Fugro kicks off major cable route site investigation for Sofia offshore wind farm

Fugro's multipurpose vessel Fugro Pioneer left the Port of Sunderland in the UK earlier this month to kick off a 6-month offshore site investigation and survey campaign for innogy's Sofia offshore wind farm.


With a consented capacity of 1.4 GW, Sofia will be one of the world's biggest offshore wind farms; Fugro will provide geophysical and geotechnical services over the project's 220 km export cable corridor, in what is believed to be one of the longest cable route surveys ever performed for an offshore wind farm, as well as further works on the wind farm array.

The objective of Fugro's site investigation is to comprehensively characterise subsurface conditions along the cable route corridor to better understand the benthic ecology and offshore archaeology of the site, and to enable detailed design for the proposed wind farm, which is located 195 km off the coast of north-east England.

The site investigation will include surveys performed from five state-of-the-art vessels and will be complemented with a full suite of conventional and advanced laboratory testing. As well as Fugro Pioneer, geophysical survey data will be acquired using the Fugro Frontier and Fugro Seeker; two of Fugro's geotechnical vessels will then follow to provide drilling, and seabed sampling and in situ testing. Once the Geo-data is acquired, Fugro will produce a ground model for innogy that will provide standardised datasets and interpretation in a clearly identifiable and easy-to-access format.

"For Fugro, this project is an exciting opportunity for multiple vessels and multidisciplinary project teams to work together to provide an excellent service to innogy and support the Sofia team in achieving its objectives from the outset," said Sally Dalrymple, Senior Project Manager for Fugro.

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
