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.

In-riser tool operation monitored and verified through ROV

A running tool () having an annulus seal assembly () and casing hanger () attached thereto may be sent into to the wellhead () to lock and preload the casing hanger () in a single trip. The running tool () may be rotated a first time to drop the annulus seal assembly on the casing hanger (), a first pressure may be applied axially above the annulus seal assembly to set the annulus seal assembly, the running tool may be rotated a second time to close a gap between the annulus seal assembly and the wellhead, and a second pressure may be applied axially above the annulus seal assembly to preload the casing hanger.
