New Standard will make it easier for engineers to understand buried pipelines
The new standard BS 9295, 'Guide to the structural design of buried pipelines', should help reduce costly and potentially dangerous failures.
The standard was published last month to address difficulties in following the National Annex BS EN 1295-1 document.
Because of those difficulties, "this means that it is possible to design pipelines in accordance with the National Annex, meeting all the required criteria but without engineers fully understanding the principles behind the design", said Sandra Rolfe-Dickinson, who helped write the new standard and who is pipeline expert at consultants MWH.
"This is dangerous, as the implications of any changes made to the design, either in the office or on site, are not understood or appreciated, and this lack of understanding can lead to costly failures."
She said BS 9295, in its role as a guide to BS EN 1295-1, explains and illuminates in simple terms the equations and concepts within the UK National Annex. It leads an engineer through the process of "rigid", "semi-rigid" and "flexible" pipeline design in an easy to understand and well thought-out way.
