Home-based
Permanent position

The Role:
As a Senior Structural & Mechanical Integrity Engineer within the Asset Integrity Management (AIM) team, you will act as the technical authority for the structural and mechanical integrity of offshore transmission and renewable energy assets operated and maintained by James Fisher Renewables.

The role provides lifecycle engineering assurance across offshore substations, foundations, primary and secondary steelwork, mechanical systems, corrosion protection, lifting equipment, and subsea interfaces. You will define integrity strategies, assure inspection and assessment activities, evaluate degradation and fatigue mechanisms, and lead risk-based decisions that protect safety, availability, and OFTO revenue.

Key skills, knowledge and experience:
Global/regional function:
The role currently covers engineering support to Europe and APAC, with future expected coverage of USA and AUS.
Remote with travel to JFR Offices and HV Control Centre (Belfast) - as required.
Occasional requirement for visits to offshore substations, onshore substations, and vendor facilities across the UK as dictated by the project requirements.

• Technical authority for structural and mechanical integrity matters
• Approval of inspection strategies, assessment methodologies, and remediation recommendations
• Authority to define integrity risk rankings and intervention priorities
• Engineering sign-off support to Asset Managers and Operations teams

Structural Integrity Management:
Assess the condition of offshore structures including primary and secondary steel, decks, gratings, handrails, ladders, W2W structures, and access systems.
Review foundations, jackets, and monopiles using inspection data, ROV footage, bathymetry, scour surveys, and structural assessments.
Assess J-tubes, bell mouths, clamps, bend restrictors, and cable interface structures.
Review cable protection systems (CPS) and identify exposure, damage mechanisms, and structural vulnerabilities.

Mechanical Systems Integrity:

• Provide integrity oversight for HVAC systems, cranes, davits, mechanical handling systems, fire systems, and auxiliary plant.
• Review mechanical degradation, corrosion mechanisms, coating failures, and fatigue-related defects; define remediation.
• Support compliance with LOLER, PUWER, COSHH, DSEAR,

• Ensure compliance with DNV and ISO standards relevant to offshore structures (e.g., DNVGL ST codes), API RP 2A for fixed platforms where applicable, BS EN standards for cranes and mechanical systems, ISO 9001/14001/45001, ISO 55000 asset management.

Inspection, Assurance & O&M Engineering Support:

• Define and review inspection scopes, work packs, and offshore execution methodologies
• Interpret inspection findings, classify defects, and define remediation strategies with costed options.
• Maintain integrity documentation, inspection records, certificates, and asset registers
• Provide engineering input to outage planning, access strategies, and operational risk reviews

Engineering Assurance & Continuous Improvement:

• Contribute to condition assessments, root cause analyses, and integrity risk evaluations.
• Develop corrosion management strategies and optimise inspection intervals.
• Support structural upgrades, modifications, CPS improvements, offshore engineering consultancy and asset life-extension studies.
• Provide specialist input to offshore wind, interconnector, and marine infrastructure projects.

Interfaces and collaboration:

Work with Operations, Blades, HV Services and Cables and OFTO Operations teams.

Liaise with OEMs, classification societies and specialist contractors.

Authority and decision rights:
Approve inspection strategies, assessment methodologies and remediation recommendations.
Define integrity risk rankings and intervention priorities; provide engineering sign off to Asset Managers.

Who are we looking for?
You will have strong analytical and diagnostic skills, along with strong inspection interpretation and structural/mechanical assessment skills.
Clear reporting and documentation capability and operational awareness of offshore environments.
An analytical and risk-based engineering approach.
Be able to contribute to the digital asset management database, and client reporting on asset health.
Lead by example on life saving rules and safe systems of work and produce or contribute to the production of clear risk assessments, method statements and technical reports for mechanical and structural related tasks.
Review of third-party risk assessments, method statements and technical reports.

Skills and Experience:

• Degree qualified in Structural or Mechanical Engineering.
• Chartered Engineer (CEng) or working towards is preferred.
• Lifting knowledge aligned to LEEA guidance; relevant NDT qualifications desirable.
• Extensive experience with offshore platforms, offshore wind substations, or marine structures.
• Strong understanding of corrosion protection, structural assessment and mechanical systems – including pressurised systems, HVAC, lifting equipment, and rotating machinery.
• Familiarity with FEA and structural modelling tools (e.g., ANSYS, ABAQUS, SESAM) is desirable.
• Experienced in interpreting ROV data, bathymetric surveys, and subsea structural interface inspection datasets.
• Familiarity with offshore standards, integrity management frameworks, and risk-based methodologies.
• GWO certifications and Offshore Medical (or willingness to obtain) for offshore access (if desired)
