Lochaber Pipeline Feasibility Study

A high-level pipeline routing study for 3 options to provide natural gas at 7 bar to the Lochaber area in Scotland, from 3 possible supply points. (Over 100km of main laying pipe).

The project involved:

• Feasibility and routing for the 3 options for the pipeline
• Geological and Ecological studies
• Cost Estimates
• Flood risk assessments

Saith was tasked with producing a feasibility report, cost estimate, routing plans, geological & ecological reports and flood risk assessments.

The routes were mapped and a desk study was used to identify points of difficulty – such as crossings and diversions from the main highways. These were plotted on to routing sheets using OS mapping as a background.

Site surveys were then conducted for the possible routes to verify the more challenging areas, crossings etc. that were on the routes, and find alternatives where necessary.
Saith then produced the cost estimates based on distances from the model and data from the reports and crossing schedules. The underlying geology was factored into the data as well as the ecological considerations.
