Project outline

Murphy was awarded the contract to develop the Nemo Link Ltd converter station in Richborough, Kent. The project involved the construction of three steel portal frame buildings and various ancillary steelwork elements.

The Murphy steel fabrication unit were responsible for the detailed design of all connections (including those for the large span roof trusses), fabrication, galvanising, erecting the frames and associated secondary steelwork.

Key challenges

Designing the roof trusses to meet the design criteria, and also to enable efficient fabrication and assembly on site, was a key challenge on this project.

Project delivery/innovations

Murphy was contracted by Siemens to construct three steel portal frame buildings, as part of the Nemo Link converter station project. The main building was 135m long by 37m wide by 22m high. It had a clear internal span with a total of weight of 550 ton. The second building was 32m by 19m with a weight of 25 ton. Finally, the third building was 19m by 14m and 42 ton.

The connection design was completed by our in-house designer and the works were coordinated by the dedicated, steel unit management team. This consists of six people that cover management and design fabrication drawing, in addition to inspection and welding management. A team of fifteen to twenty people are directly employed in our workshop and installation is managed by a project manager with a team of experienced steel erectors.

Our key suppliers of steel are British Steel and National Tube Suppliers. We utilise galvanisers and painters both in Ireland and the UK.
