Extra High Voltage Underground Cable Installation
Procter and Street has extensive experience in planning and managing projects within the high voltage and extra high voltage cables sector (220kV and 400kV). These cables often originate from offshore windfarms and terminate at new converter stations and are usually undertaken through a Development Consent Order, meaning landowner agreements and conforming to the DCO are an important part of a successful delivery.
We can offer a variety of expertise in relation to the export of underground EHV transmission cables, including:
- Implementing a strategy to conform with the Development Consent Order stipulations
- Setting up Quality Control Systems in line with Client demands and ultimately OFTO requirements
- Procurement of key materials and temporary works within specification
- Setting clear communication strategy with stakeholders and within DCO constraints
- Package managing the Horizontal Directional Drill and the interface between open trench and HDD
- Developing plan for cable pulling and fibre installation off drums between joint bays
Hornsea 2 Offshore Windfarm
P&S staff member, Jack Procter, was an integral part of the successful delivery of the Hornsea 2 Cable Export which included 3 circuits of 220kV crossing 37km of East Lincolnshire and 21 separate joint bays. The project had multiple challenges from complex temporary works, varying HDD crossings including major rivers and railways and sensitive environmental and ecological constraints.
