Dredging

Marine Dredging | Ireland & UK

Foyle & Marine Dredging’s foundation has been built on dredging ports and harbours across Ireland and the UK since 2008. 

The primary dredging method is the traditional backhoe method, reaching a maximum depth of -19m and with a bucket capacity of 4.5 m3. We have other arrangements to suit large capital, medium and smaller dredge requirements. Dredgers can also be selected to suit a project’s geographical constraints, be it shallow or deep water, bulk or trimming excavation, firm, or soft material, and so on and so forth. Not only do we dredge ports and harbours, but we also have a range of modular barge equipment which is suitable for accessing and dredging inland waterways.  

Usually, the dredge material is disposed of at sea by a split hopper barge. Depending on the dredge size and site location, FMD would select a suitably sized split hopper aligned with production outputs, site access constraints and project programme. It would be common to run two or more split hoppers if the project demanded. Dredge material can be discharged to land alternatively ,if the project requires this method. 

Foyle & Marine Dredging are also experienced in contaminated dredging. Contaminated dredging is usually performed using a closed/visor bucket or clamshell method, where the material is loaded into a hopper barge and then discharged to land for further onward treatment and disposal.
