A Review of the Potential Impacts of Marine Aggregate

Aggregate Processing Sand and gravel that is underwater can be harvested by a dredge extending the useful life of the aggregate operation The dredge is used to dig into the bank of materials underwater and then pump the aggregate slurry to a processor on land The sorted material is then used for road construction or other projects Marine Aggregate Dredger 3500 Dredging depth m 55 Hopper capacity m3 Hopper capacity yards3 3500 4577 underwaterpump and screening towers ensure efficient dredging operations The RoRo Deep Dredge which can work up to a 200 m dredging depth has been specifically designed to meet demand from this sector and sets out to Jul 05 2014 The UK marine aggregate industry has approached the assessment of cumulative marine dredging activities through a voluntary Marine Aggregate Regional Environmental Assessment MAREA approach Each MAREA assesses the cumulative impacts of marine dredging activities using regionalscale hydrodynamic and sediment transport models linked to

Between 2002 and 2003 during observations of dredging operations in Geraldton Western Australia it was reported that New Zealand fur seals Arctocephalus forsteri and Australian sea lions Neophoca cinerea showed no sign of disturbance reactions despite the relative closeness of the dredging to popular haulout sights Dredging The nations marine aggregate needs are satisfied by a fleet of 27 purposebuilt marine aggregate dredging vessels operating around the clock 360 daysayear The ships are predominantly registered in the UK and have a replacement cost of between 25 and 50 million each This new standard has allowed a new Level 2 Diploma to be introduced which will allow the relevant crew working on board marine aggregate dredgers to demonstrate their competence when carrying out dredging and discharge operations enhancing and complimenting the Certificates of Competency already held by those working at sea
