DP World London Gateway
Overview
- Client: Mclaughlin and Harvey
- Project Value: £5m
- Dates: July 24 – Feb 25
GPS MACS Ltd were contracted by McLaughlin and Harvey to install the scour protection system in front of the newly constructed Berth 4 at DP World London Gateway Port. The development of Berth 4 is a westward expansion of the container terminal to accommodate future demand for container handling at the Port.
A complex and challenging project in both scope and environmental conditions. In addition to the inherent install challenges, we are operating within a live port, a section of river with fast current speeds limiting installation to slack water only, and black water working with no visibility.
The key to our success was the in-house innovation built into the methodology:
- Designed and fabricated temporary works system welded to the stern of the barge, guiding the lifting frame into final position using hydraulic rams, guide piles and gates.
- 4 mattresses per lift with a bespoke lifting frame designed specifically for this project.
- Dive teams equipped with our Aris 3000 Sonar System, providing visual confirmation of installation tolerance
- Worked 24/7 rotating shifts tidally throughout the project.
Installation of the Pipeshield flexible concrete mattresses along the toe of the new quay wall.
The mattresses were placed on the riverbed at a depth of 25m and with an installation tolerance of 100mm.
Each lift was 65T from the floating crane barge, which accounts for 4 mattresses and the lifting assembly.
Mobilisation / demobilisation of 500T crawler crane on 75 x 22m pontoon. We carried out this operation in the Netherlands and towed across using in-house fleet on pontoons and tugs.
