Metadata: 2016, Cathie Associates, Walney Extension, Cable Burial Risk Assessment
Abstract:
A burial risk assessment has been completed for the export cable route and the infield cables planned for the extension of the Walney Wind Farm. There are to be two Export cables, one from each OSP to transmit the power from the wind farm to shore, 87 No. inter array cables and an interlink cable connecting the twoOSPs. The cable route length forWOW03 is approx. 75km and for WOW04 is approx. 62km. It is anticipated that one offshore joint will be made at KP28-32 on each cable, due to its weight and volume. The aim of this burial risk assessment is to develop a recommended cable burial depth across the array and along the export cables excluding potential sediment mobility allowance. This revision incorporates a more detailed AIS data assessment and a Ground Investigation Report. Where applicable, the Carbon Trust CBRA [Ref. 32] approach is adopted, particularly in relation to the probabilistic assessment of anchoring.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Where applicable the basis of the methodology used in this assessment was the DNV guideline DNV-RP-F107 Risk Assessment of Pipeline Protection [Ref. 3] which complies with the recommendations of DNV-RP-J301 [Ref. 39] and is consistent with the methodology outlined by the Carbon Trust Cable Burial Risk Assessment Guidance [Ref. 32 & 33]. The method reviews an identified hazard based upon the likely frequency of occurrence and the consequence of the hazard. This method is applicable to primary hazards to cables such as shipping. In regards to secondary hazards such as mobile sediment the risk is that of increasing the frequency or consequences of a primary hazard. When deciding upon a burial depth other considerations which should be taken into account including heating effects and installation risk. |
