Home> STORAGE> PIPELINE>

A five-mile pipeline would be needed to link the well site at Albury to the proposed gas processing facility in the parish of Ripley. From there, a further one-mile pipeline would provide a link to the regional gas grid and so allow gas injection into the Albury store and subsequent return in times of need. The pipelines would be installed during a six-month period between April and October and the land would be restored during the same year

Route

The area through which the pipelines would need to pass would be through land used principally for agricultural activities and livestock grazing. Approximately 75per cent of the pipeline route would need to cross land which is in agricultural use (Grades 3 and 4).

Construction

The pipeline would be buried to a minimum depth of a metre throughout its length. Standard open cut construction techniques would be used, except where the route crosses roads, railways and the Tilling Bourne watercourse, where it would be bored underground.

Construction would take place within a designated area, referred to as the ‘working width’, of about 26 metres. This width would be restricted in areas through mature trees and hedgerows, to a maximum of 15 metres. All boundaries of the working width and all accesses to the site would be temporarily fenced for the duration of the works.

The maximum area of land affected by the pipeline installation would be about 24.5 hectares. The temporary piles of spoil which would be generated are estimated at a maximum of two metres high.

The contractor installing the pipelines will require a temporary construction yard in which to temporarily store the lengths of pipe. This pipe store would be required for about six months and is planned to be just south of East Clandon. The site layout is shown in the diagram on the left (click on it to enlarge).

Above-ground installation

The proposed above-ground installation near Ripley would comprise a minimum offtake facility located adjacent to or within the existing Scotia Gas Networks site. The land-take required is estimated to be no greater than 0.16 hectares (40 metres x 40 metres). The plant would include some above-ground pipework with valves, a small instrumentation kiosk and lighting, which is only required for emergency maintenance work. Once operational, the above-ground installation would not normally be manned. The location is shown on the project plan.
