At Offshore Cleaning, we provide specialist offshore cleaning services and across the UK, helping platforms, wind turbines, vessels, and subsea structures remain safe, operational, and compliant in harsh marine environments. From helidecks to turbine towers, our certified technicians use purpose-built systems to remove hazardous build-up, restore equipment surfaces, and support long-term asset integrity—safely and efficiently.

We deliver high-performance offshore cleaning with full environmental responsibility, using trained offshore crews, confined space and rope access specialists, and systems tailored to the demands of marine infrastructure.

What Are The Benefits Of Regular Offshore Cleaning?

Routine offshore cleaning services reduce corrosion, prevent slip and fire hazards, and help maintain operational efficiency.

Salt, oil, algae, and chemical residues can compromise equipment, sensor accuracy, and structural safety. Scheduled cleaning promotes crew safety, supports environmental compliance, and ensures critical systems remain inspection-ready and production-capable year-round.

What Does the Offshore Cleaning Process Involve?

An offshore cleaning service is tailored to structure type, contamination level, and location and includes:

• High- and ultra-high-pressure jetting – For removing marine growth, coatings, and oil deposits from decks and machinery.
• Steam cleaning and degreasers – Used in enclosed or sensitive zones like accommodation modules and tanks.
• Grit and dry ice blasting – Ideal for structural decontamination without water intrusion.
• ROV or diver-assisted cleaning – For subsea assets such as risers, pipelines, and splash zone components.
• Vacuum containment systems – Capture and isolate hazardous waste during cleaning.

How Much Does Offshore Cleaning Cost?

Offshore cleaning costs range from £5,000 to over £100,000, depending on the asset type, project scale, and access complexity.

Cleaning shallow decks or topsides is generally more economical than deep-sea riser or turbine work. Costs are influenced by factors such as crew size, equipment requirements, weather conditions, and vessel logistics.

How Often Should Offshore Facilities Be Cleaned?

Offshore cleaning is typically carried out every 6 to 12 months or during planned inspections, shutdowns, or maintenance cycles. Wind turbine blades may require seasonal cleaning.

Subsea assets are often serviced during ROV inspection campaigns. Frequency depends on environmental exposure, operating conditions, and regulatory schedules.

What Types of Offshore Structures Require Cleaning?

We clean a wide range of offshore structures, including:

• Oil & gas platforms – Including drill decks, storage tanks, and living quarters.
• Offshore wind turbines – Tower exteriors, nacelles, and blades.
• Subsea systems – Such as risers, pipelines, manifolds, and mooring chains.
• Support vessels – Including crew boats, supply ships, and accommodation units.

How Long Does Offshore Cleaning Take?

An offshore cleaning project can take several hours to multiple days, depending on asset type and size, contamination level and surface area, and weather windows and access logistics.

Large or remote sites may require phased scheduling and coordination with marine operations.

Are Eco-Friendly Offshore Cleaning Methods Available?

Our offshore cleaning prioritises low-toxicity products, closed-loop recovery systems, and non-abrasive techniques, such as biodegradable degreasers, which are used wherever possible.

 Other practices include checking whether waste is contained, logged, and disposed of via licensed marine carriers. The crew follows spill response and waste handling protocols in line with MARPOL and HSE standards.

What Equipment Is Used For Offshore Cleaning?

Our offshore cleaning solutions use structure-specific and environmentally compliant equipment, including:

• High-pressure and UHP jetting systems for deck and tank cleaning
• Steam cleaners and chemical sprayers for enclosed environments
• Dry ice or grit blasting units for paint and corrosion removal
• ROV systems and diver kits for subsea work
• Vacuum and recovery systems for spill-safe waste containment

What Safety Measures Are In Place During Cleaning?

All offshore cleaning is conducted under strict health, safety, and environmental controls, such as the crews holding certifications in BOSIET, OPITO, H2S awareness, and IRATA rope access.

Each project includes risk assessments, emergency response planning, and confined space protocols. Work is coordinated with platform safety officers and complies with IMO, HSE, and client safety standards.
