2.4 Blade-specific transportation logistics Information on the industry status for transportation of wind turbine components was obtained through numerous sources. Notable contributions include information provided by BNSF Logistics (BNSFL), Anderson Trucking Service, Inc. (ATS), other participants in the industry workshop [1], NREL studies [2], [3], and market data and insights from Wood Mackenzie and DNV GL. Land-based transportation infrastructure, primarily road and rail networks, have been used exclusively to enable off-site manufacturing of all wind turbine components with economically competitive transportation and delivery logistics. As wind turbine components and blades have increased in size over the past 30 years, the transportation industry has developed various innovations and solutions to manipulate these oversized and overweight loads across the nation. Thus far, wind turbine scale increases combined with the related transportation and delivery costs, have been able to achieve declining LCOE. However, achieving the next generation of supersized turbines (necessary to unlock both lower energy costs and expand wind energy development potential) requires further R&D to address new challenges of scale, manufacturing, and delivery. Today, the transportation industry and local infrastructure are handling wind turbines with the following broad dimensions: •

Rotor diameters: up to 134 m

Blade lengths: up to 67 m

Hub heights: up to 100 m (consisting of multiple steel tube sections of ~20 m long)

Drive train system: up to 3 MW

Turbines of this size are primarily being deployed across the central U.S. where existing road and rail networks are more capable of conveying oversized components. Transportation of current large-scale DNV GL – Document No.: 10080081-HOU-R-01, Issue: C, Status: FINAL www.dnvgl.com
