Partnering with Enrogen Limited to Secure High-Integrity Critical Fuel Storage

Atlantis Tanks recently collaborated with specialist generator manufacturers Enrogen Limited, based at Pocklington Industrial Estate in York, to deliver a high-capacity, engineered fuel storage asset.

Specifically, we designed, manufactured, and supplied a bespoke 65,900 Litre Steel Bunded Oil/Diesel Tank from our flagship StoraFUEL range. Engineered to provide robust, fail-safe fuel reserves for critical standby power systems and large-scale diesel generators, this custom vessel incorporates advanced control integrations, complex socket architectures, and complete secondary fluid containment.

Industrial standby power systems require continuous, uncompromising fuel reliability to ensure uninterruptible operations during grid failures. To meet the exact technical requirements specified by Enrogen, Atlantis Tanks custom-built a heavy-duty steel bulk storage system fitted with specialized drop pipes, automated valve interfaces, integrated terminal box telemetry, and comprehensive environmental protection.

Engineering Specifications: 65,900L StoraFUEL System

Custom-engineered to deliver maximum fluid storage efficiency while adhering strictly to UK environmental mandates and industrial safety standards:

• Capacity Metrics: 66,218 Litres Nominal Capacity (67,916L Brimful / 65,967L Useable Capacity with Overfill Prevention Valve)
• Outer Dimensions: 6,200mm (L) x 3,500mm (W) x 3,500mm (H) (excluding bearers and fittings)
• Inner Dimensions: 5,810mm (L) x 3,370mm (W) x 3,495mm (H)
• Weight Profile: 8,407 KG (Estimated Dry Weight) / 64,098 KG (Estimated Wet Weight)
• Structural Material: High-grade steel engineered to BS EN 10025-2:2004 S275JR standards and compliant with BS799pt5, featuring comprehensive internal tank bracing for structural rigidity.
• Secondary Containment: Integrated outer bund providing 110% total fluid capacity, fully compliant with Control of Pollution (Oil Storage) Regulations, SEPA, and EA Guidelines.
• Surface Protection & Finish: ST2 surface preparation coated with Zinfos 340WS solvent-borne anti-corrosive primer and self-priming topcoat (150-micron wet / 75-micron dry film thickness) in Goose Grey.
• Handling & Maintenance Access: Full-width structural steel bearers, 4x heavy-duty lifting eyes (for empty transport), earthing bolt, and a 610mm Manway featuring a gasket, bolted lid, and lid handles for interior inspection.

Technical Socket Architecture, Automation & Piping Integration

Large bulk day/feed tanks demand sophisticated socket layouts and automated control interface points to streamline fuel transfer to standby generator engines. The unit features tailored top box and fill point fittings:

• Fill Assembly & Overfill Protection: Front-mounted 450mm deep lockable cabinet featuring a 2″ fill point with calmed inlet, lockable ball valve, non-return valve, drip cap, drip tray, and an Aluminum Overfill Limiter 2″. Includes a 3″ drop fill pipe arrangement for 2″ fill points.
• Suction & Removable Drop Tubes: Equipped with 2x 1″ removable drop tubes and a specialized 1.0″ x 3.5m Removable Flexible Drop Tube Assembly featuring a flexible suction line, foot valve, strainer, and T-piece for priming.
• Automated Valve & Telemetry Provisions:
  • Top box fitted with 1x DN100 PN10/16 flange for double-skin pipework entry.
  • 1x 1″ pump feed line fitted with an automated Belimo Valve wired directly to an integrated junction/terminal box.
  • 1x 1″ pump return line complete with a calmed inlet.
  • 1x drillable equipment mounting plate allowing custom gauge fitting on site.
• Integrated Sensing & Monitoring Infrastructure:
  • Fuel Level Sensor: 4-20mA fuel level sensor mounted and pre-wired to the central terminal box.
  • Bund Monitoring: Dual bund sensors (one located in the cabinet area and one in the main outer bund) wired to the central terminal box.
• Venting & Auxiliary Porting: 1x 2″ tank-to-bund vent, 1x 2″ bund-to-atmosphere vent, 2x 1″ spare tank sockets, 2x 1.5″ spare tank sockets, 1x 1.5″ bund sensor socket, and 1x 1.5″ front bund socket.

Technical Compliance and Turnkey Execution

Built in accordance with strict UK regulations—including the Control of Pollution (Oil Storage) (England) Regulations 2001 and Water Environment (Oil Storage) (Scotland) Regulations 2006—this installation guarantees environmental protection and compliance for critical infrastructure projects. This project highlights Atlantis Tanks’ capacity to deliver technical, heavily customized fuel systems for generator manufacturers and power resilience installations.
