Case Study Overview
Red7Marine secured a contract at Battersea in December 2016 to install new tubular 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) came to the decision to extend the river bus service after the number of housing developments at Battersea began to increase.

- What we did: Red7Marine installed new tubular steel mooring piles for the Battersea Power Station river bus pontoon
Tubular steel piles are commonly used marine environments as they are relatively light, robust and can be driven deep into the bearing stratum. The piles were installed to very accurate tolerances and were successfully driven 15m into the river bed using conventional piling hammers.
Red7Marine used the Haven Seaseven jack up barge and Haven Seareach flat top barge. The marine fleet was managed and prepared in-house to carry out the complicated mobilisation which involved transiting the River Thames through central London under several bridges. Once on site, the jacking legs were installed in the barge and the 120 tonne crawler crane was transferred from the Haven Seareach flat top barge on to the Haven Seaseven jack up barge.
Commercial Director at Red7Marine, Kristen Branford commented: “It was extremely exciting for Red7Marine to announce the marine construction works at Battersea Power Station. Red7Marine’s strong history of safely delivering complex and challenging projects was demonstrated again during this project just as it was during the London Cable Car and the London Gateway projects. We worked closely with our project partners at all times to complete another successful project on time and on budget.”
John Ronayne, Senior Project Manager at Battersea Power Station Development Company, said: “We were very impressed by the services and assurance we received from the Red7Marine. From the project planning stage, right through to the completion of the project, the team at Red7Marine provided outstanding expertise and delivered a superb end result. Red7Marine’s proficiency working on the River Thames and its ability to carry out specialist marine construction works made them the perfect project partner.”
Red7Marine’s client relationships are extremely important, Red7Marine liaised closely with the Port of London Authority (PLA) and local stakeholders who regularly use this busy section of the river. The team consulted closely with the client throughout and provided a full project management team to ensure that the work was carried out to the highest safety standard.
Proven track record
With an extensive portfolio of construction projects working on the River Thames, Red7Marine was chosen for the project because of its proven track record.
Red7Marine’s specialist teams and equipment are capable of providing various piling solutions and have the ability to remove existing marine structures from the river bed. The dedicated and committed team provided by Red7Marine were highly experienced and multi-skilled minimising the number of men required on site.

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.
