The Frogmore Fullround System successfully passed the tests on the 3rd September.
Frogmore Connection tunnel is part of the Tideway project.
It was installed a mock-up with jobsite segments in order to carry out a full scale trial an simulate a complete cycle.
Site program required a high production rate for the two tunnels, 500m and 600m long.
The No.4 fullround shutters are designed to work with the hit / miss methodology.
Given the tight tolerances and the small dimension of the tunnel, the Engineering invested a huge amount of hours to develop a bespoke and innovative solution to comply with the requirements.
A complete process simulation and risk assessment have been part of the complex development.
