Case Study Overview
Red7Marine was contracted by Mackley Civil Engineering to support critical flood prevention works in West Sussex. Mackley Civil Engineering carried out the works under the Arundel Tidal Defence Scheme (ATDS) on behalf of the Environment Agency and once complete, will improve flood defences in the town of Arundel.
Our Haven Seajack 3 jack-up barge was floated into position which the Mackley s team then used as a stable platform from which to install a new flood defence wall made of steel sheet piles along the River Road stretch
of the ATDS.

The Arundel Tidal Defence Scheme (ATDS) has been accelerated to quickly reduce the risk of flooding and erosion to properties in Arundel. Mackley Civil Engineering was awarded the contract and Red7Marine supported the works with the provision of its 100t jack-up barge. The Mackley s team carried out the following works from Red7Marine’s Haven Seajack 1:
- Installed a sheet pile wall
- Drilled and installed tie rods. This involves drilling off the side of the barge at an angle of approx. 45degrees, through the sheet pile wall and into the riverbank behind. Once holes are drilled tie rods are inserted then grouted in place.
Red7Marine used its adaptability to ensure Mackley’s needs were fulfilled with no risk posed to Arundel’s community. This included having a Red7Marine Barge Master on-site at all times. All government guidance was followed due to the project continuing throughout the Coronavirus pandemic and Red7Marine’s services were delivered in a timely manner.
Due to this project’s time sensitive nature and significance among members of the local community, Red7Marine’s plant continues to be carefully managed as the team shares its expertise and support to maintain the efficiency of this installation.
The Red7Marine team is working closely with Mackley’s, combining our areas of expertise to deliver exceptional results for Arundel’s community. As Red7Marine works alongside Mackley’s talented team, we are aligning our commitments to health and safety on the ground.
Red7Marine’s Haven Seajack 3 jack-up barge is being used in the project as a result of its adaptability. A jack-up barge is fitted with long legs which can be raised and lowered into the riverbed, securing its position. The legs can then be raised to move this barge as and when it is required.

Westminster Pier Extension
The Westminster Pier Extension allows more frequent River Bus services between Woolwich and North Greenwich to Westminster. The extension is a key part of the River Action Plan to improve TfL’s piers and increase capacity for passengers before 2020. Red7Marine designed and built a custom pile gate for the project. The barge was reviewed to support a 180t crawler crane for piling operations and was then further reviewed with an additional RH28 drill rig on board.
In order to accommodate a new luxury apartment block in Brighton, part of the marina needed to be reclaimed using sheet piled cofferdams. This would enable the water to be kept out and foundations to be built for the stunning seafront properties. Red7Marine supported the installation of a sheet pile twin wall cofferdam.
Red7Marine installed replacement Active Effluent Discharge Lines at Oldbury power station as part of the on-going care and maintenance works. Red7Marine’s previous project experience on similar projects consisting of works on subsea pipeline and outfalls at Bradwell and Sizewell nuclear power stations, positioned the company as the ideal marine partner for client, Magnox.
Emirates Cable Car
The Emirates cable car was installed to provide a pedestrian link across the River Thames between the Royal Docks and the Greenwich peninsula. Red7Marine worked with Bachy Soletanche in a joint venture to install the foundations for the one-kilometre long cable car using marine rotary bored piling.
Middleton Sands Navigation Marker
This fast turn-around marine construction project involved the installation of a new tubular steel navigation marker pile at Middleton Sands, Barrow-in-Furness in 2017. The navigation marker was required to identify the sub surface obstructions and enable other vessels in the area to operate safely.
Liverpool 2 Deep Water Port Extension
Red7Marine was the marine partner of choice for BAM Nuttall when they constructed a piled combi-wall as part of the Liverpool 2 Dock Expansion that began in 2014. The construction of the container terminal was supported by four of Red7Marine’s jack up barges; the Haven Seariser 1, Haven Seariser 2 and the Haven Seariser 3 and the Haven Seajack as it carried out rock socket piling works.
The Red7Marine team was chosen to provide specialist marine plant and personnel to aid the redevelopment of the Weston-super-Mare Grand Pier after it was destroyed in a fire in 2008. Red7Marine supplied the Haven Seajack 4 assisted in the pier construction works. Its previous experience in pier and marina construction works made it the ideal project partner for this development.
Bradwell Power Station Barrier Wall Removal
Red7Marine is a leading provider of equipment for marine demolition and is skilled in dismantling structures that are beyond the reach of ordinary demolition contractors. In 2012, Red7Marine removed approximately 800 tonnes of steel in the Blackwater Estuary from the Bradwell nuclear power station water intake structure.
Fingringhoe Firing Ranges
Red7Marine installed scour protection and provided remediation on damaged sections of the flood defences to preserve areas of the salt marsh at the Fingringhoe firing ranges in Essex. Scour protection and remediation techniques are used to control erosion in both estuarine and the offshore environments.
