Abstract
A system for tagging and monitoring subsea installations such as valves used in hydrocarbon production includes a torque tool provided with a read/write head for inductive interaction with a data storage capsule on a valve installation, the capsule storing valve identification and status data. When the torque tool is operatively engaged with the shaft (or an adaptor) of the valve, the read/write head inductively energizes the capsule and inductively receives identification data from the capsule, as well as operating data of previous operation, and this data is sent to a console in an ROV so as to ensure correct identification of the valve and proper subsequent operation by the tool.
