Industrial Coatings for Offshore Power | Protective Coatings | New Guard Coatings

Offshore power infrastructure operates in some of the most demanding environments for protective coatings.

Continuous exposure to moisture, salt, high humidity, wind and changing weather conditions can place significant demands on steelwork, equipment and industrial infrastructure. Without the correct surface preparation and coating system, exposed surfaces can become vulnerable to corrosion and coating deterioration.

New Guard Coatings supplies industrial and protective coating solutions for suitable offshore power applications, supporting businesses operating across energy, engineering and industrial infrastructure.

Protective Coatings for Offshore Environments

Offshore environments present challenges that are significantly different from many inland industrial applications.

Assets may be exposed to:

• Salt spray
• High humidity
• Continuous moisture
• Wind-driven rain
• UV exposure
• Temperature changes
• Atmospheric corrosion
• Mechanical wear

The coating system should be selected according to the individual asset, substrate and environmental conditions.

Suitable applications may include:

• Structural steel
• Equipment housings
• Generators
• Transformers
• Electrical boxes
• Metal enclosures
• Valves
• Fabricated components
• Support structures
• External infrastructure

Corrosion Protection for Offshore Steelwork

Steel used in offshore environments requires carefully considered protection.

Continuous exposure to moisture and chloride-containing environments can increase the risk of corrosion.

Suitable protective coating systems may be considered for compatible:

• Structural steel
• Platforms
• Support structures
• Handrails
• Equipment frames
• Fabricated assemblies
• External metal infrastructure

Before applying a new coating system, the existing condition of the steel should be assessed.

Factors to consider include:

• Existing corrosion
• Surface contamination
• Salt contamination
• Existing coatings
• Coating adhesion
• Surface damage

The required preparation and coating system will depend on the specific project requirements.

Surface Preparation for Offshore Steel

Surface preparation is a critical part of offshore coating projects.

Before applying a protective coating, surfaces should be assessed and suitably prepared to remove or address:

• Rust
• Corrosion products
• Oil and grease
• Dirt and debris
• Loose coatings
• Moisture
• Salt contamination

Depending on the substrate and coating specification, preparation may involve cleaning, mechanical preparation or abrasive blasting.

The surface should be clean, sound and suitably prepared before applying the selected coating system.

Salt Contamination & Chloride Removal

Salt contamination is an important consideration for offshore infrastructure.

Chloride salts can remain on exposed steel surfaces even when those surfaces appear clean to the eye. If residual salts are trapped beneath a newly applied coating system, they can contribute to corrosion and premature coating deterioration.

Where salt contamination is suspected, appropriate testing and removal methods should be considered as part of the preparation process.

Cleaning requirements will depend on the project specification and the condition of the substrate.

Simply removing visible dirt or corrosion does not necessarily mean that chloride contamination has been eliminated.

Coatings for Offshore Electrical Infrastructure

Offshore power systems can contain a wide range of electrical infrastructure requiring protection from demanding environmental conditions.

Potential applications can include compatible:

• Electrical boxes
• Control cabinets
• Metal enclosures
• Transformers
• Equipment housings
• External panels
• Support structures

These assets may be exposed to high levels of moisture, salt and atmospheric corrosion.

When carrying out maintenance work, the existing coating should be assessed before applying a new system.

Any corrosion, loose coating or contamination should be addressed through appropriate surface preparation.

Protective Coatings for Offshore Generators

Generators and associated equipment can contain metal housings and fabricated components exposed to demanding conditions.

Suitable protective systems may be considered for compatible:

• Generator housings
• Metal frames
• Equipment panels
• External components
• Fabricated assemblies

The correct system should be selected based on the equipment's operating environment and the level of exposure expected during service.

For maintenance projects, particular attention should be given to surface contamination and existing coating condition.

Coatings for Valves & Offshore Components

Offshore infrastructure often includes numerous smaller components that still require suitable protection.

Potential applications may include:

• Valves
• Equipment components
• Metal housings
• Pipe supports
• Fabricated assemblies
• Steel frames

Coating selection should consider more than the component itself.

The operating environment, substrate, surface temperature and potential chemical exposure may all influence the suitability of a particular coating system.

High-Performance Coating Systems for Offshore Applications

Offshore environments can require coating systems with performance characteristics suited to demanding conditions.

The most appropriate system will depend on factors including:

• The substrate
• Location of the asset
• Level of salt exposure
• Moisture and humidity
• Expected service environment
• Required durability
• Application conditions
• Maintenance requirements

There is no single coating suitable for every offshore application.

A system selected for one type of infrastructure may not be appropriate for another.

Maintaining Existing Offshore Infrastructure

Protective coatings can deteriorate over time due to environmental exposure and mechanical damage.

A maintenance project may involve:

• Inspecting the existing coating
• Identifying damaged areas
• Assessing corrosion
• Checking for contamination
• Removing loose material
• Preparing the substrate
• Applying a suitable maintenance coating system

The extent of preparation required will depend on the existing coating condition and the requirements of the new system.

Coating Compatibility

When applying a maintenance coating over an existing system, compatibility should be considered.

Before recoating, assess:

• The condition of the existing coating
• Whether it remains well adhered
• The type of existing system
• Surface contamination
• Compatibility with the proposed coating

Where compatibility is uncertain, additional assessment may be required before application.

Offshore Power Infrastructure & Long-Term Protection

Offshore assets can be difficult and costly to access for maintenance.

For this reason, coating selection should consider the expected operating environment and future maintenance requirements.

A suitable coating system can form part of a wider asset protection strategy designed to help protect compatible infrastructure against demanding environmental exposure.

The level of protection required will depend on the individual project, location and expected service conditions.
