摘要： There is disclosed a system for monitoring abandoned subsea wells with a Wet Christmas Tree (WCT) comprising a Control Module to be installed on a modified abandonment cap and a Communication Module coupled beneath the ROV to perform the communication with the control system of the Control Module by way of an electric jumper and supply hydraulic power to the control system by way of an hydraulic jumper. The system is useful for wells with a VCM or three VCMs. In this case, the modified abandonment caps are used. The monitoring method of the abandoned subsea wells with WCT is also described.
