Working with the National Grid – Modes of Transport
Leading Edge Only is working with National Grid, who are looking for innovative solutions for a suitable mode of transport in a 3m diameter high voltage cable tunnel.
In Spring 2020 National Grid embarked upon a seven-year, £1 billion project, to rewire South London via deep underground tunnels. This vital work will help keep Londoners connected to safe and reliable electricity supplies.
In total, 32.5km of 3m diameter tunnels are being constructed deep below the road network between Wimbledon and Crayford, which will carry high-voltage electricity cables.
The vehicle must have the ability to:
- Support 1-2 operatives (weight capacity of up to 150kg) in escaping from a tunnel environment in the instance of a fire or in the instance a member of the working party becomes injured.
- Will need to have lifting points
- Transport these 1-2 operatives through the tunnel lengths, of up to 14.4km, in order to perform operation and maintenance activities, at a max speed of 14km/hr
- Is to have sufficient storage space for a first aid kit, defibrillator and lightweight tools up to 50kg (up to 800mm storage width)
- Needs to be able to tow an attached stretcher/trailer that would support the evacuation of a casualty in the event of an emergency
- Access to a hatch opening
The use of dual batteries is encouraged to aid escape and to eliminate alternative solutions which may emit gases (harmful to health) in the tunnel environment.
The solution is limited to an electric option as the tunnels are considered as an enclosed space. 240v charging points are available at the bottom of each shaft.
What’s in it for you?
A successful collaboration could mean, for individuals, becoming part of the wider National Grid group, while for organisations, forming a potential partnership with one of the world’s most iconic brands to co-develop and co-launch the idea to market.
