USER NEEDS

Provision of the on-line information on the current and expected geomagnetic conditions

benefits the planning and performance of corrosion protection surveys.

On-line modelling of PSP at the pipeline test posts during corrosion protection surveys helps in interpretation of field PSP data

On-line information on the time and location of PSP out of safe range

contributes to the proper evaluation of pipeline performance and expected lifetime.
