Battersea gas tunnel breakthrough achieved

Gas infrastructure operator Cadent has announced that tunnelling work for a new gas tunnel below the river Thames has been completed.

The tunnel boring machine (TBM) – named Amanda – has successfully broken through into the 30m deep reception shaft in Battersea Park.

Work on the new tunnel is being undertaken by Triio, which is a joint venture of Skanska, Barhale and Mott MacDonald.

The remote controlled TBM that drove the 330m long tunnel was launched from the grounds of the Royal Hospital in Chelsea last month.

Cadent project manager Andrew Hejdner said: “The end of tunnelling marks another major landmark for the team and our focus will now shift to installing the new gas pipe.

“We’ve got some tremendous expertise on-board this project and our progress to date is testament to that.

“The tunnel is a key part of Cadent’s essential £1bn programme to replace ageing gas infrastructure in the capital.

“Our work help ensure London continues to have the infrastructure it needs to thrive as one of the world’s leading cities.”

Cadent has said that the project team will now start preparing the tunnel for the installation of the new gas pipe which will help keep the burgeoning area – which includes the Battersea Power Station and Nine Elms development – connected to safe and reliable gas supplies.
