Case Study Overview
The Emirates cable car was installed to provide a pedestrian link across the River Thames between the Royal Docks and the Greenwich peninsula.
Red7Marine provided the project with all the marine equipment in the tidal River Thames to install the foundations for the South support tower and the station foundation in the Royal Victoria Dock. Ship impact protection was also installed at both sites to safeguard both structures.
At a glance
- Location: Greenwich, London
- Plant used: Haven Seaway, Haven Seabreeze, Haven Seafield, Haven Seavoyager, Haven Seareach, Haven Sea Supporter
- What we did: Red7Marine worked with Bachy Soletanche in a joint venture to install the foundations for the one-kilometre long cable car.
The marine plant supplied to the project consisted of two jack up barges, the Haven Seajack 1 and the Haven Seaway, supported by the Haven Seareach crane barge, Haven Seavoyager and the Haven Seabreeze flat top supply barges. The Haven Seasupporter tug with additional workboats moved the equipment around between the locations.
Temporary access walkways supported on tubular steel piles were installed from the riverbank to the South tower foundation which also supported the pumped concrete supply lines. The walkways allowed the efficient and safe transfer of personnel to the work site.
As Red7Marine was operating close to the London City Airport flight path and on a busy stretch of the tidal River Thames there were additional operational constraints which required close liaison with important local stakeholders. The management team worked closely with LCA and the PLA to gain approval of the construction methodology and the project programme, ensuring that the project was carried out with the minimal disruption.
Nick Offord, Managing Director at Red7Marine commented:
“The Emirates Cable Car is a popular tourist attraction and essential local travel connection. Consequently it was important for us to liaise very closely with the local stakeholders at all stages of the project and our flexibility as an agile business enabled us to quickly respond to the evolving project requirements.
Our team are committed to providing the best solutions and project management to each and every client.”

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.
Battersea River Pier
Red7Marine secured a contract at Battersea in December 2016 to install new tubular driven steel mooring piles for the Battersea Power Station river bus pontoon installation which is planned to be operational in Autumn 2017. Transport for London (TFL) decided to extend the river bus service after the number of housing developments at Battersea began to increase.
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.
