Humber TBM honours ICE’s first female fellow

National Grid has announced that the tunnel boring machine (TBM) that is to drive a new gas pipe route below the River Humber has been named in honour of the Institution of Civil Engineer’s (ICE) first female fellow.

The name Mary was selected for the TBM by Paull Primary School pupil Kasey Doney, aged eight.

The 160m long, 510t TBM which is about to be launched at Goxhill has been christened Mary, after Mary Ferguson who became a fellow of the ICE in 1957.

Main contractors Porr, Skanska and A Hak will use the TBM to drive a 3.65m diameter, 5km long tunnel over the next year between Goxhill on the south side of the river to Paull on the northside.

Once completed a new 1m diameter gas pipe will be laid inside it to replace one that currently runs in a shallow trench in the river bed that is at risk of exposure and damage from tidal shift of sediment.
