Inside the network access of a new gas substation
The UK's gas infrastructure is aging. The numbers tell the story:
ℹ️ The National Transmission System (NTS) for gas has a total length of 7600 km
ℹ️ The larger distribution network has a total length of 280,000 km, comprising approximately 12,000 km of high pressure pipes, 35,000 km of intermediate and medium pressure pipes and 233,000 km of low pressure pipes
ℹ️Construction of the NTS began in the 1960s, with the majority of the current network built over a 10-year period
ℹ️ Transmission pipes have an expected lifetime of 80 years - meaning the existing network is expected to become obsolete from around 2050
This ageing gas main infrastructure is necessitating essential upgrade works across the UK. In one recent project, Cubis Systems was selected to supply access chambers and covers for substation civils works - supporting safe installation, compliant reinstatement, and future operational access.
The challenge
As part of the upgrade works, it was necessary to construct an entirely new substation to support the local energy network. This new substation build presented typical utility project constraints:
- Need for solutions that could be installed rapidly and flexibly alongside ongoing civils activity
- Requirement for chambers and covers to pass strict load bearing tests, with verified strength vertically and on the side wall
- Long-term durability to support inspection and maintenance throughout the asset lifecycle
- Repeatable quality to meet the performance requirements of a critical energy asset
Against these requirements, it was Cubis Systems and our STAKKAbox™ range that made it into the specification.
The solution
We supplied a package of lightweight, modular access chambers and compatible covers to support the substation construction:
| STAKKAbox™ Modula: providing flexible build depths and configurations to suit site conditions
| Composite access covers: high-performance but lightweight covers capable of meeting site loading requirements
The STAKKAbox™ chambers were installed on-site within the day - allowing the contractor to establish secure underground access points quickly and keep the project moving. All while maintaining consistent, repeatable build quality.
Key benefits of the installation include:
✔ Faster handling and installation on site thanks to lightweight, modular components
✔ Improved safety due to reduced manual handling and simplified on-site assembly
✔ A future-ready access arrangement designed to support ongoing inspection and maintenance of substation services
✔ Improved sustainability outcomes due to the reduction of concrete and plant
"Using STAKKAbox™ has helped speed up the programme - it's the go-to chamber we install. Much less messy on-site, too." Site Engineer
