Mackley: New Flood Defenses for Littlehampton

Image source: Mackley

Mackley has completed a project to fill a 28-meter gap in the flood defenses in the West Sussex town of Littlehampton – in turn reducing the flood risk for 2,000 homes.

Working as part of Team Van Oord and on behalf of the Environment Agency, the £680k, 20-week project included organizing the planning application and producing the detailed design, followed by installation of a sheet piled wall and concrete capping beam alongside the River Adur.

Investigations showed the existing river wall to be in a very poor condition, while the works would have to be carried out in a tricky location with restricted access.

“To overcome these constraints, the new stretch of river defense was placed in front of the existing defenses, further into the river. This had the benefit of shoring up the existing defenses and meant that piling was through new river bed ground. It also limited disturbance to the local community, thereby helping to gain planning approval,” Mackley said in their release.

The installation of the sheet piles took place from a jack-up barge, supporting a 70t crawler crane. The barge arrived in a good weather window, having been transported from Tilbury.

The barge was then towed into the harbor and loaded with equipment – before being towed along the river, floated through a pedestrian bridge and moved into position at the work site.

The project was completed with a backfill between the new and old defenses of self-compacting granular fill.

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
