Details
Alongside the various studies being carried out as part of the government’s Severn tidal power feasibility study, the assessment of the possible constraints in terms of supply chain is also an important consideration in any decision on whether the Government could support any option.
The implementation of a tidal scheme in the Severn estuary, especially a large one (or a combination of smaller schemes), would require not only a great amount of materials and equipment but also large scale innovative construction design and installation processes (numerous caissons, long embankments, sluices, locks etc). Although most of the technologies and construction design are proven and mature, the magnitude of the largest schemes would require a multi-national joint venture.
In order to make sure the regional, national and international market will be able to meet the project’s likely level of demand, a supply chain survey has been undertaken. This survey is based on the responses to a specific questionnaire sent to Trade Associations, Manufacturers, Contractors, Ports and other bodies, and also on existing reports.
