10-point checklist for oil tank inspections

Inspections are absolutely essential for anyone with an oil tank. They help detect any issues early on, saving money on potential replacements and spillage clean-up. Oil tanks should be inspected regularly to prevent problems from building up or going undiscovered.

This blog will take a look at the top 10 things inspectors look or during an inspection, as well as answering some of the most frequently asked questions surrounding oil tank inspections.  

1. Tank Location and Stability

Your oil tank will be examined to ensure it is installed on a solid, level surface capable of supporting its weight, looking for any signs of shifting, tilting, or instability, such as cracks, erosion, or soft spots in the foundation. 

1. Pipes and Connections

All pipes and connections, including fill and vent pipes, will be carefully examined to make sure they are secure and for any signs of wear, rust, or damage which could compromise the integrity of the system and potentially lead to leaks. Special attention will be given to areas prone to deterioration, ensuring that all connections remain secure and in good condition to prevent any future issues.

1. Vents

The vent pipe will be checked to ensure it is clear and free from any blockages. Your Oil Tank Technician will also verify that the vent whistle, which serves as an important indicator during refuelling by signalling when the tank is nearing full, is functioning properly. 

1. Tank Legs and Supports

Tank legs and supports will be thoroughly examined for stability and any signs of rust or corrosion. Assessing whether the supports are strong and intact, is important as weak or damaged supports can compromise the tank’s structural integrity and potentially lead to tank failure. 

1. Oil Level Gauge

The oil level gauge provides accurate readings of the oil level. Your OFTEC technician will ensure that the gauge is not sticking or malfunctioning, as inaccurate readings could result in unexpected empty tanks, leading to heating system interruptions or shutdowns. Oil tank gauges are also handy for detecting potential oil theft, so having an effective one is important.

1. Tank Certification

During your inspection, the oil tank’s certification will be verified to ensure it complies with local regulations and industry standards, as well as reviewing documentation of previous inspections and maintenance. This helps confirm the tank’s safety and compliance with regulatory requirements and any missing or expired certifications will be flagged up, so you can take action.

1. Surrounding Area

The area around the tank will be evaluated for potential hazards such as vegetation overgrowth, debris, or water pooling, all of which can accelerate corrosion or cause safety concerns. Make sure your technician checks that the tank remains accessible for routine maintenance and refuelling, noting any obstructions that could affect these processes. 

1. Signs of Leakage

The technician will look for any indications of oil leakage, such as oil stains, wet spots, or discolouration around the tank, as well as near the fill and vent pipes. The ground beneath the tank will also be carefully examined for any signs of oil seepage or pooling. These signs will help identify potential leaks that could lead to environmental damage or tank failure if left unaddressed.

1. Exterior Body Condition

The exterior of the tank should be closely examined for signs of corrosion, rust, or physical damage, depending on the tank material (steel, or plastic). Steel tanks are particularly vulnerable to rust, which can weaken the structure and eventually lead to leaks, so extra attention will be spent looking for this. With plastic tanks, stretches, bulges and discolouration from the sun are common, as well as splits or cracks. Any deterioration or damage found on the tank’s surface will be highlighted as a potential risk to its integrity and longevity.

1. The Bund 

The bund of the tank will be checked to ensure it is functioning properly. Its purpose is to contain any oil that leaks out of the main oil tank, preventing spills. It will be inspected to verify that it is operational and in good condition and to ensure that any collected oil is emptied.

FAQs:

1. Why is having regular oil tank inspections so important?

• Oil tank inspections are crucial to identifying issues or potential issues early on. Inspections can save you a lot of money in the long run, and could even save you costly fines that occur with leakages and spillages.

1. How often should my oil tank be inspected?

• You should get your domestic oil tank services at least once a year, but some suppliers recommend every six months to be extra safe and ensure that your oil tank is operating at maximum integrity.

1. What is the outcome of an oil tank inspection?

• At the end of your oil tank inspection, you will receive a complete summary. This will outline any issues the technician might have come across, and any next steps they feel you should take. It is important to hold onto these documents as they can help you out in case of an oil tank emergency (link)

1. Can I do an oil tank inspection myself?

• No, you cannot officially perform an oil tank inspection yourself, as this must be carried out by a registered ‘competent’ person, according to the UK government’s competent person scheme. However, you can practice good maintenance in between inspections by checking your oil tank for cosmetic damage and signs of spillages and by monitoring the oil levels through a gauge. 

1. What is the oil tank inspection process?

• First, a technician will take a look at the area your oil tank is in, checking the frown and surrounding areas for signs of leakages or spills. 
• Next, they will carry out an external inspection for any cosmetic damage such as bulging, splits, cracks, stretches, rusting, corrosion or discolouration. 
• Your technician will then check the pipelines, connections, valves and filters, to ensure your tank is running smoothly.
• Once this check is complete, and inspection of the interior will be carried out to check the oil levels, signs of condensation or other types of contamination.
• To complete your inspection, your qualified technician will complete paperwork, to ensure proof that your oil tank has passed its inspection, and any recommended maintenance that you should carry out.
