It was the biggest pipeline project since the early 90s - the Trans-Lincolnshire line from Immingham to Peterborough is longer - but it's quite conventional in construction and come to that, it is a duplication of the existing route, not a completely new route at all, whatever the local press may have printed at the time.
There were some wondrous things to be seen over planning permission for 'barn conversions' ... I used to go out and establish the lines, define heavywall pipe or minor variations in the alignment 'according', and there were 'conversions' which were barely visible as grassed-over foundations in places.
the main problems tend to revolve around locals who tend to expect 'oil rig' wages for local work practices, which they are almost invariably disappointed in.
