Abstract
A technique facilitates deployment and use of a seal rotating system without retrieving the running tool prior to a drilling operation. The running tool remains with the drill string after deployment of the seal rotating system which saves substantial time by avoiding retrieval of the running tool prior to conducting the drilling operation. According to an embodiment, a seal rotating system is mounted to the running tool and the running tool is connected into a drill string. The running tool is used to position the seal rotating system in a rotating control device housing which may be positioned along, for example, a riser. The running tool is then released from the seal rotating system and is moved downhole as part of the drill string to enable performance of a borehole drilling operation without removing the running tool.
