Siemens Energy

A Snapshot of Your Day

• Carry out gas handling, gas operations, leak detection, gas filling, gas recovery, gas quality analysis and system integrity checks on high voltage substations, gas insulated switchgear, and associated assets.
• Operate approved gas management equipment (e.g. DILO devices referenced by project teams).
• Display competence and confidence working with pressurised systems and making pressurised equipment safe to work on.
• Support installation and commissioning teams with gas-related tasks as required.
• Perform diagnostics, troubleshooting, and remedial activities in line with engineering guidance.
• Use appropriate technical drawings as required. Highlight and report possible errors within drawings to site supervisors, site managers or design engineers.
• Interpret test and inspection reports associated with the role and initiate appropriate action.
• Complete and maintain gas processing logs, service reports, check sheets, and operational documentation.
• Ensure all gas operations follow Siemens Energy standards, method statements, and safe systems of work.
• Ensure risk assessments and method statements are completed appropriately.
• Maintain, safeguard and calibrate where necessary all tools and equipment associated with the role.
• Adhere to Zero Harm principles, permit-to-work systems, and site-specific safety rules.
• Ensure correct use of PPE, gas monitoring devices, and safety controls at all times.
• Ensure Siemens Energy environmental policies are adhered to.
• Ensure work will be carried out in such a way to prevent or minimise harmful impact to the environment.
• Support supervisors, engineers, and gas insulated switchgear specialists when cross-functional support is required.
• Provide feedback to improve work practices, documentation, and training pathways.
• Support less experienced colleagues, including apprentices where applicable.
• Report to site supervision, site management or project management regarding the progress and status of the tasks taking place.
• Report to site supervision, site management or project management regarding any problems or issues which could affect the delivery of the tasks being carried out.
• Plan day to day work for themselves and their working party.

• The Gas Technician supports the delivery of insulating gas-related high voltage installation, commissioning, maintenance, decommissioning and operational activities across Siemens Energy projects in the UK.
• The Gas Tech ensures all work is performed safely, efficiently, and in compliance with internal standards, policies and permit scheme requirements in addition to customer safety rules & specifications.
• The Gas Tech plays a key role in field execution and functional safety, contributing directly to Zero Harm, quality assurance, environmental safeguarding and on-time project delivery.
• Establish, maintain and work according to internal work permit schemes or equivalent principal contractor/client safety rules. Gain and maintain authorisations and certification proving competency prior to undertaking gas work.
• Contribute to investigations or corrective actions where gas-handling issues arise.
• Display confidence and competence in controlling work on pressurised equipment including issuing Siemens Energy’s pressurised system permits to work and receiving permits whether Siemens Energy’s internal permits or permits under client safety rules.
