You can find our most updated marine aggregates reports, regional dredging area charts, maps, and GIS datasets in the "Document downloads" window. As part of this, we also provide consent for the disposal of dredged sediment at sea and the use of dredged material, within the 12 nautical mile limit. This includes projects like Liverpool2 and London Gateway, where millions of cubic metres of marine sand and gravel have been dredged to create new deep-water port terminals. We licence capital and maintenance dredging projects which enable navigational channels to be created and maintained on the UK seabed, such as to enable ships to move safely in and out of coastal ports. These minerals are used in the production of fertilisers and the maintenance of roads as well as by the chemical and pharmaceutical industries. The Crown Estate has interests in evaporite minerals, such as salt, potash and polyhalite, occurring beneath the seabed and issues leases for extraction. The Crown Estate continues to work with British Marine Aggregate Producers Association and the aggregates industry to help support the effective and sustainable management of our seabed, helping to drive a significant long-term reduction in the total area of seabed licensed for marine aggregate extraction.Īs part of our management of marine sand and gravel extraction, we employ an Electronic Monitoring System to record dredging vessel activities associated with our mineral assets, helping to capture and assess dredging intensity, and ensure that all vessels remain within their allocated licensed area.
See here for more information about this tender process. The Crown Estate manages regular marine aggregates tender rounds.
Marine sand and gravel are also used in beach replenishment schemes, where they help provide coastal protection and enhance amenity value, and to act as infill for land reclamation projects. We provide licenses for the extraction of marine sand and gravel resources from the seabed, providing an important source of quality aggregate for construction and civil engineering projects, particularly in the South East of England and South Wales.
We provide licences for the extraction of marine sand and gravel resources, used in construction projects around the country, as well for beach replenishment and coastal adaptation.
