The Friars’ Bay Long Sea Outfall (Brighton Outfall) is part of the £300 million environmental improvement scheme to bring cleaner seas to Sussex.
The subcontract was awarded to a joint venture between Westminster Dredging and Land & Marine for the assembling and installation of the outfall pipeline. Westminster Dredging carried out the dredging of the trench and Tunnel Boring Machine (TBM) reception pit, assisted in the towing, aligning and placement of the pipeline in the trench and backfilled the pipe trench after pipe installation. In addition Westminster Dredging supplied and transported the 60-300kg rock for placement as protection to the top of the diffuser domes and assisted with the recovery of the TBM from its reception pit and its transport back to shore. Westminster Dredging also provided its in-house hydrographic surveyors and equipment to the Joint Venture.
