Kirtling Street

Case Study Overview

The £4.2bn Thames Tideway Tunnel project is delivering a major upgrade to Londons sewerage network. A new tunnel will be constructed from Acton in the West, to Beckton in the East to reduce CSO discharges into the River Thames. 24 construction sites are required for the project with 11 locations spread along the river where the sites are required for the tunnel construction. Various works including cofferdams and marine jetties are being installed to allow construction materials and spoil from the tunnels to be transported via the River reducing HGV movements across London.

At a glance

  • Location: River Thames, London
  • Plant used: 250t jack up barge. 28m – 60m Flat top barges
  • What we did: Red7Marine supplied heavy marine equipment for clients to construct the marine jetty.

The Challenge

The River Thames is a very busy river at the heart of one of one of the worlds busiest cities. It is used as a major transport link across London as well as for commercial traffic and tourism.

The tidal River Thames has up to a 7m variation with major road, rail and pedestrian bridges crossing the river along its length. Our client required a 350t crawler crane to be loaded onto a 50m x 18m flat top barge and transport it to Kirtling Street site from the Port of Tilbury.

The Location

The Kirtling Street Thames Tideway site is located close to Battersea Power Station. Along the route there are 13 bridges along the River Thames to transit under between the Port of Tilbury and the site.

Detailed passage plans of commercial vessels are required to ensure the safe transit and co-ordination with other river users and stakeholders.

The Solution

Red7Marines engineering team carried out all of the heavy loading calculations and ballasting procedures to check to stability during loading and operation. Detailed risk and method statements were prepared before the crawler crane was successfully loaded onto the floating barge under the careful supervision of one of the senior engineers.

Passage plans were prepared and submitted to the PLA for approval to ensure that there were sufficient air draft clearances on the bridges. Finally, the 50m x 18m crane barge was successfully delivered to site in accordance with the documentation.
