The project involves the design of a prefabricated concrete structure with temporary buoyancy to redirect the drainage flow from Blackfriars to the new London collector known as the Thames Tideway Tunnel.

The main challenge of this project was to analyze the flotation, transportation, and mooring maneuver of the collector using the Orcaflex© program, taking into account adverse conditions of currents and tides, as well as the limited spaces between the river's boundary wall and the Blackfriars Bridge pillar. The operation of float out Involved moving the culvert to its final position between the bridge pillar and the river wall, passing through the gate of the cofferdam.

Location London, UK
