Metadata: 2014, MMT, London Array, Site And Export Cables Bathymetric Survey (Autumn)
Abstract:
As part of the post construction monitoring at the London Array Offshore Wind Farm, a geophysical (bathymetry & backscatter) survey of the 4 export cables (HV1 – HV4), cable crossings, selected WTG locations and array cable corridors at the London Array Wind Farm (LAW01) is required by the authorities. London Array Ltd sees the need to evaluate the asset integrity due to the dynamic seabed environment. At the wind farm site, extensive scour holes of depth up to 9m deep have been observed. The objective of the survey is to accurately map the extent of the scour holes and assess the development since the last survey (April 2014) and the overall development since pre-construction (2010).

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This survey represents DONG Deliverable 752. The vertical datum is LAT. GNSS (Global Navigation Satellite System) tide is used to correct the bathymetry data to the defined vertical datum, LAT. The GNSS-tide is obtained by post-processing GNSS-data collected by an Applanix PosMV 320 system. The GNSS-data is post-processed in the software POSPac MMS. Both the POS MV and POSPac MMS are developed by Applanix. The output from POSPac is ellipsoidal heights with accuracies of 5 cm RMS and are corrected for motion and referenced to the multibeam reference point. By incorporating the UKHO VORF-LAT model into the process, the heights will be referenced to LAT. Comparisons with the closest water-level station will be done to ensure that the data is levelled correctly. |
