Procedures for pre-commissioning pipeline


Customer: Nord StreamVTT pipeline materials corrosion


Ecological compatibility of the used methods, and corrosion caused by microbiological activity to pipeline materials due to natural seawater used as pre-commissioning water.

  • Providing empiric data to support decisions and offer suitable methods to prevent corrosionVTT graph
  • Defining the likelihood of seawater corrosion and verification the most environmental friendly water treatment method for pre-com-missioning without endangering the integrity of the pipeline.
  • Eefficient simulation of pre-commissioning process, monitoring corrosion and biofilm formation with sophisticated electrochemical and molecular biological methods.

Results of pre-commissioning studies will help to

  • reduce costs
  • increase lifetime and safety of the pipeline
  • decrease the deposit forming.
