Abstract: An in-riser communication system includes a riser extending from a surface facility to a subsea wellhead, a communication tool installed on a tool string, wherein the tool string is disposed in the riser, a repeater positioned on an exterior of the riser, a remote operated vehicle (ROV), and a computer system operatively connected to the ROV. When the communication tool and the repeater are positioned in proximity to one another, data is transferred from the communication tool, to the repeater, then to the ROV, and then to the computer system for processing.
