Abstract (en)
[origin: EP2469015A1] A method for generating a time-dependent profile of a parameter, the parameter being associated with the operation of a device at an underwater well facility, comprises the steps of: i) obtaining data relating to measured values of said parameter, ii) passing said data to a storage means, iii) storing said data to produce a set of data related to the parameter at a plurality of times, and iv) generating a profile of the parameter from the data set.
