Description

Osiris Projects were commissioned in October 2013 by Centrica Renewable Energy
Ltd. (CREL) to carry out post-construction surveys on the LINCS Offshore Wind Farm
(OWF) and associated export cable route. There were six key elements of the surveys:
 LINCS OWF repeat pre-construction benthic baseline survey
 LINCS OWF drill arising mounds benthic survey
 LINCS OWF export cables
 LINCS OWF site post-construction survey focussing on the Inter Array Cables
(IAC)
 LINCS OWF site post-construction survey focussing on the No Cable Zones
(NCZ)
 LINCS OWF site scour surveys at turbines LS61 – LS63.  The aims of the surveys were to:
 To repeat the pre-construction benthic baseline survey (2010) in order to satisfy
Marine Licence Annex 1.
 To sample four of the sixteen drill arising mounds present on the site.
 To ground truth any distinct seabed features consistent with Sabellaria reef
formations, identified via SSS within the No Cable Zones (NCZ).
 To undertake a 100% coverage swath bathymetric survey around a sample of
three adjacent turbines, 61, 62 and 63.
 To assess the extent if any changes to bed form morphology along the interarray
cable routes.
