Bi-annual campaigns are undertaken Bi-annual campaigns are undertaken with dredge volumes in the order of 400,000m³. Dredged materials generally consist of silts and sands.

Dublin Port Capital Dredge Works

Irish Dredging were awarded the contracts for the Season 2 and Season 3 capital dredging works; working to stringent EPA licence conditions over 2,100,000m³ of fine to medium sands, with the occasional gravel and clay lenses removed from the navigation channel, which was deepened at a new design depth of -10m CD.

Rosslare Maintenance

Maintenance dredging of 90,000m³ of sands and gravels from the Approach Channel, Inner Harbour and adjacent areas to a design depth of -8.0m CD. The works were executed using our small trailer dredger ‘Sospan Dau'.

Drogheda Term Maintenance

Cill Ronain Harbour Development

The project required dredging of hard rock which was pre-treated by drilling and blasting prior to being dredged to the required design depth. The dredged rock was re-used in the breakwater construction with additional rock armour to protect the breakwater imported from a local quarry.

Foynes Maintenance
