Thunderer Jetty – Stolthaven
THE BRIEF
Robert West Consulting (RWC) was appointed by Stolthaven Terminals to provide design services for the redevelopment of Thunderer Jetty, a bulk liquid storage terminal at Dagenham on the Thames Estuary.
The scope of the development was to demolish, remove and refurbish the existing berth structures and to construct a new jetty approach, breasting dolphins, mooring dolphins and a new jetty head to provide an extended life of 40 years and to meet the latest safety and environmental standards.

RWC developed a design comprising of repairs to the existing downstream dolphin allowing re-use, new mooring / berthing dolphins, new steel truss bridge jetty approach and a precast concrete jetty head/ loading platform. RWC also defined the required monitoring regime for the existing structures during the piling works, whereas the pile caps design allowed delivery by road as a preassembled twin (pile trousers hat) unit, resulting in efficient lifting installation sequence by positioning accurately using adjusting screws.
Furthermore, RWC developed the temporary berthing & mooring work designs to allow all the piles to be installed within the Winter 2022 piling window, by implementing a bespoke crucifix frame welded to the main berth piles to locate temporary bollards and to restrain pneumatic fenders at the berthing line. Finally, RWC onsite presence during the construction period allowed prompt construction support to the Contractor and commercially assisting the Client as required throughout the project.
