Applies broad, in-depth mechanical engineering principles across rotating equipment, piping, pressure systems, HVAC, plant utilities, and balance-of-plant systems.
Independently evaluates complex technical issues and develops robust engineering solutions.
Understands related disciplines (civil, electrical, C&I) to manage interfaces and resolve multi-discipline clashes.
Interprets and applies mechanical codes and standards, including Eurocodes, EN ***********, PED/CE Marking, ASME B31.1/B31.3, and Irish/European regulations.
Maintains up-to-date knowledge of industry practices and mechanical technologies relevant to power-generation EPC projects.
Represents the mechanical discipline in client, vendor, contractor, and regulatory engagements.
Technical Responsibilities:
Lead development, review, and approval of all mechanical engineering deliverables including specifications, datasheets, calculations, P&IDs, 3D model content, and engineering reports.
Oversee mechanical design undertaken by the Engineer of Record (EOR), ensuring alignment with project requirements, Irish/UK regulations, and company standards.
Perform or review calculations for heat balances, pipe sizing & hydraulic analysis, and mechanical integrity and stress checks.
Ensure designs comply with EPC contract requirements, relevant Irish legislation, European standards (PED, ATEX, Machinery Directive), Eurocodes/EN/ISO standards, and utility/grid operator requirements.
Develop and review mechanical specifications for procurement packages (gas/steam turbine systems, pumps, fans, compressors, heat exchangers, boilers/HRSG interfaces, tanks, etc.).
Review mechanical vendor documents, performance curves, general arrangement drawings, stress analyses, welding documentation, NDE requirements, and fabrication/installation procedures.
Lead mechanical engineering risk assessments including design hazard reviews, HAZOP/HAZID participation, constructability reviews, and operability assessments.
Ensure constructability, maintainability, operability, and lifecycle considerations are incorporated into designs.
Contribute mechanical content to plant-wide 3D models and coordinate with piping, structural, electrical, and C&I teams to resolve interferences and optimise layouts.
Support development and maintenance of internal mechanical design standards, templates, procedures, and lessons learned.
Maintain accurate digital records of engineering work in accordance with document control procedures and ISO **** quality requirements.
Program, Project, and Task Management:
Plan, coordinate, and manage mechanical engineering scopes, budgets, schedules, and deliverables.
Develop mechanical inputs for engineering execution plans (EEPs), project schedules, and multi-discipline resource plans.
Support proposal and tendering activities, including equipment lists, mechanical quantities, layout concepts, and performance modelling.
Review mechanical risks, opportunities, and mitigation actions as part of project risk management processes.
Prepare technical content for procurement packages, including mechanical datasheets, scope of supply documents, inspection/testing requirements, and performance guarantees.
Coordinate mechanical interfaces across disciplines (civil, structural, electrical, C&I, process, and construction).
Monitor EOR progress, ensuring timely delivery of mechanical drawings, specifications, and calculations according to project milestones.
Provide technical guidance and coaching to junior and intermediate mechanical engineers.
Support competency and training plans for mechanical engineering staff, aligned with Engineers Ireland requirements.
Review and check the work of team members for compliance with standards, quality procedures, and best practice.
Represent the discipline in coordination meetings and support Project Engineering Manager with reporting and issue resolution.
Lead portions of design reviews, technical workshops, and engineering coordination meetings.
Provide mechanical engineering support to site teams during construction, installation, testing, and commissioning.
Attend site visits to inspect installation quality, mechanical alignment, pipework routing, supports, and equipment placement.
Review and approve method statements, lifting plans, pressure test packages, mechanical completion dossiers, and commissioning procedures.
Resolve mechanical design issues arising during installation and commissioning to protect schedule and cost outcomes.
Support pre-commissioning, energisation, mechanical run-in, performance testing, and final acceptance activities.
Participate in HAZOP closeout, punch listing, NCR resolution, and redline/as-built processes.
Procurement & Subcontractor Interface:
Support procurement in evaluating mechanical equipment vendors and subcontractors.
Review technical bid evaluations and vendor clarifications.
Participate in FATs, design reviews, and vendor meetings.
Lead technical negotiations with suppliers where required.
Support generation of conforming specifications and mechanical sections of purchase orders and subcontracts.
Monitor vendor documentation to ensure compliance with project requirements and timely delivery.
Health, Safety, Environmental & Quality (HSEQ):
