Metadata: 2012, EGS, Lincs, Hydrographic Surveys of Lincs Export Cables
Abstract:
EGS (International) Ltd was contracted to undertake a hydrographic, post-construction survey of the LINCS offshore wind farm export cables extending from the substation to the 0 metre Chart Datum (CD) contour. Whilst survey operations were underway, the contract was extended to cover a hydrographic survey to assess seabed scour around 4 wind farm turbine bases and any cable exposure along the collector and inter-array cables, as well as a sub-bottom survey around the Westmark Knock Navigation Buoy in the Wisbech Channel. The survey aims were as follows: a) Conduct a survey of the export cable routes to identify any exposure of the cable or change in seabed morphology. b) Survey (using SSS) around three faces of the Offshore Platform (OSP) to check the cables exiting the J-Tubes to their touchdown point on the seabed. c) Obtain Sub-bottom data around the Westmark Knock Navigation Buoy in the Wisbech Channel. d) Conduct a scour survey of the seabed at the base of 4 turbines within the LINCS Offshore Wind Farm. These 4 turbines were LS61, LS62, LS63 and LS64. e) Survey (using SSS) the inter array cables to identify any cable exposure.

| Internal code | Internally assigned metadata identifier | 19048 |
| 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. | 2012, EGS, Lincs, Hydrographic Surveys of Lincs Export Cables |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Hydrographic Surveys of Lincs Export Cables |
| 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. | 86d49e4a-50df-47c5-8e4a-241d526bd87f |
| Resource Identifier | This is the code assigned by the data owner. | TCE-949 |
| 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 | 2012-10-29 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2012-11-11 |
| 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. | The Seatex Seapath 330+ system with C&C Technologies positioning corrections was used as primary horizontal control throughout survey operations. The Leica 1200 GPS system, set to log raw observations at 1-second intervals, was used for the vertical control throughout survey operations. The raw GPS observations were then postprocessed with Ordnance Survey Active station data using Leica Geo Office 7.01. Horizontal positions are presented as Eastings and Nothings relative to WGS84 UTM Zone 31 North. Vertical positions are presented relative to CD (Skegness). The offsets between the MBES transducers, the MRU, the DGPS antennas, equipment tow points and the CRP, where the Wessex Explorer datum has been established, were accurately measured (± 0.001metre) during a dimensional survey conducted in June 2012. All offsets were input to the Seapath 330+ system which calculates the actual position for each instrument. All position measurements were acquired relative to the WGS84 Ellipsoid (latitude and longitudes) and then converted to Eastings and Nothings relative to WGS84 UTM Zone 31 North. |
