S2F Global is seeking a Senior Commissioning and Start-Up (CSU) Operator to bring a sour gas plant online.

The Operator's first priority is to assist and advise with the plant start-up and apply special attention in getting the SRU running reliably. Beyond the hands-on operation, they will act as the site's sulphur plant subject matter expert during start-up. The operator will be required to assist with start up in all areas.

• Operate the waste heat boiler and steam system through start-up and load changes, in line with ABSA requirements.

• Tune air-to-acid-gas ratio and tail gas performance to meet sulphur recovery and emissions targets.

Commissioning and Pre-Start-up

• Assist and advise with any Pre-Start-up Safety Review (PSSR) as directed by the client.

• Assist with any start-up, operating, shutdown, and emergency procedures as directed by the client.

• Assist and advise as required in all process units as directed by or requested by the client.

Safety, Training, and Handover

• Mentor and train site operators on sulphur plant and amine operation if required.

• Investigate and follow up on start-up incidents and near misses if required.

• Complete handover notes of any findings and or improvements for the permanent operations team.

• 20+ years of operations experience in sour gas processing plants.

• 10+ years of hands-on operation of multi-stage Claus sulphur plants, with direct Super Claus tail gas experience.

• At least two full commissioning and start-ups of a sulphur recovery complex, ideally including a greenfield start-up.

• Strong amine or Sulphinol sweetening experience, including sour water stripping.

• Experience running a plant as operator in charge or panel operator during start-up.

• Proven troubleshooting of SRU mechanical and process problems, including waste heat boilers and steam systems.

• Experience writing operating and start-up procedures and supporting PSSRs.

• Deep-cut or refrigeration experience with deethanizer, depropanizer, and debutanizer columns, is an asset.

• Field, inlet, and sales compression and condensate stabilization experience, is an asset.

• Turnaround coordination or major shutdown and start-up planning, is an asset.

• Experience training operators or supervising a sulphur plant crew, is an asset.

• Background at large Alberta sour gas complexes or upgrader sulphur units, is an asset.

• 2nd Class Power Engineering certificate (ABSA) minimum; 1st Class strongly preferred.

• H2S Alive.

• Standard First Aid and CPR.

• Valid driver's licence and reliable transportation to site.

Schedule and Working Conditions

This is an intensive start-up assignment, so expect long, near-continuous shifts until the plant reaches stable operation.

• Extended hours and on-call availability during commissioning.

• Work in a sour gas environment with H2S exposure risk and full PPE requirements.

• Outdoor work in northern Alberta weather conditions.
