Battersea River Pier

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.

The Challenge

Legacy marine structures had to be removed from the riverbed and it was originally planned that seven marine piles would be removed using conventional techniques. The piles resisted removal and as a result of its flexible approach and experience the Red7Marine team switched to an alternative method. Having taken into consideration at the project planning stage that it may not be possible to extract the legacy piles, Red7Marine opted to cut the structures off below the river bed level with ultra high-pressure water cutting equipment.

The Solution

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.”

Client relationship

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.

Technical support

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.
