Obtaining data from an underwater component

摘要

A method is described of obtaining data from a subsea control module (1) of an underwater well facility. The method comprises the steps of: providing a tag (2) which stores data relating to the module, the tag being operable to wirelessly transmit the data to a reader device; locating the tag at the module; providing a reader device (4); and interrogating the tag using the reader device, such that the tag is caused to wirelessly transmit the data to the reader device, wherein the tag is communicatively connected to a subsea electronics module for receiving information therefrom.
