2015, Osiris Projects, Burbo Bank Extension Offshore Wind Farm, Geophysical UXO Survey

Description

Osiris Projects were commissioned in January 2015 by DONG Energy to carry out a geophysical and
UXO survey at the planned Burbo Bank extension Offshore Windfarm site. The survey was completed
under Osiris Projects Terms and Conditions.   The main site survey, the northern section of the export
route and Option 1 environmental survey were carried out
between 16th February 2015 and 11th April 2015 on board the MV Bibby Tethra.
Following demobilisation of SV Bibby Tethra on the 11th April 2015 a small number of bathymetric and
magnetometer infills were identified during processing. These infill lines were completed by MV
Proteus and MV Chartwell, which were on site working on the southern sections of the export route.
MV Proteus mobilised for the job on the 22nd‐24th April 2015, and demobilised on 27th June 2015. MV
Chartwell mobilised for the job on the 18th and 19th of May 2015, demobilising on the 5th June 2015.
The main objectives of the survey were to provide:
1. High resolution bathymetry. 
2.  Geomorphologic features on the seabed
3. Identification and quantification of possible biogenic reefs.
