Abstract: A method of installing a subsea cable bundle including an umbilical and at least one direct current and fibre optic (DCFO) cable attached to an outside of the umbilical includes connecting a first end of the cable bundle to a pulling head, lowering the first end of the cable bundle into the se, connecting the pulling head to a winch cable of a winch (the winch may be connected before or after lowering the first end), the winch being located on a platform and the winch cable extending from the platform into the sea through a J-tube, and using the winch to pull the first end of the cable bundle up to the platform through the J-tube. The method further includes laying the cable bundle on the seafloor, and at a target location, at or close to a subsea structure, detaching the DFCO cable from the umbilical and connecting the DCFO cable and the umbilical at their second ends to the subsea structure.

Abstract: A subsea umbilical laying method includes mechanically coupling an umbilical termination assembly at an end of a first umbilical to an umbilical termination assembly at an end of a second umbilical, and subsequently deploying the mechanically coupled ends of the first and second umbilicals together in a subsea umbilical laying process.

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.
