Learn more about the requirements for HSE tiers, and how these are allocated.
If required, suppliers and contractors are allocated a tier. This is determined through
- the registration process (for new suppliers and contractors), or
- the HSE requalification process (for existing suppliers and contractors).
When suppliers or contractors are assessed, they may be asked to submit a HSE management plan. The HSE management plan, together with any additional information, will be assessed accordingly. If successful, a tier will be allocated.
To learn more about our selection criteria read our tier grading and selection document.
