Case Study Overview
Scour protection and remediation techniques are used to control erosion in both estuarine and the offshore environments.
Red7Marine repaired the toe protection to the seawall flood defences by locally preparing the ground and using loose rock fill material to prevent further scouring of the riverbed and erosion of the salt marshes.
At a glance
- Location: Fingringhoe, Essex
- Plant used: Work boats, Modular pontoons
- What we did: Red7Marine installed scour protection on damaged sections of the flood defences to preserve areas of the salt marsh at the Fingringhoe firing ranges in Essex.
The Challenge
The site where Red7Marine was operating was very remote and the only access to the site was via the water. Planning and liaison with local stakeholders was carried out by Red7Marine to minimise the impact of the works.
The Solution
After assessing the project requirements, shallow draft road transportable equipment was selected to reach the tidally restricted areas and mobilised to the closest port. Shallow draft workboats towed the modular pontoons loaded with rock to the site location where the rock was carefully placed using a small excavator on a second modular spud leg barge. Correct planning of the works by the Red7Marine’s engineers ensured that there was minimal impact on the sensitive areas of the salt marsh whilst still delivering the project on time and within budget.
Nick Offord, Managing Director at Red7Marine commented: “We are ideally positioned to design and install environmentally friendly scour protection systems, such as at the salt marshes at Fingringhoe. Our risk management team worked with the client to manage the risks and safeguard the fragile environment. Our vast knowledge and skill set is a result of extensive experience in working in these types of environments.”

Alongside the marine construction works, Red7Marine also planned and liaised with its partners throughout the project to ensure safety and excellence.
Environmental awareness
Environmental awareness is integral to Red7Marine, in this particular project, close client liasion was crucial to ensure minimal impact was made on sensitive areas of the salt marshes.
Experienced project partners
Red7Marine was expertly position to offer consultancy during this project, and its culture of safety and respect aided the repair of the seawall flood defences to ensure it was left fully functional.
