Flow Systems

Offshore Flow Surveys

Pipelines require testing, purging and cleaning, at the pre-commissioning stage and before a product change. Our flow meter engineers are able to visit your offshore facilities to offer offshore flow surveys for applications that include:

  • Pipeline dewatering
  • Vacuum drying
  • Pipeline purging


BOSIET, OG UK and MIST Accredited Flow Meter Engineers

Our fully trained engineers understand the importance of pipeline cleaning and purging to ensure efficient and effective operations. Through accurate flow measurement they are able to gauge the success of each stage of the pipeline preparation process.

They are fully accredited to work offshore, including BOSIET trained and both OG UK and MIST medical certificates.


Expert and Experienced in Offshore Flow Survey Applications

A pipeline must be capable of containing product without leaking and it has to be clean before it is put into service, so testing and dewatering is an essential part of the pipeline commissioning process. It involves pushing a pig through the pipeline propelled by a gas to remove the test water prior to start-up.

Vacuum drying intensifies the evaporation of water and the boiling point of water drops with decreasing atmospheric pressure. This is an effective method of drying a pipeline to prevent internal corrosion and the formation of hydrates. Pipeline purging, through the displacement of one gas by another, occurs on a routine basis in the natural gas industry as pipelines are purged into and out of service.

Flowhire are specialists in the offshore industries, so we understand how important it is to help you to make sure that every stage in pipeline preparation has been accomplished and the pipeline is ready for installation. Trust Flowhire to give you the flow survey service you need.
