Millennium Way, Greenwich

In 2021, Flowstop Services undertook a 42" stopple operation at the old Greenwich Holder Station, opposite the O2 in london. This was the first operation of its kind in the UK and along with SGN and JDT, the main contractors, the operation was a great success. 

Using a 42" plugging machine Flowstop Services were able to plug the main and carry out cold cuts as required.

The video below shows how the stopple enters and opens up inside the main.
