Abstract (en)
A system for tagging and monitoring subsea installations such as valves used in hydrocarbon production includes a torque tool (10) provided with a read/write head (18) for inductive interaction with a capsule (16) on a valve installation (12), the capsule (16) storing valve identification and status data. When the torque tool (10) is operatively engaged with the shaft (or an adaptor) of the valve, the read/write head (18) inductively energizes the capsule (16) and inductively receives identification data from the capsule (16), as well as operating data of previous operation, and this data is sent to a console (26) in an ROV so as to ensure correct identification of the valve and proper subsequent operation by the tool (10). <IMAGE>
