Lymington Viaduct Christmas Blockade Wk39/40/41: A Successful Collaboration!
This festive season, Rebel Marine, in partnership with Octavius Infrastructure and the Network Rail Southern Renewals Enterprise, accomplished a significant milestone in the blockade works for Lymington Viaduct.
Constructed in 1884, this impressive 10-span structure plays a crucial role in carrying the railway over Lymington Harbour, providing vital access to the Wightlink Isle of Wight Ferries.
The viaduct is supported by nine pairs of piers that uphold the main girders, with cross girders connecting them to support rail bearers, which in turn hold the track on specially designed hardwood wheel timbers.
Our team operated 24 hours a day for 15 days, completing 46 shifts. On-site, we utilized an array of equipment, including:
- 2 workboats
- 460m² of modular pontoons
- 2 crane pontoon barges with spud legs
- 1 spider crane
- 1 marine knuckle boom crane
- 2 tower lights
The initial task involved deploying modular pontoons and workboats to facilitate the installation of scaffolding beneath the viaduct. Once that was set up, our spider crane, mounted on the modular pontoons, was able to lift out the old rail bearers and install the newly fabricated replacements, along with various other materials and equipment essential for the project. The modular pontoons had been pre-loaded further down the river before the blockade and were then floated into position to serve as temporary storage.
Throughout the blockade, the crane and pontoons provided ongoing support, and once the work was completed, they were used to demobilize equipment and transport redundant materials back downstream for unloading. Thereafter, our focus shifted to the removal of scaffolding to prepare for the next phase of works.
We are especially grateful to our partners at Four Tees Engineers Ltd., Amber Scaffolding, EIS Services Group, and Sonic Rail Services Ltd. The dedication and teamwork across the entire supply chain were key contributors to the success of this project. Thank you to everyone involved!
