Project overview:

Tapered Spiral Welding for US Offshore Wind Turbine Towers

Awardee:

Keystone Tower Systems

Start Date:

Q3, 2021

Technical Challenge Area:

Fixed Structure Engineering

Completion Date:

N/A (Currently Underway)

Synopsis:

In this project Keystone will investigate the potential and feasibility of multi-wrap steel wind towers for offshore wind application. Keystone will work with OEMs, Johns Hopkins University, and Northeastern University to develop a spiral wrapped steel tower design as well as a flexible manufacturing process designed within US supply chain limits.

Target Outcomes:

Establish a baseline level of performance of Keystone’s spiral-welding technology in offshore applications, and to study and compare our experimental multi-wrap technology to that baseline.

Develop a manufacturing process suited to localized port, tow-out, and material supply conditions.
