Subsea oil pipelines reheating system (France)

Qualification tests for a prototype

Client: Technip FMC - Scale: 1/1

Context

TECHNIP FMC started the development of a prototype which is a heating system electrically powered, aiming at removing hydrate plugs in subsea oil pipelines. This prototype was subjected to a qualification test as part of its development process. The qualification comprised execution of different operational scenarios in conjunction with the the pipeline, where the prototype performance was checked by means of various sensors and a further analysis of logged data carried out by TECHNIP FMC.

ARTELIA was awarded the execution of the qualification tests which occured in its Hydraulics Laboratory.

Lab activities

  • Test bench preparation, including mobilization of the basin, heated water supply and circulation system, setting up of the various components: prototype, pipelines, sand material (reproducing a sandy seabed), boiler and sensors
  • Development by the ARTELIA instrumentation team of a dedicated software to record and transfer the measured data
  • Tests execution
