Cardiff Marine Services Completes Porthcawl Marina Dredging

During January 2018, Cardiff Marine Services was contracted to carry out maintenance dredging at Porthcawl Marina over 21 tides. 

Throughout the dredging works, conducted by water injection method, an average of 1.3  to 1.5m of silt was removed from the dredged area. The majority of the dredging exercise reduced the levels down to the original bed level.

Water injection dredging uses water pumps connected to a series of nozzles on a horizontal jet bar. The nozzles inject large volumes of water at low pressure directly onto the sediment build up.

This process fluidises the sediment build up, turning it into a density current which is then able to flow horizontally out of the channel or port. This process eliminates the need for traditional excavation dredging methods and the subsequent transportation of the dredged material.
