processing unit (100) using one of a process module as a test separator comprising a system-module (110) to which external lines are connected, the system-module (110) includes a first portion (31) of the system-module isolating and connecting means (30), for acting on received fluid. At least one inlet flow line (21) and at least one outlet flow line (81) being connected to the first portion (31) of the system-module isolating and connecting means (30) for selective isolation of system-module from, or connection of the system-module to the external flow lines by means of a second complementary portion (32) of a manifold (130). The system-module includes control means (60) for controlling operation of the system-module characterized in that the system-module (110) includes at least one actuating means (121) connected to a control means (60) wherein the actuating means (121) of the system-module (110) associated with diverter valve (131) situated at a manifold (130). The diverter valve (131) is connectable and disconnectable to fluid carrying conduits from production well (160, 170) and is enabled to control the direction of fluid flow into the system-module.
