Oil Tank Decommissioning
Many years ago it was the norm for larger properties, schools, commercial buildings to have a steel heating oil tank installed within the basement of the building. The tank would have been filled via a 2″ fill point on the outside of building. Now 40-50 years later with many forms of energy available the tank and associated pipe work in the basement is made redundant and needs to be safely removed from the building.

COTS can safely and efficiently decommission (remove) any oil tank that has reached the end of it’s life. We use our own fully trained and OFTEC accredited engineers to carry out this work for you.

Our service is available to both domestic and commercial customers, so whether you have a huge industrial tank or a small tank serving your home, we have the resources and skills to carry out a safe and efficient removal. All materials will be disposed of safely in accordance with current legislation and industry best practice.

We will be pleased to arrange for a visit and provide you with a formal quotation to carry out the work required.

A Typical Oil Tank Changeover

Many people moving to areas on oil, especially those relocating to the country from towns and cities, have never seen an oil tank before. Here is an overview of a commonly used oil tank and a summary of a typical oil tank changeover

Once you have decided that you need to have your oil tank changed we will arrange to come and complete a site visit. During this we will assess the tank, location and your needs, and will carry out a comprehensive risk assessment CD10 form to determine the type of tank you need. We will discuss all of the options available to you and aim to have your quote with you within 24 hours of our visit.

Now the job has been booked in, at a time convenient for you, and we are on our way to complete your oil tank changeover.

When we first arrive on site we carry out a quick assessment, to ensure that the conditions, etc, are still suitable, and then check the pipework currently in place. We prefer you to have fuel in your old tank (at least 500 litres) as this ensures we can bleed through the pipework to the boiler and it allows us to check the connections. If you run the oil tank right down, sludge might be drawn into the pipework and pump on the boiler, and may result in costly repair bills.

If the pipework is clear we can then get started. We start by switching off the oil supply, and then pumping out the oil from your tank. Dirt naturally builds up in oil tanks over time so we separate the clean oil, putting this into an IBC (an Intermediate Bulk Container) and then put the dirty oil into another container to be taken away and disposed of through the correct channels.

Once the tank is empty we disconnect the pipework and remove the tank using our specialist equipment, which usually includes one of our cranes, Ensuring that the base is still intact and complies with current standards, we then move/lift your new tank into place. Once this is secure we reconnect the pipework, pump the clean oil into your new tank. We then will bleed the new pipework through to the existing connection and fire up your boiler/AGA etc, eave the site tidy. For a 1365 ltr tank, in ideal weather conditions, this will take approximately 3-4 hours. Upon Completion of the works a T1/133D form will be sent along with an OFTEC installation certificate.

All of work is guaranteed and our bunded tanks come with various long Guarantees.

Top Tips

Make sure you know how to isolate the tank’s oil supply in order to quickly shut off the oil flow in the event of a problem. You will usually spot the isolation valve near the tank’s outlet.

Check your tank and its surrounding area for dead grass or plants, sodden ground and other signs of a leak. If there are signs of this, you may have a leak which needs to be dealt with immediately. Call COTS for action.

Restrict access to getting anywhere near the tank by locking all gates and having bushes around the boundary of your land, and have some form of additional gate around your oil tank making sure make sure you are leaving the recommended distance of 600mm.

If you aren’t present when your fuel is delivered make sure that you disable all security devices and leave access points unlocked so that the supplier can refill your tank.
Enable them and lock them back up after the delivery has taken place!

If you have an AGA or Rayburn check with your AGA supplier if you need an additive to help the oil burn!

It is a good idea to order about ¾ of your tank’s capacity to allow for any remaining stock of oil in your tank. Alternatively, Ackerman & Niece offer a “top up service” which means they will fill you tank at appropriate times to prevent you running out.

It is important that you don’t ever ignore any advice from your fuel supplier on the condition of the tank or the access; as if the issue isn’t resolved they may refuse to deliver. Call COTS for a tank inspection ASAP, we will do all we can to help.

Oil spill kits including sorbent granules, spill pads, drains blockers and leak sealing putty are readily available from most industrial supply companies and online. Your local fuel distributor may also sell them.

Do not put your heating on for any periods longer than necessary by using the timer system on your boiler/burner. Also, make sure you keep building doors closed where possible to prevent heat escaping.
