Abstract
A subsea production system adapted for wireless communication so that production tree operation can be controlled locally wirelessly from a workover umbilical or remotely controlled vehicle. The production system includes a wellhead assembly and an umbilical termination connected to an umbilical that extends to above the sea surface. Dedicated wireless communication devices can be attached to one or both of the wellhead assembly and the umbilical termination. The wireless communication devices can include a radio frequency modem, a sonar device, an infrared communication device, a light emitting diode, an optical modem, and combinations thereof; the wireless communication can include radio frequency waves, acoustic waves, and electromagnetic waves. A subsea control module can be included for controlling/actuating devices in or associated with the production system. The subsea control module can be adapted for wireless communication.
