Case Studies

Below is a list of case studies for you to browse through. They each outline the project’s goals and results.

Centrica Power Station

Case Study 1

Six full tanker loads per day each transferred 30,000 litres of oil from a site in Peterborough, UK, over an 18 week period, totalling 800 journeys. Finally shipping out a whopping 23 million litres of oil from Centrica’s power station.

The following video shows details for the Centrica Power Station case study.

The colossal operation to remove £11 million worth of unused fuel from Centrica Energy’s power station in Peterborough was an even bigger success.

Storing a volume of oil to this extent on a site like Centrica’s was proving a costly backup plan. After weighing up the pros and cons, they decided it would be cheaper for them to offload their fuel onto us as the costs to keep it on-site were rising.

Why Remove Fuel From A Site?

Storing 23 million litres of oil can pose various health and safety threats to the environment and employees, so businesses have to follow strict, and costly, guidelines or risk facing heavy fines and backlash. As a responsible company, Centrica Energy called upon Crown to assess their fuel, propose our solution and help them comply with current legislation to help reduce their costs.Paper cut out - Crown Oil Environmental at Centrica Power Station

With the storage of fuel being on-site, it requires employee training for risks and safety that is an additional cost some companies don’t view as viable. For Centrica, it was much more economical to sell the oil to us than keep it for backup purposes. Not only is it an extra cost when training staff on the compliance of fuel storage but, tank integrity, which plays a large part in today’s fuel storage responsibilities, is another cost and responsibility added on top.

When you look at the whole cost of buying and storing fuel then include training, accreditations and ongoing maintenance and checks, the costs can just creep up and up until they no longer prove worth it.

The additional possibility of the fuel being in a poor condition forced Centrica to think about the financial benefits of removing it.

The Good Oiled Days

The massive stocks of oil at the site were surprising however, some of it has been stored there for ten years and was originally kept to hedge against sharp spikes in gas prices. The decision to get rid of it became concrete once they’d calculated the uneconomical extra cost of money and time ensuring its safety and the eventual relief of their COMAH status(Control of Major Accident Hazards). The fuel itself could require cleaning or may be damaged beyond use after such a long time in storage, so the one-off cost of removal was the best option.

The shipment of oil will go through a fuel testing and analysis phase where the oil that requires treating will be polished and treated further, if required, and then delivered and used to heat homes across the UK. This not only ensures that the fuel is recycled and not wasted through damage but, it helps keep British families warm and happy through their central heating oil.

Lock ‘n’ Load

Taking on a job of this scale was no small feat but after investing heavily in a skid facility, we were able to transfer the fuel from the site to each tanker in just 20 minutes. Additional safety features mean that not only can we do each transfer quickly but, features such as overfill protection help prevent any spills from occurring.

Although the transportation of the fuel was done by road, the removal of another 5 million litres of oil was being considered to go by sea. The idea behind this was to reduce the amount of tankers on the road. It would see the oil returned to where it came from originally via a pipeline from the nearby Barrow Dock. Further health and safety checks had to be done to ship the last 5 million litres of fuel by sea to guarantee its viability.
