At Offshore Duct Cleaning, we deliver compliant, confined-space-ready duct cleaning services in Thetford IP25 7 tailored to the unique demands of offshore facilities operating in UK waters and beyond.

Specialist offshore duct cleaning in Thetford plays a vital role in maintaining air quality, system efficiency, and safety on offshore platforms, vessels, FPSOs, rigs, and accommodation modules.

Since offshore environments are exposed to salt-laden air, high humidity, and confined spaces, ventilation systems can quickly accumulate dust, grease, mould, and corrosion, posing a risk to both equipment and personnel.

What Is Offshore Duct Cleaning?

Offshore duct cleaning in Thetford involves the inspection, cleaning, and disinfection of ventilation and extraction ductwork on offshore platforms, oil rigs, support vessels, and marine structures.

As ventilation systems in these settings are critical for crew welfare and operational safety, we remove contaminants such as dust, grease, salt, and microbial growth using specialist equipment. 

Cleaning may include air handling units, supply and extract ductwork, galley systems, and HVAC components within living quarters and technical areas.

All work is performed to offshore safety standards and includes full documentation.

How Much Does Offshore Duct Cleaning in Thetford Cost?

The cost of professional offshore duct cleaning services in Thetford is from £950 to £6,000.

The cost of offshore duct cleaning in Thetford varies depending on several key factors, including the type of duct system (e.g. HVAC, galley extraction), the length and complexity of the duct runs, access restrictions, and whether the cleaning is performed during shutdown or live operations.

For smaller systems, such as single galley extraction ducts or short HVAC runs in accommodation modules, costs typically start from £950 to £1,500 per system.

For more complex duct networks across multiple levels or compartments (including AHU supply and extract systems), pricing generally ranges between £2,500 and £6,000, depending on the number of systems, cleaning duration, and offshore logistics involved.

For long-term maintenance, we also offer multi-visit cleaning schedules for large offshore installations, with reduced rates applied across multiple duct systems.

We provide fixed quotes based on asset drawings, system schematics, or site survey data. 

Why Is Duct Cleaning Important Offshore?

Duct cleaning offshore is essential because unmaintained systems can lead to poor air quality, equipment overheating, fire hazards, and non-compliance with HSE and offshore asset integrity standards.

Since ductwork can harbour dust, mould, salt deposits, and grease, particularly in galleys and engine-adjacent areas, regular cleaning prevents airflow restriction, odour complaints, and microbial contamination.

It also supports offshore HVAC efficiency, protects sensitive electronics, and contributes to occupational health requirements under HSE and UK Oil & Gas guidelines.

What Types of Offshore Facilities Do You Service?

We provide offshore duct cleaning in Thetford for a wide range of installations, including:

Oil and gas platforms, FPSOs (Floating Production Storage and Offloading), offshore wind substations, jack-up rigs, accommodation barges, and maritime support vessels.

Whether docked or live, we carry out cleaning during scheduled maintenance windows or as part of wider shutdown campaigns. Our team is trained for offshore deployment, including BOSIET, MIST, and confined space certification.

How Often Should Offshore Ducts Be Cleaned?

The recommended frequency for offshore duct cleaning in Thetford varies depending on system use, environmental exposure, and safety risk.

Galley extraction systems typically require cleaning every 3 to 6 months, while HVAC supply and extract ductwork should be inspected and cleaned at least annually, or more frequently in harsh or high-load environments.

We provide condition-based assessments and can integrate duct cleaning into existing offshore PPM (Planned Preventive Maintenance) schedules.

What Are the Benefits of Offshore Duct Cleaning?

Offshore duct cleaning improves safety, efficiency, and compliance across remote installations:

• Reduces fire risk in galley and machinery extraction systems
• Improves air quality and crew comfort
• Prevents salt, grease, and moisture-related corrosion
• Ensures HVAC systems perform at design capacity
• Supports compliance with HSE and marine standards
• Minimises odours, microbial growth, and allergen exposure
• Contributes to offshore maintenance and inspection records

Since offshore environments are isolated and high-risk, preventative maintenance through duct cleaning is essential to operational integrity.

Are Your Operatives Certified for Offshore Work?

All personnel involved in offshore duct cleaning in Thetford are fully certified for offshore deployment.

Since offshore environments require strict health and safety compliance, every operative holds a valid BOSIET (Basic Offshore Safety Induction and Emergency Training), MIST (Minimum Industry Safety Training), and OGUK medical certification.

We also supply trained operatives with confined space entry and working at height qualifications, allowing us to complete cleaning tasks in challenging or restricted environments without delay.

Can You Perform Duct Cleaning During Offshore Shutdowns?

We regularly provide offshore duct cleaning in Thetford during scheduled maintenance periods or planned shutdowns.

Since shutdowns provide an ideal opportunity to access HVAC systems, riser shafts, and plantroom ventilation without interrupting live operations, our teams are available to support full ductwork decontamination, inspection, and validation within tight turnaround windows.

We liaise directly with on-site asset managers and maintenance coordinators to align with your existing maintenance schedule and safety protocols.

Do You Clean Galley Extraction Systems Offshore?

Galley extraction is one of the most critical aspects of our offshore duct cleaning in Thetford service.

Since grease build-up in kitchen ductwork is a significant fire hazard, especially on enclosed, manned platforms, we perform detailed degreasing of extraction hoods, canopies, riser ducts, and fans using industry-approved degreasers and mechanical scraping methods.

We also remove and clean grease filters, replace damaged components if needed, and provide photographic evidence and fire risk compliance documentation upon completion.

What Equipment Do You Use for Offshore Duct Cleaning?

We use a range of ATEX-rated and offshore-compliant cleaning tools for all offshore duct cleaning in Thetford operations.

Our equipment includes rotary brush systems, HEPA-filtered negative air vacuums, high-reach flexible rods, and borescopes for internal duct inspection. 

Where microbial contamination or mould is detected, we also apply hospital-grade antimicrobial treatments safe for use in enclosed environments.

All equipment is compact, portable, and selected to meet offshore transport and safety restrictions.

Do You Provide Reports and Documentation for Compliance?

Every offshore duct cleaning service in Thetford includes full post-clean documentation suitable for HSE audits, maintenance logs, and insurance compliance.

Our standard reporting includes pre- and post-clean photos of ductwork and components, cleaning methods and materials used, system condition observations, recommendations for remedial work or further access points and certificates of hygiene or fire compliance (e.g. TR19 guidelines for galley systems).

All documentation is delivered in digital format for easy sharing with offshore maintenance teams and asset managers.
