Pipeline Case StudySouthern Gas Networks (SGN) have commissioned RSK Orbital to record their new-build pipeline construction over the past seven years. The initial applications of the ViSiVi surveys were for route selection.
We become involved when primary and alternative routes have been selected from a desktop exercise. We fly these routes in order to identify any key constraints without any of the team having to set-foot on third party land, thus providing a subtle yet comprehensive view for all. Once the final route has been selected the ViSiVi data is used for EIA (Environmental Impact Assessment) and Stakeholder Engagement.
ViSiVi is used during the build phase by both engineers, environmentalists and has also been used for the archeaological teams to help identify potentially significant sites.
SGN were the first of our clients to film the pipeline projects during construction, providing very valuable evidence of the effect of the build on the surrounding environment and evidence of the compact construction techniques utilised. Of course, this information is useful for management, to demonstrate in future projects how work is undertaken and as information to counter spurious post-construction compensation claims.
As ViSiVi has helped in routing, engineering, environmental issues, engagement amongst other disciplines, SGN decided to film all of their projects approximately a year after reinstatement is complete. This final set of images completes the picture of the build. The post reinstatement photography is perfect to compare with pre-construction. This demonstrates the build's success and can also provide evidence to counter certain landowner claims. It is always satisfying to see how modern pipeline reinstatement techniques result in such little impact on the visual environment; such is the case with the SGN pipelines over the last seven years.
