Case Study Overview
The Great Yarmouth Third River Crossing is one of Norfolk’s most significant infrastructure projects in recent years which is being delivered by the BAM Farrans Joint Venture. BAM Farrans began on site in January 2021, before beginning the overwater marine works and construction later in the year. Once complete, the bridge will link the A47 at Harfrey’s roundabout to the port and the enterprise zone on the other side of the river, easing traffic congestion and improving journey reliability. The bridge also supports the county’s wider plans to maximise investment, regeneration, and economic growth opportunities in the area.
At a glance
- Location: Great Yarmouth, Third River Crossing
- Plant used: Haven Seariser 3 250T Jack-up Barge
- What we did: Red7Marine supported the BAM Farrans JV for the construction of the Third River Crossing.
The Solution
Red7Marine’s 250t deck capacity Haven Seariser 3 jack-up barge was mobilised to site in April 2021 to facilitate the marine works which involved the excavation of the quayside and installation of piles to form the foundations for the Western and Eastern Bascule pits. Construction will now continue with plans to have the bridge operational and open to traffic by early 2023.
The piles were driven from the Haven Seariser 3 with the use of a piling gate to successfully guide them into position. Jack-up barges are ideally suited to marine piling operations, providing stable level platforms when working in overwater conditions.
Richard Hayman, Construction Manager for BAM Farrans comments:
“The project is continuing well and the Red7Marine team have played a big part in the success of the cofferdam piling works. The two cofferdams are an excellent milestone as we continue to bring this important infrastructure to life. The spirit of cooperation between all involved has been exemplary and we look forward to working with Red7Marine in future.”

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.
Brighton Marina
Phase 2
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.
Oldbury
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.
Weston-Super-Mare
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.
