60,000 Litre Refurbished HVO Fuel Tank Supply & Installation for the Rail Industry
The problem
The client was in need of a compliant bulk storage solution for refuelling locomotives with HVO. Following a competitive tendering process, initial returns for a new installation exceeded the available budget which prompted a commercial review.
Following this review, Crown Oil Environmental’s proposal to supply and install a refurbished 60,000-litre fuel tank was accepted, delivering significant cost savings whilst also meeting all operational and compliance requirements.


The client had requirements that any solution and installation must meet, including:
- Bulk storage with HVO compatibility
- Civil engineering works
- Regulatory compliance
- Minimal disruption during installation
- Value for money

Our solution
Crown Oil Environmental was able to work within these strict requirements to deliver:
- A fully refurbished 60,000-litre fuel tank – the tank underwent inspection, refurbishment and integrity testing before protective coatings were applied, bespoke pipework adaptations made and ancillary equipment installed
- Civil engineering works – these included surveys and excavation of the site, construction of a reinforced concrete base, drainage alterations and the installation of adequate ducting. With these works complete, we then completed the lifting operation to transport and install the tank, then reinstatement of the work site
- End-to-end project management – we coordinated every aspect of the works to reduce disruption, including arranging the design, procurement and refurbishment of the tank, contractor management, installation, commissioning and handover as a single point of responsibility, all in compliance with the Construction Design & Management regulations (CDM)
- Commercially beneficial outcome – the refurbished solution reduced capital expenditure, shortened lead times, lowered embodied carbon and delivered a fully operational, compliant HVO refuelling facility with minimal disruption to the work site
A long-term partnership
The successful completion of the works delivered not only a compliant bulk HVO fuel storage and dispensing solution, but fixed HVO supply and long-term tank maintenance agreements. This means that the client will receive lifecycle support and long-term supply continuity with Crown Oil Environmental.

Conclusion
This project demonstrates how Crown Oil Environmental’s commercial innovation and engineering expertise transformed an over-budget tender into a compliant, sustainable and cost-effective solution while creating a long-term mutually beneficial strategic partnership.
