Summary
Learnings
Documents

The objectives of this Project are set out below: 

  • Investigation of flame arrestor development, (IGE/SR/22 requires flame arrestors to be used on vents that flow less than 10 m/s.) Investigations should be made to see if these need sourcing for hydrogen and if so, identifying where and how this can be done.
  • Calculation of purge tables and purge calculators for hydrogen use as specified in ML2 and other SGN procedures.
  • A purge vent design that is clearly different to a natural gas vent that can be used for hydrogen. The vent is not expected to include a flame arrestor but instead produce a flow speed sufficient to prevent burn back during a purge.
  • Mitigating unwanted ignition mechanisms including non-sparking hand tools – review non-sparking tools used in the offshore environment and provide recommendations for H100
Benefits

The project will provide learning on the following topics:
