Ormonde was selected for the project based on our extensive experience in hazardous tank cleaning, advanced industrial cleaning technologies, and our ability to develop tailored cleaning solutions for complex industrial environments. One of the key requirements of the project was the safe management of hazardous gases and vapors during the cleaning operation, including the use of specialist gas and vapor scrubbing systems to protect both onsite personnel and the surrounding environment.
At Ormonde, we understand that no two tank cleaning projects are the same. Tank size, stored product, sludge condition, hazardous atmosphere classification, local environmental requirements, and operational limitations all influence the safest and most efficient cleaning method. For this reason, our teams develop tailor-made industrial cleaning solutions designed around the specific operational and safety challenges of each project.
The Challenges of Gas Storage Tank Cleaning
Cleaning large gas storage tanks requires careful planning, specialist safety systems, and experienced operational teams. Over time, gas storage systems can accumulate:
- Sludge and sediments
- Hazardous residues
- Hydrocarbon contamination
- Corrosive deposits
- Hazardous vapors and gases
If not properly managed, these contaminants can affect operational safety, equipment performance, fuel quality, and long-term asset reliability.
Gas tank cleaning projects often involve:
- Hazardous atmospheres
- EX and ATEX environments
- Confined space operations
- Gas freeing and vapor management
- Environmental protection requirements
- Specialist sludge recovery and waste handling
For these reasons, industrial gas tank cleaning should only be carried out by experienced industrial cleaning specialists using the correct technology and safety procedures.
How Is a Gas Storage Tank Cleaned?
The cleaning process for gas storage tanks typically includes several critical stages designed to ensure both operational safety and cleaning quality.
1. Vapor & Gas Freeing (Degassing)
Before cleaning operations begin, the tank must be mechanically vented and degassed to safely remove hazardous and explosive vapors. Continuous gas monitoring is carried out until the tank reaches a safe Lower Explosive Limit (LEL).
Ormonde also utilizes specialist gas and vapor scrubbing systems where required to protect onsite personnel and minimize environmental impact.
2. Sludge & Waste Removal
Sludge, sediments, and hazardous residues are removed using:
- High-powered suction excavators (saugbaggers)
- Industrial vacuum trucks
- EX and ATEX-certified vacuum systems
- Pumping and sludge transfer systems
Depending on the project requirements, Ormonde can also provide robotic and non man entry sludge removal solutions.
3. Internal Tank Washing & Cleaning
The internal tank surfaces are cleaned using:
- High-pressure water jetting
- Automated tank cleaning systems
- Chemical cleaning agents
- Robotic cleaning technologies
- Hot water cleaning systems
These systems are selected based on the contamination level, stored product type, and tank design.
4. Inspection & Safety Verification
Once cleaning operations are completed, confined space inspections and safety verification procedures are carried out to assess:
- Internal tank condition
- Corrosion or damage
- Wall and seam integrity
- Remaining contamination levels
This process ensures the tank is prepared for maintenance, inspection, repair, or return to operation.
Traditional & Robotic Tank Cleaning Solutions
The Ormonde team has extensive experience in:
- Gas storage tank cleaning
- Fuel tank cleaning
- Oil tank cleaning
- Industrial gas pipe cleaning
- Boiler and gas technology cleaning
- Hazardous industrial cleaning operations
We provide both traditional industrial cleaning methods and advanced robotic tank cleaning solutions including:
- Non man entry cleaning
- Reduced man entry cleaning
- EX Zone Zero robotic cleaning
- Robotic water jetting systems
- Remote-operated sludge recovery technologies
By combining robotic systems with suction excavation, pumping technologies, and advanced safety systems, Ormonde can safely manage complex gas tank cleaning projects while reducing confined space exposure and operational risk.
Safety First Approach
Safety is the foundation of every Ormonde tank cleaning project.
Gas storage tank cleaning involves potentially hazardous atmospheres, explosive vapors, confined spaces, and difficult operational environments. Every project therefore begins with a detailed operational risk assessment carried out together with our cleaning teams to fully understand the project risks and select the safest operational approach.
Our specialist safety systems include:
- Gas detection and monitoring systems
- Vapor and gas scrubbing technologies
- Fresh air breathing systems
- High-pressure and low-pressure breathing air systems
- ATEX-certified equipment
- Heat monitoring systems
- Specialist confined space PPE and safety equipment
This safety-first approach allows Ormonde to complete complex industrial cleaning projects to the highest operational and environmental standards.
