* Support COMAH requirements, including MAPP/Safety Report input, escalation prevention and emergency exercises.
* Maintain compliance with PUWER and LOLER for all work equipment, cranes and lifting accessories.
* Drive statutory inspection readiness, including documentation, remediation and Competent Authority engagement.
* Improve reliability through RCM, RBI, FMEA, defect elimination and KPI trend analysis (MTBF, OEE, backlog).
* Set predictive and preventive maintenance strategies, shutdown scopes, lubrication and overhaul regimes.
* Lead MOC processes ensuring risks (DSEAR/COMAH/CDM) are assessed and controlled before implementation.
* Review and deliver mechanical design: calculations, specifications, datasheets and vendor supply packages.
* Support construction and CDM compliance including temporary works, lifting and mechanical completion.
* Provide operational troubleshooting, startup/shutdown support and continuous improvement input.
* Prepare asset investment plans, maintenance budgets and long‑term capex/opex forecasts.
* Grow team capability through procedures, SOPs, toolbox talks and mentoring.
Knowledge & technical know-how

* Pressure systems legislation and practice: PSSR 2000 incl. WSE/Competent Person interfaces.
* CDM 2015 role clarity (client/principal designer/principal contractor).
Skills and experience required
* RCM/RBI/FMEA facilitation and root cause analysis (RCA).
* Mechanical design review competency (pressure parts, rotating equipment, materials, codes).
* MOC leadership and stakeholder communication.
* CMMS/EAMS configuration for mechanical assets and reliability KPI analytics.
* Minimum of 3 years in petrochemical, gas, power, or hydrogen projects/operations with rotating/static equipment.
* Demonstrable track record establishing maintenance strategies and achieving reliability improvements.
Qualifications
* Degree (BEng/BSc) in Mechanical Engineering (or closely related).
* Working towards or already Chartered Engineer (CEng) with IMechE (or equivalent).
* Desirable: Company appointment as AE/AP (Mechanical/Pressure Systems), NEBOSH Process Safety, ISO 55001 asset management training, Six Sigma/Lean, CDM duty holder awareness.
