Marine and Offshore Decontamination

Ships and offshore structures operate in some of the harshest environments, where exposure to sea water, big waves and high winds, can severely compromise onboard systems. Marine decontamination services are essential for restoring vessel integrity and safeguarding critical equipment.

BELFOR provides comprehensive marine cleaning services and offshore cleaning solutions tailored to the demanding needs of vessels, oil rigs, and floating facilities. From engine rooms to the bridge, we handle contamination scenarios caused by fire, water, or prolonged marine exposure. Our certified teams use specialised cleaning methods to restore high-value electrical and mechanical assets, with minimal disruption to operations.

Whether at dock or mid-voyage, BELFOR’s trusted marine and offshore teams are ready to respond—locally in Singapore or globally—ensuring vessels stay seaworthy and operations remain uninterrupted.

What We Clean Onboard Vessels and Offshore Platforms

We also restore high-value items such as transformers, variable frequency motor drives, and low/medium voltage switchgear — critical components that require expert care.

Comprehensive Marine and Offshore Decontamination Services

BELFOR delivers specialised decontamination solutions for vessels and offshore platforms affected by contamination, corrosion, or operational disruptions. Our services are designed to restore structural integrity, reduce downtime, and maintain compliance with international maritime safety and environmental standards.

Hull Cleaning

Our hull cleaning service targets contamination resulting from fire residues, oil spills, or seawater intrusion. Using precision cleaning methods and corrosion-control treatments, BELFOR removes soot, salt, and chemical deposits from internal and external hull surfaces. This process helps prevent structural degradation, supports coating longevity, and prepares vessels for safe re-entry into service.

Tank Cleaning

BELFOR’s tank cleaning services cover fuel, ballast, and cargo tanks contaminated by oil residues, sludge, or hazardous materials. Our teams apply controlled cleaning and neutralisation techniques to eliminate combustible and corrosive substances, ensuring a safe environment for inspection, repair, and continued operation. All processes are conducted in accordance with international marine and safety regulations.

Equipment Cleaning

From engines and turbines to transformers and control systems, BELFOR restores critical onboard and offshore machinery through targeted equipment cleaning methods. Depending on the type of contamination, our specialists employ dry-ice blasting, chemical cleaning, or high-pressure washing to remove pollutants while preserving mechanical precision and electrical insulation integrity.

Oil Rig Cleaning

Operating in harsh offshore conditions exposes rigs to multiple contaminants, including hydrocarbons, salt deposits, and drilling residues. BELFOR provides comprehensive oil rig cleaning solutions that encompass deck areas, process systems, and accommodation modules. By combining industrial-grade decontamination with environmental safety protocols, we help operators maintain platform safety, prevent corrosion, and extend operational lifespan.

This integrated service model enables vessel operators and offshore companies to return to safe and efficient operations more quickly while maintaining asset reliability over time.

Our Marine & Offshore Decontamination Process

Our structured process ensures safe and complete decontamination of marine and offshore assets. Every step is designed to minimise disruption, reduce equipment downtime, and ensure a return to safe operational conditions.

• Site Assessment – We begin with a detailed inspection of affected areas, identifying impacted systems, materials, and operational zones.
• Contamination Analysis – Our team evaluates the type and severity of contamination — whether from sea water, soot, oil residue, or chemical exposure.
• Dry/Wet Cleaning Selection – Based on material sensitivity, we choose between dry selective (single step) or wet selective (multi steps) for precise decontamination.
• Onboard Cleaning – BELFOR’s mobile teams are equipped to work while vessels are docked or en-route, and platforms are on location or en-route, maintaining flexibility without compromising service quality.
• Post-Decontamination Inspection & Reporting – A thorough inspection is conducted to confirm cleanliness, followed by a report documenting restored systems and areas.

This process allows BELFOR to restore sensitive systems safely, maintain regulatory compliance, and help clients resume normal operations quickly and with confidence.

Frequently Asked Questions

What are marine cleaning services?

Marine cleaning services refer to professional cleaning and decontamination solutions for ships, vessels, and offshore platforms. These services include hull cleaning, tank cleaning, and equipment restoration to remove oil, sludge, corrosion, and contaminants that affect performance and safety.

Why is regular hull cleaning necessary for vessels?

Regular hull cleaning helps reduce drag, improve fuel efficiency, and prevent corrosion caused by salt and biofouling. It also ensures that vessels remain compliant with environmental regulations and maintain optimal performance during operation.

What is included in offshore cleaning services?

Offshore cleaning services typically cover the decontamination of oil rigs, platforms, and support vessels. This includes cleaning structural surfaces, tanks, pipelines, and accommodation areas to maintain hygiene, ensure safety, and comply with environmental regulations.

How often should tank cleaning be carried out on ships or rigs?

The frequency of tank cleaning services depends on the type of cargo or fuel stored and the operating conditions. Regular cleaning helps prevent the accumulation of sludge, corrosion, and contamination, which can impact tank safety and efficiency.

Are marine cleaning services environmentally friendly?

Yes. Professional marine cleaning services adhere to international environmental and maritime safety standards, including MARPOL and IMO guidelines. BELFOR uses controlled cleaning methods and approved waste disposal systems to minimise ecological impact.

Can cleaning be performed while the vessel is in operation?

Certain cleaning procedures, such as minor surface cleaning or equipment decontamination, can be performed during operations if safety protocols allow. However, more extensive cleaning tasks, such as tank or hull cleaning, are usually conducted while the vessel is docked or under controlled conditions.

How does BELFOR ensure safety during offshore cleaning services?

BELFOR follows strict procedures for confined-space entry, including hazard assessments and permit-to-work systems. Our teams are trained in offshore safety standards to ensure every cleaning operation is performed with full compliance and minimal risk.

What types of contaminants can marine and offshore cleaning remove?

Marine cleaning services can remove oil residues, soot, sludge, rust, scale, and biological growth. Offshore cleaning also addresses contaminants like drilling mud, salt deposits, and hydrocarbon films that may compromise operational integrity.

How long does a typical offshore cleaning project take?

The project duration varies depending on the size of the structure, the level of contamination, and the scope of cleaning. BELFOR’s teams are equipped to handle both rapid-response clean-ups and large-scale offshore restoration efficiently, minimising downtime.

Why should I choose BELFOR for marine and offshore cleaning?

BELFOR combines technical expertise, environmental compliance, and rapid deployment capabilities to deliver reliable offshore and marine cleaning services. Our integrated approach ensures complete restoration, safety assurance, and long-term operational performance.
