Mechanical Commissioning Engineer – Rotating Equipment
Seeking an experienced Mechanical Commissioning Engineer to commission turbines, generators, compressors, pumps, gearboxes, motors and auxiliary systems on major industrial plants. The role requires strong mechanical engineering and field-execution expertise across installation verification, preservation, alignment, lubrication and sealing, first rotation, dynamic testing, controls and protection interfaces, start-up, performance testing and handover.
Work closely with Engineering, Construction, Electrical, Instrumentation and Controls, Completions, HSE, Quality, subcontractors, OEMs and Operations to deliver safe commissioning and reliable, fully documented handover.
KEY RESPONSIBILITIES
Rotating Equipment Commissioning • Lead commissioning and start-up of turbines, generators, centrifugal, reciprocating and screw compressors, pumps, motors, gearboxes, fans and packaged auxiliaries. • Verify installation, foundations, hold-downs, soft foot, shaft/coupling alignment, piping strain, lubrication, seals, cooling, guards, preservation and reinstatement against approved drawings, vendor manuals and specifications. • Plan and conduct oil flushing, cleanliness checks, leak/pressure testing, bump/rotation checks, solo/uncoupled runs, first rotation, no-load/loaded testing, trip/interlock proving, vibration monitoring, performance testing and acceptance.
Engineering and Design • Review data sheets, P&IDs, layouts, vendor drawings, cause-and-effect charts, control narratives and operating procedures for commissioning, operability, maintainability and safe access. • Resolve design, installation, alignment, lubrication, sealing, vibration, controls and protection issues with Engineering, OEMs and other disciplines during mechanical completion, commissioning and start-up.
Planning, Scheduling and Completions • Develop commissioning plans, procedures, job cards, system/subsystem boundaries, resource requirements, schedules, daily priorities and look-ahead plans. • Use electronic completions systems for walkdowns, mechanical-completion verification, punch management, inspection/test records, handover certificates and turnover from Construction to Commissioning and Operations.
Preservation and Equipment Management • Oversee receipt, storage and preservation, protecting equipment against corrosion, contamination, moisture ingress, brinelling and deterioration. • Confirm preservation release, lubricant condition, temporary-system removal, spares, special tools and vendor documentation before start-up and handover.
Supervision, Contractors and Operations • Supervise and mentor engineers, technicians and work parties; assign tasks by competence and authorisation, monitor execution, deliver practical training and maintain disciplined shift handovers. • Coordinate subcontractors, OEMs, specialist vendors, Construction and Operations on work fronts, permits, method statements, resources, defects, repeat testing, training, spares and handover.
Reporting and Documentation • Report daily/weekly progress, constraints, recovery actions and technical queries. Maintain procedures, check sheets, test results, vibration trends, alignment/flushing records, punch lists and vendor activity records. • Compile traceable turnover dossiers with signed inspection/test records, certificates, redlines, concessions, performance reports, Operations training records and final acceptance documentation.
HSE, Quality and Compliance • Ensure compliance with project HSE requirements, permits, risk assessments, lock-out/tag-out, mechanical isolation, stored-energy controls, approved procedures, OEM limits, quality requirements and applicable legislation/standards. • Lead or participate in toolbox talks, task risk assessments and pre-start reviews. Verify exclusion zones, lifting arrangements, temporary systems and emergency controls; exercise stop-work authority and escalate unresolved technical or safety risks.
QUALIFICATIONS
Education Bachelor’s degree in Mechanical Engineering or a related field, HNC/HND, recognised mechanical craft apprenticeship, or equivalent technical qualification supported by substantial relevant field experience.
Experience • 10+ years’ mechanical commissioning experience on major oil and gas, power, petrochemical, process, steel or comparable industrial projects, with substantial recent rotating-equipment field responsibility. • Proven hands-on installation and commissioning of multiple complex turbine, generator and compressor packages, including alignment, lubrication/seals, first rotation, dynamic testing, controls/protection interfaces and acceptance testing. • Experience supervising personnel, coordinating subcontractors/OEMs, working with Operations, mentoring/training teams and using electronic completions systems.
Skills and Expertise • Strong knowledge of rotating-equipment installation, preservation, alignment, lubrication, sealing, vibration, condition monitoring, troubleshooting, performance testing and applicable API, ISO and project standards. • Ability to interpret P&IDs, data sheets, isometrics, vendor manuals, cause-and-effect charts and control narratives, and prepare safe commissioning procedures and test records. • Excellent communication, field leadership and problem-solving skills; effective under schedule pressure, with clear communication of technical risks and priorities. • Collaborative approach across disciplines, contractors, vendors and Operations, maintaining high HSE, quality and equipment-integrity standards.
PREFERRED QUALIFICATIONS • OEM/field-service training on turbine, compressor or generator packages, plus recognised alignment, vibration, lubrication, isolation-authority or mechanical commissioning certification. • Experience with Siemens, Rolls-Royce, MAN, Howden, Voith or comparable suppliers, and high-hazard continuous-process, power-generation, oil and gas, green-steel or similar facilities.
ADDITIONAL INFORMATION Site-based role in an active construction and commissioning environment in Boden, Sweden. Shift work, extended hours and travel may be required to meet the project schedule. Candidates must be medically fit, hold required site-access credentials, be fluent in written/spoken English and demonstrate strong leadership, mentoring, contractor-management and Operations-interface capability.
