Mott MacDonald has been selected as design engineer by contractor VolkerStevin for the deepening of two existing berths, 201 and 202, at Southampton’s Western Docks in the UK.
Associated British Ports (ABP), which owns and operates the Port of Southampton, is planning to increase the terminal’s container throughput capacity by accommodating future generation container vessels and carrying out other port upgrades.
Work will include deepening of the existing 600m quay by up to 6m to allow container vessels of up to 18,000 teu to access the port at their fully loaded draught, and installing new ship-to-shore gantry cranes with an outreach of over 60m.
Under the deal, Mott MacDonald will provide the design of the main quay, paving and drainage for the terminal and the preparation and management of a new ground investigation.
Mott MacDonald will also oversee structural inspections and testing of the existing quay, in addition to providing the detailed design and specification of all civil works related to the project.
Project director Richard Stephens said that the development will reuse existing quay materials such as concrete and backfill extensively in new construction.
"We plan to undertake sophisticated numerical modelling of both the existing and new quay structures to accurately assess their interaction and behaviour as a homogeneous structure," Stephens said. "This will allow us to optimise structural efficiency by utilising residual capacity of the existing quay in the design of the reconstructed quay."
Design work is scheduled to be completed by the end of 2012, while construction is expected to be finished by the end of 2013.
Mott MacDonald’s work is part of a larger project, started in September 2012 by DP World Southampton and ABP, to build a new £150m quay at the Southampton docks container terminal
The new quay will be built by combining the two existing berths, 201 and 202, to help the container terminal accommodate the next generation of ultra-large container carriers (ULCCs).
The new berth, scheduled to be complete by December 2013, will be 500m long and 16m deep and will be able to handle four 400m vessels of 16,000teu capacity.
Operations at the new quay, which will be equipped with five ship-to-shore (STS) super post-panamax cranes, are expected to start in January 2014.
