Industrial Tank Cleaning FAQ

Why Invest in Industrial Tank Cleaning and How Can it Benefit Your Business?

To help you understand if your fuel system can benefit from industrial tank cleaning, this FAQ includes everything there is to know about the restoration process, including the methodology, what it does and how it will benefit your business.

Neglected industrial fuel tanks can be hazardous and expensive to bring back to compliant standards. Without regular cleaning, fuel contaminants can decrease a tank’s integrity over time, leading to equipment breakages, unplanned downtime and an increased likelihood of spills.

What is industrial tank cleaning?

Over time, fuel reduces in quality and compromises a tank’s integrity. Industrial tank cleaning is key to mitigating a whole host of common problems which can be found with new and old tanks, as well as reducing the risk of oil leaking into the environment.

Industrial tank cleaning is an intrinsic part of many businesses’ fuel maintenance plans and can help you to avoid huge fines by leveraging our environmental expertise.

Why is tank cleaning important?

Fuel contamination, sludge build-up and tank corrosion are all common issues that can occur without regular tank cleaning. Sludge can block the tank’s outlets, making the vessel extremely dangerous, reducing efficiency and destroying the stored fuel.

Tank cleaning is an integral part of a planned preventative maintenance programme to help prolong the lifespan of the stored contents, the tank itself, as well as to reduce the risk of oil spills and leaks.

There are many reasons for needing an industrial tank clean, including:

  • Changing a stored product
  • Your fuel is contaminated
  • Your tank is damaged
  • Your tank is being decommissioned
  • Your fuel or tank is being transported
  • As part of regular maintenance to extended shelf life
What does industrial tank cleaning involve?

Before a tank can be cleaned, our engineers will visit your site, discuss your requirements and inspect your fuel storage system to determine the most cost-effective solution. This ensures we can diagnose and repair any storage tank faults with minimal disruption.

We will also take samples from the top, middle and bottom of your tank to determine the condition of your fuel system. We can then advise you on the best course of action in a detailed report.

In most cases, we’ll uplift your fuel and reimburse you for your contaminated supply before performing the full tank cleaning, then deliver a fresh batch straight into your newly restored tank. This is often the most cost-effective route to take.

What are the different tank cleaning methods?

There are two methods that we use to clean fuel tanks: man-entry and flush cleaning.

Man-entry (in-tank) cleaning

Man-entry cleaning, also known as in-tank cleaning and invasive cleaning, is the most effective method to clean a tank, however, it can only be used on tanks if the man lid is a minimum of 600mm.

This tank clean requires a minimum of three engineers; one inside the tank (2 engineers for large tanks), one at the man lid and another on the floor. This is a legal requirement by the HSE to ensure the safety of all parties involved.

Using a vacuum unit, our team suck out sludge matter and residue from the base and walls of the tank and then clean the surfaces at high pressure. Any waste removed during the tank clean is stored on our tanker, removed from your premises and disposed of at a licensed facility.

Non-man entry (flush) tank cleaning

When man-entry isn’t practical, if the tank is under 5,000 litres or if the man lid is too small for man-entry, we can flush the tank to remove sludge deposits safely and efficiently. Our team suck sediment and the contaminated fuel out using clean fuel and blow it, rotating the fuel around the bottom of the tank. This method isn’t as effective as man-entry cleaning but our team use their specialism and cutting-edge equipment to clean to their best endeavours.

Water jetting

This method uses high-pressure water jets to remove blockages and residue from both inside the tank and within the bund. This is a safe, quick and consistent method that is more environmentally friendly than other options which use solvents.
