The Challenge
Works spanned from Hammersmith Bridge to Lewisham, covering 19no. Borehole locations. Efficient project management was vital to the success of this project, ensuring careful planning of all barge moves through the various Thames Bridges and constant coordination with the client and Port of London Authority (PLA).
Red7Marines, crane barge comprising of 30 x 18m flat top barge Haven Seaforth and 110Ton Eiger crawler crane were supplied to assist in the Jack – Up site moves. This enabled the Jack-Up legs to be removed and stowed on the deck of the barge so that all bridges between Borehole locations could be transited safely and efficiently whilst keeping to a strict time schedule. The project also utilised Red7Marine’s Damen built tug, the Haven Supporter and safety boat the COMIII.

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.
