Jeanie Johnston

Commissioned by Dublin City Council, and working alongside Purcell Construction, consultant engineers RPS and architect Urban Agency, we delivered a two-phase floating platform solution that enhances access and experience around the historic Jeanie Johnston tall ship.

The Jeanie Johnston is a full-scale replica of the original 1847 famine ship that carried over 2,500 emigrants to North America during one of the darkest periods in Irish history. Moored at Custom House Quay, the ship is a central part of Dublin’s maritime and cultural landscape – and the new pontoons ensure this story can continue to be shared with the public, safely and sustainably.

What we installed

In Phase 1, we fabricated and installed a breakwater pontoon system made up of six units (2 x 20m x 5m and 4 x 20m x 2.5m), forming a large 40m x 10m platform. This included a dedicated 20m x 4m pontoon to provide additional stability and functionality.

The project presented several complex challenges – most notably, the integration of the new pontoons with existing infrastructure, particularly in achieving consistent freeboard levels. This required close coordination between our team and engineers at RPS, as well as ongoing adaptation on-site.

Working on a project that honours such a significant piece of Irish heritage was both a privilege and a technical challenge, as the installation also supported a 30-ton Glulam structure on the floating platform – requiring precision planning and engineering to ensure balance, load-bearing capacity and safe towage into inner-city Dublin.

In Phase 2, we returned to fabricate and install a second Glulam-supported platform – 15 tons this time – alongside two more 20m x 4m units. This phase also incorporated a gangway to improve access and functionality for both tourism and operational users.

Supporting tourism and First Responders

While the project is part of an expanded tourism offering – complementing the new Jeanie Johnston Experience visitor centre on land – it also improves the operational base for Dublin City Fire Brigade and provides upgraded access for small leisure craft.

The enhanced platform can accommodate more footfall safely and seamlessly connects with the surrounding dockside landscape. This installation is now a key part of how people engage with Dublin’s Docklands – educationally, historically and recreationally.
