Abstract
A subsea oil and/or gas production system comprises a host production facility and a plurality of subsea wells. A fluid conveying network is provided that connects each subsea well to the host production facility. A separate electrical power and data network is provided for conveying direct current electrical power and data, operatively connected to each subsea well for providing each subsea well with data transfer and electrical power services. The use of direct current ensures that the electrical power and data network can provide power over much greater distances than currently available, and the use of separate networks for conveying fluids and for providing electrical power and data transfer allows for a much more flexible system.
Claims11
A subsea oil and/or gas production system comprising:
- a host production facility;
- a plurality of subsea wells;
- a fluid conveying network connecting each subsea well to the host production facility;
- and
- an electrical power and data network for conveying direct current electrical power and data, operatively connecting the host production facility to each subsea well for providing each subsea well with data transfer and direct current electrical power services, the direct current electrical power and data network being separate from the fluid conveying network and conveying no fluid.
A subsea hydrocarbon production system comprising:
- a host production facility, the host production facility linked to a first fluid conveying network connecting at least one subsea well to the production host facility, and a second fluid conveying network connecting at least one further subsea well to the host production facility;
- a subsea electrical power and data network for conveying direct current electrical power and data, the electrical power and data network conveying no fluids and comprising a hub, wherein the network connects the hub to the host production facility and to the subsea wells, wherein the first and second fluid conveying networks are separate from the subsea electrical power and data network.
