A subsea communication system is used to communicate between a position that is proximal to a surface of the sea and an apparatus of the seabed. The subsea communication system includes an umbilicalless communication system.

Subsea communication system and technique

A subsea communications module includes an interface to communicate with a surface facility over a communications link using a packet-based protocol. The communications link can be implemented with a fiber optic line, wire-based line, and/or other types of communications lines.

Subsea communications system

A system that is usable in a subsea well includes a tubular string that extends from a surface platform toward the sea floor. The string has an upper end and a lower remote end that is located closer to the sea floor than to the platform. At least one sensor of the system is located near the remote end of the string to monitor deployment of subsea equipment.

System and technique for monitoring and managing the deployment of subsea equipment

A system that is usable with a well includes a structure that has a region that is adapted to receive a tubing hanger interface. The system also includes at least one communication connection that penetrates the structure below the region to receive the tubing hanger interface.

Power system for a well

A system for use with a subsea well that includes a BOP includes a fluid line and a tool that is not connected to the fluid line. The fluid line is connected to the BOP to communicate a pressure encoding a command, and the tool is adapted to decode and respond to the command when the tool is inside the BOP.
