Chelsea to Battersea Tunnel and Gas Pipeline

Barhale carried out work on the new Chelsea to Battersea gas pipeline. As part of the ongoing work to replace and upgrade large diameter gas mains throughout central London, a new gas pipeline was required underneath the River Thames between the Royal Hospital Chelsea and Battersea Park.

The overall project was split in to two separate contracts, both of which were awarded to Barhale:

Contract 1: Construction of two shafts, connected via a new tunnel
underneath the River Thames, which would facilitate the installation
of the new 600mm diameter gas main. This contract was delivered to
tRIIO.

Contract 2: Installation of the 600mm diameter, welded steel pipeline
through the tunnel. Including the installation of several governors
and the connection of the new pipeline into the existing network. This
contract was delivered directly to Cadent Gas Ltd.
