Safety & Protection

Cathodic protection (CP) systems are fundamental to pipeline integrity management and are widely used on transmission and (high or intermediate pressure) distribution pipelines in the gas, petrochemical and water sectors. To comply with regulatory safety standards, routine measurements of CP levels are required.

Manual measurements, apart from their high cost, can only indicate problems after they have occurred, which can result in the pipeline being unprotected until the fault is discovered.

In the LIBRARY you will find a paper on the cathodic protection of pipelines for you to download - or view via the link below:-

It is not certifified if such a system is being employed on the South Wales LNG pipeline.  Whether it is, or not, your attention is drawn to the red text above.

Safety Demonstrations

In order to give a balanced views about the dangers of LNG, it has to be said that there are several videos on the YOUTUBE website that demonstrate how LNG fires can be delt with.   However, these are controlled events and the gas is NOT under pressure as would be in the case of the South Wales LNG pipeline - a pressure of 1,360 psi (94 BAR).

Below is an example of a controlled demonstration, one that it thought to pacify those who are worried about LNG fires - remember, there is no high pressure LNG in the video below:-

“For the sceptical, there is ample evidence of major LNG fire incidents—for instance, in the USA. As a result of their experience, no such plant is allowed in America within miles of residential homes. An American documentary film, 'The Risks and Dangers of LNG' by Tim Riley, covers many aspects of the dangers of LNG, including the history of accidents, the environmental impact, spills and vapour clouds, and the terrorist implications in relation to LNG tanks, tankers and pipelines.”
