Composite materials play a vital role throughout the oil and gas industry, providing lightweight, corrosion-resistant and high-performance solutions for both onshore and offshore operations. Used in exploration, production, processing, transportation and storage, composites help operators improve safety, reduce maintenance costs and extend the service life of critical infrastructure in some of the world’s harshest operating environments.
Glass fibre reinforced polymer (GFRP) is the most widely used composite material in the sector due to its excellent corrosion resistance and cost-effectiveness, while carbon fibre composites are increasingly adopted for high-strength, weight-critical applications. Composite technologies also continue to support the industry’s transition towards lower-carbon energy systems, including carbon capture, hydrogen and offshore renewable energy.
Offshore Platforms and Infrastructure
Composite materials are widely used on offshore installations where resistance to seawater, chemicals and harsh weather conditions is essential.
Typical applications include:
- Grating and walkways
- Handrails and guardrails
- Stairways and access platforms
- Decking systems
- Cable trays and cable management
- Structural supports
- Pipe bridges
- Equipment enclosures
- Blast walls
- Fire protection systems
Compared with traditional steel, composites offer excellent durability with minimal maintenance, reducing both downtime and lifecycle costs.
Pipework and Process Systems
One of the largest applications for composites is in pipework and fluid handling systems, where corrosion resistance and long service life provide significant operational advantages.
Applications include:
- Process pipework
- Flowlines
- Produced water systems
- Seawater intake systems
- Chemical transfer lines
- Cooling water systems
- Firewater systems
- Drainage systems
- Composite repair wraps for pipelines
- Valves and fittings
Glass reinforced epoxy and other fibre-reinforced pipe systems are widely used in corrosive environments where metallic systems would require frequent maintenance or replacement.
Tanks and Storage
Composite materials are extensively used for the storage and handling of chemicals, fuels and process fluids.
Applications include:
- Chemical storage tanks
- Pressure vessels
- Process vessels
- Scrubbers
- Silos
- Secondary containment systems
- Bunds
- Tank covers
Their resistance to aggressive chemicals makes composites particularly suitable for handling corrosive process media.
Subsea Applications
The subsea environment presents some of the most demanding engineering challenges, where lightweight, corrosion-resistant materials deliver significant operational benefits.
Applications include:
- Riser systems
- Umbilical components
- Buoyancy modules
- Subsea enclosures
- Connector housings
- ROV and AUV structures
- Instrument housings
- Cable protection systems
The reduced weight of composite components simplifies installation and can lower vessel and lifting requirements during offshore operations.
Inspection, Repair and Maintenance
Composite materials are increasingly used to repair and reinforce ageing infrastructure without the need for costly replacement.
Applications include:
- Pipeline repair systems
- Pressure vessel repairs
- Structural reinforcement
- Corrosion protection
- Leak containment systems
- Protective coatings and liners
Composite repair technologies can often be installed while equipment remains in service, reducing downtime and extending asset life.
Why Use Composites in Oil and Gas?
Composite materials offer significant technical and economic advantages across the oil and gas value chain.
Key benefits include:
- Outstanding corrosion and chemical resistance
- High strength-to-weight ratio
- Reduced installation and transportation costs through lower weight
- Excellent fatigue performance in demanding environments
- Lower maintenance requirements and extended asset life
- Resistance to seawater, moisture and harsh weather
- Improved health and safety through easier handling
- Electrical and thermal insulation properties
- Design flexibility for complex systems and components
- Compatibility with advanced inspection, repair and monitoring technologies
As the energy sector evolves, composite materials continue to support both traditional oil and gas operations and the wider energy transition. The expertise developed in demanding offshore environments is increasingly being applied to carbon capture and storage (CCS), hydrogen infrastructure, offshore wind and other low-carbon energy technologies, ensuring composites remain a key enabling material for the future energy landscape.
