Icebreaker Offshore Wind Demonstration Project

Cuyahoga County, OH

Hull performed a geotechnical exploration for the 138 kV Interconnect and Switchyard Electrical Substation, power poles, and horizontal directional drilling pits related to the installation of six 3.45 MW wind turbine generators (WTG) located 8 miles offshore from the former Cleveland Public Power (CPP) Site and beyond the Breakwaters.

Energy generated from the WTG will be transmitted through cables installed beneath the harbor with horizontal directional drilling techniques.  Once completed, the system will be the first freshwater offshore wind farm in North America.

The purpose of the geotechnical exploration was to obtain geologic information and to determine relevant engineering properties of the Site soils to support in the design of the electrical substation and Horizontal Directional Drilling (HDD) entry pit.  As part of the exploration, Hull also obtained a better understanding of the historic filling activities (e.g., type of fill, approximate vertical/lateral extents, consistency/density, etc.) in the development areas and provided basic information relative to potential construction and development constraints, including their suitability for initiating a HDD bore from the Site and the possible presence of rubble or other obstructions.

A limited Environmental Review was completed to review available documents and environmental information for the site to better understand the general liability and risks associated with known environmental conditions.

Hull coordinated a geophysical exploration using Electromagnetic (EM) Induction profiling and targeted Ground-penetrating Radar (GPR) technology over targeted areas based on the proposed layout of the site to identify possible obstructions and determine the fill consistency.
