Metadata: 2010, ABPmer and CMACS, Burbo Bank, Monopile wake and Model Calibration Metocean Survey
Abstract:
This series presents the results of recent metocean survey work undertaken at the Burbo Bank Offshore Wind Farm, designed to address two outstanding licensing conditions: 1. Tidal Model Validation: There were concerns regarding the original tidal current data collected at the site and used to inform and validate the tidal model used in the original EIA study. To revalidate the model, new tidal current profile survey data were collected and compared to the model output. The results confirm that the original tidal model performs well in predicting tidal current speed and direction at the site. 2. Tidal Wake Validation: The original EIA study included the conservative prediction of tidal wake effects from an array of 30 turbines on 4m monopiles and the subsequent effect on regional sediment transport rates and pathways. To validate the accuracy of the tidal wake predictions by the model, a field survey was designed and undertaken to measure and map the gross flow properties of the tidal wake associated with the BB27 foundation (a 4.7m diameter monopile with rip-rap scour protection). The results of the wake survey compared closely to the modelled wake in terms of time mean flow properties but also differed somewhat in terms of the lateral extent of the wake in the very near-field (<200m downstream, a limitation of the model associated with mesh resolution) and the presence/absence of locally elevated turbulence (also a limitation of all such regional scale modelling tools). The implications of elevated levels of turbulence being observed in the field but not being present in the model are discussed in relation to the predicted patterns of sediment transport, suggesting that, on balance, the model correctly estimates the effect on sediment transport.

| Internal code | Internally assigned metadata identifier | 18646 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2010, ABPmer and CMACS, Burbo Bank, Monopile wake and Model Calibration Metocean Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Monopile Wake and Model Calibration Metocean Survey |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 49411c08-01a6-4127-8cc2-e5c13ed4df84 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-199 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2010-06-29 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2010-06-29 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Following the completion of all survey work, this report presents a comparison of modelled and measured wake effects as well as a comparison of modelled and measured currents at sites BB1 and BB2 to address the outstanding licence conditions. |
