The Bathymetric surveys were to cover the 4 export cables corridor as laid and with a buffer of 25m either side of the outermost cable. The vessel mobilisation was carried out in Ramsgate between 27th and 30th August 2013. The bathymetric survey work was carried out onboard the Wessex Explorer between 27th August and 09th September 2013. The survey equipment was demobilised from the vessel on 9th September 2013 in Ramsgate. Data were collected in ETRS89 Datum with RTK corrections supplied from LAL (Dong London Array) /Dansurvey setup. The VORF model was utilised to reduce data to LAT and for comparative purposes a surface with a fixed offset of 42.1 was also created in order to compare the 2010 and 2013 datasets. Data comparison between the 2010 and 2013 datasets show general movement of sediment in certain areas along the route with the majority of sandwave migration occurring in the outer cable route east of the Kentish flats.

MV Wessex Explorer is permanently mobilised with a suite of hydrographic equipment including a V5 Applanix POS MV 320E, hull-mounted Kongsberg EM3002D Multibeam Echo Sounder (MBES) and a C&C Technologies C-Nav 2050 DGPS. A Leica 1200 GPS was also installed to acquire precise vertical measurements, allowing near-real-time computation and normalisation of the tide element prior-to post-processing of the V5 Applanix POS MV 320E data with POSPac MMS 6.2. On 15th May 2013, Geo-Spatial Survey Solutions conducted a Reference Frame Survey (RFS) of MV Wessex Explorer whilst the vessel was on a hard stand in Gosport shipyard (Hampshire, England). The full RFS survey report is included within this document, as Appendix A. Land survey and photogrammetric techniques were used to establish sensor offset locations & orientations relative to the vessel reference frame (established by the RFS). The horizontal and vertical origin of coordinates, the common reference point (CRP) (x = 0.0000m; y = 0.0000m; z = 0.0000m), was defined as the centre of the indicator on the top of the V5 Applanix Type40 IMU (Figure 3), in close proximity to the vessel’s centre line. The V5 Applanix Type40 IMU was installed away from the MBES transducers in order to provide line-of-sight for the RFS, thereby maximising RFS precision and accuracy.
