Oil and gas industries including lower carbon energy — The effects of High Voltage DC interference to buried pipelines — Measures to be implemented ISO/AWI 24695

Scope

This document describes technical measures to be carried out at crossings and parallelisms of buried
metal pipelines influenced by HVDC systems.
It provides guidance on how the design, construction, operation, maintenance, and decommissioning
phases of HVDC systems affect buried metal pipelines.
Electrical interference conditions (AC and DC) to pipeline systems are described, and acceptable levels
of interference are discussed.
Minimum separation distances are recommended.
The following aspects are not covered in this document:
-Contractual responsibilities
-Personnel safety
