Reducing Environmental Risks: Self-Bunded Tanks in Australian Oil & Gas Operations

October 06, 2025

Fusion-Weld Engineering provides self-bunded tanks in Australia, ensuring safe, compliant and sustainable fuel storage for oil and gas operations.

Environmental safety remains a priority in the Australian oil and gas sector, particularly when handling and storing fuel. Traditional storage tanks pose risks of leaks, ground contamination, and costly clean-ups. To address these concerns, self-bunded tanks have emerged as a sustainable solution that supports both operational efficiency and compliance with environmental regulations.

The Environmental Risks in Oil & Gas Operations

Fuel storage and transfer carry inherent risks for operators. A small leak can escalate into significant soil contamination, while unmanaged spills may lead to groundwater pollution. These issues not only harm ecosystems but also create costly remediation obligations.

Australian oil and gas companies face strict regulatory oversight. Authorities demand responsible storage and handling practices, and non-compliance can result in fines, reputational damage, or even shutdowns. This makes adopting safer, more compliant storage technologies a strategic requirement for modern operators.

What Are Self-Bunded Tanks?

Self-bunded tanks are engineered with a double-wall containment system that acts as a built-in spill barrier. Unlike conventional tanks that rely on external bunding, these units integrate the protective layer, offering an immediate safeguard against leaks.

By containing potential spills within their secondary wall, they minimise the risk of fuel escaping into surrounding soil and waterways. Compared to standard tanks, self-bunded models provide a higher level of security and reliability for long-term operations.

Operational Gains from Innovative Fuel Storage Technology

Companies across the oil and gas sector are increasingly adopting double-walled fuel tanks due to their multi-dimensional advantages. These storage systems support safety, compliance, and efficiency in one design:

•  Spill Prevention: The integrated double-wall system provides an extra layer of protection against leaks.

•  Regulatory Compliance: Designed to meet stringent Australian environmental standards with reduced risk of breaches.

•  Cost Efficiency: Lower clean-up costs and long-term maintenance savings when compared to conventional systems.

•  Mobility & Flexibility: Ideal for remote or temporary project sites where transportable storage is necessary.

Compliance with Australian Standards

The Australian Standard AS1940 outlines strict requirements for the storage and handling of flammable and combustible liquids. For oil and gas operators, achieving compliance is not optional but an operational necessity. Self-bunded tanks simplify this process by incorporating features that align with the standards, reducing administrative and technical burdens on operators.

Meeting compliance does more than mitigate risks. Companies that invest in high-quality bunded fuel storage strengthen their reputation, enhance community trust, and secure long-term operational approval. The financial benefits are also significant, as avoiding environmental penalties or site remediation translates into measurable savings.
