These regulations aim to ensure the safe design, construction, and operation of pipelines. Through ensuring pipeline integrity and safety, environmental risks are also minimized.
Regulation 6 requires operators to ensure that no fluid (including natural gas) is conveyed in a pipeline unless it has been provided with safety systems that will reasonably protect people from risk to health or safety. Safety systems include emergency shut-down valves and shut-off valves, devices that prevent safe operating limits from being exceeded, and leak detection systems. Safety systems also include control or monitoring equipment, such as flow detectors and pressure monitors.
Regulation 13 requires operators to ensure that a pipeline is maintained in an efficient state and working properly. Maintenance and inspection requirements will vary depending on its material of construction, location, and fluid conveyed. For example, low pressure gas distribution and service pipelines onshore require monitoring, whereas pipelines that present major accident hazards need a safety management system. Pipelines that are out of service should also be maintained in a safe conditions.
