Fugro will be undertaking a survey for unexploded ordnance (UXO) on behalf of Beatrice Offshore Windfarm Ltd (BOWL), across its wind farm development zone.
The UXO survey is scheduled to start during an appropriate weather window following September 1, 2016, and will continue over a planned minimum period of 8 weeks, weather permitting.
Fugro will carry out the survey with three different vessels: MV Fugro Helmert, MV Fugro Frontier and MV Fugro Meridian.
The vessels may not begin their activities at the same time but will likely operate simultaneously at times on the site over the survey duration.
The purpose of this survey is to carry out an investigation and removal of UXO ahead of the construction works at the site, including full high resolution UXO survey at the locations of all proposed wind turbine generator (WTG) and offshore transformer modules (OTMs), jack-up stand-off locations and along the inter array cable corridors in order to confirm that each site is free from potential UXO or other items that may pose a hazard to installation operations.
The routes of the inter array cables may subsequently be altered, where possible, to avoid the UXO, or the UXO will be removed if no alternate route is available. The UXO survey will involve the coverage of dedicated survey lines by the vessels with a full suite of geophysical survey systems (Multi beam Echo Sounder, Side Scan Sonar and Magnetometer) mounted on the vessel or towed from the stern of the vessel.
The vessels will be working 24 hour operations and will display appropriate day shapes and lights during reduced visibility and night operations, BOWL sad in notice to mariners on Monday.
