Torcross Rock Armour Depends on an Offshore Transfer Chain

Large barges feed two tidal beach shuttles

The Environment Agency's 14 October Torcross update describes a GBP 19.8 million scheme delivered by Kier on a design-and-build basis. FAQ 6 identifies 1-3 t and 6-10 t armour grades from Norway, Scotland and Northern Ireland. Large barges will anchor offshore and transfer stone to two smaller side-loader barges for delivery around high tide. The plan sends 58,000 tonnes by sea and 30,000 tonnes of smaller filter material by road. Rock shipments are programmed from mid-October to early December, with installation extending to April 2027 [1-2].

Filter supply and landing space set the workfront

The two delivery routes meet at the revetment. A fast offshore shipment can create a stockpile that the beach operation must sort and place; a late filter delivery can leave the next armour section waiting. The contractor therefore needs a rolling plan linking offshore inventory, shuttle availability, usable tidal landings and the sequence of filter and armour placement. Working area, excavator reach and room for grade separation determine how much delivered stone can become completed defence during each window.
