摘要：
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.
