Risk advisor 6 Alpha Associates has partnered with consultant Atkins to provide offshore unexploded ordnance (UXO) risk assessment ahead of the geotechnical surveys for three major offshore UK wind farms.
The companies worked in partnership to deliver UXO risk management services for the geotechnical ground investigations undertaken at the designated turbine locations, as well as along the export cable routes for the Galloper, Rampion and Triton Knoll projects.
Prior to specifying the geophysical surveys, 6 Alpha prepared desktop study reports to ascertain the level of initial UXO risk.
Once the absence of UXO had been confirmed by interpretation of the geophysical surveys, 6 Alpha awarded safety sign off certificates to confirm that the risk of UXO had been reduced to as low as reasonably practicable (ALARP) and geotechnical vessels could carry out exploratory boreholes.
“The future of offshore wind development depends on the ability of the industry to learn from previous projects. It’s why we’re becoming involved significantly earlier in the development timeline,” said Simon Cooke, managing director, 6 Alpha.
“By working with Atkins during the preliminary stages of offshore wind construction, we can ensure that the possibility of extensive and costly delays related to the discovery of UXO on site at a later date is avoided.”
