Tank, Vessel and Column Cleaning Services

RGL Services delivers tank vessel and column cleaning across the UK using ultra-high-pressure water jetting at up to 2,800 bar. Operating since 1984, we remove product residues, scale, sludge and polymers from storage tanks, process vessels and columns using no-man-entry tank cleaning methods. Rotating 3D rotating jet head cleaning systems are deployed through existing access points so operators stay outside the vessel.

As specialist tank cleaning contractors, we combine remotely operated 3D jetting heads with high-flow UHP systems, cleaning walls, floors, roofs, agitators, baffles and complex internal geometries. Rentajet is mobilised nationwide, with Romsey, London and Manchester coverage and a direct response service for shutdowns and product changeovers.

Why Operators Specify No-Man-Entry Tank Cleaning Over Manual Entry

Manual confined-space cleaning of tanks and vessels carries significant risk. It exposes personnel to hazardous atmospheres and residues, demands breathing apparatus, standby rescue teams and gas monitoring, and extends downtime while permits and entries are managed.

No-man-entry tank cleaning removes that constraint. Rotating 3D rotating jet head cleaning systems deliver high-impact water jets in every direction while operators stay outside the vessel. The process uses only water, so there are no chemicals to neutralise.

That is what gets industrial tank cleaning specified on live and decommissioned tanks, reactors and columns where personnel safety, product quality and turnaround time all have to be protected at once.

Our Tank Vessel and Column Cleaning Services

Rentajet operates a full range of industrial tank cleaning services configured to the vessel, the residue and the access on site.

No-Man-Entry Tank Cleaning

Remotely operated cleaning using rotating 3D rotating jet head cleaning systems through existing access points. Operators remain outside the tank throughout.

Process Vessel and Reactor Cleaning

Cleaning of pressure vessels, reactors and mixing vessels including agitators, shafts, blades and baffles. Removes product residues, polymers and scale without damaging internal fittings.

Distillation and Process Column Cleaning

Internal cleaning of distillation and process columns, including trays and packing where access allows. Restores throughput and prepares columns for inspection.

Tank Floor and Sludge Removal

Removal of settled sludge, heavy residues and product from tank floors using UHP jetting and vacuum recovery.

Pre-Inspection and Decontamination Cleaning

Cleaning ahead of statutory inspection, decommissioning or product changeover, restoring internal surfaces to a clean, residue-free condition.

Bespoke Vessel Cleaning Rigs

Engineered deployment heads for vessels with restricted access or unusual internal geometry.

Benefits of No-Man-Entry Tank Cleaning

No-man-entry UHP vessel cleaning changes the safety, environmental and downtime profile of vessel cleaning.

Enhanced safet

No-man-entry systems minimise confined-space risk and remove operator exposure to hazardous atmospheres.

Chemical-free and abrasive-free

Uses only clean water, no chemicals to neutralise and no abrasive media to recover.

Easy waste management

Wastewater typically compatible with existing site separators or drainage systems.

Reduced downtime

Fast cleaning supports quicker product changeovers and faster inspection readiness. Bullet 5

Full-geometry coverage

Rotating 3D heads reach walls, floors, roofs, agitators, baffles and complex internal surfaces.

Consistent results

Restores original surface conditions for operational efficiency and regulatory compliance.

UHP vessel cleaning vs Manual and Chemical Methods

Manual entry and chemical cleaning remain common where specialist water jetting is not available. They carry confined-space risk, chemical handling and waste-disposal burdens, and often longer downtime.

Factor No-Dig UHP Removal Excavation
Surface disturbance None, in-pipe only Major, full dig and reinstatement
Road closures Usually none Often required
Effective on concrete and piles Yes, precision cutting Yes, but by digging out
Minimum pipe size From 95mm diameter Limited by access to dig
Restoration of flow Fast Slow, after reinstatement
Environmental impact Low High, spoil and disturbance
Cost on buried services Lower total cost High, with reinstatement
Disruption to operations Minimal Significant

Applications of Tank Vessel and Column Cleaning

UHP vessel cleaning is specified wherever internal residues need removing without man-entry, chemicals or surface damage.

Storage Tanks and Terminals

No-man-entry tank cleaning of crude, product and chemical storage tanks ahead of inspection, changeover or decommissioning.

Process Vessels and Reactors

Cleaning of reactors, mixing vessels and pressure vessels in chemical, pharmaceutical and manufacturing plants.

Distillation and Process Column Cleaning

Internal cleaning of distillation and process columns to restore throughput and prepare for inspection.

Our Tank Vessel and Column Cleaning Process

Rentajet follows a five-step process on every cleaning mobilisation.

01. Site Survey and Cleaning Specification

We survey the vessel, the residue, the access points and the surrounding plant, and confirm the cleaning method and waste route. Method statement and risk assessment produced to WJA Code of Practice.

02. Mobilisation and Set-Up

UHP pumps, 3D jetting heads and vacuum recovery plant mobilised to site. Pump units run at up to 2,800 bar.

03. Deployment and Commissioning

Jetting heads deployed through existing access points and aligned to the internal geometry. Pressure, head rotation and dwell confirmed before bulk cleaning.

04. No-Man-Entry Tank Cleaning

Rotating heads clean the full internal surface while wastewater and residue are vacuumed and routed to the agreed waste system.

05. Inspection and Handover

Cleaned vessel inspected, photographic record issued, vessel handed over ready for inspection, relining or return to service.

Tank Vessel and Column Cleaning FAQs

Cost depends on vessel size, residue type and volume, access and waste-disposal requirements. Contact us for a project-specific quotation.

For the majority of projects, no. We prioritise no-man-entry tank cleaning by deploying rotating 3D rotating jet head cleaning systems through existing access points while operators stay outside.

No. Our methods use only clean water at high or ultra-high pressure. The wastewater is typically compatible with existing site separators or drainage systems.

Product residues, scale, sludge, polymers and build-up on walls, floors, roofs and internal fittings. Rotating 3D rotating jet head cleaning reaches agitators, shafts, blades and baffles.

Yes. Pre-inspection cleaning is one of the most common reasons the service is specified. We clean internal surfaces to a residue-free condition and hand over a photographic record.
