Industrial Drone Cleaning
Storage tank exteriors, pipe racks, silos, stacks and process buildings cleaned from the air — without scaffolding a live plant or sending crews into structures at height.
Industrial drone cleaning starts from S$4,000 depending on structure, access complexity and site clearance. The value on an industrial site is rarely the cleaning price — it is avoiding the scaffolding, permits-to-work and access downtime that conventional cleaning of a live plant requires.
Key takeaways
- Price: From S$4,000 by structure and clearance requirements.
- Jurong Island needs JTC clearance on top of the CAAS permit - longer lead time.
- Hazardous area classification is the real constraint; standard drones are not zone-rated.
- Scaffolding avoidance is usually worth more than the cleaning itself on a live plant.
- Not confined space. We clean exteriors; internal vessel work is a different discipline.

Structures we clean
| Structure | Suitability | Notes |
|---|---|---|
| Storage tank exteriors | Excellent | Large continuous curved surfaces, open approach. |
| Silos | Excellent | Same geometry advantage as tanks. |
| Process building facades | Excellent | Standard facade work in an industrial setting. |
| Chimneys and stacks | Good | Subject to plant status and thermal conditions. |
| Cooling tower exteriors | Good | Exterior shell only; internals are separate work. |
| Pipe racks and structural steel | Partial | Congested geometry limits coverage; hybrid likely. |
| Internal vessels and confined spaces | Not applicable | Different discipline entirely - not aerial work. |
Jurong Island and secured estates
Jurong Island is Singapore's petrochemical hub and a restricted estate. Drone operations there require JTC security clearance in addition to the CAAS Activity Permit, plus the facility operator's own site approval and permit-to-work.
Practically, that means longer lead times than a commercial building — plan six to eight weeks rather than three to four — and additional administrative cost for the clearance process and escorted site access. We handle the applications; the operator controls the schedule.
Hazardous area classification
This is the genuine limitation on industrial drone work and it is worth being blunt about. Standard cleaning drones are electrical equipment and are not certified for classified hazardous zones where flammable atmospheres may be present.
What that means in practice. Work is either scheduled around plant status — during shutdown or turnaround when the area is gas-free and certified — or restricted to non-classified parts of the site. This is assessed with the operator's HSE function before any quote is firmed. Any contractor who does not raise classification before quoting has not thought about your site.
Industrial cleaning cost
| Scope | Typical price (SGD) | Notes |
|---|---|---|
| Single storage tank exterior | From S$4,000 | By diameter and height |
| Process building facade | From S$4,000 | Standard facade rates apply |
| Tank farm, multiple vessels | From S$6,000 | Shared mobilisation |
| Jurong Island / secured estate | + clearance cost | Longer lead time, escorted access |
| Shutdown / turnaround window | Quoted per programme | Scheduled with plant status |
Industrial roofs are covered separately on warehouse and factory roof cleaning.
Frequently asked questions
Can drones clean on Jurong Island?
Yes, with clearance. Jurong Island operations require JTC security clearance in addition to the standard CAAS Activity Permit, plus site-specific approval from the facility operator. Lead times are longer than for ordinary commercial sites.
What industrial structures can drones clean?
Storage tank exteriors, pipe racks, structural steel, silos, chimneys and stacks, cooling tower exteriors, conveyor structures and process building facades. Anything with an open approach and no requirement for physical contact work.
Is drone cleaning allowed near live process plant?
It depends on the facility hazardous area classification. Standard cleaning drones are not rated for classified hazardous zones, so work is scheduled around plant status or restricted to non-classified areas. This is assessed case by case with the operator.
How much does industrial drone cleaning cost?
Industrial cleaning typically starts from S$4,000 depending on structure type, access complexity and clearance requirements. Secured-estate sites carry additional cost for clearance administration and escorted access.
