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.

Each module has a control pod which is able to control flows of fluids between the subsea developments and between the subsea developments and the receiving facilities, and each control pod is connected to monitoring devices for monitoring parameters pertaining to the subsea developments. Parameters are monitored at a first one of the subsea developments and a requirement for a first fluid type is identified and parameters at another second one of the subsea developments are monitored and a surplus of the first fluid type is identified. The relevant control pods are then operated to enable a quantity of the first fluid to be conveyed from the second to the first subsea development via the pipeline network (94).

Abstract: A system for separating fluids from a hydrocarbon well production fluid mixture at a subsea location has a centrifugal separator (16) for separating the mixture into gas and liquid. A hydrocyclone separator (32) then separates the liquid into oil and water and an oil-in-water sensor (38) detects the amount of oil in water leaving the separator. If the sensor (38) detects that the water contains more than the prescribed amount of oil, the water is recirculated through the hydrocarbon separator (32) for removal of further oil form water. The hydrocyclone separator (32) has a level interface sensor (66) and if this sensor detects that the oil/water interface is not within prescribed limits for optimum separation of the oil and water, the amount of oil removed from the separator is adjusted until the oil/water interface is within the prescribed limits. The sensors (38, 66) are connected to a control means (68) which controls electrically actuable control valves (42, 58) to cause the water to be recirculated to adjust the amount of oil removed from the hydrocarbon separator. The system also includes a gas slug detection device (14) upstream of the centrifugal separator (16) for sensing the presence of a gas slug in the production fluid. A liquid flow control valve (21) is adjusted by the control means (68) to ensure that the level of liquid in the centrifugal separator (16) does not fall below prescribed limits.

Abstract: Method and apparatus for assisting the flow of production fluid from a hydrocarbon well to a remote location in conditions in which gelling or solidification is a problem. The method involves adding dilution fluid (60) such as water, to production fluid from a wellhead (4) in a first sub-system (8) close to the wellhead (4), conveying the mixture to a second sub-system (14) where the dilution fluid (60) is separated from the mixture in a separator chamber (38) as a consequence of their different specific gravities, recirculating the separated dilution fluid back to the first sub-system (8) and adding it to further production fluid from the wellhead (4). The requirements for pipeline heating, chemical injection and conveying large volumes of dilution fluid to a host facility can be avoided by the invention.
