This document specifies requirements for underground pipework systems used to transfer liquid fuels and their vapours at petrol filling stations. Minimum performance requirements covering fitness for purpose, safety and environmental protection are given. This document is applicable to pipework made from thermoplastics, which can include some degree of reinforcement, and to flexible metal pipework. It does not apply to fibre reinforced thermosets, commonly referred to as glass fibre reinforced plastic (GRP), nor to rigid metals. This document is applicable to: - delivery pipes from tanks to dispensers, including positive pressure, vacuum suction and siphon modes; - fill pipes from road tankers to tanks; - vapour recovery and vent pipework; - pipework for secondary containment; - fittings. It does not apply to pipework for use with liquefied petroleum gas.

This document specifies the functional requirements and principles for design, operation and requalification of pipelines in the petroleum and natural gas industries using reliability-based limit state methods as permitted by ISO 13623. Reliability-based limit state methods provide a systematic way to predict pipeline safety in design and operation. This document supplements ISO 13623 and can be used in cases where ISO 13623 does not provide specific guidance and where limit states methods can be applied, such as, but not limited to, — qualification of new concepts, e.g. when new technology is applied or for design scenarios where industry experience is limited, — re-qualification of the pipeline due to a changed design basis, such as service-life extension or change of the transported fluid, which can include reduced or increased uncertainties due to improved integrity monitoring and operational experience or limited information on pipeline properties relevant to the new service — collapse under external pressure in deep water, — extreme loads, such as seismic loads (e.g. at a fault crossing), ice loads (e.g. by impact from ice keels), — situations where strain-based criteria can be appropriate. This document applies to rigid metallic pipelines on-land and offshore used in oil and gas industries including lower carbon energy.
