Safety Standards
API 653, EEMUA 159, IEC 61511 and ISGOTT underpin our inspection, integrity and operating standards.
Built on recognised industry standards
Good safety performance rests on good standards. Our inspection, integrity and operating practices are built on recognised industry standards that are widely used and well understood across the energy storage sector.
Recognised industry standards — API 653, EEMUA 159, IEC 61511 and ISGOTT — underpin our inspection, integrity and operating practices. A rolling inspection program keeps tank integrity and safety systems verified and documented year over year.
Using established standards means our practices are benchmarkable, auditable and aligned with what regulators, customers and partners expect to see at a well-run terminal.
Key capabilities

Rolling Inspections
Tank integrity and safety systems verified year over year.
A recognised framework
Our practices draw on standards that are widely used across the energy storage sector.
- API 653 — tank inspection, repair, alteration and reconstruction
- EEMUA 159 — above-ground vertical storage tank integrity
- IEC 61511 — functional safety of process instrumented systems
- ISGOTT — international safety guide for oil and gas tanker operations
- ISO 9001 / 14001 / 45001 — quality, environmental and OH&S management
A rolling inspection program
Standards are only useful if they are applied. We apply them through a rolling inspection program.
Tank integrity and safety systems are inspected on a defined schedule, with findings tracked to closure and lessons fed back into asset care. The result is assets that stay sound and safety systems that work when they are needed.
Frequently asked questions
What are API 653 and EEMUA 159?
They are recognised standards for the inspection and integrity management of above-ground storage tanks — API 653 covers inspection, repair, alteration and reconstruction; EEMUA 159 covers tank integrity management.
What is IEC 61511?
It is the recognised standard for the functional safety of instrumented protective systems in the process industries, defining how safety integrity levels are designed, verified and maintained.
What is ISGOTT?
ISGOTT — the International Safety Guide for Oil Tankers and Terminals — is a widely used guide for safe operations involving oil tankers and terminals, covering marine transfer operations.
