Detail
G T Jones' team successfully completed a cable installation project at Carno Wind Farm, delivering essential infrastructure connection across predominantly moorland terrain. This project presented challenging ground conditions, including peat bogs and difficult terrain, requiring careful planning, coordination, specialist equipment and experienced site management to ensure the works were completed safely and efficiently.
The installation was carried out using our Foeck Plough and Winch machines, allowing the team to deliver an efficient cable installation solution suited to the demanding site conditions. Working alongside Jones Bros, the team delivered the installation to a high standard, completing all works within three weeks, including mobilisation and demobilisation.
Our works involved ploughing in 630mm² cables in trefoil formation alongside a 32mm fibre duct. Each circuit was installed within a full bed and surround of protective stone dust, at a total trench depth of 1,200mm to achieve the required minimum cover depth of 900mm. The installation was then completed with protective tape tiles and warning tape to provide additional protection and clear identification of the underground services. We installed two circuits, totalling 4,500m, making sure to maintain a 4m separation between the circuits, with an earthing cable installed along the full length of one of the circuits.
The G T Jones team utilised the Foeck Plough and Winch machines to support the installation across the moorland environment. The use of this specialist cable installation equipment helped streamline the operation, maintain consistent installation progress, and manage the logistical challenge associated with working across difficult terrain.
A Powersystems Engineer supervised the works throughout the installation, providing technical oversight and ensuring the project was delivered in accordance with the required standards. All installed cables were tested and successfully passed before the team demobilised from site, confirming that the installation met the required testing criteria.
We would like to thank the Jones Bros workforce for their cooperation and support throughout the project. Working alongside a team that demonstrated the same commitment, drive and dedication to delivering quality work made the project a positive and successful collaboration.
| Metric | Traditional Open Cut | Foeck Plough | Estimated Benefit |
|---|---|---|---|
| Programme | Approx. 45 days | 10 working days | 78% shorter |
| Excavated material | Approx. 4,275m³ | Minimal excavation | Substantial reduction |
| Construction fuel | Approx. 12,960L | 6,500L | 50% reduction |
| Workforce travel fuel | Approx. 1,023L | 227L | 78% reduction |
| Total fuel | Approx. 13,983L | 6,727L | 52% reduction |
| Fuel-related carbon emissions | Approx. 38.5tCO2e | 18.5tCO2e | Approx. 20tCO2e reduction |
The Foeck Plough and Winch allowed 4,500m of cable to be installed across moorland and peat bog with minimal excavation. Compared with traditional open cut, the programme was 78% shorter and total fuel use was halved, saving approximately 20 tonnes of CO2e.
