Following a tidal surge in December 2013 widespread disruption was created along the east coast. The surge entered the Humber and associated rivers and channels including the Dutch River so concerns were raised about flood risks. A permanent flood defence using a combination of sheet piling and rock armour was constructed to mitigate the risk.
The £45million scheme is one of the largest river flood defence schemes in the country. A variety of long reach machines were required over
a 16-month period for multiple works on the scheme.
Working on the Greenport development in Hull, the CAT 385 long reach excavator fitted with rock grab and GPS dig control system is placing rock armour.
Protecting the coastline in Guernsey required the placement of over 10,000 tonnes of rock armour ranging from 1 to 3 tonnes in size.
