Due to the protected status of the environment in the Wash and its sensitivity to disturbance, it is critical that the engineering methods proposed for installing the cables from the sub-tidal, through the inter-tidal and across the mudflats on to land is given due consideration. Centrica has committed to deliver sufficient detailed data for the ‘appropriate assessment’, a key part of the consenting process for this project. It is critical to the ongoing project development process that this is achieved and that the information presented at the appropriate assessment is complete. The main objective of this desk top study is to summarise the methodology and tools likely to be employed for the installation of the export cables. The methodology described is that which is thought to have the lowest environmental impact and the highest cable integrity reliability at the time of writing. The benefits of sub marine cable burial include mechanical protection of the cable and possibly reduced long term environmental and visual impacts.
