Bibby HydroMap Completes Export Cable Ops at Burbo Bank Extension

Bibby HydroMap has completed the depth of burial operations over the newly installed export cable of DONG Energy’s 258MW Burbo Bank Extension offshore wind farm in Liverpool Bay.

The work involved two of the company’s vessels, Bibby Athena and Lia, mobilised with a suite of 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 24-kilometre route in two operational days, the company said.

”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,” DONG Energy Project Manager Gareth Ellis said.

Burbo Bank Extension was fully commissioned in April 2017, becoming the first wind farm to utilise 8MW wind turbines on a commercial scale.

The wind farm is a joint venture between DONG Energy (50%) and its partners PKA (25%) and KIRKBI A/S (25%).
