Tank & Bund Construction

The GBI-1853 features a double-skinned design, comprising an inner primary tank enclosed within an outer bunded tank. This configuration provides 110% containment of the total liquid being stored, ensuring compliance with environmental regulations and safeguarding against potential leaks.

The tank is constructed from heavy-duty structural plate steel to BS EN 10025-2:2004 S275JR, incorporates internal tank bracing (BST design), and is mounted on full-width bearers for maximum structural stability. The outer tank serves as a protective barrier, offering secondary containment in the unlikely event of inner tank failure.

Fuel Compatibility

This tank is suitable for the safe storage of a wide range of fuels including:

• White diesel (DERV)

• Red diesel (gas oil)

• Heating oil

• Hydrotreated Vegetable Oil (HVO)

Always check with your fuel supplier for compatibility if using additive blends or alternative fuels.

Compliance

All Atlantis Generator Bulk Tanks are built in accordance with BS799 Part 5 with required internal tank bracing. Each tank incorporates a bunded outer shell with a minimum 110% capacity, ensuring full compliance with environmental safety standards.

This 1,700 litre tank is manufactured to comply fully with:

• The Water Environment (Oil Storage) (Scotland) Regulations 2006

• The Control of Pollution (Oil Storage) (England) Regulations 2001
