Maintenance Engineer
As a Maintenance Engineer working in offshore wind farm energy storage, you’ll be responsible for inspecting, repairing, and improving the machinery and infrastructure that store and distribute hydrogen and electricity. In the Storage & Industrial zone, your focus will be on keeping hydrogen tanks, battery storage systems, gas pipelines, and distribution equipment operating safely, efficiently, and without interruption. You’ll be key to avoiding costly downtime and ensuring everything meets safety and environmental standards.
Key Responsibilities
Maintenance Engineers in the Storage & Industrial Zone are responsible for:
• Carrying out routine inspections of hydrogen tanks, pipelines, compressors, and battery systems
• Diagnosing and fixing faults in mechanical and electrical systems
• Performing planned preventative maintenance to avoid breakdowns
• Updating maintenance logs and technical records
• Monitoring system performance to detect early signs of problems
• Working alongside energy engineers to optimise the storage and distribution of renewable energy
• Ensuring all maintenance work meets strict health, safety, and environmental standards.
They help keep the entire offshore storage network running smoothly and efficiently.
What You’ll Most Likely Be Doing:
• Inspecting and testing equipment - Checking pressure gauges, flow meters, valves, and electronic sensors.
• Responding to breakdowns - Quickly diagnosing faults and replacing worn-out parts before they cause bigger issues.
• Carrying out upgrades - Installing new components or system improvements to increase efficiency.
• Following technical blueprints - Reading engineering drawings and manuals to maintain complex machinery.
• Health and safety checks - Making sure that all operations are safe, especially when working with hydrogen systems.

Essential Skills
To be a successful Maintenance Engineer, you’ll need:
• Strong problem-solving abilities.
• Attention to detail and methodical working.
• Good practical hands-on skills with tools and machinery.
• Ability to read technical manuals and engineering diagrams.
• Knowledge of health and safety regulations.
• Good teamwork and communication skills.
• Ability to work independently under pressure.
Qualifications and Training
At school and college, you’ll typically need GCSEs: Minimum 4–5 passes at grade 4/C or above, especially in:
• Mathematics (important for calculations and measurements).
• English (for understanding technical documents).
• Science (especially Physics for understanding systems and forces).
Further education: After GCSEs, you can move into college or go on apprenticeships in engineering maintenance.
After that, you can choose the apprenticeship route by applying for a Maintenance and Operations Engineering Technician apprenticeship. Or the University route, by gathering a wider knowledge of engineering systems before specialising further in maintenance for offshore wind and hydrogen energy storage facilities.
While university isn’t always mandatory, many Maintenance Engineers complete a degree to access higher-level roles and specialisations in sectors like offshore wind storage and hydrogen facilities.
Entry requirements to get into university include:
• 3 A Levels at grades BBC to ABB, usually including Mathematics, Physics, or Engineering-related subjects.
As for degrees, you could take a course in subjects such as:
• Mechanical Engineering – This course teaches you how mechanical systems are designed, built, and maintained. In the Storage & Industrial Zone, this translates into creating the turbines, compressors, and cooling systems for hydrogen storage, as well as mechanical handling systems for battery units. You’ll study thermodynamics, materials science, fluid mechanics, systems design, and control engineering. You could study Mechanical Engineering at Swansea University. This degree teaches you how to maintain, troubleshoot, and optimise machines, engines, and energy systems, like those used in offshore wind farms, hydrogen storage tanks, and battery facilities. You’ll learn how materials perform under stress, how energy flows through systems, and how to apply maintenance strategies that keep technology safe, efficient, and reliable. Swansea University typically requires you to have at least AAB at A Level, including Mathematics.
Postgraduate study isn’t essential to become a Maintenance Engineer, but some people choose to continue their education after their first degree to move into more senior or specialist maintenance roles, especially in industries like offshore wind farms, hydrogen storage, and battery energy facilities.
Some postgraduate options include:
• Asset Management and Maintenance Engineering – This university course teaches you how to look after big, important machines and systems. Systems like offshore wind turbines, hydrogen storage tanks, and massive battery units. As a Maintenance
Engineer, your job is to keep these systems running safely and efficiently, spotting problems early and fixing them before they cause damage or delays. This course helps you achieve such skills by showing you how to plan inspections, manage repairs, and use technology to predict when equipment might need attention. It’s perfect for Maintenance Engineers who want to lead teams, manage whole projects, or work on new ways to make offshore energy systems last longer and perform better. This course can be found at Cranfield University, where they are looking for you to have at least a 2:2 to be able to access this postgraduate course.
Completing a master's degree can help you move into senior maintenance leadership roles, specialise in asset management, or work on research and development of new maintenance technologies for offshore and industrial energy sectors.
Maintenance and Operations Engineering Technician: (Level 3) - This apprenticeship teaches you how to maintain and repair mechanical, electrical, and fluid power systems that support energy generation and storage. You’ll learn how to carry out preventative maintenance on equipment like motors, pumps, valves, compressors, and turbines used at offshore hubs and storage facilities. You’ll also learn how to identify and fix faults using diagnostic tools, understand technical drawings and system schematics, and work safely around high-pressure hydrogen and electrical systems. This apprenticeship is ideal for anyone who wants to work hands-on, keeping offshore wind farm equipment,
hydrogen storage tanks, and battery storage units running safely and efficiently. It provides a strong technical foundation for a long-term career in maintenance engineering. You usually need 3-4 GCSEs at grades 4/C or above, including Mathematics, English, and Science, to apply.
