Trust CESCO for dependable tank cleaning, chemical tank cleaning, and purifier desludging services. We help you maintain regulatory compliance and operational efficiency by ensuring storage tanks are residue-free and safe.
Tank cleaning and de-sludging is delivered under CESCO’s industrial waste management services in Singapore, including safe handling and disposal of the oily sludge and residues removed.
Tank desludging is the removal of accumulated sludge and sediment from the bottom of storage tanks, process vessels, and oil purifiers. Over time, heavy hydrocarbons, settled solids, water bottoms, rust, scale, and other residues build up as a dense sludge layer. Left in place, this sludge reduces usable tank capacity, contaminates stored product, promotes corrosion beneath the deposit, and — in fuel and lube oil purifiers — steadily lowers separation efficiency. Desludging restores capacity, protects product quality, and keeps equipment running as intended.
CESCO provides desludging services in Singapore for industrial and marine facilities, covering everything from large storage-tank sludge removal to purifier desludging on fuel and lube oil separators. Our team handles the full scope — isolating and gas-freeing the tank, removing and collecting the sludge, cleaning the interior, and arranging licensed disposal of the waste removed. Whether you need a one-off clean-out ahead of an inspection or scheduled desludging as part of ongoing maintenance, we work to the standard each tank and product demands.
A controlled sequence keeps the work safe and the results verifiable:
We review the tank, its contents, and its history, then isolate it and put safety controls in place.
The tank is ventilated and made safe for entry where confined-space work is required.
Sludge is removed using the appropriate method — manual, mechanical, high-pressure water jetting, vacuum extraction, or chemical cleaning — depending on the tank and residue type.
The interior is cleaned to the required standard and inspected before being returned to service.
The sludge and residues removed are collected and disposed of through CESCO’s licensed waste management services, so you have a clear disposal trail.
CESCO desludges and cleans a wide range of equipment, including crude and product storage tanks, fuel and diesel tanks, chemical storage tanks, marine cargo and slop tanks, process vessels, and fuel and lube oil purifiers. We manage oily sludge, tank bottoms, settled solids, scale, and chemical residues — routing each to the correct handling and disposal pathway rather than treating it generically.
CESCO combines tank cleaning, desludging, and licensed waste disposal under one provider, so a single team takes the tank from full of sludge to clean, inspected, and compliant — with the waste properly handled. Our experience across industrial and marine facilities in Singapore means each scope is planned to the right method, safety standard, and disposal route for the tank and residue involved.
Tank cleaning and desludging often involve confined-space entry and hazardous residues, so every scope is carried out under our QEOHS framework with permit-to-work discipline and documented procedures. The sludge and residues removed are a regulated waste stream, and CESCO manages their disposal through licensed routes — and can provide decontamination and steam cleaning where equipment needs further treatment.
A tank cleaning service covers isolating and gas-freeing the tank, removing product residues, scale, and sludge, cleaning the interior to the required standard, inspection, and licensed disposal of the waste removed.
A desludging service removes accumulated sludge and sediment from the bottom of tanks, vessels, and purifiers. It restores capacity, protects stored product from contamination, and prevents corrosion beneath the deposit.
It depends on the product stored, the rate of sludge build-up, and inspection or compliance requirements. Many facilities clean or desludge on a schedule or ahead of an inspection; CESCO can advise on a suitable interval.
Yes. CESCO cleans and desludges industrial storage tanks, chemical tanks, process vessels, marine cargo and slop tanks, and fuel and lube oil purifiers.
They are a regulated waste stream. CESCO collects and disposes of them through licensed waste management routes, giving you documentation of proper disposal.
CESCO acknowledges the recent waste disposal incident in Malaysia and expresses its deepest regret over the matter. We have taken immediate steps to work in full cooperation with the relevant environmental and regulatory authorities to resolve the situation and to prevent any recurrence.
Following a comprehensive internal investigation, it was determined that the incident stemmed from actions taken by third-party contractors that violated our environmental compliance standards and internal governance protocols. The actions were not sanctioned by CESCO and are entirely inconsistent with our values of integrity, sustainability, and corporate accountability.
As part of our response, Mr. Tan Eng Yong — who was involved in the contractor selection process — has ceased all affiliation with CESCO with effect from 25 April 2025. This decision was made to reinforce our uncompromising stance on ethical conduct and responsible stewardship.
CESCO upholds the highest standards of environmental protection, transparency, and operational integrity. We are committed to strengthening our compliance framework and will continue to take all necessary measures to safeguard the trust placed in us by our stakeholders, communities, and regulatory partners.
We thank the authorities for their continued guidance and oversight during this time.
