Contracted by DONG Energy, the company recently completed site operations on the newly installed export cable of Burbo Bank Extension.
With a capacity of up to 258 MW, the site generates enough energy to meet the average needs of up to 230,000 homes, and is located in Liverpool Bay close to Bibby HydroMap’s head office.
The work involved two of the company’s vessels; Bibby Athena and Lia, mobilised with a suite of high specification survey equipment to acquire multibeam bathymetry, side scan sonar data, sub bottom profiler data and cable depth of burial data. Cable depth of burial data was acquired by Bibby Athena using Bibby HydroMap’s Dynamic Remotely Operated Survey Platform (d’ROP) equipped with PanGeo Subsea’s Sub Bottom Imager, completing the 24km route in 2 operational days.
It was very pleasing to see the Bibby Athena carrying out her depth of burial operations so safely, efficiently and to good effect over the Burbo Bank Extension Export Cable. The development of the use of the Dynamic Remotely Operated Survey Platform (d’ROP) with the PanGeo Sub Bottom Imager over the last 2 years has lead to a very competent operation. I was pleased to see it utilised effectively for the first time on this project. It was of great benefit to the project to have Bibby be able to present the findings in person to the us DONG Energy at our offices shortly after demobilisation, and even during operations for specific interrogative tasks, for which the Bibby team were very flexible. I look forward to using the setup again on more planned cable depth of burial works
